The successful bidder should be taking care of the operation and maintenance activities of the projects for ten years and also has to commission the projects within nine months from the letter of award.

The bidders must have designed, supplied, and commissioned grid-connected solar projects with 4 MW or above cumulative capacity and a total of 2.65 MW solar capacity from this, should be commissioned and operated in India, in which one project must be of 1 MW capacity.

The overall revenue of the bidder must be at least Rs 162 million for the last three financial years. Moreover, their net worth should be positive during the previous financial year.

The modules should be examined by the IEC or a Ministry of New and Renewable Energy-recognized laboratory.

GSECL floated tender for the engineering, installation, design, supply and commissioning of 224 MW of grid-connected solar projects earlier this month, ranging from 10 MW to 55 MW at substations of the Gujarat Energy Transmission Corporation (GETCO).
