Municipal Electric System

Location: Ames, Iowa

Client: City of Ames

Burns & McDonnell performed the initial feasibility and planning study for this system for the City of Ames, Iowa. Later, we provided design services, including system specifications, bid evaluation and contract administration. Our transmission and distribution substation section also provided substation integration design including I/O point wiring, transducers and interposing relays and the installation contract.

This SCADA/EMS system consists of a dual Landis & Gyr 6800 and fifteen Telegyr 5310 and 5520 remote terminal units. The feature of this system includes sequence-of-events (SOE) reporting and NOAA satellite time synchronization. The EMS includes automatic generation control (AGC) of one 65-megawatt coal fired unit, one 30-megawatt refuse-derived fuel (RDF) fired unit and one 16-megawatt combustion turbine with economic dispatch, interchange transaction scheduler, cost of interchange and unit commitment.
