This paper describes the economic and technical justification for applying motor-driven compressors powered by on-site generated electricity. This application is unique in the gas pipeline industry and can be employed only under special conditions. The governing conditions are discussed and the alternatives that were considered are presented. The electrical expertise required for the project was contributed by the major equipment supplier, and the scope of this effort is presented. The equipment has been in operation for more than 14 consecutive months, so that reliable operating costs and experience can also be considered.
