The Solar Energy Corporation of India (SECI), acting in its capacity as a Renewable Energy Implementing Agency (REIA), has issued a high-stakes tender for the procurement of five 160 MVA power transformers. The units are destined for the 700 MW (AC) grid-connected solar PV project at Radhanesda, Gujarat. Registered under Tender ID SECI000255 (Ref No: SECI/C&P/OP/11/04/2026-27), the procurement represents a critical link in the infrastructure chain for one of India’s most significant upcoming solar hubs. Bidders have until June 19, 2026, to submit their proposals.
Project Context and Financial Scale
The transformer tender is part of a synchronized procurement blitz for the 700 MW Radhanesda site, which is currently undergoing simultaneous tendering for solar modules and Balance-of-System (BOS) components. Developed under the Central Public Sector Undertaking (CPSU) Scheme Phase-II, the total project cost is estimated at approximately Rs 3,393.96 crore (net of Central Financial Assistance).
SECI has already secured a long-term power offtake arrangement with Gujarat Urja Vikas Nigam Limited (GUVNL) at a competitive tariff of Rs 2.45 per kWh. The project is slated to achieve its Scheduled Commercial Operation Date (SCOD) by February 6, 2028.
