U.S. report: Windmills fool radar

Defense officials say large, industrial wind turbines such as those proposed for Nantucket Sound can interfere with military radar systems if built in the radar's line of sight, according to a report released yesterday. Based on the report's conclusions, the officials have asked for more analysis about whether the proposed 130-turbine Cape Wind project would interfere with an Air Force radar station in Sagamore. The 62-page report, prepared for Congress by the Office of the Director of Defense Research and Engineering, specifically concludes that previous analysis of the effects on the PAVE PAWS radar station were ''overly simplified and technically flawed.'' The report calls for a more comprehensive study ''on an expedited basis.''

DOD report says wind farms will affect military readiness

MILWAUKEE - Large turbines generating electricity in a radar line of sight can harm the ability of air defense radars to detect and track aircraft or other aerial objects, the U.S. Department of Defense said Thursday in a new study. The only way to make sure that U.S. forces can perform their air defense missions is to avoid putting the wind turbines in the line of sight of the radars, said the report submitted to the Senate and House Armed Services committees. Efforts have started to find other ways but they "require further development and validation" before they can be used, given that some turbines with rotating blades reach 500 feet high, the report said. "The numbers, height and rotation of these wind turbines present technical challenges to the effectiveness of radar systems that must be carefully evaluated on a case-by-case basis to ensure acceptable military readiness is maintained," the report said.

Second wind farm project halted

The wind has been taken right out of a second wind energy project in the Thumb Area. Last month, Michigan’s first wind farm near Ubly was put on hold until next year. Now a smaller wind energy project in the Laker School District near Pigeon has been shut down by DTE Energy. The utility company says safety is the reason, but others disagree.

Invenergy Wind backs letter to Bush, White House

BROWNSVILLE -- It isn't over until it's over. Horicon Marsh Systems Advocates vows to continue fighting the approved $250 million wind farm planned for construction near the Horicon National Wildlife Refuge. In a recent development, Invenergy Wind LLC agrees with statements in a letter that 36 members of Congress sent to President George W. Bush and White House Council on Environmental Quality Chairman James L. Connaughton concerning wind energy and the Department of Defense study, said Neil Palmer, public affairs consultant for the Chicago-based developer. "We are very pleased to see the congressional delegation taking these positions and that three of them are from Wisconsin," he said. "While we have apparently been cleared on this issue in regard to the Forward project we feel that it's important that the DOD complete the study and if there are issues that it provide a description of how to address them."

Invenergy Wind to reassess $250 million project

BROWNSVILLE - Invenergy Wind LLC will re-evaluate its entire $250 million project after the Federal Aviation Administration recently issued hazard determination permits for 80 of its 133 turbine sites, according to Neil Palmer, public affairs consultant for the Chicago-based developer. He said Invenergy Wind plans to obtain pricing updates on turbines, equipment and construction as well as establish a schedule after nearly a year-long delay while the Department of Defense studied the effect wind turbines would have on military radar. "Once we get through that we'll have a better definition of when we'll start building but we don't know that today," Palmer said. He said the DOD, which doesn't have the authority to issue permits for wind turbines, asked the FAA to grant them until the DOD concludes its study.

FAA green-lights wind power plans - One project still faces lawsuit by opponents

Two Wisconsin wind power projects that were stalled by concerns that rotating turbines would interfere with military radar have received the go-ahead from the Federal Aviation Administration. Among them is one of the largest wind farms on the drawing board in Wisconsin: the Forward Wind Energy Center in Fond du Lac and Dodge counties. The Forward project, being developed by Invenergy of Chicago, was moving toward construction this year when it ran into a roadblock of opposition. Permits have been issued for both the Forward project, a 133-turbine development near the Horicon Marsh, as well as the Butler Ridge wind farm in Dodge County, said Bruce Beard, the FAA manager in Texas responsible for the office that issues permits.

Defense Department Misses Wind Farm Litigation Deadline

The U.S. Department of Defense (DOD) announced last week that it would miss a legal deadline in a suit that alleges the department is preventing wind farm construction across the nation. The department had until August 28 to file their response to the Sierra Club’s claim that it has created a virtual moratorium on the construction of new wind power plants by failing to complete a study of windmills’ impact on radar by Congressionally-mandated.

Air radar tilts with windmills: FIRE ISLAND: Electric generation could interfere with airport system.

A Chugach Electric idea to put giant, electricity-producing windmills on Fire Island is giving its neighbor, Ted Stevens Anchorage International Airport, a case of bad vibes. Radar experts recently found that electromagnetic waves from the proposed 33-windmill project would be so strong they would warp the signal of the airport's main air traffic control radar. On top of that, the sheer size of the windmills, whose blade tips could reach 400 feet in the air, would also physically block the signal of another key radar already on Fire Island.

Radar may hamper wind

SIOUX FALLS (AP) — Developers and officials hope that three wind farm projects in the works for South Dakota will go forward despite military officials’ concerns that turbines might interfere with radar.
