Entered ERCOT queue and began Facility Study phase
The Scorpius Solar project is a proposed 500 MW solar generation facility located in Milam County, Texas. The project, developed by Ben Milam Solar 4, is currently active in the ERCOT interconnection queue as entry ERCOT-26INR0609, with a queue entry date of December 16, 2024. The proposed commercial operation date is June 14, 2029, and the project's interconnection agreement status is currently in the Facility Study phase.
The proposed project consists of 500 MW of solar photovoltaic generation. It is planned to interconnect at the 3377 LTPSW 345KV point of interconnection. The Scorpius Solar project has appeared in recent news coverage regarding renewable energy development in Texas.
