The data points to a deepening mismatch between supply and demand when solar generation floods the grid during the day. Coal power plants can’t reduce output fast enough to make room for surging solar output and the fossil fuel must be kept in operation as it’s needed to meet demand after the sun sets.
The month also saw rare curtailments of wind power, the data showed. This highlights the need to integrate intermittent renewable energy sources with storage, like grid-scale batteries, so that excess electricity can be dispatched in the evening.
India has about 44GW worth of green projects that are struggling to find state utilities to buy their electricity. The government is considering cancelling projects where prospects of an offtake deal look minimal, threatening a goal of doubling clean power capacity to 500GW by the end of the decade.
