• TPREL signs its first standalone Battery Energy Storage Purchase Agreement (BESPA) with NHPC for a 30 MW / 120 MWh BESS project in Kerala.
• The project aims to enhance peak demand management, grid stability, and renewable integration under India’s 500 GW non-fossil target by 2030.
• With this win, TPREL’s total renewable capacity reaches 10.9 GW, reinforcing its leadership in sustainable energy solutions.

Tata Power Renewable Energy Limited (TPREL), a subsidiary of Tata Power, has signed its first Battery Energy Storage Purchase Agreement (BESPA) with NHPC Limited. This landmark project, awarded through NHPC’s BESS Tranche-I tender via competitive bidding, will see the deployment of a 30 MW / 120 MWh standalone Battery Energy Storage System (BESS) at a 220 kV substation in Kerala.

The project is designed to support Kerala State Electricity Board Limited (KSEB) as the end-user and is set to enhance peak demand management, bolster grid flexibility, and facilitate the integration of renewable energy sources into the state’s power infrastructure. It aligns with NHPC’s larger initiative to install 125 MW / 500 MWh of standalone BESS capacity in Kerala under the Tariff-Based Competitive Bidding framework, supported by Viability Gap Funding (VGF).

Planned for commissioning within 15 months, the project will operate under a 12-year BESPA and is part of the Government of India’s ambitious target to achieve 500 GW of non-fossil fuel capacity by 2030. It also complies with the Ministry of Power's strategic roadmap for strengthening energy storage infrastructure across the country.

This partnership marks a significant milestone for TPREL, marking its first foray into the standalone battery storage segment. The company is already managing a combined Solar and BESS project in Rajnandgaon, Chhattisgarh, featuring a 100 MW solar PV plant with a 120 MWh battery system under an EPC contract from the Solar Energy Corporation of India.

With this new project, TPREL’s total renewable capacity has reached approximately 10.9 GW, including 5.6 GW operational (4.6 GW solar, 1 GW wind) and 5.3 GW under various stages of development further strengthening its leadership in India’s clean energy transformation.
