When I last posted on the potential impact of the Utility MACT rule on electric system reliability, I swore I was done with the subject. I knew then it was probably a mistake. Yesterday, FERC announced that it has issued a White Paper on how it will respond to requests by generators to EPA for an extension of time to comply under the Utility MACT rule. Since FERC has invited comments on the White Paper,… More

As readers of this blog know, the impact of EPA air rules, including in particular the Utility MACT rule, on the reliability of the nation’s electric grid has been the subject of much speculation. Last week, the Congressional Research Service weighed in, with the exciting headline: EPA’s Utility MACT: Will the Lights Go Out?” Of course, notwithstanding the sexy title, the CRS conclusion can be summarized pretty simply: the MACT rule will not cause the lights to go out. Money quote:

although the rule may lead to the retirement or derating of some facilities,… More

On Wednesday, EPA promulgated the final Utility MACT rule. I doubt that anyone reading this blog isn’t already aware of the big news.

As seems frequently to be the case with EPA rules, this one, weighing in at 2.4MB and 1,117 pages, cannot easily be summarized here. In fact, the rule is so complicated – and controversial – that EPA had to generate four separate fact sheets to summarize the rule and its impacts: (1) Costs and Benefits (or,… More

Yesterday, the North American Electric Reliability Corporation, or NERC, released its 2011 Long-Term Reliability Assessment. The NERC report identified environmental regulations as one “of the greatest risks” to reliability. Much of the focus of the concern was on EPA’s MACT rule for hazardous air pollutants and its 316(b) rule for cooling water intake structures. While expressing uncertainty about these not-yet finalized rules, the NERC report took an extremely cautious approach,… More
