Oregon council mulls changes for Summit Ridge Wind Farm project

The Oregon Energy Facility Siting Council is taking comment until April 18 on a Feb. 11 request for approval of Amendment #2 to the Summit Ridge Wind Farm Site Certificate.

The application is from the certificate holder, LotusWorks-Summit Ridge I LLC. The requested amendment seeks to: transfer the existing Site Certificate from LotusWorks-Summit Ridge I to Summit Ridge Wind Holdings LLC; extend the construction start and completion deadlines by two years; and add a 3 MW turbine option.

In 2011, LotusWorks-Summit Ridge I obtained a certificate for the Summit Ridge Wind Farm, a wind generation facility with electrical capacity of up to 200 MW. The council approved an amendment to the site certificate in August 2015 to extend the construction deadlines, reduce the maximum number of wind turbines, reduce the capacity to 194.4 MW, increase maximum wind turbine hub height, increase maximum blade tip height, decrease the blade tip clearance, and reduce the project site boundary.

The current request would transfer ownership of the site certificate, extend the construction deadlines, and add a 3 MW turbine option that, if selected, would reduce the total electrical capacity to 192 MW and reduce the total number of wind turbines from a maximum of 72 to a maximum of 64. The 3.0-MW turbine option would include larger generators, a reduced hub height, and a greater rotor diameter. The overall height of the turbines would decrease by approximately two meters, and the minimum blade tip clearance would decrease from 23 to 18 meters above ground.

The project would include related and supporting facilities, including a power collection system, collector substation, approximately seven miles of 230-kV transmission line to connect to the Bonneville Power Administration transmission system, meteorological towers, an operation and maintenance building, and approximately 25 miles of access roads.

The Summit Ridge Wind Farm would be located on approximately 11,000 acres of privately owned land in northeastern Wasco County, 17 miles southeast of The Dalles and eight miles east of Dufur.

After reviewing the proposed amendment and any comments received, the council staff will prepare a Proposed Order that will recommend to the council the approval, modification, or denial of the amendment request. Upon the release of the Proposed Order, the agency will issue a public notice for a 30-day period for comments or requests for a contested case hearing.
