Bill Impacts of the Clean Power Plan

Energy Foundation
Project completed February 2016

Synapse modeled various Clean Power Plan compliance options to determine how big an impact strong energy efficiency policies can have on the achievability and affordability of complying with EPA’s rule. Using the Synapse Clean Power Plan Toolkit, a collection of purpose-built in-house tools and commercial models, including the National Renewable Energy Laboratory’s Regional Energy Deployment System (ReEDS) model, Synapse examined the comparative cost of state implementation plans that maximize available energy efficiency strategies versus a future in which states are not Clean Power Plan‐compliant. Synapse modeled and found savings for each of the 48 continental U.S. states. 

The results, updated in the factsheet and accompanying report below, show that if states comply using strategies that encourage cost‐effective energy efficiency, households can save on electricity bills.

Synapse held a series of public webinars on this topic:
