Ulteig was hired by Pattern Energy to design a system to collect energy from the 377-turbine Western Spirit Wind Projects through four collection substations. Electricity would then be transmitted through 67 miles of 345 kV AC transmission lines (the GenTie Transmission) to the 155-mile Western Spirit Transmission line. The collection substations were designed with power metering equipment that meets the California ISO (CAISO) metering requirements.
