The new static VAR compressor (SVC) is expected to enhance the reliability of Allegheny’s 500kV Black Oak-Bedington transmission line, one of the most heavily-loaded lines in the PJM interconnection area, by quickly changing reactive power levels to control the line’s voltage.
David Flitman, president of Allegheny Power, said: In addition to improving reliability, the SVC will enable increased transmission capacity across the PJM region. Enabling more power to flow on existing lines is an efficient use of resources and an important step in keeping pace with the region’s increased demand for electricity, but it doesn’t negate the need to add new transmission lines to ensure continued reliability.
The project was initiated as part of PJM’s regional transmission expansion plan, and completed by the company’s Trans-Allegheny Interstate Line subsidiary. The PJM plan identifies upgrades and additions to ensure the reliability of the electric transmission system throughout its multi-state region.
