Rewa Ultra Mega Solar

Rewa Ultra Mega Solar is a operational solar park spread over an area of 1,590 acres (6.4 km²) in the Gurh tehsil of Rewa district of Madhya Pradesh. The project was commissioned with 750 MW capacity in July 2018^[2].

Rewa Ultra Mega Solar Limited (RUMSL), the implementing agency of the project, is a joint venture between the Madhya Pradesh Urja Vikash Nigam Limited (MPUVNL) and the Solar Energy Corporation of India (SECI).

Minister of State for Renewable Energy Piyush Goyal informed the Lok Sabha in July 2014 that the government intended to construct a 750 MW solar park in Rewa.

PGCIL was awarded the contract for developing the 220/400 KV substation for the evacuation of power from the project site to different consumers. M/S Alstom was selected by PGCIL to develop the construction of substation work. Internal infrastructure for the project was developed by the RUMSL. RUMSL developed the project site which allowed developers to set up the unit without worrying about the evacuation infrastructure.

Auctions

RUMSL selected developers based on 3 stage assessment viz; Technical Proposal, Financial Proposal, Reverse Auction. RUMSL conducted the bid and reverse auction process using the Electronic Tender portal hosted by the Telecommunication Consultants India Ltd (TCIL).

The 750 MW capacity was auctioned in three packages of 250 MW each. RUMSL invited bids from solar power developers in January 2017. Twenty firms submitted bids, from which eighteen were shortlisted based on their financial and technical proposal to participate in the bidding process.^[3] The reverse auction process for the project involved 33 hours of non-stop bidding by the shortlisted bidders beginning at 10 AM on 9 February 2017. Mahindra Susten, ACME Solar Holdings, and Solengeri Power won the first, second and third units quoting tariffs of Rs 2.979, Rs 2.970 and Rs 2.974 for the first year of operations. In Jan 2017, these were the lowest tariffs ever awarded through a bidding process for a solar project in India, however is now higher than the INR 2.44/unit quoted in the new auctions for the Bhadla Solar Park.
