Purvah Green Power Private Limited, a unit of CESC Limited, has won a 250 MW ISTS wind project from Solar Energy Corporation of India Limited at a tariff of ₹3.69/kWh under Tranche-XIX bidding.
Purvah Green Power Private Limited (PGPPL), a subsidiary of CESC Limited , has acknowledged receipt and acceptance of the Letter of Award (LoA) from Solar Energy Corporation of India for developing a 250 MW ISTS-connected Wind power project under SECI’s Tranche-XIX tariff-based competitive bidding.
The project will supply interstate renewable power at a discovered tariff of ₹3.69/kWh for a period of 25 years from the scheduled commencement of supply, reinforcing Purvah’s growing presence in India’s competitive utility-scale wind market.
● Project Capacity : 250 MW Grid-Connected Wind Power
● Procurer : SECI (Tranche-XIX RfS)
● Tariff : ₹3.69/kWh
● PPA Tenure : 25 years
● Connectivity : ISTS-enabled interstate renewable supply
● Tender Size : Part of 1,200 MW SECI ISTS Wind Tranche-XIX
The award forms part of SECI’s broader initiative to scale up interstate renewable procurement and accelerate India’s non-fossil capacity addition through transparent tariff-based competitive bidding.
Project Scope and Execution Framework
Under the LoA, Purvah will develop, own, and operate the 250 MW wind project and supply power to SECI under a long-term PPA structure. The ISTS connectivity will allow flexible power offtake across multiple states, strengthening grid balancing and renewable integration.
The discovered tariff of ₹3.69/kWh aligns with recent competitive wind bids in India, reflecting improving project economics driven by higher-capacity turbines, optimized siting, and declining balance-of-plant costs.
Strategic Significance for Purvah and CESC
Purvah Green Power was established to lead the renewable energy expansion strategy of CESC Limited. Since its acquisition in 2024, the platform has rapidly scaled its project pipeline across solar, wind, hybrid, and round-the-clock renewable segments.
Current development pipeline includes:
~300 MW solar projects
~150 MW hybrid wind-solar projects
~180 MW round-the-clock renewable capacity
The 250 MW SECI wind award further strengthens Purvah’s position as an emerging utility-scale renewable IPP and aligns with CESC’s broader ambition to build a ~3.2 GW hybrid renewable portfolio across India.
Expanding Pan-India Renewable Footprint
As of early 2026, Purvah is actively expanding across high-resource renewable states including Rajasthan, Gujarat, Madhya Pradesh, Karnataka, Andhra Pradesh, and others. The ISTS-linked wind project will diversify its generation mix while increasing exposure to centrally contracted long-term renewable assets.
The company is currently developing an overall renewable portfolio of ~7.6 GW across solar, wind, and hybrid projects, with:
~3.8 GW connectivity approved by nodal agencies
~1.2 GW projects under active implementation
~1.2 GW PPAs already signed and under execution
Within a year of incorporation, PGPPL has emerged as one of India’s fastest-growing renewable IPPs and was recognized as the Fastest Growing Utility-Scale Project Developer of the Year 2024 by EQ Magpro.
Growth Roadmap to 2030
PGPPL aims to scale its renewable energy portfolio to ~10 GW by 2030, focusing on utility-scale solar, wind, and hybrid projects across high renewable-resource states. The latest SECI wind project award marks a significant milestone in this growth trajectory and underscores its competitive positioning in India’s central renewable auctions.
