About

The Neutron Storage project is a proposed 104.36 MW battery energy storage system located in McLennan County, Texas. The project, developed by Neutron Storage, is interconnected within the ERCOT region and entered the ERCOT interconnection queue as ERCOT-26INR0252 on September 8, 2023. Its proposed commercial operation date is April 29, 2028, and its interconnection agreement status is currently in the Facility Study phase.

The proposed project consists entirely of battery storage, with a total capacity of 104.36 MW. The point of interconnection is the Tap 345kV 13405 Trading House - 68090 Sam Switch. The project is currently listed as active within the ERCOT interconnection queue.
