CESC’s Purvah Green Power to Acquire 1.4 GW Solar Portfolio from ReNew for ₹48.59 Billion

Purvah Green Power Private Limited, the renewable energy arm of power utility CESC, has entered into a binding agreement to acquire a 1.4 GW (1,411 MWp) operating solar portfolio from ReNew Solar Power Private Limited. The transaction, valued at an enterprise value of ₹48.59 billion (₹4,859 crore), marks a strategic pivot for the RPSG Group as it aggressively builds scale to meet its long-term decarbonization targets and de-risk its procurement profile.

Financial Breakdown and SPVs

The acquisition is structured to provide immediate scale and stable, regulated-style returns. The following table summarizes the primary financial parameters of the deal:

Funding and Capital Structure The transaction involves the 100% acquisition of six Special Purpose Vehicles (SPVs) currently under ReNew Solar Power, including ReNew Hans Urja and ReNew Solar Photovoltaic. These assets are geographically concentrated in the high-irradiance states of Rajasthan and Karnataka.

CESC plans to fund the acquisition through a mix of debt and equity. While the company’s current liquidity of approximately ₹5,500 crore is adequate to meet the initial ₹1,600 crore equity requirement, the capital-intensive nature of the 10 GW trajectory suggests a different long-term financing strategy. Analysts expect Purvah Green Power to initiate a fresh equity fundraise by the end of FY28 to mobilize the incremental capital necessary for its expansive development pipeline.

Portfolio Operational Metrics & Offtake Agreements

The acquired 1,411 MWp portfolio is characterized by high-quality offtake arrangements that significantly mitigate counterparty risk.

• Contractual Strength: Over 90% of the portfolio’s capacity is tied to long-term Power Purchase Agreements (PPAs) with the Solar Energy Corporation of India (SECI).
• Secondary Offtakers: The remaining capacity is contracted with various Karnataka-based Power Distribution Companies (DISCOMs).
• Revenue Visibility: All agreements carry a 25-year tenure, providing a clear and stable cash flow profile for more than two decades.

Strategic Impact: Path to 10 GW

This acquisition acts as a major catalyst for Purvah Green Power, which is being positioned as a premier renewable energy platform. Beyond simply adding megawatts, the deal helps mitigate CESC’s current exposure to open-market procurement volatility—where the company currently sources approximately 25% of its power—by locking in fixed-rate renewable capacity.

• Platform Scaling: Following completion, Purvah’s total contracted capacity will rise to 4.5 GWp, consisting of 1.8 GWp in operational assets and 2.7 GWp under implementation or development.
• Growth Targets: The company has finalized plans to set up 3.2 GW of renewable capacity by FY29.
• Diversified Green Ecosystem: The platform’s ambition extends beyond solar and wind; it includes a 1.5 GWh Battery Energy Storage System (BESS) pipeline and the development of a 10,500-tonne annual green hydrogen production facility.
• Long-Term Goal: These initiatives provide a clear roadmap to the company’s stated objective of reaching a 10 GW renewable platform by FY32.

Corporate Context

The RPSG Group’s “10 GW ambition” is underpinned by the stable financial environment of CESC’s regulated standalone business in Kolkata and Haldia. Following the deal announcement, analysts at Elara Capital maintained a “Buy” rating on CESC with a target price of ₹228, citing the significant option value of incremental earnings from the renewable transition and the potential for corporate re-rating.

The acquisition is supported by a robust Q1FY27 performance for the parent company:

• Consolidated Revenue: ₹54.8 billion (up 5.4% YoY).
• Profit After Tax (PAT): ₹4.1 billion.
• Generation Volume: A 13% YoY increase to 1,668 MU, buoyed by higher thermal PLFs and the implementation of Fuel and Power Price Adjustment Surcharges (FPPAS) to recover costs.

While the expansion is aggressive, analysts note that the timely issuance of true-up orders and the management of execution risks in the 3.2 GW development pipeline remain key factors to monitor for the group’s credit profile.
