1. Background and Context

AEPC made a decision to update reference prices for the domestic and household based

renewable energy technologies (RETs) for the FY B.S. 2078/79. The decision was based on the

provision under clause 12.5 of Renewable Energy Subsidy Policy (RES), B.S 20731. For the

work, AEPC hired a consulting firm to recommend the Reference Prices (RP) of the RETs for

the current FY.

As per the guidance from AEPC and Term of Reference (ToR), the main task of the consultant

was to collect information on existing reference prices for all the household and institutional

renewable energy technologies promoted by AEPC, review and recommend reference prices for

the FY B.S. 2078/79. Several rounds of meeting among consultant and officials from AEPC

were organized in AEPC regarding way forward to determine the reference prices for the FY

B.S. 2078/79. An approach to set the RP was agreed between the AEPC and consultant.

As per the RES 2073, subsidy for domestic or households (HHs) systems will be implemented

by demand driven model through recognized competent company or firm where the

procurement of goods and services will be done by the end users or HHs themselves. For this

purpose, AEPC prepares list of recognized competent company or firm in the beginning of each

fiscal year. Recognized competent company or firm will be eligible for promotion and

implementation of the RETs. The listed recognized competent companies or firms will be

responsible for design, supply, installation, testing and after sales service support of RETs as

per RES 2073 and RE subsidy delivery mechanism, 2073. In order to assure the quality and

best services to the end users, it is necessary to standardize prices of the technologies to be

served for the intended end users. To fulfill objective, this analysis has aimed to update and

standardize reference prices of the technologies for the current Fiscal Year B.S. 2078/79.

Following eleven (11) different kinds of RETs are considered to set reference prices for this

fiscal year.

1. Solar Home Systems (SHS)

2. Institutional Solar Power Systems (ISPS)

1RE Subsidy Policy Clause 12.5:In case of domestic renewable energy technologies particularly solar home systems,

biogas, metallic improved cook stoves, metallic rocket stove, etc., per unit cost price will be determined for the suppliers every fiscal year depending upon demand of district and geographic region. Users will receive subsidy from recognized company on the basis of the determined per unit cost price. However, such subsidy will not exceed the amount as mentioned in respective technology-specific clauses of this policy.

6. Solar Cooker (SC)

7. Biogas Systems (BS)

8. Improved Water Mill (IWM)

9. Institutional Improved Cook Stove (IICS)

10. Metallic Improved Cook Stove (MICS)

11. Rocket Stoves (RS)/Natural Draft Stoves/ Forced Draft Stoves

It is also agreed that the consultant would compile the final report and incorporate received

inputs from AEPC for producing final report.

2. Objectives The main objective of the task is to review prices of RETs based on principles provisioned under

RE subsidy delivery mechanism (SDM) and provide recommendations of reference prices for

the fiscal year B.S. 2078/79 to AEPC.

3. Scope of Work

The committee detailed down scope of task into following specific activities.

• To review RETs currently promoted by AEPC

• To analyze, review and update the reference prices of the RETs

• To prepare, analyze, and validate reference prices of various technologies

• To prepare and submit the draft report to AEPC Management

• To incorporate comments and feedback from AEPC Management, and finalize the report

4. Methodology In this section, the detailed methodology and approaches undertaken during revision and

preparation of reference pricing of renewable energy technologies (RETs) has been elaborated.

According to Renewable Energy Subsidy Policy and Subsidy Delivery Mechanism B.S. 2073,

there are five (5) parameters that are considered for the estimation of reference prices of

household or domestic RETs that are: local market rate with expert analysis, international

market rate, association rate, last fiscal year rate and other government rate (tender rate). In

general the prices of all the RETs were estimated from all of the above five sources and those

prices are multiplied by the weight-age factors considered as follows.

6

S. N. Parameters Weight-age Factors

1 Local market rate expert analysis 0.1

2 International market rate 0.1

3 Association rate 0.1

4 Last fiscal year rate 0.4

5 Other government rate (tender rate) 0.3

Reference Price (RP)= Local market rate*0.1+ International market rate*0.1+ Association

rate*0.1+ Last fiscal year rate*0.4+Other government rate*0.3

The basis for weight factors of above five parameters are taken from the last year reference

pricing approach. The prices for the five parameters used in the calculations are considered in

the following ways:

• To those technologies of which the local market prices are available at present, the price

was collected from the local suppliers with the support of AEPC. The local market prices are

analyzed by technical experts and accordingly reference prices are calculated using weight-

age factors.

