The tender forms part of SECI’s broader efforts to reinforce power transmission infrastructure supporting large-scale, grid-connected renewable energy projects across India. By strengthening substations and transmission capabilities, the initiative aims to improve grid stability and facilitate the seamless integration of renewable power.
Under the scope of work, the selected bidder will be responsible for end-to-end execution, including engineering, design, manufacturing, and factory testing of the transformers.

Upon award, the successful bidder must furnish a Contract Performance Security equivalent to 10 percent of the total contract value, valid for a period of 31 months.
