Customer Success Story: U.S. Wind Farm Cuts O&M Costs, Reduces Number of Turbine Climbs with Maxwell’s Ultracapacitor Energy Storage Solution

| Jessica Baris, Communications Specialist and Copywriter

Iowa Lakes Electric Cooperative (ILEC) runs two wind projects, both rated at 10.5 megawatts. Since the turbines were commissioned in 2009, the wind farms have been a positive force in the local communities by supplying clean power for neighboring ethanol production facilities and providing economic support for landowners who host wind turbines.

But running a wind farm is no easy feat.

When battery component replacement for the turbines’ emergency pitch systems became a more frequent and costly task that required additional climbs per week, ILEC approached Maxwell Technologies to integrate its ultracapacitor-based retrofit solution for greater reliability and performance in the field.

"The batteries are the root issue here," says Al Zeitz, ILEC’s manager of renewable energy services. "A lot of the challenges that we have with these battery pitch systems is that there are a lot of associated faults with the components related to the batteries."

Once ILEC installed Maxwell’s ultracapacitor-based energy storage retrofit solution in the turbines’ emergency pitch control systems, the team experienced immediate results, including:

  • Reduced number of battery-related pitch faults
  • Significant drop in number of turbine climbs necessary to address battery system failures
  • Reduced operations and maintenance costs and component replacements
  • Streamlined system performance and reliability
  • Increased turbine uptime and availability

"Maxwell’s ultracapacitor retrofit solution and its longevity helps us toward our goal of extending the life of the wind turbines."
