Coal-fired power plants subject to EPA’s MATS rule can try a biological treatment option to remove mercury emissions from the environment.

Minnesota Power Finalizes Environmental Agreement with EPA

Minnesota Power, a utility division of ALLETE, reached a settlement agreement with the Environmental Protection Agency (EPA) and the Minnesota Pollution Control Agency that resolves alleged violations of the new source review provisions of the Clean Air Act. The agreement does not include any admission of wrongdoing on the part of the company Minnesota Power is one of many utility companies in the U.S. whose investments in electric generation facilities were reviewed as part of the EPA's Coal-Fired Power Plant Enforcement Initiative that began in 1999.

Nuclear At a Crossroads

Wind, nuclear, and gas resources must work together – not at cross-purposes.

Why the U.S. must maintain current levels of nuclear energy production to achieve carbon reduction goals.

Waiting for the Next Polar Vortex

How recent events could prove a harbinger of winters to come.

The winter of 2013-14 offered up a perfect storm of natural gas price spikes and threats to electric reliability. Expect more of the same.
