Electric Utilities

Diamond Bar Electric Utilities are the most likely to function as a hybrid of monopoly and competitive services. Only one system for transmitting and delivering electricity to customers is feasible in a given service area such as Los Angeles County, CA.

However, the electricity in the Diamond Bar electric grid may come from numerous suppliers.

Sewer Utilities
