Grid-India flags complex voltage swings in solar zones

As India still lacks large-scale RE storage, managing infirm RE sources becomes difficult when they are fed into the grid.

Senior executives at Grid-India said they are looking at a two-pronged approach.

"One is that we run thermal power in two shifts — first during the morning hours, then take it offline during solar hours, and then sync it again just before sunset. The other is to run thermal power at a heat rate of 40–55 per cent and then ramp it up whenever RE supply falls during the daytime and for night hours," said an executive.

Grid-India is the electricity grid operator of the country.

The executive added that CERC is expected to introduce regulations that would provide compensation to thermal power generators for reducing their heat rate.
