Under the agreement, AMP-Trillium, the joint venture between AMP Americas and Trillium CNG, will build seven public fueling stations between August 2013 and early 2014 and lease new CNG trucks that will travel more than 13.2 million miles per year, servicing routes throughout Texas.

The stations, which will be built in Waco, Amarillo, Harrold, Sweetwater, Weatherford, Kerrville and Midland, will initially fuel forty new Class-8 Kenworth and Peterbilt CNG sleeper trucks, a number that will double over the course of the agreement.

The deal structured by AMP Americas features beneficial contract terms for fleets operated by Western Dairy Transport and Reynolds Transport, establishing the two as “first-movers” by operating two of the largest 12-liter commercial CNG fleets in the US.

AMP Americas, LLC, a Chicago-based energy company focused on displacing liquid fuels with CNG, builds and owns CNG fueling stations for long-haul truck fleets and finances leases for CNG trucks. AMP operates the largest US renewable natural-gas plant that produces fuel from cow manure.

Trillium CNG, a business unit of Integrys Energy Group (NYSE:TEG), is a leading provider of CNG to fleets, and also offers complete facility design, construction, operation and maintenance services.
