The Stem Solar project is a proposed 200 MW solar generation facility in Swisher County, Texas. The project, developed by Innovative Solar 134, LLC, is located within the ERCOT region and interconnected to the tap 345kV 23914 Tule Canyon - 23912 Ogallala. It entered the ERCOT interconnection queue as queue ID ERCOT-24INR0003 on February 4, 2020, and has a proposed commercial operation date of August 26, 2025. Its interconnection status is currently in the Facility Study phase.
The Stem Solar project has been the subject of recent news coverage, with 13 articles published across industry, grid, deals, and development categories.
