The 3-megawatt turbines are already used abroad and North American customers are interested in buying them because they will make it feasible to build wind farms in less-windy places where smaller, 1.5 MW turbines will not work as well, she said. The larger rotor diameters mean less wind is necessary to turn the blades, Hazen said.
Between 17 and 27 wind towers are expected to go up south of Edgewood and west of Greeley. Steve Dryden is the owner of R-P-M Access, which will build and run the 41-megawatt facility.
The farm is completely operable, Witt said, but the problem lies in the transmission of energy from its location near Zearing to Ames. The farm will need to upgrade its transmission lines before the university will be able to meet its goal, Witt said.
Michael O'Sullivan of NextEra Energy, Iowa's second-largest producer of wind power, told the American Wind Energy Association meeting in Dallas this week: "Our product is too expensive relative to other options. Our competitive advantage has largely evaporated." The sudden rise of natural gas is credited with throwing wind energy into another of its periodic slowdowns. Iowa, with 2,300 megawatts of wind electricity generation, trails only Texas among the 50 states in wind capacity.
Wind turbines such as these could soon be built by the hundreds in Marshall County after recent passage of an ordinance regarding how they are taxed Tuesday. The turbines generate a clean, renewable electricity. Marshall County now has a new ordinance that should make wind farms a little easier to build in the county.
Transportation -- of both giant wind turbine parts and the electricity they eventually generate -- remains the biggest hurdle to continued growth of wind power, an Iowa utility official says. Neither an extensive network of farm roads in a state like Iowa nor the existing corridors of high-power electric lines match the expanding needs of wind farms.
The amendment alters maximum tower height from 100 feet under the previous ordinance to 65 feet for lots between 1 acre and 3 acres in size, 80 feet for lots between 3 acres and 7 acres in size, and 100 feet for lots larger than 7 acres in size. It also specifies than any earthen berm, terrace or retaining wall used to elevate the turbine be considered a part of the turbine itself.
TPI Composites announced Wednesday it is laying off more than half of its workers by cutting approximately 237 positions at the Newton wind blade manufacturing plant. The company said in a press release that the layoffs were part of a restructuring process to "meet current and future customer and market expectations."
A state economic development board today gave TPI a green light to go ahead with a proposal to build a new blade manufacturing plant in Sioux City, with members saying they believed the wind-energy company would hit its job-creation promises in Newton. ...State documents show the company has until July 30 to create 504 jobs in Newton.
A The wind blade manufacturer that's weighing construction of a plant in Sioux City said today it's unlikely it will meet the job-creation requirements for its plant in Newton by July. Arizona-based TPI Composites said it "continues to restructure its operations in Newton" and will reduce its workforce to 233. The company did not say how many workers would be cut in this latest round of layoffs.
A manufacturer of wind turbine blades is looking to bring a $38 million factory to Sioux City that would create 500 good-paying jobs. To land the large-scale project, the city and Woodbury County expect to construct the facility and then lease it back to the company, Arizona-based TPI Composites, according to documents filed Monday with the state of Iowa.
Today, state Rep. Tom McMillin of Michigan introduced a resolution (H.R. 277) urging his state's governor to withdraw Michigan from continued participation in the Midwestern Greenhouse Gas Reduction Accord (MGGRA), an agreement among the region's governors to reduce greenhouse gases through a regional cap-and-trade program. ...nearby participating states intend to introduce similar measures in their own legislatures.
On April 23, TPI announced it was laying off an undisclosed amount of temporary employees. ...The blade manufacturer for "green" wind turbines has an agreement with local government agencies that by the end of 2010 it will hire 500 employees in return for $4.8 million in grants it was previously awarded.
A proposed 14 percent increase from Alliant Energy for electrical rates would not only be a burden on some residential customers, but could affect expansion for local businesses. ...IPL representatives say they need the money to recover costs for "green" energy investments. The 14 percent raise - or $163 million - will fund expenses from Whispering Willow Wind Farm, a $468 million project, and major investments in distribution and transmission infrastructure.
If you're interested in wind energy and its implications for Iowa and the Midwest, best to keep an eye this week on a decision by the federal government about a wind project off the Atlantic coast opposite Massachusetts and Rhode Island.
While interest in generating wind energy has grown among Iowa's urban dwellers, many are finding their local zoning regulations make it hard or impossible to install one. 'Some are opening up to 60-foot heights, so you can put a residential turbine in place, but it's still a battle,' said Rob Hach with Anemometry Specialists Inc.
Aller, the top executive of Alliant subsidiary Interstate Power, also has to explain why his customers will pay as much as 50 percent more for power than fellow Iowans who are MidAmerican customers if the latest rate increase is approved by the Iowa Utilities Board.
The district may need to repair a wind turbine it owns at the Joice wind farm. The turbine, purchased in about 2005, "trips out" - turns off and on - frequently, Nugent said. "It trips out far more than it should be," he said. ...Engineers from Denmark are scheduled to come in the fall for annual maintenance, but the district may have to fly them in earlier than that, Nugent said.
The Walcott City Council is considering a wind energy ordinance that would cover the growing trend of roof-mounted turbines for residential or business use. The council passed the first of three readings Monday and will vote a second time April 19 after it gets answers to a few questions about heights from the city's zoning administrator.
The rate increase request, filed earlier this month by Alliant subsidiary Interstate Power & Light, includes a proposed 14 percent increase, or $163 million. Alliant wants to invest in expanding renewable energy and reducing emissions.
