MISO coal dispatch hits 3-year low in January

Coal-fired generation in the US' second-largest electricity grid dropped to a three-year low in January, even as overall power demand surged during an arctic cold front at month's end.

Generators in the Midcontinent Independent System Operator (MISO) dispatched an average of 583,745 MW/d of coal generation last month, a 10pc decrease from January 2025 and the lowest January level since 2023, the grid operator reported.

January's drop interrupted a pattern of year-on-year increases in MISO coal generation observed in all of 2025 and in December 2024.

MISO's overall generation increased slightly last month, rising to just under 1.99mn MW/d from 1.98mn MW/d in January 2025.

Coal dispatch picked up during the last week of January, but the fuel's share of the grid generation mix for the full month still slipped to 29pc from 33pc a year earlier. Coal's share of MISO's generation in January was also 1.3 percentage points lower than in December 2025.

Temperatures plunged at the end of last month as a large mass of arctic air moved across the central and eastern US, with parts of Missouri and Louisiana recording record-low temperatures. The higher overall generation supported an increase in use of fossil-fuel power, but generators leaned more heavily on natural gas in MISO last month.

Natural gas-fired generation in the region increased to 697,370MW/d last month, up from 619,073MW/d in January 2025. Gas accounted for 35pc of total generation in January, up from 31pc in January 2025.

MISO had nearly 1,467MW less available winter nameplate coal capacity as of the end of December 2025 than it did a year earlier, according to estimates from the US Energy Information Administration. At the same time, the amount of gas and renewable winter nameplate generating capacity in the grid climbed by roughly 2,746MW and 9,319MW, respectively. Solar accounted for more than two thirds of that additional renewable capacity.

MISO's nuclear and solar power generation increased in January from a year earlier. However, total renewable generation, including hydro, fell by 2.4pc to 413,204 MW/d last month. Wind generation decreased by 7.7pc to 327,794 MW/d, while hydro generation dropped by nearly 19pc to 21,218 MW/d. The combined share of the generation mix for renewables fell to 20.8pc from 21.4pc.
