All SPP interconnection data follows the standardized response format with core fields for project identification, capacity, technology, and status.
Data Updates: SPP queue data is updated based on Southwest Power Pool’s Generation Interconnection queue reports.
Wind Capital: SPP territory includes some of the best wind resources in North America, particularly in Kansas, Oklahoma, and the Texas Panhandle. Wind projects dominate the interconnection queue.
