SJVN has announced the results of its auction to procure 1.5 GW/6 GWh of assured peak power from ISTS-connected renewable energy projects with integrated energy storage systems (ESS).

Reliance NU Energies, Sembcorp Green Infra, Solarcraft Power India 8 (BluPine Energy), and ACME Solar Holdings have emerged as winning bidders to supply 6 GWh of assured peak power (1.5 GW for 4 hours).

Reliance and Sembcorp quoted a tariff of INR 6.74/kWh, securing 750 MW and 150 MW, respectively. Solarcraft Power India 8 won 150 MW at INR 6.75/kWh, while ACME secured 450 MW out of the 600 MW it bid for, under the bucket-filling allocation method.

The tender, issued in December last year, targets four-hour daily peak windows, either from 00:00 to 08:00 or 17:00 to 24:00. Projects can connect solar, wind, or storage capacities to the grid at various ISTS substations, with a minimum interconnection voltage of 220 kV.

Power purchase agreements (PPAs) will run for 25 years from the scheduled commencement of supply or from the date the full project capacity begins supplying power, whichever is later. Selected bidders are required to deliver 100 percent of annual energy as renewable, though up to 5 percent may be sourced through green market transactions or bilateral agreements.

Only commercially proven and operational technologies are allowed to reduce project risk and ensure timely commissioning. Wind turbines must be type-certified and listed in the MNRE’s Revised List of Models and Manufacturers, while solar PV modules must be included in the MNRE’s List-I of Approved Models and Manufacturers.
