The REGEN Energy power controller based on the principles of swarm energy was first covered in the December 2007 Newsletter (Issue 5.4) with an update in the March 2012 issue of Zygote Quarterly. REGEN Energy and Carrier recently announced that "Carrier will offer REGEN Energy's patented Swarm Energy Management solutions to customers through Carrier's distribution network" as part of a strategy to integrate air conditioners with energy management systems. The GreenTechMedia article Regen Energy and Carrier Partner for Rooftop AC Efficiency provides information on cost, performance and sales of the swarm controllers.
