ReNew Power, Solarcraft Power, Mahindra Susten, and Avaada Energy won the Gujarat Urja Vikas Nigam’s (GUVNL) auction to supply power from 500 MW of grid-connected solar projects (Phase XIX).

The developers can build projects anywhere in India and avail a greenshoe option of an additional 500 MW.

ReNew Solar Power won 200 MW by quoting ₹2.71 (~$0.0333)/kWh. Avaada Energy won 140 MW at ₹2.75 (~$0.0335)/kWh out of the quoted capacity of 500 MW under the bucket-filling method.

Mahindra Susten and Solarcraft Power won 100 MW and 60 MW, respectively, at the tariff of ₹2.74 (~$0.0334)/kWh.

The tender was floated in February this year.

The successful bidders will have to sign power purchase agreements (PPA) with GUVNL within 30 days from the issuance of the letter of intent.

The tender specified that only commercially established technologies can be used to minimize the technology risk and achieve the projects’ timely commissioning.

The successful bidder would have to set up the projects, including the electrical network, up to the delivery point at its own cost.

The projects should be designed to deliver energy at the Gujarat Energy Transmission Corporation (GETCO) periphery. The successful bidder will be responsible for getting the grid connectivity with GETCO or the central transmission utility (CTU).

Solar projects will also be allowed to be set up in the existing wind farms, which are already connected to the grid, subject to the availability of spare capacity for renewable energy integration at the corresponding GETCO or CTU substation.

The declared annual capacity utilization factor (CUF) should not be less than 17%. The successful bidder should maintain generation to achieve annual CUF within + 10% and (-)15% of the declared value until the end of ten years from the commercial operation date and within +10% and (-)20% of the declared value of the annual CUF after that until the end of the PPA duration of 25 years.
