The Engineer works collaboratively with Design, Construction, Operating and Maintenance workgroups to identify, justify and initiate projects for optimum electric subtransmission system development (bulk supply substation, 34 kV and 69 kV lines, distribution substation), renewable distributed energy resource (DER) integration, and provides various technical support. Use computer modeling techniques and engineering expertise to assess electric subtransmission system adequacy and to identify the optimum size, configuration, DER hosting capacity, and timing of changes to facilities.
