STV 100th Anniversary
  Switchyard Replacement (Lock Haven , PA)




STV was contracted to perform a feasibility study for a preliminary assessment of alternatives for the replacement of the Lock Haven Switchyard. STV was responsible for all civil/land development, environmental, and project management services. The company subcontracted the services of a transmission line engineering firm for the switchyard/substation equipment and layout component of the project. The new switchyard will ultimately be designed to 138 kV standards (operated at 69 kV) and be the client’s standard breaker-and-a-half open air configuration, capable of terminating eight 69 kV transmission lines.
