How Dependable Is Coal Really? Not Nearly as Much as the Coal Lobby Wants You to Believe

Frozen piles of coal outside Green Bay, Wisconsin powerplant are being relocated to aid waterfront development.

The coal lobby is working overtime to convince the public that coal is the last trustworthy grown-up in the room. Their latest Utility Dive op-ed leans on a single planning metric, ELCC, as if it were a divine seal of reliability. It is not. And the way they use it is so misleading it borders on performance art.

Here is the part they hope you will not look up: ELCC, or Effective Load Carrying Capability, is not a reliability score. It does not measure whether a coal plant will freeze, fail, or choke during a winter storm. It does not measure forced-outage rates. It does not measure fuel-supply risk. It does not measure cold-weather performance.

ELCC answers one narrow planning question:

"How much does this resource reduce blackout risk during the grid's highest-stress hours?"

That is it. It is a capacity accreditation tool, a modeling input, not a verdict on dependability. Treating ELCC as proof that coal is "more reliable" is like treating your car's insurance premium as proof it will start on a January morning.

And when you look at what actually happens during real stress events, the coal lobby's narrative collapses.

Coal's real-world performance is the part they never mention

Coal's ELCC did not save it during Winter Storm Elliott

PJM's own post-mortem shows that coal and gas units caused the overwhelming majority of unexpected outages. Not wind. Not solar. Not batteries. Coal's "high ELCC" did not keep its units from tripping offline when the grid needed them most.

The cost case leans on one consultant study and ignores the rest

The op-ed leans on a fossil-funded model while ignoring independent data from EIA, NREL, and Lazard that all point the same direction: in most regions, it is cheaper to replace coal with new wind or solar than to keep burning fuel in an aging boiler. That is why utilities are retiring coal: the economics are brutal.

Cherry-picking one storm to smear renewables is not analysis

If you need to zoom in on a single weather event to make your point, you do not have a point. Across multiple storms, coal's performance is inconsistent at best and catastrophic at worst.

Fuel-supply risk is coal's Achilles' heel

Frozen coal piles, rail delays, and mechanical failures in fuel-handling systems are not edge cases; they are recurring risks. NERC has been warning about this for years. The op-ed simply airbrushes it out.

Coal is not the only firming resource left

Modern grids rely on storage, flexible gas, demand response, hydro, geothermal, and interregional transmission. Coal is not the backbone of reliability anymore. It is the legacy asset utilities are trying to retire without blowing up their balance sheets.

The pollution ledger the op-ed will not show you

There is no mention of CO2, particulates, mercury, or SO2. When an argument requires you to hide the externalities, it is not an argument. It is a brochure.

Bottom line

The coal lobby's claims are rebuttable because they are built on a misuse of ELCC, selective data, and a refusal to engage with coal's actual performance during extreme weather. When you stop staring at the spreadsheet and start looking at what happens on the ground, the truth is unavoidable:

Coal is not the dependable workhorse the industry wants you to believe it is. It is the resource that keeps failing when the grid is under the most stress.
