ACME Solar Expands Rajasthan BESS Capacity, Targets Full Project by Q3

Phase-II Commissioned: 52.32 MW / 209.28 MWh.

Cumulative Operational Capacity: 105.95 MW / 423.80 MWh.

Reader Takeaway: Capacity expansion improves execution visibility, but timely completion of the remaining project remains critical.

What just happened

ACME Solar Holdings Ltd has commissioned Phase-II of the Battery Energy Storage System (BESS) component of its Firm and Dispatchable Renewable Energy (FDRE) project located at Kelan village in Bikaner district, Rajasthan.

The newly commissioned phase adds 52.32 MW of power capacity and 209.28 MWh of energy storage capacity.

Following this milestone, the project's cumulative commissioned BESS capacity has increased to 105.95 MW and 423.80 MWh.

The commercial operation date for the newly commissioned phase is September 19, 2026.

Why this matters

Battery Energy Storage Systems are a key part of dispatchable renewable energy projects because they improve the reliability of renewable power supply by storing energy and supplying it when required.

The latest commissioning demonstrates continued execution of one of ACME Solar's large storage projects and increases its operational renewable energy assets.

The project also benefits from a long-term Power Purchase Agreement with SJVN Limited, providing visibility for future power offtake once the full capacity becomes operational.

The backstory

The BESS installation forms part of ACME Solar's larger 300 MW / 1,200 MWh Firm and Dispatchable Renewable Energy project.

Long-term financing for the project has been arranged through REC, supporting the development of the storage infrastructure.

What changes now

With Phase-II operational, the company has commissioned approximately one-third of the planned BESS capacity.

Management has guided that the remaining capacity will be commissioned by Q3 of the current financial year, making project execution over the next few months an important milestone.

Risks to watch

The key factor for investors is timely completion of the balance project capacity.

Delays in commissioning the remaining 194.05 MW and 776.20 MWh could shift the expected operational timeline.

What to track next

Investors should monitor:

• Progress toward commissioning the full 300 MW / 1,200 MWh project.
• Achievement of the Q3 commissioning target.
• Operational performance after commercialisation.
• Revenue contribution from the project under the SJVN power purchase agreement.
