Black & Veatch selected to provide power distribution solutions for Northern California

Kansas City, Mo., Aug. 15, 2002 — Black & Veatch announced recently it has been selected by Pacific Gas & Electric (PG&E) Co. Inc. to provide engineering, procurement and construction of the Los Esteros Substation which is a part of the Northeast San Jose Transmission Reinforcement Project near San Jose, Calif.

The project is intended to expand PG&E’s capacity to provide electric service to the northeast San Jose area. The proposed Los Esteros Substation site is located between the cities of Fremont, Milpitas and San Jose.

Over the past 20 years, the San Jose area has experienced significant growth and is in critical need of a transmission grid upgrade to reliably serve increased area demand. The project plan, which will be executed by Black & Veatch, will link the subtransmission system in the City of San Jose to the existing 230 kV Newark-Metcalf Transmission Line and will consist of several components, including the following:

* Development of the Los Esteros Substation, which will consist of a 19-acre combined transmission substation (230/115 kV).

* Construction of two new overhead transmission lines that will be routed through the cities of Fremont, Milpitas and San Jose. This will help redistribute power to areas with the greatest demand. The transmission lines will be 78-mile long 230 kV double-circuit lines from the Newark Substation.

* Construction of an underground 230 kV transmission line that will be located in the City of Fremont. The 2.8 mile stretch of line will be built underground to limit the environmental impact to local wildlife and will use solid dielectric insulation technology to further minimize the environmental impact.

* Connection of the Los Esteros Substation to the existing area 115 kV subtransmission lines, which connect to four substations and facilities that will ultimately provide the San Jose area with more complete and reliable service.

“A growth in load has occurred throughout many parts of the United States and it has caused a demand for significant enhancements to the current transmission infrastructure,” said PG&E Project Manager Tom Marki.

“This project will not only ease the strain on the transmission grid, but will provide additional capacity support into the future. PG&E has taken a proactive approach to address this situation before it seriously impacts reliability.”

The Los Esteros Substation will occupy the northern 19 acres of a 54-acre property that is currently occupied by greenhouses and agricultural facilities. The substation will be an unattended, remote-controlled facility that will require only periodic maintenance. It will initially consist of two 230/115 kV transmission transformers, circuit breakers, bus, capacitor banks and controls.

Ultimately, a third 230/115 kV transformer will be installed. PG&E also plans to install up to four 230/21 kV transformer banks at the Los Esteros Substation. Each transformer bank would serve three 21 kV distribution circuits that connect into the 21 kV distribution system.

“These circuits will be used to connect existing loads more reliably or could be used as future distribution lines in the area of the Los Esteros Substation,” said Marki. “The distribution substation transformer banks would be added to the substation when the load is projected to exceed capacity. We anticipate that this will occur within the next 10 years.”

The Northeast San Jose Transmission Reinforcement Project is scheduled for commercial operation on June 1, 2003.
