NHPC’s auction for 1,200 MW ISTS-connected solar power projects with 600 MW/1,200 MWh energy storage systems (ESS) has discovered an L1 tariff of INR 3.09/kWh. This is about 10 percent less than the previous year’s solar + BESS tariff of about INR 3.41/kWh.
Six players – Onix Renewable, Jindal India Renewable Energy, NTPC Renewable Energy, Kolar Solar Power (Rays Power Infra), ReNew Solar Power, and Adani Renewable Energy Holding Nine (Adani Green), have emerged as winners in this auction.
NTPC, Jindal, Kolar and Onix have secured capacities of 300 MW, 180 MW, 150 MW and 100 MW, respectively at the L1 tariff of INR 3.09/kWh.
ReNew and Adani have been awarded 300 MW and 170 MW, respectively at a tariff of INR 3.10/kWh.
The tender for this was issued in September 2024.
Now, PPAs will be signed with the winners for a term of 25 years.
The minimum project size was 50 MW (with a minimum ESS component of 25 MW/50 MWh) and in multiples of 10 MW thereafter under the open category. “The cumulative capacity offered should not exceed 600 MW (with a minimum ESS component of 300 MW/600 MWh) without the greenshoe option and 1200 MW (with a minimum ESS component of 600 MW/1200 MWh) for a bidder with the greenshoe option," noted the tender document.
It further clarified that for projects located in North-Eastern states and special categories, the minimum quantum of contracted capacity that can be offered by a bidder shall be 30 MW (with a minimum ESS component of 15 MW/30 MWh).
The tender document specified that ESS of at least 0.5 MW/1 MWh capacity for 1 MW contracted capacity shall mandatorily be installed as part of the project.
It further clarified that ESS charged using a source other than solar power would not qualify as solar power. “For the avoidance of any doubt, it is hereby clarified that ESS may be owned by the SPG or may be tied up separately with a third party by the SPG, for supply of power,” it added.
Projects are technology-agnostic, permitting the use of crystalline silicon, thin-film, or concentrated photovoltaic modules with or without trackers. No central financial assistance will be provided.
