Bihar State Power Generation Company (BSPGCL) has invited bids for the engineering, procurement, and construction (EPC) of a 116 MW solar project and a 241 MWh battery energy storage system (BESS) in the Lakhisarai district.

The projects’ estimated work cost is ₹10.64 billion (~$123.39 million).

Bids must be submitted by April 10, 2025. Bids will be opened on the same day.

Bidders must submit a tender fee of ₹29,500 (~$342) and an earnest money deposit of ₹106.4 million (~$1.23 million).

Successful bidders must submit 10% of the EPC contract price as a bank guarantee within 30 days of receiving the letter of intent.

They must complete the EPC work within 18 months of receiving the work order and undertake comprehensive operation and maintenance activities for ten years.

The BESS must deliver a maximum power of 50.5 MW for four hours.

Selected bidders must use solar modules from the Ministry of New and Renewable Energy’s List-I under the Approved Models and Manufacturers of Solar Photovoltaic Modules.

Bidders must have commissioned solar projects with a cumulative capacity of at least 150 MW in India during the last 10 years. Of this capacity, bidders must have commissioned either one project of at least 60 MW, two projects of at least 45 MW each, or three projects of at least 30 MW.

Only ground-mounted solar projects with a minimum capacity of 1 MW will be considered for meeting the cumulative capacity requirement.

Bidders must have commissioned or are in the process of commissioning at least one grid-connected BESS of a minimum capacity of 5 MWh in India or abroad.

Alternatively, bidders must own and operate a battery manufacturing facility in India with a production capacity of over 500 MWh, using lithium-ion or other battery technologies. This facility must be operational at the time of bidding.

Bidders must have a cumulative turnover of ₹13.5 billion (~$156.57 million) in the last three financial years and a positive net worth in the previous financial year.

In October last year, BSPGCL invited bids to develop ground-mounted solar projects with a total capacity of 20 MW on private ponds using raised mounting structures under the renewable energy service company model.
