The inaugural development of public BESS project in Malaysia is part of the Government's efforts to support the energy transition and achieve the goals of increasing the country's installed renewable energy capacity to 70% and to achieve net-zero by 2050.

The Energy rating of 600 MWh of the system will be the dispatchable capacity at COD of the system considering degradation of BESS as provided in RfS, as measured at the Metering Point. Terms and definitions of terminologies related to BESS shall be as defined in IEC 62933- 2-1.

4.1 Selection of BESS Projects for a total capacity of 300 MW x 2 Hours = 600 MWh will be carried out through e-bidding followed by e-Reverse Auction process. The minimum bid size shall be 100 MWh i.e. 50 MW x 2 hours. by MSEDCL. 4.2 Selection of Project Developers will be carried out based on the Contracted Capacity quoted by the Bidders.

The BESSD shall make the BESS available for 1 operational cycles per day, i.e. 1 complete charge-discharge cycles per day. The procurement shall be in power (MW) terms. The BESSD shall install, operate and maintain the BESS to offer facility to MSEDCL to charge and discharge the BESS on an “on demand” basis.

According to the analysis in Sect. 5.1, the most reliable bidding strategy for each BESS at this time is to declare its marginal cost curve as its supply function, so as to determine its own frequency regulation mileage quotation and capacity. Therefore, in this case, the five BESSs take their marginal costs as the declared supply function.
