GE this fall began pushing a new bit of software wizardry that it says will boost wind farm performance. Looks like E.On is biting.

GE said that the Germany-based energy giant would install PowerUp, described as a “customized software-enabled platform that increases a wind farm’s output by up to 5 percent,” at five wind farms. This adds up to 469 GE 1.5-77 wind turbines that E.On uses (through its Climate & Renewables division).

GE is suggesting that this is the equivalent of building as many as 19 new turbines of that size, but it’s going to have to prove that’s the case in order to make money off implementing PowerUp for E.On. That’s because this is an “outcomes-based” deal: The companies will measure the impact of PowerUp, and GE will get only a percentage of the gains the technology brings.

“The outcomes-based approach aligns well with our goals of providing cleaner, better energy at a more affordable price,” Steve Trenholm, chairman, E.ON North America, said in a statement. “Investment in wind energy has led to technological advancements like PowerUp that continue to make renewables more and more competitive with traditional forms of energy.”
