SMUD: Construction of new Station E substation expected to begin this year

The Sacramento Municipal Utility District (SMUD) on Feb. 23 said that construction of a new substation – the Station E substation – is expected to begin this year and to be completed in 2020.

The approximately $76m project will enhance reliability for customers in the midtown neighborhoods and provide vital backup support to downtown Sacramento, as well as the entire SMUD grid, SMUD said.

The substation transmission voltage when built will be 115 kV – converted to 21 kV for distribution, a SMUD spokesperson told TransmissionHub on March 1.

The new substation is replacing the existing North City substation, which is more than 60 years old and has reached end of life, SMUD said, noting that the Station E construction project follows the city of Sacramento’s plan for growth.

According to the project’s website, the new substation will be built at the north end of 20th Street, north of C Street and the Union Pacific Railroad tracks.

In its statement, SMUD noted that in addition to the construction of the new substation, it is also cleaning up land at the site that SMUD purchased in 2013 to build the substation.

As noted on the website, SMUD plans to invest up to $13m to haul away burn waste that has been on the site for decades and to prepare the site for substation construction currently planned for the end of the year. An impermeable cap will be installed on a portion of the site that will not be used to build the substation, the website noted, adding that the cap will seal the ground area to prevent waste from being uncovered and posing a risk to public health or the environment.

Environmental clean-up efforts are expected to begin in the spring and continue throughout the summer, the website said, adding that anticipated activities include excavating and removing about 64,000 tons of waste material.
