Oregon council to decide Sept. 18 on 415-MW, gas-fired project

The Oregon Energy Facility Siting Council at its Sept. 18 meeting will consider whether to approve a Site Certificate for the proposed Perennial Wind Chaser Station, a natural gas-fired plant with a capacity of 415 MW to be located near Hermiston.

The contested case aspect of this docket was closed on July 21. The applicant for this is Perennial-WindChaser LLC, a wholly-owned subsidiary of Perennial Power Holdings Inc., which is a wholly-owned subsidiary of Sumitomo Corp. and Sumitomo Corporation of America.

Perennial-WindChaser proposes to construct and operate up to four General Electric LMS100 (or equivalent) natural gas-fired combustion turbine generators in simple cycle configuration, producing up to 415 MW. Each turbine would be equipped with intercooler heat exchanger, electrical generator, selective catalytic reduction unit, catalytic oxidation unit, and stack. The applicant proposes to burn only natural gas, and each generating unit would be connected to a common cooling tower.

Perennial proposes to operate the station no more than 4,400 hours per year at full load, with an expected 500 startups and shutdowns each year, for a total of of 4,736 hours. As the name implies, this project is designed for quick ramping capabilities to provide capacity to fill in the gaps for highly variable wind farm output in the region.

Incidentally, the Oregon Department of Environmental Quality is taking public comment until Oct. 8 on the Perennial-WindChaser proposed air quality permit.

Two wind projects are also up for consideration at the Sept. 18 siting council meeting:

  • The council will consider the applicant’s request for a stay of the contested case for the Saddle Butte Wind Park. Pursuant to the hearing officer’s certification, the council will consider whether to grant a stay in the contested case proceedings and, if granted, the appropriate length of such a stay. Saddle Butte Wind LLC proposes to build and operate a 399-MW wind facility consisting of up to 133 turbines. At the request of the applicant, the Oregon Department of Energy has suspended work on the Site Certificate application, effective May 27. Prior to the suspension of work, the contested case proceeding on this matter was ongoing. Saddle Butte Wind is a wholly-owned subsidiary of Columbia Wind LLC, which is a wholly-owned subsidiary of Caithness Corp.
  • The council will consider a request to appoint a hearing officer for the 500-MW Wheatridge Wind Energy Facility. The applicant proposes to construct and operate a wind facility with three principal components: Wheatridge West; Wheatridge East; and an intraconnection corridor connecting them. The applicant proposes up to 292 wind turbines. The department determined the application for Site Certificate complete on July 1. The applicant submitted a filed application on July 13. The department is currently drafting the draft proposed order, to be issued in 2016. The applicant is Wheatridge Wind Energy LLC, a subsidiary of Swaggart Wind Power LLC.
