USAID ENERGY PROGRAM Cost Estimation Study of Gas Pipeline Network and Alternative Systems for High-Mountainous Settlements of Georgia 5

1. EXECUTIVE SUMMARY While urban areas in Georgia are adequately provided with necessary energy resources to meet the population’s household energy needs, many settlements in remote and high-mountainous areas are not, and some of them are still completely off-grid. The Government of Georgia (GoG) has been considering connecting all such settlements to natural gas network to meet their energy needs, specifically for heating, cooking and hot water. While natural gas is the most wide-spread source for the abovementioned uses in urban and suburban households, it is not given that natural gas will be the best way to meet energy demand of remote and high-mountainous settlements. Before moving forward with gasification1, the GoG will need to consider such crucial factors affecting economic viability of gasification, as settlements’ distance from gas mains, access roads and their condition, number of residents, willingness and ability to pay, etc. It is therefore essential to assess economic viability of gasification, as well as consider alternative energy sources though a comparative analysis in order to help GoG find an economically optimal solution.

According to clause 4 of the Decree of the Government of Georgia #791 dated April 5, 2019 on Measures to be implemented during 2019-2021 in Support of Gasification of the Georgian Population, Georgian Gas Transportation Company (GGTC) was tasked to evaluate feasibility of gasification of those villages that are included in the List of High-Mountainous Villages defined in the GoG Decree #671. Ministry of Economy and Sustainable Development of Georgia (MoESD) addressed USAID Energy Program to assist them in developing a study that would group 966 villages into clusters according to an agreed-upon criteria, carry out Cost-Benefit Analysis (CBA) of gasification for each cluster, and provide recommendations on alternative energy sources for those clusters where gasification could not be economically justified due to a negative impact on tariffs, lack of profitability or some other reason.

The settlements were grouped by municipality, therefore creating 38 distinctive clusters, and each cluster was analysed separately. The decision to cluster the settlements by municipalities was agreed with GGTC and was based on the rationale that it would be the optimal way to present the costs and it would be the easiest for the Government to carry out gasification (if decided) gradually or simultaneously in individual municipalities. In addition, since majority of information - number of customers, energy use trends, available resources, budgetary funds, etc. is available on municipal level, it was deemed most sensible to carry out cost-benefit analysis for individual municipalities.

In order for USAID Energy Program to perform an accurate cost-benefit analysis, it was necessary to have an adequate estimation of gasification costs, including the cost of laying gas mains and building local networks for the selected settlements. For this purpose, USAID Energy Program engaged a Georgian gas pipeline and network design and engineering company to develop the estimates. The subcontractor provided schematic drawings of gas pipes including mains and local networks for the provided settlements; technical parameters of the pipes including length, diameter and material; and cost estimates for gasification of each cluster including mains, connection points and local network costs, detailed to each settlement.

CBA was conducted for each cluster based on the provided cost estimates. The study showed that gasification costs vary significantly among clusters due to several factors, including distance from gas mains, geographical location, terrain, type of soil, etc. Therefore, a unified approach cannot be used for all clusters, and the decision on gasification or provision of energy through alternative sources should be made individually for each cluster. The alternative options overviewed in this report include:

Table 1: Natural Gas Alternatives

Electricity subsidies GoG could subsidize electricity for heating and cooking

Biomass

Biomass boilers have higher efficiency than traditional wood stoves and can operate on different types of biomass, including wood logs, wood chips, pellets, and plant-based biomass. Biomass can fully substitute natural gas usage

1 To avoid misunderstanding we note here that in standard engineering literature the term “gasification” has a different meaning, however in this report it describes delivery of natural gas through gas pipeline system and is established term in Georgia and neighboring countries.


Solar Photovoltaics (PV) with Battery Energy Storage System (BESS)

Solar PV, solar-thermal, and/or solar-hybrid systems can be used either independently or in conjunction with other technologies, e.g. heat pumps to meet energy demand

Heat pump

• Grid connected

• Powered by PV+BESS

A heat pump is a device that works on refrigeration cycle, transferring thermal energy from environment such as ground, air and water reservoirs to a desired destination

Wood Stoves Wood stoves are traditionally used in Georgia for space and water heating as well as cooking purposes

Compressed Natural Gas (CNG) virtual pipeline

Transportation of natural gas in a compressed form and distributing using a pipeline that’s not connected to the grid

The above-listed alternatives were compared to natural gas through a comparative Life-Cycle Cost Analysis (LCCA) in order to capture all costs associated with each technology throughout the projection period – 35 years, including initial, replacement, maintenance and energy costs. When looking purely from cost standpoint, the analyses showed that gasification is not economically viable, failing to achieve a positive Net Present Value (NPV), or acceptable Internal Rate of Return (IRR) in any of the clusters. Despite this, gasification still is the most-cost efficient solution in a few municipalities as compared to most of the alternatives, with only the biomass-based technologies - biomass boilers and energy efficient (improved) wood stoves having lower Life-Cycle Cost (LCC) in all instances. Additionally, It is important to consider that alternatives, especially those that are not grid-connected will not create an upward pressure on natural gas tariffs, will not be dependent on imported energy resources and may therefore be a better solution when looking at other aspects besides cost, like energy security, environment and social welfare. The results of CBA and LCCA along with assumptions and inputs used for calculations are described in detail in Sections 3 and 4 below.

This report provides an overview of the gas sector in Georgia as it relates to natural gas usage by households, describes the methodology applied to CBA and LCCA, and provides findings and recommendations towards decisions to be made with regards to gasification and alternative energy sources.


2. BACKGROUND Despite being almost completely dependent on imports (local production of natural gas accounts for only 0.36% of total national demand), natural gas is a major energy source for Georgia and accounts for approximately 33% of total energy consumption. Share of natural gas in total energy consumption is growing slowly but steadily:

Figure 1: Energy Balance of Georgia2

Georgian population uses natural gas mainly for cooking, space and water heating purposes. The increase of natural gas consumption in the residential sector in recent years has been driven by the process of gasification as well as installation of higher capacity equipment (central water heaters) by population. While gasification process contributes to increase in consumption mainly in rural areas, increase in consumption in urban areas is mainly driven by the upgraded, higher capacity equipment. Recently introduced stricter safety regulations on natural gas equipment and proactive enforcement of these regulations by distribution companies will result in more consumers switching to central heating boilers, subsequently resulting in further increase in natural gas consumption.

