NTPC, Juniper Green and Sembcorp Win SECI’s 2 GW Wind-Solar Auction

Out of the total 2,000 MW bid capacity, only 900 MW was allotted


NTPC Renewable Energy, Juniper Green Energy, and Green Infra Wind Energy (Sembcorp) were declared winners in Solar Energy Corporation of India’s (SECI) auction to develop 2,000 MW of interstate transmission system (ISTS)-connected wind-solar hybrid power projects (Tranche VII) anywhere in India.

NTPC Renewable Energy quoted the lowest tariff of ₹3.15 (~$0.037)/kWh to win 300 MW. Juniper Green and Green Infra Wind Energy quoted ₹3.21 (~$0.038) to win 150 MW and 450 MW, respectively.

Other participants who submitted their offers but did not qualify include Avaada Energy, who quoted  ₹3.37 (~$0.041)/kWh for 115 MW, and Sprng Energy, who quoted ₹3.55 (~$0.043) for 250 MW.

Out of the total 2,000 MW bid capacity, only 900 MW was allotted.

Aggregate bids received were for only 1,265 MW. The auction capacity was reduced accordingly to 1,012 MW. It was calculated as aggregate bid capacity x 0.8.


SECI floated the tender in October last year.

The projects must be operational within 24 months from the date of the power purchase agreement (PPA).

The rated installed capacity of either component – solar or wind, should be at least 33% of the contracted capacity.

The declared annual capacity utilization factor (CUF) must not fall below 30%.

Developers are obligated to maintain energy supply, ensuring an annual supply equivalent to a CUF not less than 90% and not exceeding 120% of the declared value throughout the 25-year duration of the PPA.

Only wind turbine models listed in the Revised List of Models and Manufacturers and modules registered in the Approved List of Models and Manufacturers issued by the Ministry of New and Renewable Energy are permitted for deployment.

Recently, SECI invited bids to set up 1,500 MW ISTS-connected solar power projects in India under Tranche XIII.

In December, SECI invited bids from scheduled commercial banks or financial institutions for a term loan of ₹10 billion (~$120.24 million) to develop a 300 MW solar power project in the Ramagiri village of Sri Satya Sai District in Andhra Pradesh.
