Duke Energy reduces emissions, fuel use with coal-plant locomotive
Duke Energy is buying four high-efficiency, diesel-electric locomotives that are expected to cut by 75 percent the engine emissions tied to hauling coal at some of its large power plants.
Dukes started using the first engine at the Marshall Steam Station north of Charlotte in June. It has bought two additional locomotives- one for the Asheville Plant in Skyland and on for the Mayo Plant in Roxboro. A fourth locomotive will be purchased by the end of the year, Duke spokeswoman Lisa Parris says.
The LEAF engine built by RailServe uses a high-efficiency alternating-current generator that requires less horsepower from the diesel engine to provide the electricity that runs the trains ferrying coal from the plants' storage piles to the boilers.
Duke equipment specialist and CCFC chairman Dave Navey demonstrates the locomotive and describes how it works in the video below.
