The Carty Generating Station is a 450-megawatt, combined-cycle natural gas-fueled electric generating power plant. The facility was previously approved to consist of up to two 450-megawatt, combined-cycle electric generating turbines (Unit 1 and Unit 2). Unit 1 was constructed and put in service in July 2016. The construction deadline for Unit 2 has passed and therefore, Unit 2 and all related or supporting facilities that were previously approved but not built are no longer authorized, including the 18-mile, 500-kilovolt transmission line to the Slatt Substation in Gilliam County. PGE has requested EFSC approval of Amendment 1 to construct and operate a 50-megawatt solar electric facility.

Under Review/Operating. In August 2016, PGE submitted a request to amend the site certificate to extend the construction deadline for the previously approved Unit 2 natural gas power generating facility, add a Unit 3 natural gas power facility, and add a 50-megawatt solar electric facility. In May 2017, prior to an EFSC decision on that amendment request, PGE suspended the review. On February 20, 2018, ODOE received a revised amendment request from PGE. The request includes only the solar electric facility on approximately 300 acres.

As the original amendment request was received by ODOE in 2016, the request is being processed under the EFSC rules and administrative procedures that existed at that time. The Department has issued public notice and is currently accepting public comments on the amendment request. Comments must be submitted in writing to the Department and must be received by April 6, 2018 at 5 p.m. Please see the public notice for additional information regarding submittal of comments.​
