Biden crackdown on power plants expected to speed shift away from coal

The Biden administration’s
crackdown on power plants’ planet-warming emissions will accelerate a shift
away from coal, and potentially speed the U.S.’s adoption of renewable energy
sources.
The administration this past week announced a new rule
that will require coal plants and new gas plants to install carbon-capture technology to mitigate 90
percent of their emissions — or find another way to achieve the equivalent
climate protections.
But
experts say that instead of trying to meet these requirements, more coal plants
may just retire — and some power companies may opt to invest in renewables over
keeping existing coal plants or putting costly carbon capture on new gas
ones.
“What we’ve seen, even without these rules, is that coal
generation is falling,” said Christopher Knittel, a professor of applied
economics at the Massachusetts Institute of Technology (MIT), noting that “the
writing’s kind of on the wall” because of fracking driving down natural gas
prices.
“But,” Knittel added, “these new rules will certainly push to
speed that transition up.”
The Environmental Protection Agency’s (EPA) analysis shows
that the rule could increase the amount of coal power that
comes offline between 2028 and 2035 by nearly 25 percent.
The agency projects that without the rule, 84 gigawatts of coal
power would have retired during that period. But under the rule, that number is
expected to jump to 104 gigawatts of power.
Research firm BloombergNEF reached similar findings for this decade.
Julia
Attwood, an industrial decarbonization specialist with the firm, estimated
that around 44 gigawatts of coal power were due to retire by the end of
2030 anyway, but the rule will cause an additional 30 to 40 gigawatts to go
offline during that period.
Attwood said BloombergNEF models an average coal plant as
being equivalent to about 0.65 gigawatts, so this would amount to around 46 to
62 additional plant closures during that period.
“A lot of coal plants are just going to be pushed to retirement
because of the expense of using [carbon capture and storage],” she said.
The new
rule received significant pushback from coal advocates, including workers,
industry members and Republicans.
Cecil Roberts, president of the
United Mine Workers of America union, said in a written statement that it
“looks to set the funeral date for thermal coal mining in America for 2032” —
the date by which coal plants will now be required to cut their emissions.
Roberts added that the rule will “threaten the livelihoods of
our members” and said the administration has been unsuccessful at replacing the
jobs lost by miners in the energy transition thus far.
“I
am not aware of a single dislocated coal miner who has been hired as a result
of legislation or other initiatives put in place over the last several years,”
he said.
Sen. Shelley Moore Capito (R-W.Va.),
meanwhile, said she would introduce legislation to challenge the rule.
“The administration has chosen to press ahead with its
unrealistic climate agenda that threatens access to affordable, reliable energy
for households and employers across the country,” Capito, the top Republican on
the Senate Environment and Public Works Committee, said in a written
statement.
“I
will be introducing a Congressional Review Act resolution of disapproval to
overturn the EPA’s job-killing regulations announced today,” she added.
In addition to driving the country further away from coal, the
rule may also speed up an ongoing shift toward renewable energy.
The EPA projects the rule will boost the amount of the country’s
power that is supplied by renewable energy by an additional 4 percent in 2030.
Its impact will taper off over the years, however, as renewables would also be
expected to grow under previous policies: In 2040, it is expected to result in
just 1 percent more renewable energy.
Attwood
of BloombergNEF said she believes the rule is good for renewables because it
will “free up some needed capacity on the grid that renewables can fill.”
Mark Thurber, associate director at Stanford University’s
Program on Energy and Sustainable Development, said that renewables’ reliance
on weather conditions means they may not be able to sub in for coal in many
cases.
“It’s kind of an apples and oranges comparison between
renewables and then on the other side, gas and coal, because of the
intermittency of those renewables,” Thurber said.
But
Attwood noted that the rule’s exclusion of existing gas plants from
the new requirements could keep some such plants online — mitigating
concerns about renewables not working when there’s no sun or wind.
Knittel from MIT also believes the rule will “delay the closure
of existing gas plants” because maintaining such plants will be cheaper
than building new gas ones with carbon capture.
The Biden administration initially proposed restricting
emissions from some existing gas plants under the rule but ultimately dropped
those provisions, saying it would pursue a separate rule for existing gas.
It may not have time to do so if Biden isn’t reelected in
November, however — and if former President Trump returns to the
White House, he is not expected to increase climate regulations on
power plants.
“The big uncertainty that really remains here is what happens
with existing gas plants,” Attwood said.
“If it’s the same administration, then the EPA will probably go
back to those gas plants and try to figure out a way to put emissions
restraints on them as well,” she added.
