ACME Solar Adds 95 MW Battery Storage in Rajasthan with New Project Phase
Overview

ACME Solar Holdings Limited is preparing to launch the fourth phase of its Battery Energy Storage System (BESS) project in Jaisalmer, Rajasthan. This expansion adds 95 MW of power capacity and 200.64 MWh of energy storage, increasing its total operational capacity to 171 MW / 361.14 MWh. The project phase is expected to begin commercial operations on March 25, 2026.

ACME Solar Expands Rajasthan Battery Storage Capacity

ACME Solar Holdings Limited is set to commission the fourth phase of its Battery Energy Storage System (BESS) project in Jaisalmer, Rajasthan. This expansion will add 95 MW of power capacity and 200.64 MWh of energy storage to the grid. Commercial operations are expected to begin on March 25, 2026.

Project Details

ACME Solar Holdings Limited, through its wholly-owned subsidiary ACME Suryodaya Private Limited, confirmed progress on its Jaisalmer BESS project. The fourth phase adds 95 MW of power and 200.64 MWh of energy storage, with a Commercial Operation Date (COD) set for March 25, 2026. This brings the total operational capacity at Jaisalmer to 171 MW / 361.14 MWh. The project's full planned capacity is 285 MW / 601.904 MWh.

Importance for Grid Stability

Battery Energy Storage Systems (BESS) are vital for integrating variable renewable energy sources, such as solar and wind, into India's power grid. These systems improve grid stability by storing surplus energy and supplying it during peak demand, thereby decreasing the need for fossil fuels. ACME Solar's BESS expansion supports India's increasing demand for energy storage and its renewable energy goals.

Company Expansion and Agreements

ACME Solar Holdings is a leading Indian renewable energy producer expanding its BESS portfolio nationally. The Jaisalmer site is part of a larger project planned for 285 MW / 600 MWh. Previously, ACME Solar commissioned the second phase of its Jaisalmer BESS project on March 5, 2026, adding 38 MW/82 MWh. The company also secured Battery Energy Storage Purchase Agreements (BESPA) with NHPC in June 2025 for two separate BESS projects totaling 275 MW/550 MWh. In September 2025, ACME Solar ordered 2 GWh of BESS capacity via POSCO International Corporation, signaling its commitment to securing substantial storage for future projects. The company targets approximately 17 GWh of BESS capacity across various Indian states.

Impact of the Expansion

The commissioning of Phase IV directly increases ACME Solar's operational BESS capacity, bringing the company closer to completing its full planned capacity at Jaisalmer. This expansion enhances grid support and contributes to a more reliable power supply. The BESS project is expected to generate future revenue through merchant sales and power purchase agreements (PPAs).

Sector Challenges

While no specific risks were detailed for this particular commissioning event, the broader battery energy storage sector faces ongoing challenges. These include managing technology costs, navigating supply chain dependencies, and adapting to evolving regulatory frameworks.

Competitive Landscape and Market Needs

ACME Solar operates in India's competitive BESS market. Key players include Tata Power Renewable Energy Ltd., Sterling and Wilson Renewable Energy Ltd., Amara Raja Energy & Mobility Ltd., and Adani Energy Solutions Ltd. The Central Electricity Authority projects a substantial demand for energy storage in India, estimating a need for 411.4 GWh by 2032, with 236.22 GWh specifically from BESS.

Looking Ahead

Key developments to watch include the official start of commercial operations on March 25, 2026. Investors will also track ACME Solar's progress on the remaining phases of the Jaisalmer project, alongside any new announcements about BESS capacity additions. Updates on the project's financial performance and its contribution to grid stability are anticipated.
