India May Direct Coal Plants to Operate at Lower Loads to Create Space for Solar Power

In a significant step toward integrating more renewable energy into the national grid, the Indian government is considering a directive that would require coal-fired power plants to operate at lower loads during peak solar generation hours. The move aims to ensure smoother absorption of the country’s rapidly growing solar output, officials familiar with the discussions said.

Under the proposal, coal plants would be mandated to reduce their Plant Load Factor (PLF) during daytime when solar power generation is at its highest. This would help avoid curtailment of renewable energy and maintain grid stability as India works toward its ambitious clean-energy goals.

The Central Electricity Authority (CEA) has been evaluating operational patterns and is expected to develop a framework that balances solar integration with the need for reliable baseload power. While coal power remains essential for meeting nighttime and peak-demand requirements, authorities believe more flexible operation of thermal units is now necessary.

Energy analysts say the shift represents a major structural transition in India’s power sector, where renewable energy capacity has surged to meet climate commitments and energy security needs. However, power producers caution that operating at lower loads could affect efficiency and increase maintenance costs for older coal plants.

Despite these challenges, the government appears committed to expanding renewable penetration while optimizing thermal operations. A formal guideline is expected after consultations with state utilities, grid operators, and industry stakeholders.
