The Minneapolis Energy Center (MEC) supplies steam and chilled water to more than 100 buildings in the downtown area. MEC’s system operates five interconnected plants, two stand-alone plants and two County. MEC recently completed a two and half year project to remove and replace its existing Bailey Distributed Control Systems (DCS) with Emerson Delta-V DCS. All components of the existing system were removed - including termination units, power supplies, I/O modules, processors, Operator Work Stations etc. Due to the plant’s continuous operation schedule, the control systems required replacement in five phases.
