Engineering Services for Jenks Substation Design, Apex, NC

The Town of Apex has a need to increase the capacity of its power system on western side of the service territory near US Highway 64 to accommodate planned growth in the area with a new 230kV substation. The proposed substation will consist of a 230kV-24kV, 40 MVA transformer supplying three feeders from a 2,000A bus system with provisions for another three feeders and transformer in the future. Refer to the preliminary single line. Land for the new substation has been procured and the transformer has been ordered and is scheduled for delivery in the first quarter of 2028. This project is to provide the design and engineering calculations as well as the construction documents, bid packages, and substation drawings required to construct and commission the substation. This includes all required protection, controls, and metering systems as well as design and procurement of a prefabricated control house and 48V DC battery control systems and 240/120V station power. The bus support structure shall be a lattice style support structure with the bus work arranged to match other town substation configurations. Exit feeders are to be fed by 600A reclosers (GW Vipers or Eaton Nova TS) through 576 KVA regulators (GE VR 1 or Eaton/Cooper Quickstep). The project may include the design or layout for all or portions of the exit feeders (circuit) routes. This includes load-based layout of the distribution transformers, highway crossing, and development of tie points and loop schemes for the circuit and between circuits.
