Wind and solar paired with batteries, locked in for 25 years
In the long arc of India's energy transition, a single contract can mark a turning point — not because of its size alone, but because of what it represents. On February 19, 2026, ACME Solar's subsidiary committed to a 25-year agreement with state utility SECI to deliver 190 megawatts of hybrid wind-solar power at a fixed tariff, binding two institutions to a shared energy future stretching to 2053. The deal reflects a maturing renewable market where long-term certainty, technological integration, and institutional trust are becoming the true currencies of progress.
- India's renewable buildout is accelerating fast enough that a single company — ACME Solar — has signed 1,240 MW of new contracts in a single fiscal year, signaling a market running at full stride.
- The hybrid design of this project — wind, solar, and battery storage working in concert — is a direct answer to the oldest criticism of renewables: that they cannot be relied upon when demand peaks.
- Performance obligations are unusually strict, requiring 80% peak-hour delivery and a 50% annual capacity utilization factor, leaving ACME little margin for engineering or logistical missteps before the February 2028 deadline.
- Financing from Power Finance Corporation and regulatory clearance from the Central Electricity Regulatory Commission have already been secured, removing two of the largest obstacles that typically delay infrastructure projects of this scale.
- A parallel 220 MW solar-plus-storage win in Madhya Pradesh, disclosed the same day at a lower tariff, suggests ACME is simultaneously competing across multiple market segments and geographies.
- With 5,820 MW in signed agreements and over 5,100 MW under construction, ACME is no longer a growth story in waiting — execution capacity is now the defining test.
On February 19, 2026, ACME Solar's subsidiary ACME Urja One Private Limited signed a 25-year power purchase agreement with SECI Limited, India's state-owned renewable energy utility, to build and operate a 190-megawatt hybrid power plant at a fixed tariff of Rs. 4.72 per unit. Commercial operation is targeted for February 27, 2028.
The plant pairs wind turbines and solar panels with battery storage — a configuration designed to overcome the variability inherent in renewable generation. The battery system stores energy during periods of high generation and releases it during peak demand, allowing the project to meet a demanding obligation: supplying 80% of peak power requirements during peak hours and maintaining a 50% annual capacity utilization factor. SECI receives reliable power; ACME secures a long-term revenue stream backed by a AAA-rated counterparty.
The financial and regulatory groundwork is already laid. Power Finance Corporation has committed project financing, the Central Electricity Regulatory Commission has approved the tariff, and state regulators have cleared the procurement plan. The 190 MW project is the first phase of a broader 380 MW development, leaving room for expansion once the initial phase is proven.
The contract brings ACME's total signed portfolio to 5,820 MW and its fiscal-year signings to 1,240 MW — a pace that reflects both the company's growing execution capacity and India's intensifying appetite for renewable infrastructure. Roughly 2,966 MW is already operational, with another 5,105 MW under construction and approximately 17 gigawatt-hours of battery storage across the portfolio.
The same day, ACME disclosed a separate 220 MW solar-plus-storage win in Madhya Pradesh's Morena Solar Park at a lower tariff of Rs. 2.764 per unit, with a December 2027 commercial operation date — underscoring a company actively competing across multiple project types and regions simultaneously.
The February 2028 deadline for the SECI project is firm, and the technical requirements are exacting. Grid connections, equipment procurement, and workforce deployment all carry real execution risk. But with financing secured, approvals in place, and a government entity as the buyer, the foundation for delivery is as solid as the renewable sector can currently offer.
ACME Solar Holdings moved deeper into India's renewable energy infrastructure on February 19, 2026, when its subsidiary ACME Urja One Private Limited signed a quarter-century contract to build and operate a 190-megawatt hybrid power plant. The deal with SECI Limited, a state-owned utility rated AAA by credit agencies, locks in a price of Rs. 4.72 per unit of electricity and commits the company to delivering power for 25 years starting February 27, 2028.