Natural gas consumption trends differ by urban and rural areas, as well as by regions. In rural areas, with few exceptions, firewood is still the main source for space and water heating, and cooking, therefore natural gas consumption is lower.

As shown in Figure 2, Mtskheta-Mtianeti and Adjara are exceptions. The reasons behind this in Mtskheta-Mtianeti is that natural gas cost is subsidized by GoG, as well as the cold-climate and scarcity of firewood. As for Adjara, developed tourism is the main reason.

GoG has been moving the gasification process forward. In the last three years, number of households with access to natural gas has increased by 7.85% on average year-on-year, resulting in a total of 1,116,217 households with access to natural gas by 2018.

Figure 3: Number of Households with Access to Natural Gas

This escalating trend will continue as approximately 74,000 additional customers will have access to natural gas within the 2019-2021 period, according to GGTC and as stipulated by GoG decree.

As a result of GoG’s gasification efforts, Georgia has one of the highest levels of gasification in Europe.

Serbia 2,421,379 270,470 11.2

Despite the progressing gasification process, over 2,200 settlements in Georgia still do not have access to natural gas grids. GoG’s gasification efforts are motivated by the goal to provide access to reliable energy for all household throughout Georgia and alleviate energy poverty in the process, but other factors such as ability and willingness to pay hinder successful achievement of GoG’s goal in this regard. According to Georgian National Energy and Water Supply Regulatory Commission’s (GNERC) 2018 Annual Report, share of households with access to natural gas that do not consume it (non-active customers) is quite high:

Households with natural gas access


Figure 4: Number of Active and Non-Active Customers in 20184

In addition to willingness and ability to pay, other factors such as abandoned and seasonal dwellings also contribute to the big number of non-active customers.

This is an important issue that must be considered when making the decision on gasification and when considering alternatives. This negative statistic is further compounded by the fact that under current legislation, customers only pay when they consume and there is no fixed component in the tariff, therefore denying the distribution licensees the ability to fully recover their costs.

Other important factor for consideration is environment - natural gas is a fossil fuel based energy carrier and has greater adverse impact on climate as compared to electricity derived from renewable sources, as is the case in Georgia, or other renewable sources like biomass, solar PV and heat pump. This point must also be taken into consideration when making the decision, as substituting fossil-based sources with renewable sources would be a positive step toward meeting Georgia’s international commitments to reducing Greenhouse Gas (GHG) emissions under the United Nations Framework Convention on Climate Change (UNFCCC) Paris Agreement, Low Emissions Development Strategy (LEDS), European Union’s (EU) Covenant of Mayors, etc.

Increasing dependence on natural gas imports in a generally volatile region is another major issue worthy of consideration that directly relates to Georgia’s energy security.

These issues, along with others, are the main reasons why GoG addressed USAID Energy Program to carry out CBA and provide analysis of alternative energy sources before moving forward with gasification of high-mountainous settlements.

3. METHODOLOGY Objective of this study, as set by MoESD was to carry out cost-benefit analysis of gasification for high-mountainous settlements (settlements) of Georgia, and where gasification was not deemed financially viable, propose alternatives. USAID Energy Program divided the analysis into two components: 1) Cost Benefit Analysis; and 2) Life-cycle Cost Analysis. The purpose of CBA was to evaluate financial viability of gasification through analysing such essential financial metrics as NPV, IRR and Payback Period (PB); potential impact on natural gas tariff was also evaluated. For the purpose of comparing alternatives, USAID Energy Program chose the LCCA method. LCCA allowed USAID Energy Program to capture all costs associated with installation and utilization of various technologies throughout the planning horizon, including cost of equipment with installation, replacement cost, operation and maintenance costs and energy costs required to run the equipment (if subsidization is required). The planning horizon was set at 35 years. Assumptions and inputs for CBA and LCCA are described in sub-chapters 3.1 and 3.2 of this section.

As the first step, USAID Energy Program needed to determine baselines in terms of gasification cost and energy consumption. Adequate estimates of the gasification costs were necessary to carry out an accurate CBA; to this end, USAID Energy Program in consultation with GGTC selected and subcontracted a local firm – Tsisferi Ali (the contractor) specializing in natural gas pipeline and network design and cost estimation. USAID Energy Program, together with the contractor and GGTC grouped the 966 settlements into their respective municipalities, creating 38 clusters. Table 3 below provides the list of clusters, number of settlements and population within each cluster.

However, as the cost-estimation effort was underway Kazbegi was dropped from the list, as it became evident that there was only one settlement in this municipality, which was already gasified, therefore the analyses were conducted for 37 clusters. The nature of estimating gas pipeline and network costs dictated that, costs for other, non-high-mountainous settlements, which were on the way to, and in the vicinity of subject settlements also needed to be calculated in order to accurately estimate all costs associated with connecting the settlements to gas network. As a result, cost-estimation was done for 1,171 settlements. The cost-estimation study provided schematic drawings of gas pipes including mains and local networks; technical parameters of the pipes including length, diameter and material; and cost estimates for gasification of each cluster including mains, connection points and local network costs, detailed to each settlement. A sample cost-estimation study can be viewed in Annex 1.

As for gas consumption numbers, they were derived from GNERC’s Annual Report from 2018 as shown in Figure 2 above, and CBA and LCCA calculations for each cluster were tailored according to the natural gas consumption figures in those regions where clusters are located.

Table 4: Estimated Annual Consumption for Each Cluster

3.1 COST BENEFIT ANALYSIS

An accurate CBA study needed the estimation of a total annual consumption in each cluster. Therefore, in addition to per household consumption provided in Table 4, the study incorporated the number of active households in each cluster. Respective data was collected from various sources. Data obtained from the Ministry of Infrastructure and Regional Development of Georgia (MRDI) comprised of both high and low mountainous settlements in all municipalities. Energo-Pro Georgia provided data on active consumers in each low and high mountain settlements for the last 24 months. This piece of information contributed to classification of seasonal consumers from all settlements and enabled the accurate calculation of active number of consumers in each municipality.

The two variables - average annual household consumption and the number of active consumers allowed the Program to calculate the expected gas consumption in all locations.

The multiplication of the number of active consumers by the annual gas consumption of one household reveals the total gas consumption in meter cubes for that particular municipality.

To identify the municipalities suitable for the gasification projects, both from the economic and financial perspectives, cost benefit analyses should be conducted for each location in view of installation cost (initial investment), cash inflows and outflows for each following year.

Based on available studies, the lifespan of gas pipeline is 35 years, therefore this number has been applied in the calculations.

