GSECL tenders EPC work for 35 MW/57 MWh solar-plus-storage


Gujarat State Electricity Corporation Limited (GSECL) has invited bids to set up a 35 MW (AC) grid-connected solar power plant along with min. 57 MWh battery energy storage system (BESS) at its Kutch Lignite Thermal Power Station (Pandhro site) in the Kutch district of Gujarat. 

The scope of work involves the design, engineering, procurement and construction (EPC) of the grid-connected solar power plant, commissioning along with the BESS system, and evacuation of power into the GSECL/GETCO’s 66 kV substation. The contractor shall also be responsible for comprehensive operation and maintenance of the solar plant for 12 years

As per the tender document, out of total solar power generation, 70% power shall be directly injected/evacuated to the grid and 30% power shall be used for the BESS charging purpose. BESS must be designed such that 12 MW power for 4 hours (minimum 57 MWh) can be evacuated to the grid separately during grid peak time in the evening (between 06:00 PM to 10:00 PM) daily during the entire 12 years of O&M tenure. 

The energy storage system must consist of lithium-ion-type batteries only.

Further, only crystalline-silicon (poly or mono) solar modules are allowed for the project. The PV modules shall be of minimum 72 cell configuration with a rated power of module ≥300 Wp.
