ACME Solar Commissions 33.3 MW BESS Phase 1 in Rajasthan

ACME Solar Holdings Limited has commissioned 33.335 MW of Battery Energy Storage System (BESS) capacity, with its subsidiary ACME Sun Power Private Limited adding 160.48 MWh.

Reader Takeaway: BESS phase one operational boosts grid stability; scaling up the 300 MW project is next.

What just happened (today’s filing)

ACME Solar Holdings Limited has successfully commissioned the first phase of its Battery Energy Storage System (BESS) project. This initial phase adds 33.335 MW of capacity and 160.48 MWh of energy storage.

The project is being developed by its subsidiary, ACME Sun Power Private Limited, and is located in Rajasthan. Commercial operations for this phase are slated to begin on March 8, 2026.

This commissioning marks a key step in the company's larger plan to deploy a total of 300 MW / 1400 MWh through its BESS initiative.

Why this matters

Battery Energy Storage Systems (BESS) are crucial for the Indian power sector. They help integrate renewable energy sources like solar and wind, which are intermittent, by storing excess power and releasing it when needed.

This enhances grid stability, reduces reliance on fossil fuels for peak demand, and supports the country's ambitious renewable energy targets. ACME Solar's expansion in this area positions it to play a significant role in India's energy transition.

The backstory (grounded)

ACME Solar Holdings Limited, a prominent Indian renewable energy independent power producer (IPP), is actively expanding its BESS portfolio. The company has been commissioning various phases of its BESS projects in Rajasthan.

Most recently, on March 5, 2026, ACME Solar commissioned the second phase (38 MW/82 MWh) of a separate 285 MW/600 MWh BESS project in Jaisalmer, Rajasthan. The first phase of that project was commissioned in late February 2026.

The current announcement pertains to a distinct, larger 300 MW/1400 MWh project, of which this 33.335 MW/160.48 MWh phase is the first part to become operational.

What changes now

• The company's operational BESS capacity increases, contributing to its overall renewable energy infrastructure.
• Enhanced ability to support grid stability and manage peak power demand in Rajasthan.
• The company moves closer to realizing its full 300 MW/1400 MWh BESS project vision.
• It strengthens ACME Solar's position as a key player in India's growing energy storage market.

Risks to watch

During the quarter ending December 31, 2025, ACME Solar Holdings Limited reported no fines or penalties imposed against the Company.

Peer comparison

ACME Solar operates in a competitive BESS landscape. Peers like Waaree Energies, Tata Power, Amara Raja Energy & Mobility, and Exide Industries are also significantly investing in and expanding their energy storage solutions in India. These companies are also focusing on utility-scale BESS projects to support renewable energy integration.

Context metrics (time-bound)

• ACME Solar Holdings had a trailing 12-month revenue of approximately $225 million as of December 31, 2025.
• For FY2025, consolidated revenue was INR 14,051.31 million, with a consolidated Net Profit of INR 2,508.21 million.

What to track next

• The commissioning timeline and progress of subsequent phases for the 300 MW/1400 MWh BESS project.
• The company's overall BESS portfolio expansion targets.
• Any updates on the operational performance of the newly commissioned phase.
• ACME Solar's broader strategy for integrating BESS with its renewable energy generation assets.
• Any Power Purchase Agreements (PPAs) secured for the storage capacity.
