ACME Solar Enters Agreement With SECI For 300MW Wind-Solar Hybrid Project

Market snapshot: ACME Solar Holdings Limited has executed a long-term Power Purchase Agreement with Solar Energy Corporation of India Limited for a 300 MW interstate transmission system-connected Wind-Solar Hybrid Renewable Energy Project. The 25-year agreement, signed through the company's wholly owned subsidiary ACME Renewtech Fifth Private Limited, secures a fixed contract tariff of ₹3.25 per unit approved by central and state regulators.

Data Snapshot

• Power Purchase Agreement executed for a 300 MW ISTS-connected wind-solar hybrid project.
• Electricity will be supplied to SECI at a fixed approved tariff rate of ₹3.25 per unit.
• The contract carries a tenure of 25 years with power supply set to commence on June 30, 2028.
• Total PPA-signed portfolio expands to 6,870 MW, representing approximately 85.13% of the total 8,070 MW contracted capacity.

What's Changed

• Execution of this 300 MW PPA increases ACME Solar's active PPA-signed capacity by ≈4.57% (derived: 300 MW added to the previous 6,570 MW portfolio).
• Secured tariff of ₹3.25 per unit provides fixed long-term pricing, compared to previous project levels such as the ₹3.05 per unit rate obtained for its Sikar solar project in 2025.
• Operational contracted portfolio stands solid at 2,990 MW, while the under-construction PPA-signed pipeline has scaled to 3,880 MW.

Key Takeaways

• Strong Revenue Predictability: The 25-year PPA tenure at a fixed rate of ₹3.25 per unit guarantees reliable long-term cash flow predictability, backed by SECI's excellent payment track record.
• Optimized Grid Usage: The hybrid project will utilize the company's already secured transmission connectivity at high-irradiation and wind resource zones, minimizing grid congestion risks and capital expenditure.
• Robust Portfolio Growth: The deal accelerates progress toward ACME Solar's strategic roadmap of achieving 10 GW of operational contracted capacity by 2030.
• High Operational Commitment: The project carries a minimum annual Capacity Utilisation Factor commitment of 30%, highlighting the utility of wind-solar hybrid systems in maintaining stable energy dispatch.

SAHI Perspective

This agreement demonstrates ACME Solar's disciplined expansion in the higher-margin hybrid renewable energy segment. By combining solar and wind resources, the company is positioning itself to mitigate generation volatility. Securing a fixed tariff of ₹3.25 per unit from a AAA-rated offtaker like SECI significantly reduces payment counterparty risks and reinforces the bankability of ACME's under-construction portfolio, which now stands at 5,080 MW.

Market Implications

The successful lock-in of this PPA is a highly positive signal for the market, indicating that public utility tenders continue to offer strong tariffs that support sustainable project economics. This also boosts investor confidence following ACME's recent capital raises, confirming that the company is quickly deploying capital to construct its high-irradiation and wind-zone pipeline.

Trading Signals

Market Bias: Bullish

The execution of this 300 MW SECI PPA provides long-term cash flow predictability and enhances the company's active under-construction PPA-signed pipeline to 3,880 MW, supporting strong forward revenue growth.

Overweight: Renewable Energy, Utilities, Power Infrastructure

Trigger Factors:

• Successful grid integration and commissioning of the hybrid project before the Scheduled Commencement of Supply Date on June 30, 2028.
• Achievement of the mandatory 30% minimum annual Capacity Utilisation Factor (CUF).
• Progression and commissioning of the remaining under-construction contracted portfolio of 5,080 MW.

Time Horizon: Medium-term (3-12 months)

Industry Context

India's renewable energy sector is transitioning rapidly from plain-vanilla solar towards complex multi-technology and hybrid projects. Integrating wind and solar generation is vital for grid stability, which is why central offtakers like SECI are increasingly favoring hybrid and storage-backed tenders. The fixed tariff of ₹3.25 per unit under SECI's Hybrid Tranche IX is highly competitive, ensuring robust utility participation while protecting developer margins against the backdrop of fluctuating global module prices.

Key Risks to Watch

• Project Execution and Commissioning: Delays in the construction and synchronization of the wind and solar components before the June 30, 2028 deadline could attract penalty clauses or tariff adjustments.
• Resource Volatility: Since hybrid projects rely on complementary solar radiation and wind speeds, any multi-year variations in resource availability could challenge the company's ability to maintain the contractually mandated 30% minimum annual Capacity Utilisation Factor.
• Transmission Infrastructure: Timely availability and stability of the interstate transmission system (ISTS) substations are critical to evacuating power without curtailment.

Recent Developments

ACME Solar has recently demonstrated strong operational progress. On July 15, 2026, the company successfully commissioned 110.336 MWh of Battery Energy Storage System (BESS) capacity in Jaisalmer, Rajasthan. Additionally, on June 5, 2026, ACME Solar concluded its first post-listing capital raise by successfully completing a ₹2,800 crore Qualified Institutional Placement (QIP) with massive institutional participation. For the full year FY26, the company reported a massive 98.5% year-on-year increase in Consolidated PAT to ₹498 crore on a total revenue of ₹2,507 crore.

Closing Insight

The execution of this 300 MW hybrid agreement highlights ACME Solar's capability to lock in premium utility-scale PPAs. By leveraging secured transmission assets and diversified technology, the company continues to establish itself as a primary beneficiary of India's grid-decarbonization wave.
