NHPC has issued a request for selection (RfS) to set up 13.255 MW of grid-connected rooftop solar projects across Sikkim, Manipur, and Nagaland.

Selected bidders will install 5,060 kW of solar projects in Sikkim, 5,627 kW in Manipur, and 2,568 kW in Nagaland.

Bids must be submitted by June 8, 2026. Bids will be opened on June 11, 2026.

Bidders must furnish earnest money deposits ranging from ₹100,000 (~$1,044.8) to ₹179,000 (~$1,870.18) for solar projects in Sikkim, ₹100,000 (~$1,044.8) to ₹401,000 (~$4,189.63) for projects in Manipur, and ₹100,000 (~$1,044.8) to ₹127,000 (~$13,26.89) for projects in Nagaland.

They must pay document fees ranging from ₹1,000 (~$10.45) to ₹1,500 (~$15.67) for projects in Sikkim, ₹500 (~$5.22) to ₹5,000 (~$52.24) for projects in Manipur, and ₹500 (~$5.22) to ₹1,500 (~$15.67) for projects in Nagaland.

Selected bidders must submit a performance security of ₹2,475 (~$25.86)/kW.

They must sign a 25-year power purchase agreement (PPA).

The scope of work entails the design, engineering, erection, testing, and commissioning of the solar projects. It also involves providing operations and maintenance services for the entire PPA period.

Successful bidders must undertake multi-level inspections and civil works. They must undertake packing and forwarding of equipment, as well as unloading and storage at the project site.

They must also obtain net metering, no-objection certificates, and other approvals, and ensure synchronization with the existing distribution network grid for individual solar projects across multiple locations.

Selected bidders must undertake a compulsory site visit to assess the feasibility of the space, sanctioned project loads, annual energy consumption, and other project requirements.

The projects must have an annual capacity utilization factor (CUF) of 14%. They must be commissioned within nine months.

Delays in commissioning can result in pro-rata encashment of the performance guarantee for the uncommissioned capacity, capped at 100%. Shortfalls in CUF can incur damages equal to 50% of the PPA tariffs. Failure to apply for net metering within 90 days may result in termination of the PPA.

Bidders must be Class-I and Class-II suppliers. This March, NHPC issued a request for selection to set up grid-connected rooftop solar projects on government buildings with a cumulative capacity of 30.93 MW across Haryana.
