Response to DPU Data Request 19.1 PacifiCorp's Transmission Project Management Office (PMO)has demonstrated expertise in integrating complex transmission projects with the transmission system. Similarly,PacifiCorp's Generation PMO has demonstrated expertise in integrating major generation projects with the transmission system.These entities will coordinate on project execution plans,commissioning,and integration of the Energy Vision 2020 Combined Projects to link the transmission project implementation with implementation of the new generationprojects.The Transmission Projects construction schedules have been developed in such a way that the 230 kV transmission network additions will precede the completion of the 500 kV transmission system additions. The earlier completion of the 230 kV system will provide station service and synchronizing power to each wind farm,allowing each wind farm to proceed with testing and commissioning of each wind turbine,either one at a time or on a group basis.The 230 kV temporary power resource is anticipated to be available approximately June 1,2020,to begin wind turbine generator commissioning.During this process,test energy will be injected from a wind farm into the 230 kV transmission system.This process will continue until all turbines in a given farm have been tested and evaluated.If at the completion of the wind turbine testing phase stop-gap measures have been identified as necessary due to critical 500 kV transmission system improvements not being completed,a "round robin"generationrotation scheme would be implemented that would bring each wind turbine or group of turbines on-line on a regular basis,then that set of turbines will be taken off-line and another set of wind turbines will be brought on-line,etc.Utilization of wind plant control systems would facilitate this generationrotation scheme.
