First municipal food waste-to-renewable energy facility to connect to power grid in urban setting in U.S.

Columbia Biogas signs agreement with PacifiCorp to connect to grid

Portland, Ore.—Columbia Biogas has entered into a Small Generator Interconnection Agreement with PacifiCorp Transmission for interconnection to PacifiCorp's Killingsworth substation in Northeast Portland. Columbia Biogas will convert commercial food waste to renewable power from its plant on Columbia Boulevard in Northeast Portland. Under the agreement, Columbia Biogas will deliver electrical power to the PacifiCorp system.

PacifiCorp serves 1.7 million retail electric customers in six western states and operates as Pacific Power in Oregon, Washington and California. "This is another landmark agreement with PacifiCorp," said John McKinney, president of Columbia Biogas. "We believe we are one of the first municipal food waste-to-energy projects in the United States which is located within an urban industrial setting. We value our partnership with PacifiCorp and look forward to celebrating groundbreaking this fall and beginning commercial operations in late 2013."

"On behalf of our customers, we are pleased with what this new agreement with Columbia Biogas does for renewable energy generation," said Pat Egan, vice president of customer and community affairs for Pacific Power, the local utility operation of PacifiCorp. "We appreciate the opportunity to work on this deal together with Columbia Biogas, to bring cost-effective renewable energy to our customers."

The renewable energy facility in Northeast Portland will convert commercial food waste from the metro area into multiple green products including renewable energy, water and naturally derived fertilizer. Columbia Biogas will receive food waste from commercial and industrial sources such as grocery stores, restaurants, food distributors as well as food and beverage manufacturers. A process of anaerobic digestion in sealed tanks will degrade organic matter to produce methane-rich biogas.

In May, Columbia Biogas signed a Power Purchase Agreement with PacifiCorp for the energy output of its plant. The facility is expected to initially generate 3 megawatts (MW) of electrical power which is equivalent to the electrical needs of as many as 3,000 average homes. Ultimately, Columbia Biogas intends to increase its electrical production to 5 MW.

The Columbia Biogas facility will be located in Northeast Portland at 6849 NE Columbia Boulevard near Interstate-205. The site is centrally located in an industrial zoned area and provides convenient access for the delivery of food waste. In 2010, the Oregon Department of Environmental Quality and Metro approved permits for the facility.

Introducing RockIt Smart Slide

Introducing RockIt Smart Slide - the ultimate solution for fast and easy installation of the rail-less RockIt racking system on composition shingle roofs. Smart Slide conforms to UL 441 and TAS 100 (A)-95 for wind and wind-driven rain, providing a super-strong watertight seal that is achieved through compression, in most cases without the need for additional sealant. The waterproofing sealant is embedded deep into the granules of the shingle, thanks to the integrated flexible foam layer that provides cushioning. This ensures a secure fit that conforms to any architectural-style shingle. With UltraGrip Technologyâ„¢, you can rely on a secure installation, as it absorbs the movement created by thermal expansion and contraction. The pre-installed sealing pads are compatible with all composition shingle roofs, making it the ideal choice, even in ambient temperatures as low as 5 degrees.
