Maharashtra pulled the plug on a captive green energy scheme for data centers, impacting ₹10,000-12,500 crore in solar investments. The state discom changed tariff rules and added battery mandates just five months after attracting giants like Amazon and NTT with special incentives. Now, operators who already invested hundreds of megawatts in the state are stuck with projects whose economics no longer add up.
How We Got Here
In October, Maharashtra offered a special framework for data centers to build captive renewable energy projects, attracting major players. This incentive was crucial for companies like Amazon, NTT, and Equinix looking to power their facilities with cheap, clean energy.
The Numbers
- Mumbai hosts nearly 60% of India's data center capacity, projected to hit 1.5 GW by 2025.
- Seven major operators—Amazon, NTT, Ctrls, Equinix, Nxtra, Sify, and Princeton Digital Group—were granted the initial framework.
- Three of these companies have already built or contracted over 250 MW of captive solar capacity in Maharashtra.
- The state electricity distributor, Mahavitaran, doubled specific charges and ordered all new solar projects to include a battery.
- Mahavitaran initiated these changes to recoup revenue lost as high-paying customers left the grid for captive solar.
What Happens Next
🇮🇳 Why This Matters for India
For founders in Bangalore and Hyderabad building AI/ML applications, increased data center operational costs in Mumbai could translate directly to higher cloud infrastructure bills.
The Take
Maharashtra's discom secured short-term revenue, but the state just made itself significantly less attractive for the next wave of data center investment. Expect other states like Tamil Nadu or Uttar Pradesh to quickly capitalize on this policy misstep.
