The Tariff Analysis Project (T.A.P.), is a comprehensive data warehouse of utility tariffs combined with a variety of query and analytical tools.

T.A.P. contains a growing library of hundreds of tariffs, from over a hundred utilities, for residential, commercial-industrial, agricultural and public sector customers. A generic data model has been developed to concisely represent all varieties of tariff structures, capturing seasonal charges, time-of-use rates, and complex block structures.
