STT Global Data Centres India Private Ltd., India’s leading AI-ready colocation data centre services provider, has expanded its long-standing partnership with Clean Max Enviro Energy Solutions Limited through additional Power Purchase Agreements (“PPA”) executed this week.
The latest agreement includes an additional 21 MWp of solar capacity, augmenting CleanMax’s existing wind–solar hybrid power supply to STT GDC India’s data centres in Chennai, Tamil Nadu. 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. As part of the arrangement, STT GDC India will further scale its contracted green energy capacity in captive mode, with a 26% equity investment in the renewable energy project.
Partnerships of this nature reflect a more deliberate and future-ready approach by data centre operators, integrating solar and wind to ensure round-the-clock renewable energy supply. This model is becoming increasingly critical as AI-led workloads drive higher, more consistent energy demands.
Commenting on this, Mr. Kuldeep Jain, Managing Director, Clean Max Enviro Energy Solutions Limited said, “The future of digital infrastructure will be defined as much by how it is powered as by how it is built. As AI and data-led growth accelerates, integrating renewable energy at scale is essential to ensuring long-term competitiveness, resilience, and responsible growth. Our expanding partnership with STT GDC India reffects 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.”
Mr. 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% 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. Against this backdrop, the partnership further strengthens CleanMax’s growing role in powering India’s digital backbone. The AI and data centre segment now accounts for approximately 42% of its contracted capacity of 5.7 GW, representing nearly a tenfold expansion over the past two years. This momentum underscores CleanMax’s position as a trusted partner in supporting the digital economy’s transition towards a more sustainable, net-zero futur
