ACME Solar Holdings has commissioned 35.715 MW / 160.512 MWh of additional Battery Energy Storage System (BESS) capacity in Bikaner, Rajasthan. This expansion is a strategic move within its renewable energy portfolio. The development comes amid strong government backing for India's energy storage sector, including substantial Viability Gap Funding and manufacturing incentives. On May 12, 2026, ACME Solar's stock showed resilience, rising slightly while major indices traded lower, indicating that company news must overcome broader market pressure.
The newly commissioned capacity, operating under ACME Surya Power Private Limited, brings ACME Solar's total operational BESS to 210.938 MW / 947.899 MWh. The capacity is set for commercial operations starting May 13, 2026. This expansion is vital for grid stability and integrating renewable energy sources. On May 12, 2026, ACME Solar's stock closed at ₹290.45, up 2.76%, bucking the Nifty 50's 1.49% drop. Recent financials highlight ACME Solar's strong performance, with FY26 revenue up 59.2% to INR 2,507 crore and profit after tax nearly doubling to INR 498 crore. The company reported a cash return on equity (ROE) of 20.1%.
India's Growing Energy Storage Market
India's energy storage sector is expanding rapidly, driven by government policies and ambitious targets. The government has allocated around ₹145 billion for Viability Gap Funding (VGF) for BESS projects and offers Production Linked Incentives (PLI) for domestic battery manufacturing. Projections indicate India will need approximately 2,000 GWh of BESS by 2050. This supportive environment has attracted significant investment from major players such as Adani Energy Solutions, Tata Power, and Reliance New Energy. ACME Solar operates in this dynamic market, facing competition from established companies like Exide Industries, Waaree Energies, and Amara Raja Energy & Mobility, as well as larger conglomerates. The overall market is forecast to grow from $2.19 billion in 2025 to $19.45 billion by 2035. However, the sector faces challenges, including concerns over extremely low bid prices that could impact project viability.
Concerns and Competition
Despite ACME Solar's expansion and recent financial gains, several factors signal caution. The company's valuation, with a P/E ratio between 34x and 50x, suggests a premium. While recent cash ROE improved to 20.1%, past interest coverage ratios have been low. Intense competition in India's renewable sector comes from Chinese component suppliers and large conglomerates like Adani Group and Tata Power, which have substantial capital. The rapid deployment of BESS capacity has led to concerns about exceptionally low bid prices, potentially affecting long-term profitability and safety. ACME Solar's growing footprint must be weighed against the larger investments and backward integration efforts of industry leaders.
Outlook
ACME Solar's investment in BESS aligns with India's need for energy storage to support its renewable energy transition. The company generates revenue from merchant power contracts, with its BESS operations realizing approximately INR 2.2 crore per day, supplementing traditional PPAs. Analyst sentiment for ACME Solar Holdings currently indicates a 'Buy' signal. With a substantial portfolio under construction and signed PPAs, the company is positioned to benefit from the energy transition, provided it can manage competition and maintain its financial health.
