Electric Power Systems’ SCADA project experience includes:
SCADA System Engineering, Procurement and Construction
City of Soldotna, Soldotna, Alaska
The City of Soldotna desired to upgrade their existing control system, which was limited due to age, technology employed, and the number of sites at which it was deployed. EPS teamed with the prime contractor AirTek of Soldotna to provide the City a new SCADA system. EPS performed all of the design engineering for the electrical installation and the UL 508A control panels. In addition, EPS provided the materials for the control system, including a Wonderware HMI (human-machine interface), four GE 90-30 PLC’s for the well sites and reservoir, and the 920 MHz radio system to allow the remote sites to communicate with the HMI at the treatment plant. EPS programmed the PLC’s and HMI, assisted AirTek with construction-related engineering, and provided final startup, commissioning, and training for the Owner. EPS staff worked with the electrical contractor as a subcontractor, while keeping the goals of the owner in mind. The project was completed on time and budget, with only minor changes required from the original design. EPS has maintained a working relationship with both the owner and the contractor in the ensuing years. In fact, EPS continues to work for the City upgrading and adding facilities to their SCADA system. Since the completion of this project, EPS has added two additional wells and one reservoir, and has discussed the costs and requirements for adding the waste water facilities into the system.
