Western Area Power Administration (WAPA), Rocky Mountain Region (RMR) proposes to approve an interconnection Delivery Point (DP) request from Tri-State Generation and Transmission Association, Inc.'s (Tri-State) on WAPA's existing Airport-Whitney 115-kV Transmission Line in Weld County, Colorado. The request allows transfer of existing load from WAPA's existing Windsor and Airport Substations to Tri-State’s new Iron Mountain Substation to mitigate loading of the existing substations and provide improved reliability.
