The Southeast Energy Exchange Market (SEEM) announced that it is operational, allowing participants to buy and sell power through its advanced SEEM platform.
SEEM serves electricity customers in the southeastern United States The new SEEM platform will facilitate automated, hourly trading and allow participants to buy and sell electricity in a timely manner as the energy is consumed, utilizing available unrestricted transmission. This advanced platform aims to improve energy trading volume, reduce fuel costs for customers, and Solar shutdown reduction. It shows how digital means can increase transparency and efficiency and thus use energy resources wisely, which makes perfect sense for making renewable energies like solar more competitive – and driving the energy transition.

Customer savings can be realized by selecting less expensive and more efficient generation resources to meet customer demand. When energy vendors find a use for their excess energy, those profits also benefit customers in return.
In terms of carbon footprint, a study estimated CO2 emission reductions for the SEEM region under operating conditions at 570,000 tons per year for the IRP Baseline Outlook and 790,000 tons for the Carbon-Constrained Outlook.
The SEEM platform will help customers save money and better integrate renewable resources while ensuring all customers across the region are delivering on the promise of renewable energy.
— said Noel Black, Southern Company’s senior vice president of governmental affairs.
With the addition of Duke Energy Florida, Seminole Electric Cooperative, Tampa Electric Company, and JEA in early 2023, SEEM’s footprint would have 23 units in portions of 12 states with more than 180,000 MW (summer capacity; winter capacity is nearly 200,000 MW) spread across two time zones. These companies serve the energy needs of more than 36 million retail customers (nearly 60 million people).
