The proposed IP-556 project is a 30 MW solar and battery hybrid development located in Grant County, Oregon. The project, developed by Prairie City PV1, LLC, consists of 30 MW of solar capacity. It is interconnected to the Idaho Power Company system via the QUTZ_x0013_WJDY 138kV Substation.
The project entered the Idaho Power (IP) interconnection queue on April 30, 2019, with a proposed commercial operation date of November 30, 2021. An Interconnection Agreement (IA) was executed on August 4, 2021, though the project's current status is listed as suspended.
