The West Bengal Power Development Corporation (WBPDCL) has invited bids for comprehensive operation and maintenance (O&M) of a 1.891 MW rooftop solar project at Kolaghat Thermal Power Station for two years.

Bids must be submitted by March 29, 2025. Bids will be opened on April 2.

Bidders must submit an earnest deposit of ₹89,332 (~$1,027.32).

Successful bidders must furnish a performance bank guarantee of 10% of the contract value within 30 days of the work order issuance. They must also submit a performance security of 10% if the accepted bid value is 80% or lower than the estimated value.

The scope of work entails comprehensive maintenance of all solar components, routine inspections, periodic module cleaning, real-time performance monitoring, and adherence to safety protocols. It also includes maintaining a project uptime of over 98% and submitting periodic reports on energy generation and system performance.

The project covers installations at six locations with a cumulative capacity of 1,890.88 kW:

• Power House- unit 1(553.28 kW)
• Power House- unit 3 (547.2 kW)
• Power House- unit 6 (547.2 kW)
• ERC Building (65.92 kW)
• GM Building (36.48 kW)
• School Building (140.8 kW)

Due to the planned demolition of Power House units 1 and 2, the 553.28 kW solar modules must be relocated to a ground-mounted system within the project premises while maintaining uninterrupted operations.

Bidders must have operated and maintained rooftop, ground-mounted, or floating solar systems with at least one project having a capacity of 1.5 MW, two projects of 1 MW, or three projects of 0.89 MW. These projects must have been executed for central/state government entities or industrial organizations.

Bidders must have a minimum annual turnover of ₹669,989.52 (~$7,704.88) over the last three financial years and a positive net worth for each.

The contract includes a performance penalty clause based on the project’s performance ratio. If the ratio falls below 70%, deductions ranging from 1% to 3% of the monthly contract value for each percentage drop will apply. A ratio below 55% will result in no monthly payment.

Project delays will attract liquidated damages of 0.5% of the contract value per week, capped at 10%.

Recently, West Bengal State Electricity Distribution Company invited bids to implement a 6 MW floating solar project at PPSP Upper Dam, Purulia Pump Storage Project Site, Purulia, West Bengal.

In August 2024, WBPDCL invited bids to operate and maintain a 3.5 MW rooftop solar project at the Sagardighi thermal power project.
