A pioneering power control project at the New York Power Authority’s (NYPA’s) Frederick R. Clark Energy Center promises to increase the amount of electricity that can be moved reliably over existing transmission lines.
The Convertible Static Compensator (CSC) reportedly will allow power flows through the Utica-Albany transmission corridor to increase by approximately 60 MW. Major transmission lines from all areas of the state converge in central New York, causing the state’s most serious transmission bottleneck along the Utica-Albany corridor.
The improved power flows are a result of Phase One of the CSC project. With completion of Phase Two next year, the project not only will move more power over existing lines, but will have the capability to route power away from heavily loaded lines to underutilized lines. When fully operational, the CSC is expected to increase power flows by some 240 MW over all transmission corridors in the system.
Work on the CSC began in May 1999. After nearly two years of construction and months of testing, NYPA’s Energy Control Center at Marcy notified NYISO that Phase One was ready this past April 2.
The Power Authority’s CSC is the latest generation of FACTS (Flexible Alternating Current Transmission Systems) technology. Combining solid-state power electronics, microprocessors, computers, advanced automation, communications and power system analysis software, FACTS provides control of power delivery, minimizes line disturbances and helps to reduce power interruptions. The CSC development and installation is a collaborative $48 million effort by the NYPA, EPRI, Siemens Transmission and Distribution, and more than 30 electric utilities worldwide.
