Enviro Infra Engineers Limited (EIEL) has formally announced a strategic expansion into the renewable energy storage sector through its subsidiary, EIE Renewables Private Limited. On April 21, 2026, the subsidiary entered into a Share Purchase and Options Agreement to acquire PRA Bihar Bess Private Limited, a Special Purpose Vehicle (SPV) dedicated to developing battery storage infrastructure. This move marks a significant shift for the company as it integrates advanced energy solutions into its established infrastructure portfolio.

The acquisition involves a structured takeover where EIE Renewables initially acquired a 49% equity stake in the Target Company for a cash consideration of ₹15.51 Crores. The remaining 51% stake is scheduled for acquisition within 60 days of the project reaching its Commercial Operation Date (COD), with the total completion expected by May 31, 2027. The project itself is a 37.5 MW / 150MWh Battery Energy Storage System (BESS) to be established across multiple districts in Bihar under a Build-Own-Operate & Transfer (BOOT) mode. This venture is supported by a 12-year agreement with Bihar state power utilities at a tariff of ₹4,44,000 per MW per month and includes Viability Gap Funding (VGF) of up to ₹27 Lakh per MWh to enhance project feasibility.

Enviro Infra Engineers is a prominent player in India’s environmental infrastructure, traditionally focusing on water and wastewater treatment solutions like STPs and CETPs. Recent updates indicate a massive surge in their order book, which exceeded ₹4,600 Crores as of April 2026, following new order wins worth over ₹2,240 Crores. Key recent achievements include securing ₹972 Crores for STP projects in Pune and Nashik, and a ₹411 Crore project from the Bihar Urban Infrastructure Development Corporation. Additionally, the company has ventured into large-scale BESS projects for NTPC valued at approximately ₹1,070 Crores across multiple Indian states.

For the quarter ended December 31, 2025, the company reported a consolidated revenue of ₹250.02 Crores, reflecting a 9.97% growth compared to the previous quarter and a modest 1.04% increase year-on-year. The consolidated net profit for the same period stood at ₹40.41 Crores, which was a 17.06% decline from the previous quarter but a 10.11% increase compared to the corresponding quarter of the previous year.