For the purpose of comparative analysis and consistent comparison of municipalities different financial indicators were used: IRR, NPV, cost per consumer and payback period in combination with various assumptions.

The applied discount rate 13.5% was based on GNERC’s methodology for calculating the Weighted Average Cost of Capital (WACC) for gas projects; gas consumption for each municipality was calculated separately in line with the above provided methodology (consumption per household was taken from GNERC annual report which is different among municipalities and varies in the range of 321-1247 cubic meters per year); gasification tariff was taken 20 tetri for each cubic meter based on SOCAR Georgia and Saqorgaz tariffs, and we assumed the annual escalation of the tariff by 1%, maintenance cost per kilometre of gas pipeline per year was set at GEL 3,000 based on consultations with GNERC, natural gas demand annual growth rate was assumed at 5%, based on the approximate Gross Domestic Product (GDP) growth rate. Based on these assumptions IRR, NPV, cost per consumer and payback period were calculated for each municipality and compared, which enabled us to correctly asses each direction.

The main limitation of the study is time constraint. High mountain settlements are spread among 37 different municipalities and due to diverse geographical location, nature and climate conditions, etc. the above discussed variables will vary in all 37 municipalities. However, the shortage of time does not allow conduct separate research for each municipality.

Based on collected data the Program conducted cost benefit analysis separately for each municipality. The analysis process also included other villages located between high mountain settlements. In total 1,178 settlements were studied in which 973 are high mountain villages. There are 87,725 households in which 53,788 are from high mountain regions. We have different variables in our data: number of consumers, number of villages, instalment cost, length of the pipeline. All these variables were calculated separately for each municipality. The majority of variables are fixed, hence do not vary in municipalities: project duration, tariff, maintenance cost, discount rate, demand growth rate, tariff growth rate. Only gas consumption per household varies among municipalities due to climate conditions and other factors (in Mestia municipality electricity is free and in case of gasification demand on gas will be lower compared to other high mountainous parts of Georgia).

For accurate evaluation of different municipalities, the Program compared separate key parameters for each destination. IRR was applied for each location to evaluate the profitability of the project. “IRR is a metric used in capital budgeting to estimate the profitability of potential investments”. Another pivotal aspect NPV aided in investment assessment. (NPV) is the difference between the present value of cash inflows and the present value of cash outflows over a period of time. The Program also reviewed the payback period to find the breakeven point for each location. “The payback period refers to the amount of time it takes to recover the cost of an investment. Simply put, the payback period is the length of time an investment reaches a breakeven point”.

In addition to the key financial indicators, other basic variables have been applied in the study, since Gasification Study claims more comprehensive approach rather than sole focus on the financial ratios. Gasification of high mountain villages can be considered as a social project, with the focus on the number of consumers in each municipality, number of villages in each direction and an installation cost per consumer.

The combination of all variables will serve as a valuable input for the accurate assessment of investments in each municipality.

3.2 LIFE-CYCLE COST ANALYSIS

USAID Energy Program chose the LCCA method to compare cost-efficiency of various alternative energy sources to gasification. LCCA was deemed as the most suitable tool, as it enabled USAID Energy Program to capture all costs needed to purchase, own, operate, maintain and replace various technologies and/or services. Since the analysis was done at GoG’s request, all costs were analysed from GoG standpoint, i.e. how much would it cost the government to install, operate, maintain and replace the various alternatives over the 35-year period. The details of general assumptions based on which the LCCA model was built are described in section 3.2.1 below. The alternatives that were analysed are:

• CNG Virtual Pipeline

• Electricity Subsidies

• Biomass


• Solar PV with BESS

• Heat Pump o Grid-connected o Off-grid (powered by PV+BESS)

• Wood stoves

Description of each alternative, assumptions and calculations are provided in the respective sub-chapters of this chapter.

3.2.1 LCCA MODEL INPUTS AND ASSUMPTIONS

As the first step, USAID Energy Program needed to establish a baseline volume of energy required by households to meet their cooking, space and water heating demand. For this purpose, USAID Energy Program used the average annual natural gas consumption numbers provided in Table 4. Efficiency factor of 75% was used to derive required energy from consumption numbers, meaning that from every cubic meter of natural gas consumed, the households receive 0.75 cubic meters of usable energy. This assumption was based on the efficiency factors of the most widely used heating devices in Georgia: “Karma” individual space heater, individual water heaters and gas stoves. Efficiency factors for these devices vary from 87 to 95%, and 75% was used for calculations to account for system losses and based on consultations with MoESD. USAID Energy Program then calculated average annual required energy (cubic meters of natural gas) per household for each cluster:

Figure 5: Annual Energy Required per Household – M3

To make the process of comparing different technologies that use different sources of energy straightforward, USAID Energy Program converted the natural gas numbers into Kilowatt hours (kWh). The following coefficients were used to express one cubic meter of gas into kWh:

1 Cal = 4.19 J

1 Wh = 3,6 KJ

1 kWh = 3.6 MJ

1 MJ = 0.2778 kWh

Where:

• Cal = calorific value of m3 of natural gas

• J = Joules

• KJ = Kilo joules

• MJ = Mega joules

• kWh = Kilowatt hours

From these coefficients it follows that one Kilocalorie (Kcal) of gas equals 4.19 KJ, and since average calorific value of m3 of natural gas in Georgia is 8,495.25 Kcal5, one m3 of natural gas equals 35,595.10 KJ and equals 9.89 kWh (35,595.10 / 3.6 /1,000).

As USAID Energy Program established the baseline figures, additional general assumptions were made to generate the LCCA model.

GENERAL ASSUMPTIONS

Planning Horizon: 35 Years All costs are calculated for the duration of planning horizon

USD/GEL exchange rate: 2.95 Used to calculate cost of various technologies, where relevant prices in Georgian Lari were not available

Energy carrier prices:

- Natural Gas 0.5694 GEL/m3 Current SOCAR tariff. Since all settlements are in the regions SOCAR tariff was deemed most suitable.

- Electricity 0.2273 GEL/kWh

Current Energo-Pro tariff. Since all settlements are in the regions Energo-Pro tariff was deemed most suitable.

