When Invenergy planned a 69 turbine wind project with a generation capacity of more than 103-megawatts on nearly 5,000 acres in Kittitas County in central Washington, it needed a new switching station to make that connection. Using an engineer-procure-construct (EPC) contract, we helped Invenergy move the new switching station project forward on a time-sensitive schedule so it would be ready when the first set of turbines began to spin in the winds along a ridge line just north of Interstate 90.

We completed the Poison Spring switching station ahead of schedule, allowing Invenergy to keep what they have named the Vantage Wind Farm on track. The project includes a 230-kV 3-breaker ring bus (with space for a fourth breaker) adjacent to an existing 230-kV line. Project features included clearing, grading, fencing, bus grounding, and erection of three dead end towers, three sets of potential transformers, and a control house with security and SCADA. The Vantage Wind Farm will provide power to Puget Sound Energy.
