Northern Power Systems has completed construction of 22 turnkey power systems including and eight TelePower™ diesel-photovoltaic (PV) hybrid systems for the Corridor Pipeline Ltd. in Canada.Waitsfield, Vermont – August 15, 2002 [SolarAccess.com] The systems will power main line block valve actuation at strategic points along a 493-kilometer dual pipeline, which runs from the Muskeg River Mine, north of Fort McMurray, to Scotford, north of Edmonton, Alberta. Northern has built 14 GridTie™ grid-connected systems and the eight TelePower™ diesel-PV hybrid power systems. The 22 systems were built at a production facility located in Morrinville, Alberta, just north of Edmonton. After successful completion of a Factory Acceptance Test, the systems were transported to their final locations along the pipeline. The GridTie systems are connected to existing power lines, providing an uninterrupted power supply in case of a power outage. The TelePower systems have been installed at remote sites where no grid power is available. These systems use PV modules as the primary power source, with diesel gensets providing back-up power during times of low solar energy. In addition, lead-acid batteries are used as the energy storage medium. A Northern SC-1000™ controller is used to control system operations.
