Entered ERCOT queue in Facility Study phase
The proposed Watermelon 3 Energy Storage project is a 102.1 MW hybrid battery energy storage system located in Dallas County, Texas. The project, developed by Tempus Power Management LLC, is interconnected within the Electric Reliability Council of Texas (ERCOT) region under queue ID ERCOT-27INR0459. The project entered the interconnection queue on January 13, 2025, with a proposed commercial operation date of March 1, 2029.
The interconnection point of the project is a tap on the 2427 WATMLL_W5 to 2432 TRICRN1_5 345kV line ckt 1, approximately 1.6 miles from 2427 WATMLL_W5. The project's interconnection status is currently active within the ERCOT queue. Recent news coverage has discussed the development project.
