Wind power in Iowa
Encyclopedia
Iowa
is a leading U.S. state in wind power
generation of electricity. Wind power in Iowa has 3,675 megawatts (MW) of capacity in 2011, second only to Texas. Wind power accounted for almost 20 percent of the state’s electricity generation in the first quarter of 2011. Since Iowa adopted a renewable energy standard in 1983, the wind power industry has generated almost $5 billion in investment. The 444 MW Rolling Hills Wind Farm in southwestern Iowa is due to be completed in late 2011.
reported that the installed wind power capacity in Iowa was 3670 MW. Only Texas
has a higher amount of installed wind power capacity.
Wind power installations increased by 879 MW from a year earlier. In the prior year, 2008, over 1500 MW of wind power generation was installed. Also in 2008, Iowa overtook the historical leader in wind power, California
.
In 2010 and in 2009, Iowa led the U.S. in the percentage of electrical power generated by wind, at 15.4 percent and 14.2 percent. This was up from 7.7 percent in 2008, as there was a large increase in the installed capacity in 2008. Some of the wind power generated electricity is sold to utility companies in nearby states, such as Wisconsin
, and Illinois
.
Wind farms are most prevalent in the north and west portion of Iowa. Wind maps show the winds in these areas to be stronger on average, making them better suited for the development of wind energy.
Average wind speeds are not consistent from month to month. Wind maps show wind speeds are on average strongest from November through April, peaking in March. August is the month with the weakest average wind speeds. Estimates by the National Renewable Energy Laboratory (NREL) indicate Iowa has potentially 570,700 Megawatts of wind power using large turbines mounted on 80 meter towers. This places Iowa within the top 10 states in terms of wind energy potential.
The average capacity factor
of Iowa wind farms has been estimated as 33.3% by a wind industry consultant. Several of the newer projects are the large 440 MW Rolling Hills project near Massena
, the Elk Wind Farm near Greely, and Gamesa's Pomeroy project north of Pomeroy
. All were constructed in 2011.
According to the Iowa Office of Energy Independence, lack of transmission line capacity is beginning to restrict further growth of wind farms in the state. A report from the NREL acknowledges that this is a major hurdle to increased wind power development in the U.S. One proposal for expanding the transmission capacity in the Upper Midwest
is the Green Power Express. A high voltage DC line that would transmit power from near Sioux City
to the Chicago area has also been proposed.
In May 2010, a plan to have 50% of the electricity generated in Iowa come from wind power was announced. Of the wind generated electricity, 40% would be used in state and 60% would be sold to out of state customers.
by TPI Composites and in Fort Madison
by Siemens. Turbines are manufactured in Cedar Rapids
by Clipper Windpower
and in West Branch
by Acciona
. Towers are also manufactured in Newton by Trinity Structural Towers. Companies manufacturing other parts for wind turbines are located in Iowa as well.
In addition to manufacturing, various companies support the development of wind power projects.
In late September 2007, Siemens Power Generation
celebrated the grand opening of its new wind turbine blade factory in Fort Madison, on the banks of the Mississippi River. The 311000 square feet (28,892.8 m²) factory is expected to produce 600 wind turbine blades each year and should employ 260 people by year's end. The facility manufactures 148 feet (45.1 m)-long, 12-ton blades for the company's 2.3-MW wind turbines installed in the United States.
Clipper Windpower manufactures its 2.5 MW Liberty wind turbine at its Cedar Rapids location. This model is being used in the Endeavor project in northwest Iowa and in the huge Titan Wind Project
in South Dakota.
The Iowa Office of Energy Independence (OEI) is tasked with determining policy and setting goals towards renewable energy production. The office seeks to coordinate efforts between industry, community leaders, state and local government, and educational institutions to achieve energy policy goals.
The Spirit, Endeavor, Buena Vista, Lost Lakes, and Crosswind Energy wind farms are all located upon the Coteau des Prairies
, a slightly elevated area that results in the windiest locations in Minnesota
and Iowa. Coteau des Prairies is sometimes referred to as Buffalo Ridge
, which is actually a specific ridge within the area, mostly in Minnesota.
Power from the Iowa Lakes Superior and Iowa Lakes Lakota projects is used by ethanol fuel
plants in their respective communities. This marks the first use of wind power being used to supply energy to produce another renewable energy source.
It has been announced that two large wind farms to be built by Mid-American Energy have
been approved by the Iowa Utilities Board. The two wind farms would have a combined capacity of 1000 MW. Mid-American Energy is owned by Warren Buffet's Berkshire Hathaway
company.
