NERC assesses Clean Power Plan

The North American Electric Reliability Corporation completed an assessment on the potential risks to reliability resulting from the proposed Environmental Protection Agency’s Clean Power Plan. NERC’s assessment modeled scenarios focused on evaluating generation and transmission adequacy and potential reliability impacts.

The generation mix in the United States is going through a fundamental change. Policy considerations, such as the proposed CPP, impact and accelerate this transition. The goal of NERC’s assessment – Potential Reliability Impacts of EPA’s Proposed Clean Power Plan: Phase I – is to call attention to potential areas of concern for reliability and identify challenges that, if addressed, could ease the transition and allow for both environmental and reliability goals to be achieved.

NERC’s reliability-centered assessment consists of a three-part scenario analysis focused on resource and transmission adequacy and a review of existing studies by key reliability authorities. These key scenarios serve as a snapshot-in-time and were designed to provide benchmarks and guidance about the potential reliability aspects of implementation of the proposed CPP rule.
