In 2015, 26.1 percent of the electricity generated in Nebraska was sold out of state. This represented an increase of 12.8% from 2014. In 2014, 23.4 percent of the electricity generated in Nebraska was sold out of state. This was the second consecutive year to nearly double (a 43.8–percent increase) exports from the previous year. In 2013, electricity exports nearly doubled from 2012–offsetting the decrease in 2012 when exports were cut nearly in half (47.2 percent) to 3,390 million kilowatthours from 6,419 million kilowatthours in 2011. Exports fell with the increase in retail sales and the decrease in net generation from 2011. The report, Nebraska's Annual Electricity Net Generation by Energy Source and by Producer, shows increases in generation by natural gas and wind energy in 2012. These increases were not high enough to offset the decreases in generation by the other fuels.