• The International market rates have been considered as per the approaches undertaken in

the last fiscal year.

• Association rates have been considered as per the approaches undertaken in the last fiscal

year.

• Last year (FY 2077/78) reference price/MRP rates have been considered under the Last

Fiscal Year rates.

• Other government rate (tender rate) is taken from the actual implemented system price in

the last fiscal year.

• The consultant has revised reference prices and RETs standards by incorporating inputs

and comments received from AEPC Management/officials.

7

5. Limitations

Following are the limitations of updating reference prices that are drafted for the FY 2078/79.

1. The current market price of RETs is based on the system price received from

stakeholders of respective technologies.

2. The expert evaluation is considered from the previous year reference pricing, data

provided by the local suppliers and consultation with the corresponding component head

for the actual billed rate of last fiscal year 2077/78.

3. Filed verification of the actual cost could not be done due to COVID -19 pandemic and

transportation restrictions due to lockdown.

4. All reference prices are estimated following the last year’s technical specification that

has been used by AEPC.

6. Reference Price Results and Discussion

The reference pricing of RETs mainly Solar Technologies, Biogas Technologies, Cook Stove

Technologies and Improved Water Mill Technologies have been revised on the basis of various

factors including reference from last fiscal year 2077/78 (association price, international market

price and last year reference prices), other government rate (actual price of implemented

technologies in the fiscal year 2077/78) and present market price of the technologies. The price

has been estimated for all three geographical locations categorized in the renewable energy

subsidy policy and delivery mechanism. The districts and rural municipalities under the

geographical category A, B, C, based on RES description, are presented in the Annex-1.

The following reference prices (RP) are recommended by the consultant for the FY B.S.

20778/79.

6.1 Solar Home Systems (SHS)

There are 10Wp, 20Wp, 50Wp, 55Wp, 60Wp, 80Wp and 100Wp standard size solar home

systems that lie under demand and are commonly available for serving under subsidy scheme.

The technical standards of the item components used for SHSs shall be tested and certified by

RETS Nepal in order to comply NIPQA standards. The proposed reference price of SHSs for

the FY 2078/79 is as follows:

RP for Institutional Solar Power Systems (ISPS)

The above reference price relates to the technical standards considered in the previous fiscal

year 1000kWp and 2000kWp ISPS packages. However, the reference price of the enhancement

on technical standards such as Maximum Power Point Tracker (MPPT) solar charge controller,

Inverter with IEC certificate, enhanced earthling and protection systems and Valve Regulated

Lead Acid Batteries (VRLA)/GEL batteries could be higher and demands additional work to

determine RP.

The above tabulated proposed RP of ISPSis compared with the last fiscal year FY 2077/78 RP

and deviations are listed in the Table below.

6.3 Solar Irrigation Pumping System (SIPS)

In the reference prices of last fiscal year 2076/77there were35 sets of standard SIPS packages

of 10 meter, 20 meter, 30 meter, 50 meter, 70 meter, 100 meter and 200 meter pumping heads

with respect to minimum daily pumping capacity of 10kL, 25kL, 50kL, 100kL and 400kL. AEPC

experienced that the solar irrigation pumping system of 5 meter and 15 meter heads are also

being demanded by end users, especially in the Tarai region where pumping heads are short

due to existence of shallow water table. Hence, from last FY, AEPC had decided to include 5

meter and 15 meter pumping heads as additional system packages. Likewise, more options of

water discharges are included since last fiscal years’ reference prices, those are 200KL and

300KL discharge per day. Hence all together there are 63 numbers of SIPS packages as

proposed in last FY, is also taken in the reference pricing report for current FY 2078/79.

