Zurich, Switzerland, October 25, 2011 — ABB won an order worth over $50 million from Hydro Quebec to upgrade vital components of a ultra-high voltage transmission system that helps transport hydroelectric power from north to south Quebec. The order was booked in the third quarter.
The two static Var compensators in the Nemiscau substation, about 620 miles north of Montreal, provide fast-acting reactive power compensation in the 735 kV electricity network. The upgrades are slated for completion by 2014.
SVCs compensate for fluctuations in the voltage and current of an electric grid, thereby allowing more power to flow through the network while maintaining network safety and stability.
They are part of ABB‘s family of flexible alternating current transmission systems technologies, which help enhance the capacity, security and flexibility of power transmission systems, and also contribute to the development of smarter grids.
By boosting power capacity in existing grids, FACTS technologies enable more power to reach consumers with minimal environmental impact, lower investment costs and shorter implementation times than the traditional alternative of building new power plants and transmission lines.
They also help address voltage and frequency stability issues and enable the transmission system to run more efficiently. ABB is engaged in FACTS, and has more than 800 such installations in operation or under construction across the world.
Hydro Quebec generates, transmits and distributes electricity, mainly using renewable energy sources, in particular hydroelectricity. It is one of the biggest electric utilities in North America.
