Tata Power Renewable Portfolio Grows at 18.4% CAGR as Coal Additions Halt

Tata Power's renewable energy generation portfolio has grown at a compound annual growth rate of 18.4% from March 2015 to March 2023, nearly quadrupling in capacity, while its thermal portfolio grew at only 2.3% CAGR over the same period with no new coal capacity added since 2020. The company has secured US$525 million in equity investment from Mubadala and BlackRock for its renewables platform as global investors back India's clean energy transition.

Tata Power has committed to carbon net zero by 2045 and has stopped building new coal or fossil fuel-based power plants. Beyond grid-scale generation, the company has built a presence across the clean energy value chain: its solar engineering, procurement and construction order book stands at close to Rs100 billion excluding own projects; it operates a rooftop solar channel network in more than 275 districts; and it has installed more than 100,000 solar pumps. The company recently entered the public electric vehicle charging infrastructure segment, with close to 4,500 public chargers already installed.

Tata Power is setting up 4 GW of solar module manufacturing capacity under the government's production-linked incentive scheme, providing downstream cost control and exposure to the growing domestic and global solar manufacturing market. The company's clean energy strategy aligns directly with the Indian government's priorities including EV charging, rooftop solar, solar pumps, and domestic module manufacturing. Improving ESG disclosure scores have enabled the company to attract sustainability-linked financing from international lenders for the first time, including a US$320 million sustainability-linked loan facility.

Tata Power signed a US$54 million sustainable trade finance facility with Japan's MUFG and received the US$525 million equity investment from Mubadala, in partnership with BlackRock, in its renewables platform. These transactions demonstrate a replicable model for Indian utilities seeking to mobilise international green capital: credible decarbonisation targets, strong ESG disclosures, and a diversified clean energy business across generation, manufacturing, and distributed energy services. As India seeks to mobilise large-scale financing from global capital markets for its energy transition, Tata Power offers a benchmark for how integrated clean energy utilities can attract both equity and debt from sustainability-mandated international investors.

Key figure — 18.4% CAGR — Tata Power's renewable energy generation portfolio growth rate from March 2015 to March 2023, with the portfolio nearly quadrupling over the period.
