PWC’s Electrical Engineering Department is made up of four sections:
- customer support
- support systems
- technical support
- office administration
The objective of the department is to provide engineering and other services in a timely, courteous, safe, and professional manner that is commercially competitive.
PWC currently purchases its power from Duke Energy Progress, but has the capability to generate electricity when requested by DEP. All of the purchased power is directed to one of three Points of Delivery (POD) in the Fayetteville area by way of 230,000-volt transmission lines. The higher voltage allows power to travel vast distances and more efficiently than lower voltages. At these POD’s, the voltage is transformed again to a sub-transmission voltage of 66 kV and redistributed to one of our 35 distribution substations throughout the area. The sub-transmission voltage allows the wires to be closer together and more efficient for transporting power to our distribution substations. At the distribution substations the voltage is again transformed to a lower voltage of either 25 kV or 15 kV. This is the voltage of the power lines along the streets of your neighborhood. At transformers near homes or businesses, the voltage is transformed a final time. The voltage delivered to homes and businesses is typically in the range of 122 volts but the system is designed to deliver 120 volts, plus or minus 5%, safely at any given time.
