While coal makes a comeback, reduced supplies stoke fears over electrical grids

ARCA MAX:

Coal, a pariah fuel for climate activists, has made a quiet comeback this year in the post-lockdown economic resurgence. Coal stockpiles at power plants are getting so low that the regional electric grid operator, PJM Interconnection, has taken steps to prevent a system collapse this winter similar to Texas earlier this year.

PJM, based near Valley Forge, this month imposed new rules on power plants in 13 states and the District of Columbia to make sure electricity generators do not run short of fuel during a cold snap. The rules could force some coal generators to curtail operations to build up emergency reserves, increasing power prices already on the rise.

Demand for coal has jumped in response to rising natural gas prices, even though coal emits more toxic and greenhouse gases per kilowatt hour generated than rival fuels. Coal-fired power plants have struggled to replenish stockpiles because the energy sector is facing the same kind of supply chain challenges that have slowed deliveries of many goods and commodities.

“Our top priority at PJM is ensuring a reliable electric grid,” said Michael Bryson, PJM’s senior vice president of operations. “We are especially concerned about coal supply chain issues and inventory levels heading into the winter.”

The resurgence of coal power, even amid a worldwide push to promote clean energy and decarbonize electricity production, demonstrates that fossil fuels still remain very much in the energy mix, coal advocates say.

Policymakers need to recognize coal as “part of an all-the-above energy strategy for the foreseeable future because the coal fleet supports grid reliability and resilience, helps keep electricity prices affordable, provides fuel security, and serves as an insurance policy when other electricity sources are not available or are too expensive,” said Michelle Bloodworth, chief executive of America’s Power, a trade group for the coal industry.
