India recorded 68 major disturbances in renewable energy sector complexes between January 2022 and June 2025, with generation losses ranging from 1gigawatt (GW) to 7 GW in individual events, highlighting the growing grid management challenges as renewable energy capacity expands, according to a top government official.

The incidents occurred mainly at the interstate level in renewable energy complexes in Rajasthan and Gujarat and were linked to some generators not meeting low voltage ride through (LVRT) and high voltage ride through (HVRT) requirements, Jishnu Barua, Chairperson, Central Electricity Regulatory Commission, said. Enforcement measures have since reduced the frequency and scale of such incidents.

“Between January 2022 and June 2025, we saw 68 grid disturbances in renewable energy complexes, with generation losses ranging from 1,000 MW to 7,000 MW. Most of these incidents occurred in Rajasthan and Gujarat and were linked to non-compliance with LVRT and HVRT requirements,” said Barua, at the 7th CII International Energy Conference, adding that enforcement measures had since reduced the frequency and scale of such incidents.

The growing share of variable renewable generation makes grid management more complex. Solar and wind output can change rapidly depending on weather conditions, creating sudden changes in electricity supply. Barua said this requires higher balancing reserves, more flexible operation of thermal plants and advanced forecasting. Sudden fluctuations in renewable output can also affect system frequency and require intervention to maintain grid security.
