A government-appointed panel has recommended that coal-fired power plants be given incentives to install equipment to raise or reduce generation at short notice to accommodate renewable power and that supply from sources such as solar and wind may need to be cut 1% to balance the grid.
Renewable power fluctuates as sunshine and wind speed vary, which puts pressure on the grid. This requires thermal plants to adjust their supply to keep the grid stable. The committee, headed by a member of the Central Electricity Authority (CEA), said in a report that reducing or raising thermal supply is costly and takes hours. Hence, additional investment is needed to make these plants flexible.
The committee was asked to forecast future generation scenario and estimate extent of flexibility required in the system on account of demand as well as variation in renewable energy supply. Read More
