India’s Tata Power announced a $8.5 billion investment to develop 10 gigawatts of solar and wind energy capacity in the country’s southern state of Tamil Nadu over the next 5-7 years. Unveiled by Tata Power CEO Praveer Sinha at the Tamil Nadu Global Investors Meet, this aligns with the company’s vision to achieve 70% clean energy production by 2030 and full carbon neutrality by 2040.
As Sinha emphasized, renewable energy is crucial for mitigating climate change and securing India’s sustainable future. Tata Power currently has 982 MW of wind power capacity across seven states, making it a leader in wind generation. Its subsidiary Tata Power Solar has over 11.5 GW of utility-scale solar systems and over 1.7 GW of rooftop solar across India, plus over 100,000 solar water pumps.
The new 10 GW project reinforces Tata Power’s status as a major driver of India’s renewables expansion.
India’s total renewable energy capacity has crossed 179.5 GW, making it the 4th largest globally in wind and solar. This green surge is powering India’s homes, industries and stock markets while enabling ambitious climate goals. Per the REN21 Renewables 2022 Global Status Report, India is cementing its position as a global renewables leader.
With its Tamil Nadu investment, Tata Power aims to capitalize on this momentum. The project will support India’s aim of 500 GW renewable energy capacity by 2030 and net zero emissions by 2070. For Tata Power, it accelerates their clean energy transition and demonstrates the viability of large scale renewable energy development.
The announcement underscores the key role of private sector investment in unlocking India’s immense renewables potential and building national energy security.
