Wind Power in Iowa: Lower Rates, Good Jobs

Opponents of expanding renewable energy often claim that new, safe and clean electricity is all very nice but it just costs too much. Let’s look at the data. The Energy Information Administration of the U.S. Department of Energy keeps statistics on retail electric rates by state and for the nation as a whole. The graph below[i] compares the average retail rates (residential, commercial, industrial) in Iowa to the U.S. as a whole starting in 1998 when Iowa began to produce significant amounts of wind electricity. While there are many reasons why a particular state’s electric rates are high or low it is certainly fair to say that our rank as the leader in per-capita wind electricity production (24.5 percent of all electricity in 2011)[ii] has not caused our rates to shoot up dramatically. Even though Iowa produces seven times as much wind power as the U.S. average, its rates continue to be about 2.5 cents per kilowatt hour below the national average.

Any discussion of prices for electricity must be qualified since the amount of wind electricity produced is not the same as the amount consumed in the state. States around Iowa have requirements that a percentage of electricity sold be from renewable energy. Iowa also has such a requirement and ours was the first in the nation, a fact the governor tends to emphasize, and the requirement was met long ago. Some wind electricity is certainly exported. Thus, while data on wind electricity consumption would be helpful, information is unavailable on what portion of electricity from each fuel source serves retail load and what is sold on the wholesale market. It should also be pointed out that selling at the wholesale level has some benefit to Iowa ratepayers.
