A second wind power farm will be constructed by Pacific Power close by the original Marengo facility near Dayton, Washington. The Marengo II Wind Farm will provide a further capacity of 71MW from 39 Vestas V80 wind turbines adding to the 140MW capacity that went on-line in August 2007.

This now gives the company roughly 210MW, making it the highest owner / operator of wind energy in the Pacific Northwest.

The Marengo II Wind Farm has been developed by RES America Developments Inc., a subsidiary of RES Americas, Inc. As well as supplying the wind turbines Vestas Americas will also be providing the service and maintenance of the turbines for four years.

Situated on 4,300 acres of agricultural land, the Marengo II project will not take up a significant proportion of the site allowing the fields to continue to be used for their primary agricultural purposes.

The project is due to be completed in June 2008.

The following PacificCorp / Pacific Power projects are currently either under construction or have been announced:

  • Marengo II, a 70.2-megawatt project near Dayton, Wash. Targeted for completion by June 2008.
  • Glenrock Wind Energy Project, a recently announced 99-megawatt project proposed at a site that includes a reclaimed surface coal mine in Wyoming. Construction will begin once necessary permits and approvals are in place, with completion targeted by the end of 2008.
  • Seven Mile Hill Wind Energy Project, a recently announced 99-megawatt project proposed in Wyoming. Construction will begin once necessary permits and approvals are in place, with completion targeted by the end of 2008.
