The North Eastern Electric Power Corporation (NEEPCO) has invited bids from empaneled channel partners to set up grid-connected rooftop solar systems across three northeastern states.

The systems, ranging from 1 kW to 10 kW,  will be installed across Tripura, Meghalaya, and Mizoram.

NEEPCO said the cumulative indicative capacity across all three states could range from approximately 1 kW to 300 kW, depending on consumer response and the effectiveness of implementation under the PM Surya Ghar program.

Bids must be submitted by May 21, 2026, and will be opened on May 22. An earnest money deposit of ₹283,000 (~$2,978) is required.

Selected bidders must submit a performance bank guarantee of 5% of the order value.

Participation in all three states is mandatory; submissions that cover fewer than three states will be automatically and summarily disqualified without evaluation.

The scope of work entails the design, storage, transportation, installation, and commissioning of the solar projects. It also involves providing operation and maintenance services for five years.

Successful bidders must facilitate the consumer-NEEPCO agreement, provide training, and obtain the approvals, documentation, warranties, and insurances for the rooftop solar projects.

Selected bidders must contact consumers within 3 working days to arrange project site visits. They must undertake detailed site surveys covering roof area assessment, structural adequacy verification, electrical infrastructure evaluation, accessibility assessment, constraint identification, measurement, and photographic documentation, as well as discussions with consumers about system options.

They must also prepare the site survey report and share it with NEEPCO.

The rooftop solar projects must use modules listed in the Approved List of Models and Manufacturers and inverters that meet Class-I local content criteria.

The modules must have a rated power tolerance of up to ±3% and a fill factor of 75%. The solar inverters must have an efficiency of at least 97%.

The projects must have a minimum performance ratio of 75% and an annual availability of 98% for five years. They must be completed within 45 days.

Delays will attract liquidated damages of 0.5% of the unit contract price per week, capped at 10%. NEEPCO may also reassign work at the contractor’s risk and cost. Defects in projects must be rectified and can incur penalties of ₹1,000 (~$10.52)/kW for defects or unauthorized commissioning, along with mandatory rectification and payment withholding.

Bidders must be Class-I local suppliers. The work allocation is demand-driven, with no minimum work guarantee.

They must demonstrate financial capability at a minimum cumulative capacity of 300 kW across the three states.

Bidders must have had an average annual turnover of ₹5.91 million (~$62,216.11) during the last three consecutive financial years. They must have had a positive net worth in at least the last two of the previous three financial years.

Bidders must have a minimum working capital of ₹788,390 (~$8,295.38) as per the latest completed financial year for which an audited balance sheet is available. They must have a minimum bid capacity of ₹14.19 million (~$149,306).

In 2024, NTPC Green Energy, on behalf of NEEPCO, invited bids for the engineering, procurement, and construction package, including land, for up to 300 MW of inter-state transmission system-connected solar power projects anywhere in India.
