The Rajasthan Electricity Regulatory Commission (RERC), in a recent order, has ruled that the variable charges determined for the financial year (FY) 2019-20 will be applicable for biomass power projects commissioned during the earlier control periods of FY 2009-2015 and FY 2015-20 and also for FY 2020-21. The same will also apply to FY 2021-22 until there is a change in the fuel cost.
