About Richardson Electronics The Richardson Electronics ULTRA3000® Pitch Energy Module (PEM) is an ultracapacitor-based plug and play replacement for batteries within GE wind turbine pitch systems and is compatible with all General Electric (GE)* 20 & 30 Nm pitch systems. Ultracapacitor-based energy storage solutions have significantly enhanced reliability in electric pitch control systems. Ultracapacitors, unlike batteries, have the ability to deliver quick bursts of power in a short time frame, an ideal function for emergency pitching in a wind turbine generator (WTG).
