Unseasonal rains, surplus provide ship real-time energy costs crashing on IEX

On Sunday, RTM costs hovered round zero following in a single day showers and thunderstorms in and across the Delhi-NCR area. On Thursday, the worth for a single RTM block had dropped to an all-time low of two paise per unit earlier than recovering. On a year-on-year foundation, common RTM energy costs have declined 22% to ₹3.69 per unit attributable to decrease electrical energy consumption.

“Unseasonal rains and thunderstorms in May stored temperatures low, leading to a 2% year-on-year decline in electrical energy consumption throughout May 1–21, 2025. At the identical time, elevated hydro, wind, and thermal technology created surplus availability, bringing down Real-Time Market costs to a mean of ₹3.69/unit—a 22% YoY drop,” mentioned Rohit Bajaj, joint managing director, Indian Energy Exchange.

The RTM permits energy discoms and different entities to purchase and promote electrical energy for rapid necessities, with bodily supply going down one hour after market closure. It accounts for practically 30% of the entire electrical energy traded on the alternate.

Lower temperatures have decreased the usage of cooling home equipment comparable to air conditioners. Peak energy demand throughout the nation fell to 215 GW on Saturday, 24 May, in comparison with 220 GW or extra recorded earlier within the month.

While the RTM is just not giant sufficient to immediately affect family electrical energy payments instantly, sustained low costs could affect tariffs within the subsequent fiscal yr.

“Distribution companies (discoms) are required to tell the electrical energy regulator about their projected expenditure on energy purchases from electrical energy exchanges. If they find yourself spending lower than budgeted, the underspending is mirrored in annual filings. This might immediate the regulator to revise tariffs downward within the subsequent tariff order, probably passing on the profit to customers,” mentioned an govt at a discom. However, he added, the RTM stays comparatively small in scale, so its affect on general energy prices and tariffs remains to be restricted.

Power mills, in the meantime, are sometimes compelled to provide electrical energy even when market costs are low. Withholding provide might imply lacking alternatives to promote in upcoming time blocks when costs could also be increased. Moreover, failing to ship energy after submitting bids can entice penalties below market rules.

Thermal energy crops additionally face technical constraints in ramping technology up or down. Frequent output fluctuations can cut back effectivity and put on out gear. To keep away from such dangers, mills usually proceed supplying energy at a loss to take care of steady operations. The current rains have additionally boosted hydropower technology, placing further downward strain on costs.

Bajaj famous that RTM members are utilizing the low-price surroundings to their benefit by substituting costlier thermal technology with RTM purchases throughout photo voltaic hours, serving to optimize prices and boosting market volumes.

“These traits underscore the rising significance of the RTM in giving discoms, open entry customers, and industrial and industrial (C&I) customers the flexibleness to acquire energy in close to real-time and handle prices amid dynamic supply-demand situations,” he mentioned.

In the close to time period, costs are anticipated to stay subdued attributable to forecasts of continued rainfall and thunderstorms in Delhi-NCR and different areas. The India Meteorological Department (IMD) has additionally projected an above-normal monsoon this yr.
