Oregon's Energy Facility Siting Council (EFSC) is to decide this month on a 39.6 MW expansion of FPL Energy's 261 MW Stateline wind project. The application, lodged just four months after completion of Stateline, will increase the project size to about 300 MW. FPL confirms it applied to EFSC to amend its site certificate, but refuses to confirm when or if the company will install the additional turbines this year. FPL is asking EFSC to approve an additional 60 Vestas 660 kW turbines south of the existing Stateline project and southwest of the 24.6 MW Vansycle Ridge project, which it completed in 1998. FPL's initial plans for the Stateline project, the second largest wind development in the US, included more than 450 Vestas turbines totalling 300 MW. Project planners were set to install 200 MW in Washington and 100 MW in Oregon until an environmental review discovered the presence of several colonies of endangered nocturnal ground squirrels (Windpower Monthly, August 2001). That forced the developer to downsize the project to 261 MW, but FPL has continued to say it will eventually fill out the wind farm to its original 300 MW size. Electricity generated by the new turbines will be transmitted via a 34.5 kV underground wire to a substation in Washington. FPL also proposes to construct two meteorological towers on private land now cultivated in wheat.
