HOMER Grid 1.1

A Utility is an organization that supplies electricity to customers. Examples of utilities in the US are Pacific Gas & Electric, Xcel Energy, ConEdison. A utility designs several tariffs to cover different types of services and customers. So a utility could have different tariffs for residential and commercial customers. Each tariff is a list of rate charges. Each rate describes a particular service. Example of rates are consumption rates for summer peak periods, fixed charges, adjustment charges etc.
