Coal availability and stock position for thermal power plants; flexible operation regulations and grid support measures
Coal availability and stock position for thermal power plants; flexible operation regulations and grid support measures
- The Ministry of Power said coal-based generation continues to provide the bulk of electricity supply and that coal stock at thermal plants is adequate for near-term demand.
- The Central Electricity Authority has notified flexible-operation regulations for coal-based thermal generating units to support renewable integration.
- Coal supply to thermal power plants is being reviewed daily through coordination among the Ministry of Power, the Ministry of Railways, and the Ministry of Coal.
- Battery Energy Storage Systems and Pumped Storage Projects are being used to store surplus electricity during solar hours and release it during non-solar hours.
India’s power system still depends heavily on coal-based generation, but the Ministry of Power has linked that dependence to grid flexibility, fuel logistics, and storage-backed balancing. The official position is that thermal plants remain essential for reliability, while the electricity system is being adjusted to accommodate more renewable generation and peak-demand stress.
What the Ministry of Power said
According to the Ministry of Power, coal-based generation capacity in India is about 230.8 GW, and coal including lignite contributed 69.54% of electricity supplied from April to June 2026. The Ministry of Power also said that maximum generation from such plants reached about 188.8 GW during non-solar peak-demand hours.
UPSC may frame India’s power-sector challenge as an energy-security and energy-transition question: coal-based thermal capacity still anchors supply, while the electricity system increasingly depends on flexible-operation norms, storage, and coordinated fuel logistics to absorb variable renewable energy and meet peak demand.
