INR 5.99/kWh is the new fixed-price benchmark for four-hour assured peak renewable power in India, discovered in SECI’s 1,500 MW FDRE-IX tender and equivalent to $0.068/kWh.
Waaree Energies took 700 MW at that lowest tariff. NTPC Renewable Energy Ltd. and ACME Solar cleared at INR 6.00/kWh, with 500 MW and 300 MW respectively. The split matters less than the structure: these are fixed-price obligations to deliver firm power during peak demand hours, not plain-vanilla solar output.
The tariff is the revenue line; the missing half is the developer's all-in cost of capital and storage capex. The tender announcement does not identify the technology mix, contract tenor, performance security terms, offtaker credit support, payment security, penalty mechanics, or bidder cost data.
On the reported numbers, the peak product cleared INR 0.74/kWh above SECI’s recent renewable energy round-the-clock tariff of INR 5.25/kWh. That gap is a rough, disclosed-number proxy for what a four-hour peak assurance product costs relative to round-the-clock renewable supply, though the two tenders are not identical. It is not a margin.
Waaree’s one-paisa advantage over NTPC REL and ACME Solar gave it the largest allocation: 700 MW at INR 5.99/kWh, against 500 MW and 300 MW at INR 6.00/kWh. The lowest tariff may signal a cost advantage or more aggressive equipment and financing assumptions.
The return question for every bidder is whether a fixed revenue stream at INR 5.99–6.00/kWh can cover capital, debt service, operations, and the cost of guaranteeing peak dispatch over the term of any signed agreement.
The next marker is whether these tariffs convert into signed power supply agreements and financed projects. A separate test is whether the storage costs implied by four-hour peak delivery stay below the INR 6/kWh revenue line once project details surface.
