Project overview

Many North Carolina municipal utilities run diesel and natural-gas generators — typically 500 kW to 3 MW — to cut peak demand charges.

We provide the protection settings, commissioning, and startup support these cities need to run those units safely, with the protective relay acting as backup protection and control alongside each engine controller.
