SECI Floats 1.2 GW Solar + 600 MW/3,600 MWh Storage Tender

SECI has issued a tender to select solar developers for developing 1200 MW solar projects with 600 MW/3600 MWh Energy Storage Systems (ESS). The online bid for the project will be open uptill August 18th.   

SECI tender facilitates the co-location of energy storage with the solar project, and it mandates the addition of an Energy Storage System (ESS) of at least 0.5 MW/3 MWh capacity for a 1 MW project as part of the project. It allows the developer to change the ESS technology at any time during the Term of the PPA. Additionally, SECI in its tender clarified that the ESS can be owned by the solar developer or be tied up separately with a third party by the solar developer. Additionally, the tender explained, “A single Project can be set up at multiple locations with different Delivery Points. The ESS component needs to be co-located with the Project. But, in case of a Project located at multiple locations, the ESS needs to be co-located with at least one of the components.” 

Criteria for Energy Supply 

For the supply of power in hours other than Peak Hours, the SECI tender requires the bidder to declare the annual CUF of the Projects while submitting their response to the tender. Furthermore, the tender allows the SPDs to revise the same once within the first year after the commencement of power supply from the full Project Capacity. The revised CUF shall be greater than the CUF initially quoted by the Bidder.  Thereafter, the CUF for the Project shall remain unchanged for the entire term of the PPA. 

The tender mandates that the declared/revised annual CUF be less than 19% and mandates that the margin should not exceed 30%. The developer is expected to maintain generation to achieve annual CUF within + 10% and -15% of the declared value till the end of 10 years from the Scheduled Commencement of Supply Date (SCSD).
