Tata Power Renewable Secures First BESPA With NHPC, Strengthens Kerala’s Energy Resilience

Key Highlights:

- TPREL’s debut standalone Battery Energy Storage Purchase Agreement with NHPC.

- Aims to enhance grid stability and integrate renewables effectively.

- Strengthens TPREL’s position as a key renewable energy player in India.

Mumbai: Tata Power Renewable Energy Limited (TPREL), a subsidiary of The Tata Power Company Ltd, has secured its first Battery Energy Storage Purchase Agreement (BESPA) with NHPC Limited. The project, aimed at strengthening Kerala’s power infrastructure, marks TPREL’s foray into the standalone Battery Energy Storage System (BESS) segment.

This agreement is part of NHPC’s Battery Energy Storage System Tranche-I tender for the Kerala State Electricity Board Limited (KSEB), the end user of the storage solution.

Project Details and Strategic Impact

Under the BESPA, TPREL will develop a 30 MW / 120 MWh utility-scale BESS at a 220 kV substation in Kerala. The system will be commissioned within 15 months and will operate under a 12-year BESPA framework, governed by guidelines from the Ministry of Power.

The project aims to improve grid flexibility, address peak load requirements, and support the integration of renewable power, playing a crucial role in Kerala's energy transition strategy. It forms part of NHPC’s broader plan to develop 125 MW / 500 MWh of standalone BESS capacity in the state, enabled through a Tariff-Based Competitive Bidding (TBCB) model and backed by Viability Gap Funding.

Aligned with National Renewable Goals

This BESS project supports the Government of India’s national target of installing 500 GW of non-fossil fuel capacity by 2030. The deployment of such storage systems is expected to be a game-changer in managing India’s growing renewable energy supply and improving grid reliability.

TPREL’s existing experience in integrated renewable systems includes its Solar and BESS project in Rajnandgaon, Chhattisgarh, featuring a 100 MW solar plant combined with a 120 MWh storage system developed under an EPC contract by the Solar Energy Corporation of India (SECI).

Growing Renewable Footprint

With this new win, TPREL's total renewable portfolio has grown to 10.9 GW, including 5.6 GW of operational assets—comprising 4.6 GW solar and 1 GW wind—and 5.3 GW under development. This reinforces TPREL’s strategic commitment to clean, dispatchable energy solutions and advancing grid stability nationwide.
