Siemens Working with Edison to Ensure High Quality, Dependable Power to Southern California.

RALEIGH, N.C. -- Project will strengthen transmission path between Arizona and California

E[acute accent]Siemens Power Transmission and Distribution announced it has been awarded a major contract from Southern California Edison (SCE) for a turnkey static volt amperage reactive (VAR) compensation system (SVC). E[acute accent]As part of the contract, Siemens will design, furnish, and install a static VAR compensator at SCE's Devers 500 kV substation located near Palm Springs, Calif. The SVC has a nominal rating of -110 MVARS to + 605 MVARS. This SVC will be one of the largest units installed in the United States. E[acute accent]"The SVC will strengthen the Devers-Palo Verde transmission path from Arizona to California, benefiting electrical power users on the western United States' 500 kV power grid," said Jim Kelly, SCE's Vice President of Engineering. "The SVC adds additional voltage support in the Palm Springs area, which will help SCE increase its import transmission capability during high demand periods." E[acute accent]Siemens will work in concert with Beta Engineering of Pineville, La. Beta will provide all construction-related items on the project and will manage the construction process. The expected in-service date is late summer 2006. E[acute accent]"Siemens is pleased to provide a key component for Southern Californian Edison," said Gerd Ottehenning, Vice President of Siemens Power Transmission and Distribution, High Voltage Systems Division. E[acute accent]SVCs are also used to dampen power swings, improve transient stability and reduce system losses by optimized reactive power control. SVCs are one type of flexible alternating current transmission systems (FACTS). FACTS devices are used for the dynamic control of voltage, impedance and phase angle of high voltage AC lines. They also provide strategic benefits for improved transmission system management through: better utilization of existing transmission assets; increased transmission system reliability and availability; increased dynamic and transient grid stability; and enabling environmental benefits. FACTS devices are also used to provide increased quality of supply for sensitive industries (e.g. computer chip manufacture).
