The Rosscommon Solar project is a proposed 91 MW solar generation facility in Lamar County, Texas. The project, being developed by Roscsol, LLC, is located within the ERCOT region and interconnected to the grid at the tap 138kV 1691 Valley Switch - 1776 Paris Switch. It entered the ERCOT interconnection queue as project ERCOT-23INR0211 on March 1, 2021, and has a proposed commercial operation date of April 19, 2027. The project's interconnection status is currently in the Facility Study phase.
The Rosscommon Solar project has been mentioned in recent news coverage related to the energy industry.
