ACME Solar Completes 53.63 MW BESS Phase-III Reaching 159.58 MW Total Capacity

Market snapshot: ACME Solar Holdings Limited has successfully commissioned Phase-III of the Battery Energy Storage System component of its Firm and Dispatchable Renewable Energy project in Rajasthan. Executed through its wholly owned subsidiary, ACME Greentech Seventh Private Limited, this expansion adds 53.63 MW of discharge capacity and 214.52 MWh of energy storage to the company's active operational portfolio.

Data Snapshot

• The newly operationalized Phase-III BESS unit delivers 53.63 MW of discharge capacity and 214.52 MWh of energy storage in Bikaner, Rajasthan.
• Cumulative commissioned BESS capacity for the subsidiary ACME Greentech Seventh Private Limited reached 159.58 MW and 638.32 MWh.
• The total planned BESS discharge capacity for this specific Bikaner FDRE project is 300 MW and 1,200 MWh.
• ACME Solar's Q1 FY27 consolidated net profit surged 79.9% YoY to ₹235.3 crore, supported by revenue of ₹857.5 crore.

What's Changed

• The subsidiary's active capacity grew from 105.95 MW / 423.80 MWh to 159.58 MW / 638.32 MWh (derived: +53.63 MW and +214.52 MWh).
• Secured commercial operations clearance for Phase-III with COD set for October 2, 2026.

Key Takeaways

• ACME Solar has commissioned Phase-III of its utility-scale BESS component, expanding its storage capacity in the high-potential Bikaner hub of Rajasthan.
• Power offtake is protected against merchant pricing fluctuations through a long-term Power Purchase Agreement (PPA) with SJVN Limited.
• Phased development allows the company to test grid stability and optimize discharge economics prior to full-capacity completion.
• The commissioning matches a broader deployment trend, occurring alongside a parallel Phase-I BESS commissioning in Chittorgarh by another subsidiary.

SAHI Perspective

ACME Solar's dual commissioning of storage assets in Bikaner and Chittorgarh reflects an aggressive pivot to monetize peak-demand power arbitrage in India's shifting electricity grids. By installing over 107 MW of storage capacity in a single day, the developer mitigates grid curtailment risks for its upcoming solar generation blocks. The secure PPA structure with SJVN Limited anchors long-term revenues, mitigating spot electricity price volatility and supporting credit profiles for fast-paced, capital-heavy infrastructure deployment.

Market Implications

The expansion places ACME Solar in a highly competitive position for upcoming Firm and Dispatchable Renewable Energy (FDRE) tenders. DISCOMs increasingly favor hybridized capacity with integrated storage to handle evening peak loads. Active BESS capacity allows ACME Solar to explore lucrative peak-hour merchant sales or participate in ancillary grid services, strengthening overall asset yield profiles ahead of full project commercialization.

Trading Signals

Market Bias: Bullish

Phased commissioning of utility-scale storage assets increases operational capacity, matching strong earnings momentum from Q1 FY27 where consolidated net profits grew 79.9% YoY to ₹235.3 crore.

Overweight: Renewable Energy, Power Utilities, Battery Infrastructure

Trigger Factors:

• Commercial Operation Date (COD) activation on October 2, 2026, commencing formal billing cycle under the PPA.
• Staged integration and COD of the corresponding solar generation blocks in Rajasthan.
• Q2 FY27 earnings release to evaluate the initial operational contribution of newly commissioned BESS phases.

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

Industry Context

India's National Electricity Plan requires massive deployments of energy storage to balance the 2030 renewable energy target of 500 GW. State-backed entities like SJVN and NTPC are actively securitizing these capacities via FDRE structures. Developers also benefit from central policy support, including transmission charge waivers (ISTS) and Approved List of Models and Manufacturers (ALMM) extensions, lowering developer capital risks.

Key Risks to Watch

• Under-Construction Solar Component: Only the BESS component is currently active, while corresponding solar generation components remain under development.
• Capital Intensity and Financing: Utility-scale BESS requires significant debt funding, elevating interest expenses (interest costs in Q1 FY27 rose to ₹344 crore vs ₹233 crore YoY).
• Supply Chain Constraints: Import reliance for lithium-ion storage cells exposes subsequent project phases to currency and global commodity price swings.

Recent Developments

On September 30, 2026, ACME Solar also commissioned its 53.73 MW / 222.969 MWh Phase-I BESS project in Chittorgarh, Rajasthan. Prior to this, the company commissioned Bikaner Phase-II (52.32 MW / 209.28 MWh) on September 17, 2026, and Bikaner Phase-I (53.63 MW) on September 14, 2026. On August 26, 2026, its subsidiary ACME Marigold Urja signed a 25-year PPA with Northeast Frontier Railway for a 130 MW solar project.

Closing Insight

Phased execution at the Bikaner complex demonstrates ACME Solar's robust project delivery capabilities. By scaling up its battery storage asset base, the company transitions successfully from a pure-play solar producer to a high-value, dispatchable smart power major.
