Station J substation
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.
