NTPC Renewable Energy Wins 500 MW in SECI Peak Power Auction at ₹6/kWh

NTPC Renewable Energy Limited announced on August 22 that it secured 500 MW in the Solar Energy Corporation of India’s FDRE-IX assured peak-power auction after the reverse auction concluded August 21, giving the state-owned renewable developer one-third of a 1,500 MW procurement designed to deliver firm renewable electricity during four-hour peak periods. The NTPC Renewable Energy SECI peak power award was secured at a discovered tariff of ₹6 per kWh and adds another large dispatchable-renewable commitment to India’s electricity pipeline.

SECI’s tender seeks 6,000 MWh of assured peak supply, structured as 1,500 MW delivered for four hours from interstate-transmission-system-connected renewable projects with co-located energy storage. NTPC Renewable Energy’s 500 MW award therefore represents approximately 33% of the tender’s contracted power capacity.

NTPC secured 500 MW at ₹6 per kWh

NTPC Renewable Energy, a wholly owned subsidiary of NTPC Green Energy Limited, disclosed the result following the conclusion of SECI’s e-reverse auction.

The company’s exchange filing states that NTPC Renewable Energy SECI peak power capacity totals 500 MW under FDRE-IX and that the discovered tariff for its award is ₹6 per kWh.

The result does not mean 500 MW of generation is already operating. The auction establishes contracted capacity that must progress through project development, contracting, construction, grid connection and commissioning before electricity can be delivered.

SECI is procuring 6,000 MWh of four-hour peak supply

SECI’s official FDRE-IX tender record describes the procurement as assured peak supply of 6,000 MWh, equivalent to 1,500 MW delivered for four hours from ISTS-connected renewable-energy projects.

The tender uses a firm and dispatchable renewable-energy structure rather than purchasing only the instantaneous output of a solar or wind facility. Developers therefore must design generation and storage portfolios capable of meeting specified delivery requirements.

Mercom India reported the auction results on August 22 and confirmed that the procurement involves firm and dispatchable renewable projects with co-located energy storage.

Storage changes the value of renewable generation

Peak-power procurements address one of the central limitations of standalone wind and solar generation: electricity production does not necessarily coincide with the hours when the grid most needs additional supply.

Battery or other eligible storage allows renewable electricity generated earlier to be shifted into contracted peak periods. The four-hour delivery structure also requires materially more energy capacity than batteries designed primarily for short-duration frequency-response services.

The exact generation mix and storage configuration NTPC Renewable Energy will use for its 500 MW award have not been disclosed in the current announcement. The project therefore should not yet be characterized as a specific quantity of solar, wind or battery capacity beyond the contracted peak-supply requirement.

The award expands NTPC’s dispatchable renewable portfolio

NTPC has increasingly participated in Indian tenders that combine renewable generation with energy storage.

In an earlier SECI procurement, NTPC Renewable Energy won 500 MW of solar capacity paired with a required 250 MW/1,000 MWh energy storage system. That December 2024 award illustrates the company’s existing strategy of combining large renewable projects with multi-hour storage.

The new FDRE-IX award differs because the product being procured is assured peak electricity rather than simply solar capacity accompanied by a specified storage installation.

Firm renewable auctions are becoming a larger part of India’s power market

India is adding large volumes of solar and wind generation while electricity demand and evening peak requirements continue to grow. That creates greater demand for resources capable of shifting renewable energy across the day.

Firm and dispatchable renewable-energy contracts can combine generation diversity, storage and operating requirements to provide a more predictable delivery profile than standalone intermittent generation.

For transmission planners and distribution companies, that structure can make new renewable capacity more useful during periods when additional electricity has greater system value. It does not make renewable projects identical to conventional generators, because performance still depends on storage sizing, resource availability and contractual design.

What happens next

NTPC Renewable Energy’s announcement confirms the auction result but does not yet provide the project locations, solar or wind capacities, storage technology, storage MWh capacity, commissioning schedule or final power-purchase-agreement details.

Those disclosures will determine how the developer intends to meet the four-hour peak-delivery obligation and how much new generation and storage infrastructure will ultimately be built.

For now, the verified development is the award itself: 500 MW of contracted capacity at ₹6 per kWh within SECI’s 1,500 MW, four-hour assured peak-power procurement.