- Biomass (wood logs) 100 GEL/m3 Current market price of air-dried wood logs in Georgia

For base case, USAID Energy Program assumed that GoG will fully subsidize household energy costs, except for those cases where an off-grid technology is installed. This assumption was predicated on the fact that majority of the settlements are high-mountainous rural settlements, with very poor economic conditions. Employment rate amongst high-mountainous population is only 22%. Main income for households is pension and government subsidies. Maximum monthly income for 35% of households is up to GEL 2506. USAID Energy Program developed an additional scenario where GoG does not provide subsidies (Scenario 2).

As for estimating the installation and maintenance cost of proposed alternatives, USAID Energy Program based them on local market prices, where available, and used international market prices, if the technologies were not available locally.

The formula to calculate the life cycle cost of each alternative is as follows: LCC = Installed cost + Replacement cost + (Operation and Maintenance (O&M) Cost + Energy cost) x Number of years

Where:

Installed cost is the total GEL amount required to purchase and install the equipment;

Replacement cost is the same as installed cost but is calculated only if useful life of a particular technology is less than the planning horizon. Replacement cost is proportioned to reflect the cost to be carried only within the planning horizon. For example, if a particular technology’s useful life is 20

years, than replacement is required on the 21st year of utilization and the replacement cost is proportioned for the remaining years, in this case:15 (planning horizon – useful life, i.e. 35 – 20 = 15);

O&M Cost is annual operation and maintenance costs required to keep the equipment fully operational;

Energy cost is calculated only in case subsidization is required, i.e. if a particular alternative is either grid connected and requires subsidization of electricity, or if in case of biomass (Biomass boilers and woods stoves), GoG decides to cover the cost of the biomass itself, e.g. wood logs. If required, energy cost is calculated by multiplying the volume of required energy by the price of the respective energy carrier.

Number of years is the planning horizon, in our case 35 years.

The sum of annual O&M and Energy Costs is multiplied by the number of years in the planning horizon to get the full cost of operating and maintaining each alternative throughout 35 years.

The LCCA model allows changing of each variable to be able to accommodate virtually unlimited number of assumptions and scenarios.

USAID Energy Program made additional assumptions specific to each alternative, described below.

COMPRESSED NATURAL GAS VIRTUAL PIPELINE

CNG is natural gas stored and transported in a compressed form, that reduces the volume by 150-300 times that of gas at atmospheric pressure.

Figure 7: CNG Virtual Pipeline Scheme

The on-land transportation of CNG has been used for decades, and it consists of gas compression and truck loading at the location and truck offloading, heating, let-down and metering at the customer site.

To calculate the LCC, USAID Energy Program asked SOCAR Gas Distribution Company to provide estimates for CNG virtual pipeline for three locations. SOCAR provided the following estimates:

• Sakire: EUR 700,000

• Mestia: EUR 1,700,000

• Atskuri: EUR 700,000

According to SOCAR these estimates are very tentative and do not factor in several important points like O&M costs, access road conditions and difficulty, etc.

Unfortunately, numbers provided by SOCAR lacked the level of detail required to calculate the LCC, therefore USAID Energy Program could not include CNG virtual pipeline in the comparative LCCA.


ELECTRICITY SUBSIDIES

One of the widespread alternatives to natural gas for household consumption, is electricity. Even though electricity is more expensive to use for cooking, space and water heating purposes, it is more widely available throughout Georgia and will not require initial investment and time to cover the population’s energy needs. For the purpose of LCCA, USAID Energy Program assumed that instead of investing in gasification, GoG would fully subsidize the cost of electricity to households. To calculate the LCC, USAID Energy Program used the following assumptions and calculations:

Energy cost was calculated by multiplying the required volume of energy in kWh as indicated in Figure 6 above by 0.2273 GEL/kWh tariff.

Installed, replacement and O&M costs. Since electricity is accessible by majority of households, and it was assumed that GoG would not cover the cost of purchasing relevant household equipment, installed, replacement, and O&M costs were zeroed out.

As a result, the LCC of this alternative was calculated by simply multiplying annual energy cost by 35 (planning horizon). Despite this, electricity subsidies still came out as a more expensive alternative to gasification in 57% of the clusters in Scenario 1 and 68% in scenario 2.

BIOMASS BOILER

Biomass boilers can run at efficiencies of 90% and are commonly used to meet households’ hot water and heating needs. Biomass boilers are much more efficient than traditional wood stoves and can be operated unaided for extended periods of time therefore making it a more sensible choice for households. Moreover, biomass boilers increase comfort-level of households by being able to power central space and water heating systems, as opposed to wood stoves.

Biomass boilers can operate on all kinds of biomass. Biomass is any biological material that is used as fuel. Wood and its byproducts, leaves, plant-based biomass, agricultural waste and dried animal dung all belong to biomass fuels. Directly burning wood produces air polluting substances such as carbon dioxide and soot, therefore it is preferred to process biomass before burning it. There are different types of wood biomass products such as wood pellets, briquettes and wood chips which are pressed and given shape for easier transportation, storage and better heating qualities. For the purpose of LCCA, USAID Energy Program assumed that majority of households will be using most widely spread type of biomass in Georgia – wood logs.

To calculate the LCC, USAID Energy Program used the following assumptions and calculations:

Installed Cost was determined by calculating required installed capacity of the boiler (expressed in kW). To do so, USAID Energy Program analysed local and international cases: Department of Energy and Climate Change of UK completed an extensive survey of biomass boilers in the UK, and provided actual outputs of biomass boilers in various capacity bands:

Table 5: Average Annual Output of Biomass Boilers

The numbers in Table 5 above are actual produced energy documented through a survey in UK, therefore all system losses are considered.

Although the overall average output per kW came out to 1,530 kWh, lower capacity boilers seem to be less efficient, therefore we used an average number of the 1-44 kW capacity band – 1,138 kWh per kW installed for our calculations. For additional certainty a biomass boiler installed in Georgia’s Pshaveli Village at local Kindergarten (a 600 m2 building) was analysed as well. In this case, claimed annual output of the installed 60 kW capacity boiler is 72,000 kWh, which comes out to an output of 1,200 kWh per installed kW and is in line with our assumption. The required energy for each cluster

Capacity Band (range) Boiler Installed Capacity (kW) Mean Annual Heat Output (kWh) Average output Per kW Installed (kWh)

1‐44 kW 30 34,136 1,138

101‐150 kW 132 157,248 1,191

151‐199 kW 191 313,848 1,643

200‐400 kW 326 349,724 1,073

401‐600 kW 510 945,816 1,855

601‐800 kW 746 1,120,844 1,502

801‐1000 kW 942 2,171,380 2,305

Overall average 1,530


(Figure 6) was then divided by this number to arrive at required installed capacity. e.g. for clusters within the Adjara Region the required installed capacity came out to 5.2 kW (5,897 kWh / 1,138 kWh).

