The Solar Energy Corporation of India (SECI) has invited global bids for setting up of 14 MW solar power plant with 42 MWh battery energy storage system in Union Territory of Ladakh. Tendered under Prime Minister Development Package (PMDP) 2015, the capacity shall come up at Leh and Kargil districts (7 MW with 21 MWh each) and is to be developed on “build own operate” basis.
The buying entity shall enter into a power purchase agreement (PPA) with the selected bidder for a period of 25 years with the maximum levelized tariff payable fixed at Rs 2/KWh for the PPA duration.
Battery energy storage system with the solar PV project has been incorporated with the objective of providing peak power requirements up of to 3 hours at rated power in the evening. In addition, it shall support stable and secure operation of the grid that includes diesel generators.
The projects are to be developed under Open category, where modules can be procured from either domestic manufacturers or imported, provided these are included in the Ministry of New and Renewable Energy‘s “Approved List of Models and Manufacturers.”
The land for setting up of solar projects with battery storage will be made available to the solar developer by Ladakh Renewable Energy Development Agency and Kargil Renewable Energy Development Agency separately. The plant should be designed for interconnection with the nearest substation of the buying entity at the voltage level of 11 kV
The developer shall be given a viability gap funding (VGF) by SECI. Bidding will be carried out by SECI based on the VGF requirement to be quoted by the bidders for setting up the project. The project will be awarded to the bidder who has quoted the lowest VGF.
The upper limit for VGF to be quoted by a bidder is kept at Rs 130 million for 1 MW solar PV project with battery storage of 3 MWh.
