Klamath Cogeneration — An Award Winning Power Plant
Iberdrola Renewables, LLC worked closely with the City of Klamath Falls to develop the award-winning 536 MW Klamath Cogeneration Plant, one of the most energy-efficient advanced gas-fired power plants in the West.
When commissioned in 2001, Klamath became the cleanest fossil-fueled power plant ever constructed in the US in terms of greenhouse gas emissions. In addition, Klamath uses up to 3 million gallons per day of treated municipal wastewater provided by the City to meet 100% of its cooling needs. The highly flexible 100 MW Klamath Peaking plant was added adjacent to the Cogeneration Plant to provide Iberdrola Renewables, LLC’s customers with additional capability to meet their peak summer and winter power needs. Iberdrola Renewables, LLC manages Klamath’s fuel supply and markets the output of the plants to Western wholesale customers in California and the Northwest. Iberdrola Renewables, LLC’s affiliate, Pacific Klamath Energy Inc. (PKE), operates and maintains the plants.
Commitment to Safety
PKE has made safety a top priority at the Klamath Cogeneration and Peaking Plants. Plant staff has maintained a zero-lost-time accident rate since 2000 when the first employee was hired. In addition, PKE has earned consecutive Oregon OSHA SHARP Awards. This recognition by OSHA distinguishes the safety culture and track record at Klamath as essentially 'best in class.'
Powerful Environmental Advantages
The Klamath Cogeneration Plant set the standard for new levels of environmental performance, particularly in regard to global warming concerns. It was the model for an Oregon law that created the first CO2 standard in the nation.
The cogeneration plant creates two useful forms of energyelectricity and process steamfrom a single fuel source. Natural gas is burned using advanced, combined-cycle combustion turbine technology. Then Klamath adds a cogeneration process that creates up to 275,000 lbs/hr of steam during combustion for manufacturing use at a nearby wood-products plant, Collins Wood Products. The result is a net energy efficiency of 54 percent LHV. (Conventional coal-fired electric generationthe source of about half the nation's energy supplytypically achieves 34 percent net energy efficiency).
Cooling water for Klamath is also handled in an environmentally conscious manner. The plant is cooled with recycled municipal wastewater effluent, reducing the City’s current wastewater discharge by about 2.3 million gallons per day.
How Much is 600 Megawatts of Electricity?
Enough to supply 500,000 homes. These power plants are some of the cleanest and most fuel-efficient power plants in the world.
(1 Megawatt = 1,000 Kilowatts 1 Kilowatt = 1,000 Watts)
Typical Household Loads
Clock Radio = 10 watts
Computer = 270 watts
Hair Dryer = 1,850 watts
Microwave Oven = 1,000 watts
Box Heater = 1,800 watts
The average size generator for home or construction site use produces approximately 5,000 watts.
Where Does the Steam Go?
Cogeneration means producing two kinds of energy from one fuel source. The process steam from the cogeneration plant goes to Collins Wood Products for use in its factory. Steam from the cogen plant allowed Collins to eliminate old boilers that operate less efficiently than the cogeneration process.
The Klamath Control Room is the nerve center for these plants with 18 computer screens for monitoring and controlling plant conditions. Because of their high tech automation, the plants require just two operators for plant operationone control room operator and one outside plant operator for safe and effective plant operations. All major equipment and control systems can be remotely operated from the Control Room
Twenty three men and women are on site to manage, maintain, and operate the plant. A traditional coal-fired power plant of similar size would require more than 100 people to operate. We are proud of our safety and environmental compliance record, as well as our remarkable commitment to community service with the SMART early reading program, United Way, and other service organizations in the Klamath Basin.
