What is a bessd & how does it work?

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.

What is the most reliable bidding strategy for a Bess?

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.

Is a 600 MWp solar plant being built in Congo?

Sun Plus, a unit of The Sandi Group (TSG), has launched construction work on a 600-MWp solar plant in the Democratic Republic of Congo that is part of an even larger project totalling 1 GWp.
