A building energy system includes equipment operable to consume, store, or discharge energy resources purchased from a utility supplier to satisfy energy loads and a controller configured to allocate the energy resources across the equipment over a predict...

A system for and of charging a capacitor can be used in a failsafe device. A voltage level is sensed at the capacitor, and a current is provided to the capacitor until a threshold voltage level is reached. The threshold voltage level is above a target volt...
