Renovation of a power facility in South Pasadena, California. Completed plans call for the renovation of a power facility.

The City of Pasadena is seeking proposals from qualified firms to provide engineering services for the Fair Oaks Substation Project. The project is needed to address equipment obsolescence as well as support the PWP 4-kV to 17-kV conversion program by providing 17-kV distribution capacity to replace the existing Fair Oaks 4-kV Units by converting their loads to 17-kV. This project will be completed in two phases as further described in the Scope of Work. The engineering firm is expected to perform the general tasks as described in the Scope of Work. The desired in-service date for Phase One of the project is June 2029. The engineering services requested for the project include final design, bid assistance, design build bridging documents, and engineering services during construction. question deadline date changed from 08/14/2026 to 08/26/2026 as per Addendum 2 Phase One: The project will demolish Fair Oaks Unit 3 substation and add two new unit substations, a 20 MVA 34/17-kV distribution substation and a 7.5 MVA 34/4- kV distribution substation. The new substation will be located at the Fair Oaks Substation at 1420 N Fair Oaks Avenue which has 3 units currently in service. Each new unit will comprise of a metal-clad switchgear lineup with two LTC equipped transformers, one at each end of the switchgear. Major Materials: The existing switchgear at Fair Oaks is composed of two sections connected by a bus tie breaker in the middle. Each section has one main breaker and two feeder breakers. Each unit has 4 distribution feeders in total and , since the feeders are normally half-loaded, 100% backup capability in case of failure of one transformer. Transformers: PWP will procure the four transformers required for Phase One of the project. The transformers' primary will be dual-voltage 34.5- kV and 69-kV. The 4- kV units shall be of DYN1 configuration and the 17- kV units are YNYNO with a buried delta tertiary. Phase Two: This project phase will have two locations: Fair Oaks Substation at 1420 N. Fair Oaks Avenue and Brookside Substation at 1001 N. Arroyo Blvd. Brookside Substation Scope: Installation of a new 4- kV unit substation . Demolition of Brookside Unit 2 following the commissioning of the substation . Installation of a 35kV or 69kV high side (H.S.) switchgear to replace the existing 35kV load break switches. The switchgear will enable the reconfiguration of the existing station feeds and allow for fail over and the rerouting of power between the Brookside and Fair Oaks substations. Fair Oaks Scope: Demolition of Units 1 and 2 at Fair Oaks Substation. Installation of a 35kV or 69kV high side switchgear to replace the existing 35kV high side load break switches.
