As President Obama looks to implement strict rules on carbon emissions, coal-powered electrical generation is on the chopping block. For those worried about climate change, coal is a convenient target. Unfortunately, a plan by the Environmental Protection Agency to shutter hundreds of domestic, coal-fired power plants has been hastily thrown together, with no confirmed alternatives for steady, reliable power generation.

What’s at stake is “grid reliability” — whether supply exists to meet the current, massive U.S. demand for electricity. For much of the country, the EPA’s mandate is troubling because, right now, roughly 40 percent of electricity in the United States comes from coal-fired generation.

The importance of coal in generating electricity was demonstrated very clearly last winter when coal-fired plants worked overtime to heat homes and businesses during a deep freeze. In fact, American Electric Power, a major utility company, reported that 90 percent of its coal plants slated for retirement under pending EPA rules were running at full speed just to meet peak demand.

Despite record-setting production in the Marcellus Shale formation and elsewhere, natural gas simply can’t compensate for a shortage of coal plants. This is due in part to a lack of infrastructure to deliver gas where it’s needed. But more importantly, natural gas has already been prioritized for home use, not power generation.

A recent report from PJM Interconnection, the regional power transmission group for a dozen states (including Pennsylvania) and the District of Columbia, concluded that without coal plants there could be insufficient electricity to meet peak winter demand.

Under the EPA’s “Clean Power Plan,” consumers will undoubtedly pay higher electricity bills. But the more tragic problem is the possibility of widespread power outages during the coldest parts of winter.

These worrisome scenarios have so far been swept aside by the federal government. The shift away from coal is moving ahead with no regard for the consequences. And so, in light of the recent PJM report, the EPA’s regulatory plan amounts to very reckless toying with the nation’s power grid.

The truth is that there’s simply no way around the use of coal to help ensure affordable and reliable power in the current market. That’s why state utility commissions and regulators from 22 states have sent formal comments to the EPA expressing concerns that the Clean Power Plan will jeopardize reliable and affordable electricity. That’s why the U.S. needs a diversified power portfolio that includes coal in order to meet the nation’s electricity needs.

Those seeking to eliminate coal under the guise of improving the environment need to adopt a realistic plan. Modern coal-fired generators are cleaner now than they ever have been. And with technology under development today, even cleaner coal plants will soon be attainable. Any move away from coal that can add sufficient alternative sources of power generation will require many years to implement. Thus, it makes no sense for the EPA to rush ahead with a foolhardy plan that will effectively undermine the ability to generate reliable and affordable electricity in America.
