Project Profile

Finley Buttes Cogeneration Project

Boardman, Oregon
End User(s):
PacifiCorp, Cascade Specialties
Utility, Food Products
Finley Buttes Regional Landfill
Landfill Size:
4 million tons waste-in-place (2001)
Project Type:
Combined Heat and Power (cogeneration) (2 reciprocating engines)
Project Size:
3.2 megawatts (MW) and 10 million British thermal units per hour (MMBtu/hr)
Environmental Benefits:
Carbon sequestered annually by nearly 4,000 acres of pine or fir forests, annual greenhouse gas emissions from more than 3,500 passenger vehicles, or carbon dioxide emissions from 43,000 barrels of oil consumed. Annual energy savings equate to powering nearly 1,900 homes and heating more than 1,000 homes. Estimated emissions reductions of 0.0051 million metric tons of carbon equivalents.
LMOP Partners Involved:
Caterpillar, Inc.

While a typical landfill gas (LFG) energy project provides an efficient way to reduce greenhouse gas emissions and provide energy to local businesses, the Finley Buttes Regional Landfill takes energy efficiency to the next level. The combined heat and power (cogeneration) facility takes the excess heat normally lost in the energy generation process and uses it nearby for industrial heating. This process greatly increases the energy efficiency of conventional energy production from around 45 percent up to 80 percent.

LFG is captured at the landfill and transferred via pipeline to the Finley Buttes facility, known as Finley BioEnergy, where the gas is used to generate electricity. This electricity is purchased by PacifiCorp, a large power company serving several states in the West.

While electricity is simple to transport long distances, the heat by-products are more efficiently used close to the facility, due to the high rate of energy loss during its transport. Conveniently, a nearby company, Cascade Specialties, Inc., uses the heat to dehydrate onions and garlic, offsetting some natural gas usage.
