India's power sector faces critical evening supply crunch, HSBC warns

India's power generation sector is confronting a significant bottleneck during evening peak hours, with coal availability at thermal plants reaching precarious levels, according to analysis by HSBC. As of late September, coal stocks at power generation facilities had fallen to less than eight days of supply, a concerning decline from already strained inventory positions recorded in August.

The depletion of coal reserves has left approximately 40 percent of thermal power plants operating below their preferred inventory thresholds, exacerbating supply vulnerabilities during the crucial evening demand period when consumption peaks across the country. This vulnerability highlights a structural mismatch between India's baseload power generation capacity and the timing of consumer demand patterns.

Energy analysts view the recurring pressure on evening supply as a critical challenge for India's power infrastructure. The tightness in coal availability reflects broader supply chain constraints, including transportation bottlenecks and seasonal factors affecting pit-head stocks in major mining regions.

Experts have pointed to accelerated renewable energy capacity additions as essential to addressing the sector's evening supply pressures. By diversifying India's generation portfolio beyond thermal sources, the power sector could better manage demand fluctuations and reduce dependence on finite coal reserves during peak consumption hours. State utilities and central generating stations are consequently facing intensified pressure to fast-track renewable energy integration into their operational grids.
