Tata Power, India’s largest vertically integrated power company, is charting a smooth transition towards becoming a fully clean and green energy producer by 2045, steadily reducing its dependence on thermal power generation.  

Currently, nearly 53% of Tata Power’s operational capacity of 16.7 GW comes from thermal power, which was over 80% a decade ago. However, with its ongoing project pipeline, the company expects its total installed capacity to rise to 26.3 GW while the share of thermal power generation declines sharply to 34%.  

Once the projects under execution are commissioned, nearly 66% of Tata Power’s generation capacity will come from clean and green energy sources. Solar power is expected to contribute around 20% of the overall portfolio while hybrid projects, pumped storage, and hydro projects will each account for about 10%. The remaining share will come from wind projects, complex/FDRE projects and waste heat recovery systems (WHRS).  

The pipeline includes 434 MW of wind projects, 612 MW of solar capacity, 1,725 MW of hydro projects, 2,447 MW of complex/FDRE projects, 2,800 MW of pumped storage capacity, and 1,612 MW of hybrid projects. These additions will take Tata Power’s overall operational capacity to 26,347 MW. The company is also exploring small modular reactors (SMRs) as part of a future entry into nuclear energy generation.  

Tata Power aims to increase the share of clean and green energy capacity to at least 70% by 2030. The company expects to complete its transition into a 100% clean and green energy producer by 2045, by when all long-term power purchase agreements (PPAs) linked to its thermal portfolio are expected to expire.  

The company currently operates several major coal-fired thermal power plants, including the 4,000 MW Mundra Ultra Mega Power Plant in Gujarat, the 1,580 MW Trombay Thermal Power Station in Mumbai, and the 1,050 MW Maithon Power Plant in Jharkhand.  

“Aligned with India’s clean energy ambitions, we continue to strengthen our capabilities across generation, transmission, distribution and customer-centric solutions, thereby building a greener and smarter tomorrow. Our focus on rooftop solar solutions, manufacturing-linked self-reliance and deeper backward integration will play a key role in enabling dependable and future-ready energy systems, driving Tata Power’s growth,” said CEO & MD Praveer Sinha while announcing the company’s Q4 and FY26 results.  

In FY26, Tata Power supplied 49.52 billion units of electricity to the grid while its distribution companies supplied around 47.92 billion units to consumers. The company reported revenues of ₹63,681 crore and a profit after tax (PAT) of ₹5,118 crore. Renewable energy emerged as a major growth driver, with revenues from the segment rising to ₹15,028 crore in FY26, compared with ₹9,876 crore in the previous year.  

The company, along with Druk Green Power, is also planning to develop 5.5 GW of clean energy projects in Bhutan, alongside its continued focus on solar and rooftop energy projects in India.  

Tata Power is developing two large pumped hydro storage projects in Maharashtra — the 1,000 MW Bhivpuri PSP and the 1,800 MW Shirwata PSP — which are expected to be operational by 2028 and 2029 respectively. The company has also signed MoUs for large FDRE and hybrid energy projects with SJVN, NTPC, and MSEDCL.
