Black & Veatch and InfraSource develop largest underground high voltage system in the nation for PG&E


Kansas City, Mo., Oct. 21, 2002 — Black & Veatch announced that significant steps have been taken to advance the installation of the largest underground extruded dielectric high voltage transmission system in the U.S.

The project, which was awarded to Black & Veatch on June 11, 2002, by Mueller Pipeliners, an InfraSource company, includes the design and construction permitting of 11.4 miles of 230 kV underground transmission line that will interconnect two new substations in the Tri-Valley of Northern California.

The new substations are expected to meet increased power demand for the areas of North Livermore, East Dublin and Pleasanton. To date, Black & Veatch has performed preliminary design associated with PG&E’s environmental permitting of the transmission route, as well as development of technical specifications. This work was performed under a previous contract with PG&E.

The project consists of two new power substations in North Livermore and East Dublin, and the expansion of a Pleasanton substation. The utility will also install 14 miles of high-voltage transmission lines, with 11.2 miles of those lines underground — the most ever buried in a single project, according to PG&E spokesman Jason Alderman.

According to PG&E, the Tri-Valley uses 98.6 percent of the systems’ available electrical capacity. When the substations are complete they will decrease the power flow through existing lower voltage transmission lines and, therefore, increase the amount of energy that can be transmitted. As a result, the improvements will subsequently expand the energy capacity and reliability for the Tri-Valley area, ensure power to emergency services and bolster future business development and retention.

“Our (PG&E/InfraSource/Black & Veatch) team’s primary objective is to ensure power delivery without interruptions for PG&E’s customers,” said Black & Veatch Project Manager John Rector. “The decision to build this underground voltage system was timely since the area was on the verge of localized rolling blackouts. We expect for the project to be operational for next summer’s peak.”

The initial phase of the project is scheduled for completion in June 2003.
