NHPC’s Other Tenders: A Brief Comparison

With the battery energy storage system (BESS) pricing dropping each year, the tariff rate for projects with the BESS option is also decreasing. For instance, in 2024, SECI awarded its first BESS tender. It awarded the project at the lowest tariff of Rs. 3.41 per unit.

This was the first Solar + BESS tender under BOO mode, which was successfully bid for. Pace won 100 MW with a bid of Rs. 3.41 per unit, JSW Neo Energy won 500 MW with a bid of Rs. 3.42, followed by Acme Solar with a 350 MW win, and Hero Solar with 250 MW, also at Rs. 3.42. For JSW Energy, the win added significantly to their green storage portfolio.

NHPC FDRE Project

The tariff for NHPC’s solar plus storage tender, Rs. 3.09/kWh, is relatively lower than that for its FDRE tender. Last year, SECI awarded its 1.2 GW FDRE project under Tranche II to five successful bidders: Essar Renewables, Juniper Green Energy, Serentica Renewables, Hexa Climate Solutions, and Avaada Energy. The tariff for this tender was as low as Rs. 4.37 per kWh, which is higher than that for the latest solar plus storage tender.
