This expansion takes the overall partnership beyond 130 MW of reliable hybrid renewable energy capacity across key data centre hubs in Tamil Nadu and Maharashtra, CleanMax said in a statement.
As part of the arrangement, STT GDC India will further scale its contracted green energy capacity in captive mode, with a 26 percent equity investment in the renewable energy project.
Commenting on the development, Kuldeep Jain, Managing Director, Clean Max Enviro Energy Solutions, said, “The future of digital infrastructure will be defined as much by how it is powered as by how it is built. As Al and data-led growth accelerate, integrating renewable energy at scale is essential to ensuring long-term competitiveness, resilience, and responsible growth. Our expanding partnership with STT GDC India reflects a broader shift among leading digital infrastructure service providers to embed clean energy into their core business strategy, making it central to how they scale sustainably.”
Bimal Khandelwal, Chief Executive Officer, STT GDC India, said, “India's digital growth is entering a defining phase, where scale must be matched with responsibility. At STT GDC India, we take a deliberate approach to how we build, power and operate capacity for the long-term, sustainable growth. Our expanded partnership with CleanMax strengthens our ability to secure renewable energy at scale, supporting the rising intensity of AI-led and high-density workloads. This is critical to sustaining performance in an increasingly compute-driven world. We remain firmly on track towards carbon neutrality by 2030, with renewables already contributing approximately 70 percent of our energy mix as of CY 2025.”
The surge in AI-driven workloads and always-on digital services is redefining how data centres are powered. Energy is no longer a background enabler; it is now central to how infrastructure performs, scales and remains cost-efficient in an increasingly compute-intensive world. In response, operators are rethinking their energy strategies, with renewable solutions emerging as a critical lever to ensure reliability while aligning with evolving sustainability expectations, CleanMax stated.
Against this backdrop, the partnership further strengthens CleanMax's growing role in powering India's digital backbone. The Al and data centre segment now accounts for approximately 42 percent of its contracted capacity of 5.7 GW, representing nearly a tenfold expansion over the past two years, the company stated.
