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.
Portage is a city in Kalamazoo County in the U.S. state of Michigan. The population was 44,897 at the 2000 census. Portage is adjacent to the southern boundary of the City of Kalamazoo. The city was incorporated from the entirety of the former Portage Township on December 31, 1963. There are two public high schools in Portage, Portage Central and Portage Northern. The pharmaceutical company Pfizer also has operations located there, which in recent years has caused much controversy due to layoffs. Portage is known for its extensive network of historical parks and trails used for cycling, walking, canoeing, and other recreational activities. Since the creation of the Portage Bikeway system in 1989, the trails have expanded to over 50 miles (80 km), over five times as long as the city’s expressways. Portage is also home to the Kalamazoo Air Zoo.
