India, May 7 -- In early 2026, India's power sector recorded a major milestone, passing the 52% mark in meeting installed capacity for non-fossil fuels. However, the share of actual generation from RE sources reached almost 30% in FY2024-25. While this is good news, the higher generation brings a distinct set of operational challenges.

The first phase was easier because of the initial gains from rapid capacity addition, declining costs, policy support and strong market momentum. And now, as RE penetration increases, the system must manage intermittency, demand mismatch and balancing requirements.

To decode the dynamics of RE issues, some elaboration is required. The challenges of higher RE installed capacity include underutilised grid i...
