On July 1, 2004, Tierra Energy completed the acquisition of a 50% ownership interest in the Glenns Ferry Cogeneration Facility located in Glenns Ferry, Idaho. The Glenns Ferry project is a 10 MW natural gas-fired cogeneration power plant which entered commercial operations in late 1996.

The facility utilizes proven Solar Mars gas turbine technology operating in combined cycle with a Murray-Tuthill steam turbine and a Deltac heat recovery steam generator.

The Glenns Ferry project sells electrical energy under a long-term Power Purchase Agreement with Idaho Power Company. Natural gas is purchased from Talisman Energy and the Facility holds firm gas transportation with Northwest Pipeline. Fuel management services are provided by Amerada Hess. Thermal energy is sold under a long-term Thermal Sales Agreement with Idaho Fresh-Pak, a manufacturer of dehydrated potato products.

Tierra Energy provides asset management, contract compliance, tax, insurance and accounting support to the project and a subsidiary of Black Hills Corporation is the plant operator.
