Time flies. It's already been five years since Dallman 4, CWLP's newest power station began producing electricity. On May 11, 2009, powered by natural gas, the 200-megawatt (MW) Dallman 4 produced 13 MW of electricity as the unit was synchronized to the electric grid for the first time. About three weeks later, on June 1, the first coal burn took place in the D4 boiler. By August 1, still in its testing phase and operating at 230 MW (30 MW above the unit's nameplate capacity), D4 had produced 119,360 megawatt-hours (MWH) of electricity. That same month, Dallman 4 was named POWER magazine's 2009 Power Plant of the Year. In mid-November, with testing completed, CWLP assumed control of the power plant from the general contractor—KBV Springfield Power Partners. To learn more about the events leading up to and through construction of Dallman 4, as well as the histories of other aspects of City Water, Light & Power (including the story of how and why CWLP was created, the histories of the Electric and Water Divisions, and the building of Lake Springfield), check out our online historical pamphlets and videos (or order your free pamphlet copies while supplies last).