Further, to determine the cost, two local cases - Pshaveli case mentioned above and Natakhtari case were studied. Both cases were implemented by USAID funded projects. In Pshaveli’s case cost per kW installed equalled $255, and in Natakhtari’s case $187.50 per kW with the average of two prices being $221.25/kW. USAID Energy Program used $220/kW for calculating the Installed cost. So, in the example of Adjara region, total installed cost of the biomass boiler equals 5.2 kW x $220 = $1,140.

Replacement Cost was proportioned for 15 years, since useful life of biomass boilers is estimated at 20 years.

O&M Costs for biomass boilers are generally very low, requiring an annual visit of a technician to clean the system. Therefore GEL 100 per year was assumed.

Energy Cost was estimated by determining the required volume of wood logs (m3) and multiplying the determined number by local prices per m3. As all calculations are done on a kWh basis it was necessary to determine the required energy input in kWh. Since average efficiency of biomass boilers is 90% as mentioned above, required energy input was calculated by dividing the required energy numbers from Figure 6 by the 90% efficiency factor. The resulting number was then converted into GJ using the 277.78 GJ to kWh ratio. Energy density of biomass in Georgia was determined through National Statistics Office of Georgia (Geostat) annual publication – Energy Balance of Georgia 2017. According to statistics provided in the report, average energy density of m3 of biomass, specifically wood logs was calculated at 7.8 GJ/m3. This coefficient allowed us to calculate annual total volume of wood logs in m3 required to run the biomass boiler of a determined capacity for each cluster. Average current cost of m3 of wood logs was estimated at GEL 100 based on online research.

It is worth noting that biomass boilers cannot be used for cooking, therefore USAID Energy Program assumed that the households will continue using their current sources and appliances for cooking and will not require subsidies, since the energy cost for cooking alone, be it electricity, Liquefied Petroleum Gas (LPG), wood or other energy carriers, would be marginal.

SOLAR PHOTOVOLTAICS COUPLED WITH BATTERY ENERGY STORAGE SYSTEMS

Solar PV is a technology that produces electricity directly from sunlight. The electricity produced by PV can be used to charge batteries or to directly power household electrical devices with the help of an inverter, PVs can also be connected to electrical grids through a net metering arrangement. For our model, we calculated LCC of PVs in combination with BESS, since there is a limitation on a total combined capacity of grid-connected distributed generation systems within a distribution network.

While it would be extremely cost-inefficient to power space and water heating devices exclusively through PVs, USAID Energy Program still calculated the cost of PVs for such applications for comparative analysis and for estimating the cost of PVs to consider coupling it with other technologies like heat pumps.

To calculate the LCC of PVs USAID Energy Program used the following assumptions and calculations:

Installed Cost was calculated by determining the required installed capacity of the PV and battery systems and multiplying it by the current cost of such systems locally. USAID Energy Program used the GoG’s ongoing “Solar PV for Off-grid Settlements” program as a reference to determine the costs.

Since USAID Energy Program already estimated the required energy for each cluster, the required installed capacity was then calculated by using the following global formula:

E = A x r x H x PR

where:

E = Energy (kWh) A = Total solar panel area (m²) r = solar panel yield (%) H = Annual average irradiation on tilted panels (shadings not included) (kwh/m2) PR = Performance ratio, coefficient for losses (range between 0.9 and 0.5).

Since energy was our main, pre-determined variable, the formula was adjusted to calculate the area and from there the total required installed capacity expressed in Kilowatt peak (kWp). To calculate the kWp a simple formula of A x r is used. As for estimating other variables of the formula: solar panel


yield was estimated at 19% (referencing the GoG program mentioned above), Annual average irradiation was estimated for each cluster by referencing the irradiation map of Georgia:

Figure 8: Irradiation Map of Georgia7

PR was estimated at 0.75 with details of estimated losses as follows:

- Inverter losses: 8% - Temperature losses: 8% - DC cable losses: 2% - Ac cable losses: 2% - Shadings: 3% - Losses, weak irradiation: 3% - Losses, dust, snow: 2%

With all variables in places, USAID Energy Program calculated total required installed capacity for each cluster and multiplied it by the price of $3,300 per installed kW of PV modules and BESS. As mentioned above the price was taken from GoG’s ongoing program, therefore it should be reflective of realistic and up to date prices of such systems locally.

Replacement Cost was proportioned for 10 years, since useful life of PV system is estimated at 25 years.

O&M Costs were set at zero, as USAID Energy Program assumed that households will be cleaning the PV modules themselves and will not encounter any breakdowns.

Energy costs were also set at zero, as PV + BESS systems are autonomous off-grid systems and do not require energy input from outside sources to run.

HEAT PUMP

Heat Pump is a highly efficient device that works on refrigeration cycle to transfer thermal energy from environment such as ground, air and water to a desired destination. A simplified heat pump consists of a condenser, expansion valve, evaporator and a compressor. There are several types of heat

7 Source: Solargis.com


pumps that are mainly differentiated by the source where they take the heat from – the main types of heat pumps are air-source, geothermal (ground-source) and water source.

For this study, USAID Energy Program concentrated on air-source heat pumps, specifically air to water type. Although ground and water-source heat pumps may be slightly more efficient in some cases, the cost of these type of heat pumps is very high, since their installation requires ground works, and therefore is very cost-inefficient for households.

Air to water heat pumps take heat from the outside air and transfer it to a water-based system. The created heat can be used for space heating or as a hot water supply for the house. Air to water heat pumps are among the most efficient air source heat pumps on the market. Their Coefficient of Performance (CoP) ranges from 200% to 420%, meaning that for every 1 kW consumed the heat pump outputs anywhere from 2kW to 4.2 kW energy. This type of heat pump works best in moderate climates. The efficiency of an air to water heat pump is most optimal at 7°C, as opposed to dry and cold locations, where outside temperatures fall below -20°C. Keeping the working principles of an air to water heat pump in mind, the decline in temperatures will affect the coefficient of performance.

USAID Energy Program considered two cases for heat pumps, grid connected, and PV powered. Grid connected heat pumps draw required power from electricity grids, whereas in case of PV-powered heat pumps PV modules and batteries will also be installed to power the heat pump.

