Managing Principal Sue Tierney and Coauthors Update Report on Ensuring Electric System Reliability

November 21, 2011

The electric industry is well-positioned to maintain the reliability of the bulk electric system as it transitions to cleaner, more efficient generating systems, say Managing Principal Susan F. Tierney and consultants from M.J. Bradley & Associates LLC, in a new report addressing the means by which the industry can comply with clean air emissions regulations being proposed by the U.S. Environmental Protection Agency (EPA).

Their report, “Ensuring a Clean, Modern Electric Generating Fleet While Maintaining Electric System Reliability: Fall 2011 Update,” is the third in a series of white papers focusing on the reliability implications of two EPA rules affecting the electric power sector: the Transport Rule and the Utility Toxics Rule. The first report, published in August 2010, concluded that the electric industry is well-positioned to comply with EPA’s proposed air regulations without threatening electric system reliability. The summer 2011 update supplemented the original analysis in light of new information and reaffirmed the prior report’s central conclusion.

This fall 2011 update focuses on the many tools that are available for ensuring electric reliability as companies comply with the EPA rules by installing modern pollution control systems, utilizing allowances, or retiring portions of the power-generation fleet that are uneconomic to retrofit. “With the proper planning, communication, and use of available tools outlined in this paper, the American public can have clean air and a reliable electric power system,” the authors conclude.
