sourceThe Southeast Oklahoma Pumped Storage project is a proposed 1232 MW battery storage development by Apex Energy Solutions, LLC, located in Lamar County, Texas. The project, identified as ERCOT-30INR0002 in the ERCOT interconnection queue, entered the queue on August 5, 2022, and has a proposed commercial operation date of January 1, 2030. Its interconnection status is currently in the Facility Study phase.
The proposed project consists entirely of "Other Storage" technology. Recent news coverage indicates regulatory interest in the project.
