SEEM is a good first step towards organized markets for renewables
Energy Imbalance Market (EIM) in the west is a work in progress that started in 2014. SEEM is a good first step for southeast utilities to coordinate in 2021. Transmission Owners (TOs) in the Midwest, power pool participants in New England and the Mid-Atlantic area took this step almost 20 years ago.
In the last two decades, what has changed is the energy transformation towards more fossil-free generation and more distributed energy resources. Part of the market improvements in well-established markets is due to the carbon-free nature of resources both on the supply and demand side.
