SMUD is constructing a new substation in Sacramento at the north end of 20th Street, north of C Street and the Union Pacific Railroad tracks. The new Station E Substation will replace the North City Substation. Constructed in the 1950s, the North City Substation is nearing the end of its planned operational use.
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 E Substation will directly serve the midtown and downtown areas, improving energy reliability and capacity.
The scope of work for Final Construction includes:
- Grading and surfacing
- Construction of concrete foundations and control building
- Underground conduit and grounding
- Steel structures and equipment (transformers, circuit breakers, switches)
- Electrical buss and wiring
- Testing and commissioning
- Cutover of overhead and underground transmission and distribution lines from the existing North City Substation
Environmental enhancements and management
Environmental leadership is one of SMUD’s core values. SMUD has invested over $16 million to haul away waste and contamination that had been on the site for decades to prepare it for substation construction which begins May 2019.
The portion of the site where Substation E will be constructed is now much cleaner and safer and meets environmental and geotechnical requirements for construction.
SMUD and its construction contractor will monitor air quality during substation construction keeping an eye on dust emissions from the site. Air quality monitoring data will be made available here and updated once a week. You can also get weather conditions.
For previous reports, please email StationE@smud.org.
SMUD’s contractor is required to implement dust control measures that include the following:
- Wetting travel areas with water trucks
- Stockpile management BMPs
- Onsite speed limit
- Limited soil disturbance during high winds
- Dust monitoring
- Track out control measures
- Wet power vacuum street sweeping
July (Mid) 2019 Update
Our contractors are planning to pour the Control Building foundation on July 18. Work is planned to begin at midnight and conclude approximately at 7 AM. Due to the size of this concrete pour and the extreme heat during the day, it is important that the work be completed during off-hours (nighttime). We anticipate a total of 500 cubic yards of concrete delivered in 50 trucks during this portion of the work.
We apologize in advance for any inconvenience and appreciate your cooperation with us.
