SECI has invited bids for BOS work for a 700 MW AC solar PV project, with about 2,638 acres of land to be provided on a government lease
The design uses 585 W mono-PERC modules for bidding, but the awarded project must use TOPCon modules
The scope includes engineering, supply (excluding modules and transformers), commissioning, performance testing, and 5 years of O&M
The Solar Energy Corporation of India (SECI) has invited bids for a balance of system (BOS) tender for an 870 MW DC/700 MW AC ground-mounted solar PV plant in Radha Nesda of Banaskantha district in Gujarat.
The DC capacity may be increased to up to 920 MW if higher wattage modules are used. For bidding purposes, SECI specifies a 585 W mono-PERC module design with 21.65% efficiency and dimensions of 2,382 × 1,134 mm. Once the tender is awarded, it requires the use of TOPCon technology with a module width of 1,134 mm+/- 2mm.
The broad scope of work includes design and engineering, procurement and supply of equipment and materials, excluding PV modules and transformers, testing, and commissioning.
Winning bidders will also need to conduct a performance demonstration with associated equipment and materials on a turnkey basis, along with 5 years of comprehensive operation and maintenance (O&M).
SECI launched the call on January 8, 2026. It will accept bids until January 29, 2026.
SECI will provide approximately 2,638 acres of land on a government lease for the project that will come up under the Central Public Sector Undertaking (CPSU) Scheme, Phase-II. Under this scheme, the government seeks to set up 12 GW of grid-connected solar PV capacity to be built by government-owned companies with viability gap funding (VGF) support.
While SECI was initially tasked with implementing this scheme, MNRE replaced IREDA as the implementing agency in April 2020 (see IREDA Replaces SECI For CPSU Phase-II Solar Scheme).
