The Environmental Protection Agency’s (EPA’s) Clean Power Plan (CPP) is feasible in its ultimate goals, but getting there will take a lot of work and some rethinking of how the targets are achieved

Implementation of the Environmental Protection Agency’s (EPA’s) proposed Clean Power Plan (CPP) could change the use of the U.S. coal-fired generating fleet from baseload to seasonal peaking—and pose grave implications for plant economics and operating feasibility, the North American Electric Reliability Corp. (NERC) suggests in new special assessment.   The new report is the second […]

The U.S. energy infrastructure needs not just substantial investment for the future but also considerable rethinking about its role and functions in order to be positioned to deal with a rapidly changing energy landscape and evolving threats from cyber attack and climate change.
