The Ministry of Power has directed 112 captive coal-fired plants with at least 50MW capacity to run at full output from October 1 to December 31, 2026. This emergency measure aims to meet rising demand. Industrial firms like Tata Steel and Vedanta must now sell surplus power to exchanges and report operational data, which may affect their energy cost structures and margins.
The Ministry of Power has issued a directive for 112 captive coal-based power plants, each with an installed capacity of 50 megawatts or more, to operate at maximum output starting October 1, 2026. This mandate, which invokes emergency powers under the Electricity Act, is scheduled to remain in effect through December 31, 2026. The government implemented this move to ensure grid stability as it anticipates a sharp rise in power demand during the final quarter of the year, partly due to weather-related factors.
The order directly affects the operations of several large industrial conglomerates. Companies such as Vedanta, Tata Steel, Hindalco Industries, JSW Steel, and UltraTech Cement, which typically run these captive plants primarily for their own manufacturing requirements, must now adjust their output to meet the government's target. Beyond just increasing production, these companies are required to sell any surplus electricity on national power exchanges rather than withholding supply.
This directive introduces additional operational complexity for these industrial firms. Operators are now required to provide granular, weekly data to the Central Electricity Authority. These reports must cover essential metrics, including internal power consumption, total electricity sold on the exchange, available capacity, and current coal stock levels. Consistent monitoring by the regulator is expected to ensure that companies adhere to the production targets throughout the three-month period.
For investors, this shift in operational focus requires attention to how it may impact company financials. Managing power plants at peak capacity often involves higher variable costs, particularly for fuel. If companies must procure additional coal at market rates to meet this mandate, and if the price of electricity on the exchanges fluctuates, there could be pressure on the profit margins of these captive generation units. Investors may want to track whether the revenue from surplus power sales adequately covers the operational costs associated with running these plants at full load.
Separately, the government has extended the emergency operational order for Tata Power’s imported coal-based plant located in Mundra, Gujarat, which will also continue to operate at full status until the end of the year. This extension underscores the broader regulatory priority of preventing regional power shortages during the high-demand cycle. Moving forward, the key factor for investors to monitor will be any management commentary regarding the impact of these mandatory generation levels on working capital and operating margins in the energy-intensive segments of these businesses.
