Solar Energy Corporation of India (SECI) has invited proposals for setting up an aggregate 400 MW capacity of ISTS-connected renewable power projects anywhere in India. To be set up on a ‘build-own-operate’ basis, the projects can be augmented with appropriate energy storage systems for round-the-clock power supply.
SECI will enter into a 25-year power purchase agreement (PPA) with the selected developers and power procured from the above projects has been provisioned to be sold to the NDMC, New Delhi (200 MW) and Dadra & Nagar Haveli (200 MW) utility.
The bidders shall quote a single first-year tariff, which shall be escalated annually at 4%, up to the 15th contract year of the PPA term, and shall subsequently be fixed at the tariff thereafter for the remaining term of the PPA.
Project scope and technology selection
The entire capacity—comprising one or more renewable energy components (solar and wind), along with an energy storage system—would be set up in project sizes of 200 MW. A single developer may bid for a minimum of 200 MW, up to the whole of the 400 MW capacity.
Projects can be located anywhere in India. Land, connectivity and long-term open access shall be in the scope of the developer.
For setting up the projects, the developer shall strictly adhere to the respective MNRE guidelines for the renewable energy components (wind and solar), in line with the applicable policies of the State where the project is located.
The energy storage system, if any, can be based on battery, mechanical, pumped or any other technology. Further, the bidder has the flexibility to choose its energy rating.
The full project capacity must be commissioned within 18 months from the signing of the PPA. In case of delay beyond the scheduled commissioning date until 30 months from the effective date of the PPA issuance, the total performance bank guarantees shall be encashed on per-day-basis and proportionate to the balance capacity not commissioned.
