Entered ERCOT interconnection queue at Facility Study stage
The Watermelon 4 Energy Storage project is a proposed 102.1 MW hybrid development project located in Dallas County, Texas. The project, developed by Tempus Power Management LLC, consists of battery energy storage and other unspecified technologies. It is listed in the ERCOT interconnection queue as entry ERCOT-27INR0460, with a queue entry date of January 13, 2025, and a proposed commercial operation date of March 1, 2029.
The point of interconnection (POI) is on the 345kV line ckt 1 between substations 2427 WATMLL_W5 345.00 and 2432 TRICRN1_5 345.00. The project's interconnection status is currently listed as active.
