SMUD is proposing to replace the existing substation equipment which includes the transformer, switchgear, and 69kV switch pole. In order to properly bring the substation up to present standards the civil engineering work will also be redone. This civil work includes adding an oil containment pit, with oil minder sump control and a battery slab. Additionally, some of the underground conduit will need to be replaced which house the 12kV feeder getaways and capacitor bank cables. New conduit will be added for offsite power. The substation gate will also be replaced and improvements will be made to the driveway. Lastly, the new equipment will require additional grounding, placed 18 inches from the foundations. The site of the substation is listed as general commercial in the city of Citrus Height's GP. Commercial properties including businesses surround the substation. The upgraded substation equipment will not create a need to increase the existing footprint.
The ground conditions in the substation area are made up of crushed gravel. Construction is anticipated to start in Oct 2018 or soon thereafter and last for approx 9 months.
