PPSi and PMCo bring two G3520s to the Coffin Butte Resource Project, Corvallis

12 cooperative utilities have built their own renewable energy project by using engines that utilize methane gas given off from a local landfill near Corvallis, Oregon. The gas is produced as organic matter at the landfill breaks down. If left alone, the gas would simply dissipate into the atmosphere, increasing toxic greenhouse gas levels. Instead, the gas will be sent through two new Cat G3520 engines at the Coffin Butte Resource Project and converted into electricity, enough to power about 4,000 homes. Three older Cat 3516 engines have been in service since October 1995, providing top-notch service for the past 12 years. These older engines will join the newer 3520 engines as the generating capacity is increased. The two new 20-cylinder engines purchased this year from Peterson will more than double their current output.

Landfill gas is a top performer in the world of renewable energy. According to Kevin Watkins, Engineering Vice President for PNGC Power, the Coffin Butte team can count on 97 percent annual energy production, compared to a 30–35 percent yield from comparable wind power operations. The U.S. Environmental Protection Agency (EPA) has recognized Coffin Butte as one of the most efficient plants in the country.

The new 3520s roared to life at a grand opening celebration on October 1.

At the event, VIPs from the power co-ops and the Department of Energy, county commissioners, and a dignitary from the Northwest Power and Conservation Council spoke about the importance of the project in the ongoing quest for clean, sustainable energy sources. Vice President Watkins had some kind words for the Peterson team. “We worked very closely with Peterson to choose the best engines for the job. They’ve provided great service and we’re looking forward to working with them to keep the project up and running at full capacity.”

Steve King, Generation Resource Manager, also shared his appreciation of the Peterson team’s efforts in an email to PPSi Sales Representative Marty Hopkins in Springfield. “It’s been great working with you and I appreciate your willingness to go the extra mile to provide the best service possible!”

Machinery President Jeff Goggin, Commercial Engine Sales Manager Vern Booth (PPSi), EPG Technician Jeff Duff, as well as Marty Hopkins, all were on hand for the grand opening. Ever diligent, each one was seen throughout the afternoon carefully checking readouts on the engines and switchgear. When asked, they all had the same answer, “All systems go.”

Congratulations to all the Peterson people who helped on this important, high-profile project.
