IP-605 is a proposed 240 MW solar and battery hybrid project located in Elmore County, Idaho. The development project, listed in the Idaho Power (IP) interconnection queue, is being developed by South Bennett Solar LLC. The project consists of 240 MW of solar capacity and an unspecified amount of battery storage.
The project entered the IP interconnection queue on May 27, 2021, with a proposed commercial operation date of December 1, 2024. The interconnection agreement (IA) for the project was executed on April 20, 2023. The point of interconnection is the RTSN 230kV Substation. The project's current status is listed as suspended.
