SECI launches 1.2 GW hybrid wind-solar-storage tender


Solar Energy Corp. of India Ltd has opened bids to develop 1.2 GW of hybrid wind-solar power projects along with energy storage for assured peak power supply in India. The projects are to be installed on a ‘build-own-operate’ basis and connected to the interstate transmission network.

The minimum bid capacity will be a minimum of 50 MW and a maximum of 1.2 GW.

SECI will sign a 25-year power purchase agreement (PPA) with hybrid power developers at the tariffs discovered after the e-reverse auction, and back-to-back power sale agreements with the buying entities at the PSA tariff for the total capacity allotted.

“Identification of land, installation, and ownership of the project, along with obtaining connectivity necessary approvals and interconnection with the ISTS network for supply of power to SECI, will be under the scope of the hybrid power developer,” as per the tender document.

The rated capacities of both the solar and wind components will be a minimum of 33% of the total contracted capacity, for a project to qualify as a hybrid project. For example, in case the contracted capacity of a project is 100 MW, the rated capacities of both the wind and solar components shall be a minimum of 33 MW each.

Additionally, the hybrid power developer will install an energy storage system capacity of at least 100 MWh for each 100 MW project being contracted under the PPA.

The energy storage component will be mandatorily co-located either with solar PV or with wind Power generating components, under a single project.
