LICAP Wind Turbine UPS Retrofit Solutions

LICAP Technologies has partnered with Windurance LLC to develop an ultracapacitor retrofit solution to replace the existing battery-based energy storage and charger system in GE 30Nm & 20Nm wind turbine pitch battery boxes. It is designed as a “drop in” replacement not requiring any modification to the pitch control system box or operating system. The ultracapacitor modules and capacitor charger unit (CCU) are common across the different pitch box iterations with only harness, bracket & mounting accommodations.
