The primary objective of this project is to analyze the benefits of different balancing approaches with increasing levels of interregional cooperation. Scenarios were defined, modeled and investigated to address production variability and uncertainty and the associated balancing of large quantities of wind power in SPP and delivery to energy markets in the western regions of SERC. The study evaluates the scheduling/balancing challenges associated with delivery of sufficient wind generation from within the SPP footprint to support 20% energy from renewable resources across the SPP, Entergy (EES), Southern Company (SoCo), and the Tennessee Valley Authority (TVA) balancing areas for the year 2022. The project team worked closely with staff from each of these companies to develop a model of the possible generation fleets within each BA. Based on the 2022 generation plans identified, specific wind generation sites within the SPP footprint were identified to yield sufficient energy output to allow each of the 4 BAs to meet the net renewable energy requirement beyond the renewable energy from the base generation fleet. As the effort required for transmission planning for increased amounts of wind was outside the scope of the project, transmission constraints were ignored and a transportation model was used. The Eastern Interconnect wind generation data set developed by the National Renewable Energy Laboratory (NREL) was utilized for identifying specific wind plants with SPP for both internal SPP consumption and for delivery to the SERC BAs.
