Alvin J. Coleman & Son has filed a Mechanics Lien in the State of New Hampshire for the amount of $3,490,781. The Lien was filed against Cianbro Corporation, Groton Wind LLC, Iberdrola Renewables LLC, Iberdrola Energy Projects Inc, Yankee Forest Limited Liability Company and others. The full document can be accessed by clicking on the link(s) at the bottom of this page.

This wind energy lease agreement was negotiated between Iberdrola Renewables (operating as Heartland Wind LLC) and landowners in Livingston County, Illinois. The agreement was accepted into the public record by the County zoning board.

Editor's note: This short document prepared by personnel at the Wind Application Engineering Group of GE Energy provides some insight into the risks of ice throw. The content of this document confirms that ice fragments can be thrown large distances from the turbines.

This short GE Energy document explains the risk of ice build-up on the turbines and any mitigation. Note, the document acknowledges the risk of ice-shedding as well as ice-throw. An excerpt is included below. The full document can be accessed by clicking on the link.

Here is a reprint of an email about ice throw at Green Mountain Power's Searsburg wind energy facility in Searsburg Vermont. The email was written by John Zimmerman to an American Wind Energy Association listserv in 2000. Mr. Zimmerman managed the development of the Searsburg facility

This short paper prepared by Professor Terry Matilsky, Department of Physics and Astronomy at Rutgers University, explains how ice or other debris flung from a turbine blade can travel significant distances.

The Idaho House of Representatives is considering a bill that places a moratorium on "certain industrial wind farms and wind turbines for a time certain and to provide for an update to the Idaho Energy Plan". The full bill can be accessed by clicking on the links at the bottom of this page.

Idaho Power, a utility in the State of Idaho, is raising concerns over the impacts of wind generation on electricity costs and grid reliability. The utility ran this advertisement recently in an effort to educate the public on how integration of too much wind can degrade the power system and raise costs.

In this thesis the meteorological effects of a large-scale (9000 km2) offshore wind farm in the North Sea were simulated using the MM5 mesoscale model. The wind farm was simulated by introducing a higher roughness length (0.5 m) in the area of the wind farm. The meteorological effects were examined by comparing model runs with and without wind farm. Turbulent kinetic energy, cloud formation, precipitation and wind speed reduction were studied. Two case studies with westerly flows were performed. The first case study begins at 00 UTC July 1st 2001 and ends at 18 UTC July 3rd 2001. The second is from 00 UTC October 2nd 1999 to 18 UTC October 4th 1999.
