Abstract

The present disclosure relates to a self-powered utility delivery system that includes a regulator that decreases a pressure of the utility flowing through the self-powered utility delivery system while producing electrical energy as a result of pressure regulation. Additionally, the self-powered utility delivery system includes an electronic utility meter that monitors a quantity (e.g., volume) of utility that flows through the self-powered utility delivery system and toward a consumer.

Claims
