Primer on Structure of the Electric Power System and Implications for Federal Carbon Pollution Standards for Existing Power Plants

May 23, 2014

As states develop plans in response to EPA limits that will reduce carbon pollution from existing power plants, coordination with state and regional electric power system regulators is important.  While the language of section 111(d) of the Clean Air Act contemplates state programs, electricity flows across state lines and is managed through multi-state electricity markets that do not align with state borders.

This document provides a brief primer on how the electric power system functions and the role played by different entities in its operation and oversight. It also identifies key issues related to the structure of the electricity system that will be relevant for states to consider as they develop plans to comply with the new EPA standard.