To calculate the LCC USAID Energy Program used the following assumptions and calculations:

Installed Cost was calculated by determining the required energy output of heat pump systems and researching the cost of such systems locally. As mentioned above two cases were evaluated – 1) grid-connected and 2) PV powered. In the 1st case only the installed cost of heat pump was considered, and in the 2nd case installed cost of heat pump together with PV and battery modules was calculated. PV and battery installed costs were estimated using the same assumptions and calculations as for standalone PV and battery modules described above. As maximum required energy was estimated at 9,250 (for clusters in Mtskheta-Mtianeti Region), it was determined that a heat pump with maximum rated output capacity of 6 kW would be more than enough and could accommodate for decreased coefficient of performance in cases of extreme temperature variations. The cost of such heat pump was assumed at GEL 10,000 based on local market research. As for estimating the cost of PV modules, their installed capacity was determined based on energy required by heat pump for each cluster, estimated by looking at average annual temperatures in the region where cluster is located. After finding out the lowest average annual temperature in each region, coefficient of performance of heat pumps was adjusted accordingly, allowing Energy Program to establish volume of energy required to power the heat pump in clusters within different regions. For

example, in Adjara region lowest average annual temperature is -6 C0 (Degrees Celsius).

Figure 9: Average Annual Temperatures in Adjara Region - 2018

Heat Pump’s CoP was adjusted to 340% for all clusters within Adjara region according to the gradation scale shown in table below:

Volume of energy required to power the heat pump was then established by dividing the required energy output – 5,897 kWh in Adjara’s case, by CoP – 340%, 5,897 / 340% = 1,734 kWh. This number was then used to size and price the PV and battery system for various clusters.

Replacement Cost was proportioned for 10 years, since useful life of heat pump, as well as PV system is estimated at 25 years.

O&M Costs for heat pump were set at annual GEL 30/kW (capacity), based on international experience. PV’s O&M costs were set at zero, as USAID Energy Program assumed that households will be cleaning the PV modules themselves and will not encounter any breakdowns.

Energy cost was calculated by multiplying the required volume of energy in kWh as calculated for each cluster by 0.2273 GEL/kWh tariff. In case of PV powered heat pump energy cost was set at zero, as PV + BESS systems are autonomous off-grid systems and do not require energy input from outside sources to run.

As in the case of biomass boilers, heat pump cannot be used for cooking, therefore USAID Energy Program assumed that the households will continue using their current sources and appliances for cooking and will not require subsidies.

WOOD STOVES

The current wood stoves available in Georgia are inefficient, poorly made, do not meet consumer desires, require continuous tending, and do not meet basic safety requirements. Moreover, because there are no other options, there is a significant amount of wood use in rural Georgia. Absolute majority of heating stoves used in rural Georgia are of the same basic design, and the estimated efficiency of these stoves is no more than 30 to 50%. Because of the relatively high costs for heating, there should be significant consumer interest in higher efficiency stoves. For LCCA, USAID Energy Program assumes that GoG will replace inefficient stoves with higher-efficiency wood stoves and subsidize the cost of fuelwood to the population. In ideal case, it would be best to install stoves with 75% efficiency, but since such stoves are not available on the local market, USAID Energy Program assumed that GoG will procure and install “Svanetian” type wood stoves at households, with estimated efficiency of 55%.

USAID Energy Program used the following assumptions and calculations to calculate the LCC of woods stoves:


Installed Cost is the cost of procuring the Svanetian type wood stove. Online research of local market showed that such wood stoves cost GEL 450 on average.

Replacement Cost was proportioned for 20 years, since useful life of a wood stove is estimated at 15 years.

O&M Costs were set at zero, as wood stoves require almost no maintenance and rarely break down.

Energy Cost was estimated by determining the required volume of wood logs (m3) and multiplying the determined number by local prices per m3. Same method was applied here as in the case of biomass boilers. Average current cost of m3 of wood logs was estimated at GEL 100 based on online research.

It is worth noting that although wood stove is the lowest cost option, even if cost of fuelwood is fully subsidized by GoG, wood stove provides very low level of comfort, cannot be used to centrally heat space and water and is generally the least attractive option in terms of comfort and safety.


4. FINDINGS AND RECOMMENDATIONS

Based on the assumptions and calculations described above, USAID Energy Program developed CBA and LCCA models. The results and findings of the analyses are provided below.

4.1 CBA FINDINGS

The main purpose of this study was to conduct the cost-benefit analysis for high-mountainous settlements. Due to complex landscape of Georgia, there are many settlements located on the way to, or in the vicinity of high-mountainous settlements.

The construction of gas pipeline in high mountainous settlements will require passage through certain low mountainous settlements as well. As noted above, Gasification project is of a social character, therefore avoidance of settlements located in the vicinity of high mountain villages is inappropriate. In addition, the gasification of low mountain villages is justified by cost benefit analysis. Data assessment showed that it will decrease the gasification cost per consumer in 29 municipalities (out of 37) and increases the IRR in 36 municipalities (out of 37). This study also calculated the NPVs for each municipality which remains negative in both cases of high and low mountainous settlements.

It should be mentioned that a big portion of gasification cost is fixed, which includes the construction of the main pipeline directed to that municipality (In Mestia municipality cost of the building pipeline from Zugdidi to Mestia is 72% of the whole cost and in Tskaltubo municipality respective share of the cost is 80%) . An increased number of consumers within municipality decreases cost per consumer due to economies of scale and increases IRR of the project.

NPV in millions GEL


The graph above demonstrates the NPVs of gasification projects which remain negative for all municipalities. On average NPV is minus GEL 18 million for one municipality, while for Mestia municipality, it accounts for -106.4 million and for Mtksheta -1.3 million.

Based on the NPV analysis the project does not seem lucrative, unless the projects are separately considered as private investment projects. The results prove that the projects are not commercially viable and only in 7 municipalities investor will lose less than 5 million.

Figure 11: IRR by Cluster

The graph above shows the IRR analyses for each municipality. The gasification projects reveal similar negative NPVs for municipalities which discourages the comparison of IRRs as the negative NPVs is enough justification for arguing the economic inefficiency of the gas pipe construction in high mountainous municipalities. Only 5 municipalities have positive IRR. The highest observed IRR is in Akhaltsikhe municipality accounting for 4.6% and even in case of ignoring the negative NPV, it is not viable as 4.6% IRR means that it will be more profitable to put this money on a deposit in the commercial bank, because profitability of investment in this case will be definitely more.

