Wind Power | Marengo II Wind Farm
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.

We and friends visited the Marengo I/II windfarms last evening (3-Jul-09). Amazing view from the top. Not one of the turbines was generating any power. The power demand for the region was high as the weather was turning in temperature values near 100′F. As I have shown on our blog and with YouTube video (http://www.youtube.com/watch?v=NgKQlG2AT-k), the wind power is fickle and generally out of phase with demand(http://www.transmission.bpa.gov/Business/Operations/Wind/baltwg.aspx, http://kandg.org/WPBlogger/?paged=2). How can we expect to run 21st century society, industry, hospital intensive care units in this manner? The last 150 years showed how to use windmills effectively: pumped water storage for cattle troughs and railroad water tanks. Not direct ties to a grid. For the period July 01@9:00 to July 03@15:50, the maximum wind power for the entire northwest BPA grid was only 177MW compared to the unusable nameplate capacity of 2100MW.
