Station J substation

The Station J substation would improve the reliability and capacity of downtown Sacramento.

SMUD is proposing to develop a new substation in Sacramento on a 10.3-acre site at 1220 North B Street in a developed area of downtown Sacramento. The project would consist of demolition of existing on-site structures and construction on new infrastructure to support up to five 40 MVA (megavolt amperes) 115/21kV transformers for a total of up to 200 MVA.

Substations are critical links in the electrical distribution system. Electricity travels through SMUD’s transmission system to substations where it can be converted to a lower voltage before safely being delivered to homes and businesses. The Station J Substation would directly serve the midtown and downtown areas, improving energy reliability and capacity.

Anticipated activities

The proposed scope of work for Final Construction includes:

  • Excavation, grading and surfacing
  • Construction of concrete foundations

 Installation of:

  • Underground conduit and grounding
  • Steel structures and equipment (transformers, metal clad switchgear, circuit breakers/switchers, switches)
  • Electrical buss and wiring
  • Testing and commissioning
