The High Court in the Indian state of Andhra Pradesh has given orders to cancel the 6.4 GW mega solar tender announced by the Andhra Pradesh Green Energy Corporation Ltd (APGECL) in November 2020. Further, the state has been asked to issue a fresh tender and cancel the power purchase agreements (PPAs). APGECL had issued this tender to meet the agricultural requirements of the state. However, the request for selection (RFS) and draft of PPA were not made according to the provisions of the Electricity Act 2003.

Thus, Tata Power had appealed to the Andhra Pradesh High Court claiming that the bid documents state that payment-related disputes for the plants will be taken up by the state government mechanisms instead of the electricity regulator, which is not legally tenable.

The results for the 6.4 GW solar auction were announced in February 2021 allocating capacities spread across ten locations in the state. In the auction, Torrent Power emerged as the lowest bidder as it quoted a tariff of Rs 2.47 per kWh for a capacity of 300 MW to be developed at the Kambadur Ultra Mega Solar Park located in Anantapuram district. The auction broke the record for the lowest solar tariff in the state with the previous low being recorded at Rs 2.70 per kWh in 2018.

Among other winners was NTPC Limited which won 600 MW of solar capacity at a tariff of Rs. 2.48 per kWh at the Chakrayapet Ultra Mega Solar Park in YSR Kadapa district. 600 MW at Kambadur Ultra Mega Solar Park in Anantapuram District was won by HES infra at a tariff of Rs 2.49 per kWh. Shirdi Sai Electricals quoted Rs 2.48 per kWh to develop 1.8 GW of projects across four locations in the state. The company also quoted Rs 2.49 per kWh to develop an additional 400 MW project at the Thondur Ultra Mega Solar Park in the YSR Kadapa district. Of the remaining capacity, Adani Green Energy won 2.4 GW of solar projects to be developed in four solar parks in the state at a tariff of Rs 2.49 per kWh. The company also secured 600 MW at a tariff of Rs 2.58 per kWh at the CS Puram Ultra Mega Solar Park in the Prakasam district.
