EPA issued this document in 2015 as a resource for state and local air agencies preparing National Ambient Air Quality Standards (NAAQS) State Implementation Plans (SIPs).

This discussion paper will help state and local air agencies understand options for:

• Identifying on-the-books EE/RE policies and estimating the incremental electricity savings of these policies;
• Developing a methodology for projecting a jurisdiction’s energy demand both with and without the incremental electricity savings; and
• Estimating the change in power sector emissions attributable to the incremental electricity savings

This methodology was developed to illustrate how EE/RE policies could be accounted for in the context of NAAQS SIPs, as required in Section 110 of the Clean Air Act.