Following factors or parameters are considered while estimating reference price for solar

irrigation pumping system (SIPS).

a) From current FY, the RP of each package has been divided into electro- mechanical and

civil subdivisions.

b) To those combinations of pumping head and flow of which there was no demand or no

actual billed price in the previous fiscal year, the last year rates have been referred.

c) To those SIPS packages of which previous year approved rate was available, same rate

was referred under the Government rate or actual amount of last year. To those districts of

which no SIPS demands existed in previous year, the same ratio of increment or decrement

has been considered under government tender rate.

d) The transportation charges for all the SIPS packages are considered same amount as

previous fiscal year.

The proposed reference prices of solar irrigation pumping systems for the FY 2078/79 are as

follows with deviation/changes form last FY 2077/78.

6.7 Domestic Biogas System

As per financial act 2077/78, Government of Nepal has declared that, an additional VAT be

levied for this fiscal year 2077/78 on equipment that shall be imported for biogas purpose. An

analysis has been done for the equipment under VAT, and it has been determined that an

average of 15% of the total project cost is liable for 13% VAT. Hence the reference price has

been adjusted taking into account the additional VAT cost that shall be imposed for the

imported materials used in domestic biogas. The reference price of different plants considering

unskilled labor and local materials for Terai, Hill and Mountain regions of the country are

tabulated below.

6.13 Improved Water Mill (IWM)

AEPC is providing subsidy on two different type of IWM known as short shaft and long shaft

they are distinct on the basics of their functions. Replacement of wooden parts (rotor and shaft)

with metallic parts is the main improvement made in this technology. Subsidy amount facilitates

end user via private sector for the promotion and installation of IWM in remote areas where

there is no other types of facilities avails for grinding purposes. This really helps in alleviating

drudgery of women and children of that area. Short shaft solely for grinding, and long shaft for

grinding and other end uses such as paddy hulling and husking, rice polishing, saw-milling, oil

expelling, lokta beating, chiura (flattened rice) making, and a number of others as per the need.

The compiled rate received from manufacturers and suppliers came somewhat more than double

than last fiscal year's reference price. The subsidy amount for IWM is fixed as per policy and the

reference rate fixed in last fiscal year is way above than the subsidy amount, hence the

committee agreed to have reference prices as provided in the tables below for this fiscal year

2078/79 along with changes prices form last FY- 2077/78:

The amount of water to be used during WBT testing shall be determined based on the burning

capacity of the stove provided by the manufacturer/designer.

In case the manufacturer is unable to provide the burning capacity of stoves, the following

process shall be used to calculate the burning capacity of the stove.

Steps for calculating the burning capacity of the stove

I. Weight one bundle of fuel (approximately 2 kg). Let the mass be M1 kg.

II. Stack the fuel in a honey comb fashion in combustion chamber up to 3/4 of the height for

continuous feeding type cookstove, or in a pattern recommended by the manufacturer.

III. Put the pot on the stove as recommended by the manufacturer with 10 liters of water.

IV. Sprinkle 10 to 15 ml of kerosene on the fuel from the top of the cookstove and ignite the

fire.

V. After half an hour of burning the fuel, weigh the remaining fuel and let the mass be M2

kg.

VI. Calculate the burning capacity of the cookstove as heat input per hour as follows:-

Burning capacity rating = 2 (M1 – M2) kg/hr Heat input per hour = 2 (M1 – M2) × CV kcal/hr or 2 (M1 – M2) × CV × 0.001163 kW Where, M1 = the initial mass of the cookstove with test fuel in kg, M2 = the mass of the cookstove with fuel residues, after burning the test fuel for half an hour in kg, and CV = Calorific value of the test fuel in kcal/kg.

Selection of the vessel and mass of water for testing

The size of the vessel shall be selected as per the design recommended by manufacturer (or

vessel provided by manufacture). If the manufacturer has not provided details of the vessel, an

appropriate vessel size for testing shall be determined by the test station based on the mass of

water for testing. To minimize retention of heat by pot, mass of vessel shall be kept as low as

possible and the specification of the vessel used for testing shall be reported in the certificate.

The mass of water to be taken for the test shall be selected from the Table as shown below.

Note: While selecting the size of the vessel, the volume of water should not exceed 70% of the total volume of the vessel.