Figure 12: Gasification Cost by Cluster

Two graphs above demonstrate the cost of gas pipeline construction in million GEL and the cost of gasification per consumer. The most expensive location is Mestia municipality and building pipeline to that direction costs 95 million Gel. Mestia is also the worst option based on the NPV indicators and in terms of cost per consumer (28,500 Gel). The right side of the graph shows the cost of building gas pipeline network per consumer, which differs significantly within municipalities max 31,700 Gel in Gurjaani caused by the low number of potential consumers (37 only) and minimum 2,900 Gel in Chiatura.

Building cost of Gas Pipeline in million GEL


The table above shows the summary of each variable for all 37 municipalities. The worst-case scenario is building the gas pipeline towards the Mestia municipality, with NPV negative 106.4 mln GEL. The best direction for building the gas pipeline is Mtskheta municipality with NPV 1.4 mln GEL. This is attributed to the lowest length of pipeline which might be built in Mtskheta Municipality and by the highest consumption of gas per consumer in this location (1247 cube meters per family during year). The IRR on average is negative 3% and even the highest IRR, positive 4.6% is not acceptable due to its low profitability. The Lowest cost per consumer is in Chiatura GEL 2,903, the shortest payback period is 23 year for Akhaltsikhe municipality, and the shortest length of building pipeline is in Telavi.

It is evident from the graph, that we have municipalities with 128 settlements (Mestia) and municipalities with 3 villages (Gurjaani). This can be explained by the total absence of gas in Mestia. As for Gurjaani only three villages are left without gas, In Chiatura, Khulo and Ambrolauri have 6,962; 6,212 and 6,293 potential consumers while in Akhmeta there are only 20 households.

As shown by the analysis, NPV is negative for each municipality and therefore gasification cannot be deemed as a viable project purely from economic and financial standpoint. When calculated based on SOCAR Georgia’s current distribution tariff of 20 Tetri/m3, annual revenue inflows are less than cash outflows (operational and maintenance expenses). Table 8 below shows distribution tariff at which NPV becomes zero for each municipality.

Table 8: Distribution Tariff at Which NPV Becomes Zero

Ninotsminda 1.05 Khashuri 1.46 Bolnisi 0.89

Telavi 5.98 Kareli 2.00

Tsalka 1.09 Kaspi 1.20

As Table 8 shows there are outlier municipalities where gas distribution tariff should equal 43 GEL/m3 (Akhmeta) and 8.64 GEL/m3 (Gurjaani). Best case scenario is Akhaltsikhe Municipality where tariff should increase to 50 Tetri/m3, but even in this case tariff increase constitutes 150% over the current tariff.

Same analysis conducted cumulatively for all 37 municipalities, shows that gas distribution tariff which will make cumulative NPV equal to zero, and the gasification project for all 37 municipalities financially acceptable is 1.265 GEL instead of current 0.2 GEL (constituting a 533% tariff increase).

ANALYSIS OF IMPACTS ON NATURAL GAS DISTRIBUTION TARIFFS FOR DIFFERENT SCENARIOS

Obtaining economic and technical data of high mountainous settlements without access to gas distribution made it possible to analyse different scenarios of impact on the current natural gas tariffs. Likely scenarios were provided by the MoESD, analysis about the impact was prepared by Georgian National Energy and Water Supply Regulatory Commission. Based on methodology of natural gas distribution approved by GNERC as well as “SOCAR Georgia Gas” Ltd and JSC “Saqorggas” tariffs information, it was possible to analyse 4 theoretical scenarios. All 4 scenarios consider transfer/sale of property with different conditions by “SOCAR Georgia Gas” Ltd and JSC “Saqorggas” to the high mountainous settlements. Brief description of each scenario and impact on natural gas distribution tariffs9 is provided below:

Scenario 1: In case “SOCAR Georgia Gas” Ltd and JSC “Saqorggas” were to receive constructed grid free of charge, natural gas distribution tariff would increase by approximately 2 tetri per 1 m3.

Scenario 2: In case “SOCAR Georgia Gas” Ltd and JSC “Saqorggas” were to buy the grid (cost of 558 mil. Lari) natural gas distribution tariff in their licensing area would increase by approximately 14.7 tetri per 1 m3.

Scenario 3: In case “SOCAR Georgia Gas” Ltd and JSC “Saqorggas” were to receive constructed grid with lease (14 mil. Lari per year, 40-year lease) natural gas distribution tariff in their licensing area would increase by approximately 4 tetri per 1 m3.

Scenario 4: In case “SOCAR Georgia Gas” Ltd and JSC “Saqorggas” were to purchase the grid in portions (14 mil. Lari per year, within 40 years) natural gas distribution tariff in their licensing area would increase by approximately 2.4 tetri per 1 m3 for the first year, while increasing by 0.32 tetri per 1 m3 for each of the following years.

4.2 LCCA FINDINGS

USAID Energy Program conducted LCCA for each municipality individually with the purpose of comparing LCC of each alternative to gasification. LCCA showed that in 100% of cases and in both scenarios, biomass-based technologies – biomass boilers and wood stoves are the cheapest alternatives. The tables provided below display summary of LCCA for each cluster. Tables 8 and 9 show LCC per household for each scenario, and Tables 10 and 11 provide total cost of each alternative per cluster.

Table 10: 35-Year LCCA - Scenario 1

As mentioned above costs of alternatives are compared against the cost of gasification. The cells highlighted in green mean that these alternatives have lower LCC, i.e. are more cost efficient than gasification in respective municipalities. Biomass-based technologies are more cost-efficient in 100% of cases. Even such relatively expensive technologies as PV and battery storage proved to be a better option in several instances. Heat pumps, both grid-connected and PV powered also proved to be a cost-efficient option in multiple instances, specifically in 65% of municipalities for grid-connected heat pumps and 57% of municipalities for PV-powered heat pumps in Scenario 1. Numbers are similar in scenario 2, where grid-connected heat pumps are more cost efficient in 65% of municipalities and PV-powered heat pumps in 35% of municipalities.

Tables 10 and 11 below provide summed up LCC of gasification and alternatives for each municipality to help put things in perspective:

5. SUMMARY OF FINDINGS AND RECOMMENDATIONS

The analyses demonstrated that gasification of high-mountainous settlements is not economically viable and is less cost efficient than most of the alternatives assessed in this report. So, one can conclude that purely based on numbers, gasification of high-mountainous villages should not be undertaken. However, based on the partially social nature of the project and the goal of the government to provide access to energy to the Georgian population, it is anticipated that decisions will be made in favour of gasification in several locations. This report provides detailed CBA and LCCA for each subject municipality, and hence presents an opportunity for GoG to minimize losses and optimize its decisions if it decides to go ahead with gasification in some municipalities.

