AWEA Statement on Nebraska Wind Power Integration Study

13 de marzo de 2010

A groundbreaking study has found that Nebraska and the other states in the Southwest Power Pool (SPP) region can reliably obtain 40% of their electricity from wind energy.

A groundbreaking study has found that Nebraska and the other states in the Southwest Power Pool (SPP) region can reliably obtain 40% of their electricity from wind turbines, achieving major carbon emissions reductions and incurring only minor costs associated with operating the power system differently than it operates today.

The wind power integration study, funded by the National Renewable Energy Laboratory, examined how the power system would operate in scenarios in which 10%, 20%, and 40% of the electricity was supplied by wind energy in Nebraska and the SPP region, which includes all of Kansas and Oklahoma, most of Nebraska, and parts of New Mexico, Texas, Louisiana, Missouri, Mississippi and Arkansas. A 40% wind energy penetration is one of the highest levels studied thus far, in the U.S. or anywhere in the world.

Major carbon emission reductions were found in all scenarios, with CO2 emissions dropping by over 25 million tons per year in moving from the 10% wind scenario to the 40% wind scenario.

The study also found that the cost of operating the power system differently to accommodate wind energy was modest, although exact integration costs varied depending on the methodology used to account for the costs. One method found costs ranging from $1.39 per megawatt-hour (MWh) of wind energy in the 10% wind case up to $1.68 per MWh of wind energy in the 40% case.
