Andhra Pradesh throttles wind generation after court orders

After getting a rap from the court that stayed the tariff renegotiation order issued by the newly-elected state government, the state administration resorted to curtailing wind and solar power generation.

On the same day as the court ruling, the Andhra Pradesh government verbally informed all wind power developers to stop production.

The curtailment was in response to the request from the regional grid operator to reduce generation, but the standard practice is to back down thermal generation as renewable energy generators are given a "must run" status under the grid code.

Renewable energy operators claimed in the first two days of curtailment they have lost over 50GWh of wind and solar generation and there is no way to recoup these losses.

The developers petitioned the courts and approached the Ministry of New and Renewable Energy (MNRE) to direct the state government to stop the curtailment.

The MNRE sent a letter to all states directing them to stop renewables curtailment citing the relevant provisions of the electricity grid and the electricity act 2003.

In a new order, the high court of the state observed that the state cannot unilaterally curtail renewable energy as the matter of tariff negotiations is under consideration and scheduled for next hearing on 22 August.

The court also reaffirmed the "must run" status and has asked the government to provide justification for curtailment.

The stand-off between the state and the operators have put nearly 5.2GW of pipeline renewables capacity, including nearly 3.9GW of wind, under threat.
