Iowa’s wind energy leadership has created significant economic, community and environmental benefits for the state, but there is huge potential for additional wind energy. Thanks in part to continued advocacy for wind energy growth, utility companies are taking notice and investing in clean energy.
In May, we welcomed announcements from Alliant Energy to add 200 MW of wind and by MidAmerican Energy to build 552 MW of wind. When MidAmerican filed its official proposal – Wind X – with the Iowa Utilities Board, we joined with the Environmental Law and Policy Center (ELPC) to intervene and file testimony in support of the proposal.
Iowa ended 2014 with over 5,700 MW of installed wind energy that accounts for 28.5% of the state’s electrical generation, the highest of any state. Iowa’s wind energy potential is over 570,000 MW, and recent national studies indicate that 20,000 MW could be developed by 2030, and 37,000 to 46,000 MW by 2050. Wind X is an important step to reaching these goals, meeting more of our energy needs with clean energy, and reducing our reliance on coal.
Despite its leadership in wind energy, coal still accounts for the largest share of MidAmerican’s electricity. Importing coal costs MidAmerican’s customers approximately $285M annually, and the state of Iowa $590M annually. Wind X will directly reduce coal use and the associated costs, as well as cut emissions of carbon and other pollutants.
By doing so, Wind X will help MidAmerican – and Iowa – prepare to comply with the proposed Clean Power Plan, the first-ever standard to reduce carbon pollution – our country’s largest source of carbon pollution – from existing power plants. The Clean Power Plan establishes state-specific carbon reduction goals based on each state’s energy portfolio. Based on 2012 carbon pollution levels, Iowa’s proposed cut in carbon pollution from power plants is 16%. As a wind energy leader, Iowa is well-positioned to meet its goal.
Recent wind projects have already helped reduce MidAmerican’s rate of carbon emission from 1,168 lbs/MWh to 1,030 lbs/MWh. Wind X would further reduce the rate to 940 lbs/MWh or even lower. Thanks to its wind leadership, MidAmerican is ahead of schedule and can help the state – or even other states – meet these targets.
In addition to expressing our support for Wind X, our testimony encouraged MidAmerican to more thoroughly consider adding solar energy when it builds its next clean energy project. We reviewed MidAmerican data showing that its energy demand peaks occur in the summer and during the day, typically between the hours of noon and 6 pm. A typical solar array in Iowa can be expected to produce very well during such times, meaning solar can help MidAmerican meet energy needs when demand is at its highest.
We will continue to advocate, shape and voice our support for Wind X and projects like it, and build a broad base of support for the Clean Power Plan and a strong implementation plan that will benefit Iowa’s economy and environment.
