The Carty Generating Station is a 450 megawatt, combined-cycle natural gas-fueled electric generating power plant, and includes a not-yet-constructed 50 megawatt solar PV electric power generating unit.
Under Review/Operating. On February 28, 2020, the Department received Request for Amendment 2 (RFA2) to the Carty Generating Station Site Certificate as well as an Amendment Determination Request (ADR) requesting the proposed amendment be processed under the “Type B" review process.RFA2 seeks approval incorporate of shared infrastructure and existing facilities (shared by the Boardman Coal Plant and Carty Generating Station) into the Carty Generating Station site certificate; modify the Site Boundary of the Carty Generating Station; and construction new infrastructure including but not limited to a new sewer line, a new backup water pipeline, new potable water line, and a new office and warehouse space. The proposed amendment would increase the facility site boundary from 1,581 acres to 4,611 acres (an increase of approximately 3,030 acres) by almost entirely incorporating existing areas within the existing site boundary of the boundary from the Boardman Coal Facility only. The amendment is related to the pending shutdown of the Boardman Coal Facility, which is scheduled to occur by end of 2020. The Boardman Coal facility and the Carty Generating Station are located adjacent to each other.

The Department issued public notice of receipt of pRFA5 and the Type B Review request on March 13, 2020. On May 29, 2020, the Department determined that a Type B Review for pRFA2 was justified, and its evaluation can be found below. Following review and determination of pRFA2 completeness, a Draft Proposed Order (DPO) and notice of opportunity to provide public comments on the amendment request and DPO will be issued.
