Automatic Transfer Switch Installation Project Begins on Union Street Near City Hall

On Friday, September 6, Pasadena Water and Power (PWP) will start a construction project on the south side of City Hall to install an Automatic Transfer Switch (ATS). This equipment will enhance the building’s power reliability. In the event of a power outage on the power distribution circuit feeding City Hall, the ATS will automatically switch to another circuit to keep power flowing to the building.

During construction, crews will trench on Union St. between Euclid Ave. and Garfield Ave., and install the ATS on a concrete pad adjacent to City Hall. Construction will last four weeks and will affect traffic flow on Union St.

The first 10 days will involve work in the street, where temporary traffic control measures will occur on Union St. between Los Robles Ave. and Marengo Ave. An individual lane closure will have the maximum impact at any time during work in the street. During the final three weeks of the project, crews will close a small section of the sidewalk. During this time, pedestrians will be directed to cross on the south side of Union St. between Euclid Ave. and Garfield Ave.

“Pasadena Water and Power is improving local infrastructure every day,” said David Reyes, PWP Interim General Manager. “Important projects like the automatic transfer switch at City Hall help build system reliability and ensure we’re prepared to continue serving the public during emergencies.”
