Clean Power Plan Implementation: A State, Power Company, and NGO Dialogue

March 10, 2015

The Georgetown Climate Center hosted its fifth dialogue among states, power companies, and NGOs recently to explore options for compliance under the Clean Power Plan, which will be finalized this summer.

Participants at the March 10 meeting reviewed key findings from recent modeling efforts and discussed different approaches that states could take to develop compliance plans. The agenda focused on opportunities, in either a rate- or mass-based context, for states to develop individual state plans that would leave open the option of interstate trading.

Previous convenings include:

An agenda from the most recent dialogue and a list of participants follows.




Welcome and Overview

  • Vicki Arroyo, Executive Director, Georgetown Climate Center
  • A. Stanley Meiburg, Acting Deputy Administrator, Environmental Protection Agency

Session 1—Key Insights from Recent Modeling Efforts
In this session, participants involved in modeling efforts discussed key findings across their analyses, such as: the impacts of regional cooperation on compliance costs; the implications of implementing a mass-based approach versus a rate-based approach; and the potential for emission leakage depending on compliance approaches.

Session 2—Discussion of a Rate-Based State Plan Model and Options for Interstate Crediting
Participants discussed a rate-based state plan approach that would allow for interstate trading of compliance credits. The discussion addressed options and considerations for how to determine the emission value of interstate credits, such as renewable energy or energy efficiency credits, and how an interstate rate-based crediting model could be advanced. 

Session 3—Discussion of a Mass-Based State Plan Model with Optional Interstate Trading
Participants discussed a mass-based state plan approach that would allow the state—or potentially affected sources in the state—the option of participating in an interstate trading market. This included discussion of what common elements individual state programs would need to include in order to allow participation in a centralized system, what centralized infrastructure is required, and what other guidance or support would be required.

Session 4—Cross-Cutting Issues
This session focused on the cross-cutting considerations that arise with both rate-based and mass-based programs, including: interactions between rate- and mass-based programs, the role of existing REC markets, and what potential national default rules or assumptions could address these issues.
