SEPTA has signed a three-year $316,560 contract with a Boston company to provide energy consulting services to the regional transit agency.

SourceOne, a subsidiary of Veolia Energy North America, will advise SEPTA on strategies for the purchase and management of all SEPTA utilities, including natural gas, water and sewer, electricity, heating oil, and propane, said Frank Gormley, SEPTA's operating budget director. SourceOne will also evaluate the viability of alternative energy projects. SEPTA spends $56 million a year on utilities, including $42 million for power to propel trains, subways and trolleys.

Veolia Energy is the owner of the Grays Ferry cogeneration plant and the Center City district steam system.