The project itself represents a particular kind of modern power infrastructure: wind turbines and solar panels working in tandem, paired with battery storage systems designed to smooth out the natural variability of renewable generation. This hybrid approach allows the plant to meet a demanding daily obligation—supplying 80 percent of peak power requirements during peak hours—while maintaining a minimum annual capacity utilization factor of 50 percent. The battery system gives the plant the ability to store energy when the sun shines or wind blows, then release it when demand peaks. SECI, the buyer, gets assured power delivery; ACME gets a long-term revenue stream.
The financial backing is already in place. Power Finance Corporation, a government lending institution, has committed financing for the project as part of its Phase II development plan. The tariff structure has cleared the Central Electricity Regulatory Commission, and state regulators have approved the procurement plan. The project is the first phase of a larger 380-megawatt development, suggesting ACME sees room to expand the footprint once this initial phase proves viable.
This single contract adds meaningful scale to ACME Solar's portfolio. The company now has 5,820 megawatts of signed power purchase agreements across its business. In the current financial year alone—which runs through March 2026—the company has signed 1,240 megawatts of new contracts. That pace of growth reflects both the company's execution capability and the broader Indian appetite for renewable energy capacity. The company operates across solar, wind, hybrid systems, and battery storage, with roughly 2,966 megawatts already operational and another 5,105 megawatts under construction. The battery storage component is substantial: approximately 17 gigawatt-hours of capacity across the portfolio.
The deal also signals something about how India's renewable energy market is maturing. A quarter-century contract with a state utility at a fixed price represents the kind of stable, long-term business model that attracts institutional capital and allows companies to plan multi-year construction and operations schedules. The performance metrics—the 50 percent capacity factor, the 80 percent peak obligation, the 95 percent availability requirement—are specific and measurable, leaving little room for ambiguity about what success looks like.
ACME Solar disclosed the agreement under India's securities regulations, filing it as a material event on February 19. The company also noted separately that it had won a 220-megawatt solar project with battery storage in Madhya Pradesh's Morena Solar Park, at a lower tariff of Rs. 2.764 per unit, with a commercial operation date of December 31, 2027. That project requires the company to deliver four hours of peak power daily—two hours in the morning, two in the evening—with the morning energy supplied free by the procurer and the evening energy charged from the solar plant itself.
Taken together, these contracts show a company in expansion mode, locking in long-term revenue while building out the operational and engineering capacity to deliver. The February 2028 deadline for the SECI project is firm, and the technical requirements are exacting. Execution risk remains real—grid connections must be secured, equipment must be sourced and installed, teams must be trained and deployed. But the financial foundation is set, the regulatory approvals are in place, and the buyer is a government entity with the resources and incentive to see the project through.

The Hearth Conversation Another angle on the story
Why does a 190-megawatt contract matter enough to announce it separately? Isn't this just one project among many?
Because it's a 25-year contract with a government utility at a locked-in price. That's not a one-off sale—it's a revenue stream that lets the company plan, borrow money, and commit resources with confidence. One project alone might not move the needle, but 1,240 megawatts signed in a single year tells you the company is winning consistently.
The tariff is Rs. 4.72 per unit. Is that good or bad?
It's competitive enough that SECI chose it in what was presumably a bidding process. The company also won a solar project at Rs. 2.764 per unit in the same region. Both prices suggest the market is tight and margins are thin, but the volume compensates. ACME is betting on scale and operational efficiency.
What's the actual risk here? The project doesn't start until 2028.
Two years is a long time in construction. Grid connections have to be built, equipment has to be sourced—and global supply chains for solar and wind components are still volatile. The battery storage piece adds complexity. If costs rise or timelines slip, the fixed tariff becomes a problem. ACME has to hit those performance metrics—50 percent capacity factor, 80 percent daily peak obligation—or face penalties.
Why does SECI care about 80 percent peak power obligation? Why not just buy whatever power is available?
Because peak hours are when demand is highest and prices are highest. A utility needs reliable power when people are actually using electricity. A hybrid plant with batteries can promise that. It's worth paying for certainty.
What does this say about India's energy future?
That the country is serious about moving away from coal and toward renewables, and it's willing to sign long-term contracts to make it happen. ACME's portfolio of 5,820 megawatts is just one company. Multiply that across dozens of developers and you're looking at a real energy transition.
