Letting off a little steam has been a good thing for Eugene Water & Electric Board (EWEB), which is the source of power, water, and steam for residents and businesses in Eugene, Oregon. The utility is one of Oregon's largest municipal utilities with 87,000 electric customers, about 45,900 water customers, and 75 steam customers (in Eugene's downtown business district). EWEB generates 110 MW of capacity at its hydroelectric and fossil-fueled power plants; it gets the rest of its power supply from other generators, including the Bonneville Power Administration. The utility gets its water supply from the McKenzie River. Its distribution system includes 26 reservoirs, 31 pump stations, and 800 miles of water mains.