In case GoG decides to proceed with one or several of the alternatives, the LCCA showed that biomass-based technologies: biomass boilers and wood stoves would be the most cost-efficient alternatives followed by heat pumps. However, as already mentioned, wood stoves cannot provide nearly the level of comfort other technologies can, since they cannot be used for central space and water heating. Therefore, biomass boilers are the best alternative in terms of cost and energy efficiency, the level of comfort they can provide and with respect to other important factors like energy security and environment. Yet, biomass has its limitations that must be taken into consideration, the most notable one of them being the availability (or lack thereof) of biomass resources in individual municipalities. USAID Energy Program estimated the volume of biomass that would be required to operate the biomass boilers in all settlements. At current levels of consumption total required annual volume of fuelwood for all clusters would be 124,312 m3, and if we apply an annual 5% consumption escalator, total annual volume of fuelwood consumption would equal 685,707 m3 of firewood by the end of planning horizon.

Based on National Statistics Office of Georgia, total annual firewood production in 2017 was 1.938 million cubic meters of firewood. Considering that estimated escalated annual consumption for 4% of households in Georgia represents 35% of the total existing production, it becomes evident that volume of biomass may not be sufficient to fuel biomass boilers in all subject settlements. Therefore, it is essential that further detailed studies be conducted to realistically assess biomass potential for each region before making the final decision.

USAID Energy Program also recommends conducting a cost-estimation study for CNG virtual pipeline, similar to the study conducted for pipeline natural gas systems by USAID Energy Program.

To summarize, the underlying report provides detailed cost-benefit analysis of gasification, comparative life-cycle cost analysis for several alternatives and equips GoG with the necessary information to make decisions on whether to proceed with pipeline gas construction for high-mountainous villages or opt for alternative solutions.


ANNEX 1: SAMPLE COST-ESTIMATION STUDY FOR PIPELINE GAS Explanatory Notes – Akhalkalaki Municipality

The following estimation has been developed by Ltd “Tsisferi Ali”.

The chart accounts gasification of the villages of Akhalkalaki municipality which are not connected to the gas grid: Gogasheni, Apnia, Karcebi, Azmana, Okami, Erenji, Davnia, Khavati, Miasnikiani, Suldi, Philipovka, Kartsakhi, Buzaveti, Takhcha, Abuli, Modegi, Didi Samsara, Patara Samsara and Dadeshi.

The chart was developed upon assignment by Deloitte Consulting Overseas Projects LLP. The goal of the project is to calculate approximate cost of construction of gasification systems in villages with no access to gas grid, guiding with the presented scheme.

This project is based on the following initial data and materials:

• Situational plans for gas pipelines passing between settlements and through villages.

• Information about number of households in villages that are being studied.

• Construction norms and rules 2.04.08-87*.

• Construction norms and rules 2.04.08.86.

• Norms and rules 01.05-08 “„Building Climatology” approved under the order of the Minister of Economic Development of Georgia 25.08.08 N1-1/1743.

• Different data and references.

The project envisages the use of natural gas for the household and sanitary-hygienic needs of the population, as well as providing gas for heating households and public buildings.

The schemes contain probable gas pipeline networks between source of gas to the territory of the settlements as well as pipeline connections for customers in the villages.

Diameters of pipelines are determined based on hydraulic calculations. Hydraulic calculations are carried out based on estimated hourly gas consumption. Estimated hourly gas consumption for sanitary-hygienic needs of the population were determined according to chart N4 in construction norms and rules 2.04.08-87*.

Estimated hourly gas consumption for heating 1m2 area of a household is determined according to construction norms and rules 2.04.07-86 “Heating Networks” taking into account outdoor air temperature. Outdoor air temperature is used from 01.05.08 “Building Climatology” approved under the order of the Minister of Economic Development of Georgia 25.08.08 N1-1/1743.

The average heating area of residential houses per household was calculated to be equal to 40 m2. Average gas consumption for heating public buildings was calculated using same method as for calculating household consumption, but the average area was 4 m2 per household. Final calculations show that estimated hourly gas consumption per household, considering the need for heating public buildings, is Q=1,28 m3/ hr.

Ltd „Tsisferi Ali“ studied the existing gas pipeline system in Akhalkalaki municipality and concluded that villages of Gogasheni, Apnia, Karcebi, Azmana, Okami, Erenji, Davnia, Khavati, Miasnikiani, Suldi, Philipovka and Kartsakhi can only be supplied with gas from automated gas distribution station with average pressure pipeline in the city of Akhalkalaki. Pipeline that will deliver gas to villages, must be connected to the source of gas near the distribution station. Pressure of gas in the connection point must be 2,0 kg/cm2.

Located in Akhalkalaki municipality, village of Kartikami with an average pressure polyethylene pipeline, with d=90mm is taken as the source of gas for village of Buzaveti. Gas pressure in point of connection is 0,5kg/cm2.

Source of gas for villages of Tachkha and Abuli, was pipeline passing through village of Toria in Akhalkalaki municipality, which is polyethylene d=75mm average pressure pipeline. Pressure in the point of connection is 2,1kg/cm2.

Source of gas for village Modegi, was pipeline passing through Ghado in Akhalkalaki municipality, which is polyethylene d=90mm average pressure pipeline. Pressure in the point of connection is 0,8kg/cm2. Source of gas for villages of Didi samsara and Patara Samsara, was pipeline passing


through village of Merenia in Akhalkalaki municipality, which is polyethylene d=63mm average pressure pipeline. Pressure in the point of connection is 1,2kg/cm2.

Source of gas for village Dadashi, was pipeline passing through Patara Gondrio in Akhalkalaki municipality, which is polyethylene d=75mm average pressure pipeline. Pressure in the point of connection is 1,5kg/cm2.

For supplying gas to the villages from all sources, intervillage average pressure gas pipelines were also considered. Using average pressure gas pipelines, every consumer in the village is supplied with gas. Consumers are supplied with gas from average pressure pipeline using individual small-scale gas pressure regulators. These regulators reduce average pressure to low pressure.

Following chart provides information about gas pipeline needed for interconnections between villages in Akhalkalaki municipality. Gas pipeline is taken account as being fully constructed from PE100 SDR17 polyethylene pipes.
