US power firms crank up dirty fuel usage to fight cold wave: Maguire

Power generators have increased output from highpolluting coal and oilfired power stations this year to assist fight an extended cold wave covering much of the country.

Coal-fired power production across the lower 48 states was the greatest considering that at least 2019 throughout Jan. 1-22, and up 6% from the exact same duration in 2015, information from LSEG shows.

Production from plants that burn fuel oil - used mainly as a. backup to gas-fired plants - soared 170% from the exact same days a. year ago to the greatest in three years.

Output from natural-gas-fired plants - the main power. source in the U.S. - declined by 2% from last year's record. levels, however is holding near the greatest production rate ever. for this time of year.

The broad swell in fossil-fuel-fired output came just as. big swathes of the nation got knocked by a prolonged bout of. below-normal temperatures, which forced power companies to lift. output from every available resource.

However the fossil boom also took place just as the second. administration of U.S. President Donald Trump swore to step up. output and use of nonrenewable fuel sources in U.S. energy production.

That raises the concern of whether power manufacturers now feel. they have a license to continue releasing high levels of fossil. fuels for power; or will they continue to build up tidy. generation capability and phase out fossil use over the long run?

COLD SNAP

Temperature readings across several parts of the United. States plunged well listed below regular for numerous days so far in. 2025.

Average recorded temperature levels throughout the Midwest, Atlantic. Coast, the Plains states and throughout the South all swooped. far below the long-term averages tape-recorded in those areas,. according to LSEG.

To fulfill the resulting increase in demand for heating, power. manufacturers throughout the country cranked production from all. offered sources from Jan. 1-22.

Nuclear reactor output climbed by 3.7% from the same. days in 2023 to 2.14 million megawatt hours and the highest. since 2020, while wind output climbed 1.5% to a record 1.2. million MWh.

Nevertheless, an almost 3% decrease in output from hydro plants -. due to an enduring dry spell in key locations - made sure that power. companies had to likewise lift production from fossil fuel facilities.

Coal-fired production was 2.5 million MWh throughout the Jan. 1-22 duration, compared to 2.3 million MWh the year before, while. fuel-oil-fired plants raised output to 44,420 MWh from just. 16,420 MWh over the same dates in 2023.

Gas-fired plants created 4.38 million MWh of power from. Jan. 1-22, down 2% from the year before.

Output from solar farms was 386,112 MWh over the first three. weeks of 2025, up 51% from the same dates in 2023.

In all, the temperature plunge across such a large swathe of. the nation for such a prolonged duration clearly required the. use of all power resources so far in 2025, consisting of the use of. a few of the highest-polluting plants in the country.

When temperatures go back to normal, power trackers will be. monitoring whether generation companies dial down fossil fuel use. again, or if the strong assistance for fossil fuels in the White. Home leads to a sustained rise in the burning of polluting. fuels throughout the U.S. generation system.
