Deschutes Brewery and Holladay Park Plaza Save with the Energy Trust of Oregon

Since 2002, Energy Trust of Oregon have saved and generated 728 average megawatts of electricity and 52 million annual therms of natural gas. This is enough energy to power Multnomah and Washington counties while heating Deschutes County homes. ETO has saved enough energy equal to the output of a power plant and reduced reliance on fossil fuels. In total, they have invested $1.5 billion to save customers more than $6.9 billion on their energy bills over time. They have also added $5.7 billion to the local economy, including $1.7 billion in wages, $312 million in small business income and employment equal to 4,700 full-time jobs lasting a decade. Carbon emissions have been cut by nearly 20 million tons, equal to removing 3.5 million cars from the roads for a year. Efficiency remains the least expensive energy resource Oregonians can buy. This affordable energy supply helps utilities avoid investment in new and more expensive energy resources. The following articles are just two examples of such success stories.

Deschutes Enjoys a Long Draft of Energy-Cost Savings

Deschutes Brewery has a long history of engaging in energy-efficiency projects, and is reaping the rewards: $34,500 in estimated annual energy cost savings.

In 2004 when Deschutes Brewery went through a major expansion of its Bend brewing facility, the brewery made sure its new 40,000-square-foot warehouse was a model of efficiency. Built to exceed Oregon energy code, the well-insulated concrete warehouse maintains a 64° F temperature year-round by taking advantage of free cooling available from Central Oregon’s cool night air. Both the warehouse and the packaging line have low-wattage T5 high-output fluorescent lighting and occupancy sensors.

Deschutes’ brewing operation is fueled by energy-efficient boilers with stack economizers that reclaim heat from the ue gas and loop it back into the feed water. In addition, a vapor condensing heat exchanger on the brew kettle helps preheat the next batch of brewing water. Deschutes also replaced four inefficient glycol pumps on its chilled water system with two new efficient glycol pumps with variable frequency drives. “These new pumps help us to produce more beer with less energy,” said Ron Shoemaker, maintenance manager, Deschutes. “They boost product quality, and they cool our fermenters faster, so we get more tasty beer out the door.”

Energy-Saving Improvements

  • Passive cooling
  • Energy-efficient lighting
  • High-efficiency glycol pumps with VFD
  • Compressed air leak detection and repair
  • High-efficiency foodservice equipment

Estimated Savings

  • 473,000 annual kilowatt hours
  • 6,300 annual therms
  • 237 annual tons of carbon dioxide
