Facts : Teega Mixed Development is ELIGIBLE for ETOU. (Off-Peak RM0.281 per kWh, Mid-Peak RM0.357 per kWh & Peak RM0.584) Questions : But how much can we save?

WHAT IS ETOU? Extended Time of Use

Current Flat Rate for Teega : C1 (Perdagangan/Commercial)Usage : RM0.365 per kWhMD : RM30.30 per KWCLC : RM8.50 per KW

PF : 1.5% surcharge of the current bill – for every 0.01 less than 0.85 power factor.3% surcharge of the current bill – for every 0.01 less than 0.75 power factor

MOVING FORWARD ONCE ETOU IS ADOPTED

Step 1 : To understand the consumption profile and work to move the usage out from the peak hours(red) to mid-peak(orange) & mid-peak(orange) to off-peak(green).

Step 2 : Update the timers accordingly for the lightings and pumps. (Bahar & Technicians)

11

TO REDUCE THE USAGE (kWh)

Step 3 : It is crucial to start changing all the CFL bulbs (18W) to LED bulbs(9W) with the same LUX brightness. #RM15 per LED bulb(9W, 4500K, 15000hrs) is an estimation for Philips bulb from LAZADA. ROI to convert all LED bulbs is 5.5months.

Step 4 : Another possible savings is to implement the OFF timing for Common Lightings (40%) and maintain the Essential Lightings (60%) from 12.00am to 6.00am.

TO REDUCE MAX DEMAND SURCHARGE

Maximum demand (MD) is the highest level of electricity demand recorded by TNB meter during a 30-minute interval in a month. Tariff : RM30.30 per KW

Proposal : - To distribute power usage evenly and to reduce concentration on certain hours.- To obtain devices to measure/monitor the consumption on-line.

CLC CONCERN (4th to 6th YEAR). CURRENT 3rd YEAR

Concern : Entering into 4th year, it is estimated to have an increase of >150% for the CLC charges. No CLC surcharge on 7th year onwards.

Taking Oct-18’s(3rd year) bill as reference, the total CLC amount is RM3,564.73.Assuming the Max Demand captured is the same for the month of Oct-19 (4th year), the amount shall be RM9,382.15 (163%)

CLC CONCERN (4th to 6th YEAR). CURRENT 3rd YEAR

Needs to start saving before entering to the 4th year for the CLC surcharges..

To check with developer / consultant if the declared Max Demand can be altered. With the past 1.5 years data, we should be able to provide a more accurate Max Demand.

CLC charges shall not apply if the Max Demand captured/recorded is higher than 75% of the Declared Max Demand. For eg, to reduce the Declared Max Demand for Suites to 200kW, and 75% shall be 150kW. With proper control and monitoring, as long Max Demand captured is more than 150kW, CLC surcharge shall be waived.
