Title

Station J Bulk Transmission Substation Project

Description

The Station J Bulk Transmission Substation Project includes construction and operation of a new substation housing electrical equipment, including power transformers, gas insulated equipment, and a control building. Station J would include up to five 40 MVA 115/21 kV transformers to serve the SMUD network. Initial installation of two 40 MVA transformers is anticipated to occur by 2030. The project would also include up to 7 miles of overhead and underground 115kV and 21kV connections into the substation from nearby existing SMUD facilities and infrastructure. The site also includes space for expansion as future needs are identified. Primary access to the project site during construction and operation would be provided by existing driveways the project site from North B Street and North 14th Street. The proposed substation site was most recently owned and operated by General Produce. All existing on-site structures would be demolished. The duration of construction is anticipated to last approximately 2 years. The construction workforce is expected to arrive at the project site between approximately 6:00 a.m. and 7:00 a.m. and leave the site between approximately 5:00 p.m. and 6:00 p.m., Monday through Friday for most of the project construction period. Materials would generally be delivered outside of the peak morning and afternoon traffic hours to the extent feasible and would be delivered to the designated receiving area.
