Advait Energy Signs BESPA with GUVNL for 300 MWh Standalone BESS Project in Gujarat

Advait Energy Transitions has signed a Battery Energy Storage Purchase Agreement with Gujarat Urja Vikas Nigam for a 150 MW/300 MWh standalone BESS project in Gujarat. The company secured the project at GUVNL’s auction in February 2026 at a tariff of INR 2.10 lakh/MW/month. The project is expected to generate revenues of over INR 450 crore.

Advait Energy Transitions has announced that its subsidiary Advait BESS Bhesaan has executed a Battery Energy Storage Purchase Agreement (BESPA) with Gujarat Urja Vikas Nigam (GUVNL) for the development of a Standalone Battery Energy Storage System (BESS) project having an aggregate capacity of 150 MW/300 MWh.

The company secured the capacity in GUVNL's auction held in February 2026 for setting up 335 MW/670 MWh in Gujarat. Advait emerged as the L1 bidder and won 150 MW at a tariff of INR 2.10 lakh/MW/month. The company received the Letter of Intent (LoI) in April 2026.

The project will be developed in the vicinity of the 220 kV Bhesan AIS substation of Gujarat Energy Transmission Corporation (GETCO) and will be designed to provide reliable, dispatchable energy storage capacity to support Gujarat's evolving power infrastructure. Under the terms of the agreement, Advait BESS Bhesaan will develop, own and operate the project and make the contracted storage capacity available to GUVNL on a long-term basis. The BESPA has a tenure of 12 years from the effective date of signing, stated the company further adding that the project is expected to generate revenues of over INR 450 crore.

Commenting on the development, Vatsal Kundalia, Director of Operations, Advait Energy Transitions, said, "Battery energy storage is becoming one of the most critical building blocks of India's clean energy future. This project represents an important step in our journey to build scalable energy transition infrastructure that supports grid resilience and renewable energy integration. We are pleased to partner with GUVNL on this strategic initiative and remain committed to delivering reliable, future-ready energy solutions that contribute to India's long-term sustainability goals."

The projects will be eligible for viability gap funding (VGF) support at INR 18 lakh/MWh, and the projects must be completed within 18 months from the date of battery energy storage purchase agreement (BESPA), the company stated in a regulatory filing earlier.

The tender for this was floated in December 2025.

The BESSD must set up a BESS, with the primary objective of making the energy storage facility available to GUVNL for charging/discharging of the BESS, on an 'on demand' basis. Setting up the BESS and interconnection of the BESS with the State Transmission Network will be under the scope of the BESSD.

GUVNL will provide the required power for charging the BESS. The BESSD must take a separate, metered connection for the Auxiliary Power load of the BESS. Alternatively, the BESSD can draw auxiliary power from the interconnection point.

The BESSD shall make the BESS available for 2 operational cycles per day, i.e. 2 complete charge-discharge cycles per day. The BESSD must guarantee a minimum system availability of 95 percent on an annual basis.

The BESSD must ensure that the BESS can charge and discharge with a C-rate of 0.5. Additionally, the BESS must be capable of being charged or discharged in groups ranging from 50 MW/100 MWh το 100 MW/200 MWh, up to the total rated capacity specified in the agreement.

The applicable software for the Energy Management System (EMS) of the BESS project capacity must be developed indigenously within India.

BESSD must ensure a minimum local content of 20 percent of the total project cost in BESS procurements under the VGF Scheme. This minimum local content requirement shall include the indigenously developed EMS application software.

Advait Greenergy (AGPL), a subsidiary of Advait Energy Transitions, plans to launch a multi-gigawatt BESS manufacturing facility by November 2026. AGPL has signed an MoU with Wuhan Huagong International Development Co., Ltd (HGTECH) for the design, manufacture, supply, shipment, installation, commissioning, and acceptance of a 2.5 GWh BESS manufacturing line.
