Andhra Pradesh curtails wind power; violates grid norms again

Andhra Pradesh on Friday regulated electricity supply from wind power plants during peak hours for second day in row in gross violation of regulatory norms, which might escalate its ongoing legal spat with the renewable energy companies in the high court.

Sources said the curtailment was undertaken by the state without attributing any valid reason and even as there was no abnormality in frequency of national grid on Friday. But the state decided to ramp up its thermal generation and disconnect renewable plants causing them losses. On Thursday, the state backed down about 3000-mw of solar and wind capacity which across the country enjoys ‘must-run’ status.
