Title

Dillard-Orange Neighborhood Electric Distribution Expansion Project

Description

SMUD proposes to construct and operate an upgraded and expanded electrical substation. The proposed project consists of increasing the footprint of the substation on existing SMUD property by approximately 0.04 acre, adding a 6.25-MVA transformer to the existing substation, which currently contains a 6.25-MVA transformer, thus increasing the capacity of the substation from 6.25 to 12.5 MVA. Additional improvements include paving the entrance of the substation, excavating and pouring a transformer pad, and adding approximately 300 feet of 69-kV subtransmission line to an existing 12-kV distribution line located on Orange Road, resulting in a 69-kV subtransmission line with 12-kV underbuild. The project would also result in the installation of approximately 365 feet of underground 12-kV distribution line. The 69-kV and 12-kV overhead and underground work would require the installation of three utility poles (two on the east side of Dillard Road and one on the south side of Orange Road), and the installation of a buried pull box on the west side of Dillard Road. In addition, when future increased electrical load in the area requires increased substation capacity, the two 6.25-MVA transformers would be replaced with two 12.5-MVA transformers. Future plans also include adding additional switchgear and capacitors as well as enlarging one of the existing concrete pads. The total capacity at the ultimate build-out of the substation would be 25 MVA.
