Public utilities provide electric, gas, water or telephone service to customers in a specified area. Utilities have a duty to provide safe and adequate service on reasonable terms to anyone who lives within the service area on without discriminating between customers. Because most utilities operate in near monopolistic conditions, they can be heavily regulated by local, state, and federal authorities. Generally, the local and state agencies are called Public Service Commissions (PSC) or Public Utility Commissions (PUC). Municipal Utilities and Rural Electric Cooperatives may be unregulated though.
Aurora is the second largest city in Illinois, with a population of 171,782 (2008 est. ) and part of the Chicago metropolitan area. The city refers to itself as "The City of Lights" because it was one of the first cities in the United States to implement an all-electric street lighting system in 1881. Aurora officially adopted the nickname in 1908.
