Southeast Energy Exchange Market

Delivering more economic and clean energy to our customers.

SEEM is a unique and thoroughly new approach to enhancing the existing bilateral market. The new SEEM platform will facilitate sub-hourly, bilateral trading, allowing participants to buy and sell power close to the time the energy is consumed, utilizing available unreserved transmission. Participation in SEEM is open to other entities that meet the appropriate requirements.

SEEM is a 21st century solution designed for the incredible pace of change resulting from the electricity sector growing toward an ever-greener future. Southeastern electricity customers will see cost and environmental benefits as a result of the new platform that is set to become operational in the fourth quarter of 2022.

Founding members of SEEM include Associated Electric Cooperative, Dalton Utilities, Dominion Energy South Carolina, Duke Energy Carolinas, Duke Energy Progress, Georgia System Operations Corporation, Georgia Transmission Corporation, LG&E and KU Energy, MEAG Power, N.C. Municipal Power Agency No. 1, NCEMC, Oglethorpe Power Corp., PowerSouth, Santee Cooper, Southern Company and TVA.

The founding members represent nearly 20 entities in parts of 11 states with more than 160,000 MWs (summer capacity; winter capacity is nearly 180,000 MWs) across two time zones. These companies serve the energy needs of more than 32 million retail customers (roughly more than 50 million people).
