The Evening Cliff: A Structural Vulnerability
India’s energy system is undergoing a critical test. The rapid growth of solar power, which supplies around 30% of electricity during peak daylight, has helped manage record demand. However, this has created a new vulnerability: the 'evening cliff.' As solar output vanishes at sunset, and millions of people turn on cooling systems, the grid faces extreme pressure. It must instantly switch to thermal and gas power plants, which are operating at their maximum capacity to prevent widespread blackouts.
Company Operations Amid High Demand
Companies like NTPC Ltd and Tata Power are navigating this challenging environment. NTPC, trading with a P/E ratio between 13.9x and 15.6x, is crucial for providing the thermal power needed to cover evening shortages. However, its high debt-to-EBITDA ratio of about 4.9x limits its ability to fund major infrastructure upgrades quickly. Tata Power, with a higher P/E multiple of 26x–32x, is valued for its focus on renewable energy and distribution networks. Despite their different strategies, both firms face issues with aging distribution equipment that struggles under sustained heat, leading to local power interruptions even when the national grid has sufficient capacity.
