Goa Energy Development Agency Issues Tender for 300 MW Solar with 900 MWh Battery Storage

Bidding Deadline Set for March 6, 2026. The Goa Energy Development Agency (GEDA) has invited bids for the development of 300 MW of solar power projects integrated with a 150 MW/900 MWh Battery Energy Storage System (BESS). The projects will deliver firm and dispatchable renewable energy, ensuring peak power supply between 6 PM and 9 AM the following day.

Bids must be submitted by March 6, 2026, and will be opened on March 9. Interested bidders are required to furnish an earnest money deposit of Rs 50 million along with a tender document fee of Rs 50,000 plus GST. The selected developer must provide a performance bank guarantee of Rs 150 million.

Project Scope and Technical Requirements

The project will be connected to the state transmission utility (STU) network at the nearest 220 kV STU or GEDA substation. The delivery point will be defined at the 220 kV side of the 33/220 kV GEDA STU grid substation.

The scope of work covers complete design, engineering, procurement, construction, testing, and commissioning of both solar and storage components. It also includes evacuation infrastructure such as a 220 kV double-circuit transmission line, pooling substations, bay extensions, and substation upgrades.

The storage system must provide six hours of discharge duration. GEDA has specified a minimum annual capacity utilisation factor (CUF) of 19% and a maximum of 28%. The project must be fully commissioned within 24 months from the effective date of the agreement, with partial commissioning allowed in blocks of at least 50 MW along with proportionate storage capacity.

Eligibility and Compliance Criteria

Bidders must demonstrate a cumulative experience of at least 300 MW in ground-mounted solar installations over the past five years. They must also have experience in transmission and substation works, including commissioning at least three 400 kV AIS circuit breaker bays and a 20 km transmission line of 400 kV or higher.

Financially, bidders must have reported positive turnover over the last three financial years and maintain a minimum net worth of Rs 10 billion.

Delay in commissioning will attract penalties. Additional financial implications may arise if peak supply commitments are not met, if monthly storage availability drops below 95%, or if contracted supply falls short—at which point penalties may be levied at 1.5 times the prevailing market rate per kWh.

The tender mandates the use of solar modules listed under the Approved List of Models and Manufacturers (ALMM).
