AltaLink has built the Western Alberta Transmission Line (WATL) to ensure that Albertans have reliable electricity now, and a future that uses clean renewable energy sources
Electrical power must increasingly come from sustainable sources. AltaLink is harnessing innovation to enable a future of reliable and affordable renewable energy for Albertans. That's Ingenuity for life.
Albertans want to ensure they have a reliable and flexible electricity system that's also designed for a future based on renewable sources. Provincial utility AltaLink is making that happen, after completing the Western Alberta Transmission Line (WATL) - part of a powerful backbone that enables the province to take full advantage of its abundant wind power.
A key attribute of WATL is the bidirectional flow of power. WATL can transmit energy north to south and also capture wind power in the south and send it northbound for distribution province-wide. Converter stations with high voltage direct current (HVDC) technology are located near Calgary and Edmonton. Direct current (DC) is more stable and up to 50 per cent more efficient than the standard alternating current (AC) transmission.
WATL has the potential to deliver an environmental benefit equivalent to taking tens of thousands of cars off Alberta roads.
Innovative Siemens technology helps make WATL possible. AltaLink and its customers can count on a greener energy future.
Siemens was a trusted partner. They understood how important this project was to AltaLink. They were so professional and committed to our success.
Ingenuity for life with Siemens and AltaLink
Innovative Siemens technology is helping AltaLink deliver electricity from wind power. Albertans can rely on AltaLink to provide a greener energy future.
The "gee whiz wow" factor: Two new converter stations are critical to WATL. The converter station's showpiece is the valve hall, which showcases Siemens innovation, superior engineering and technology.
Sophisticated technology at AltaLink's substations: Large sub-stations near Edmonton and Calgary convert AC and DC currents for transmission. High-voltage direct current (HVDC) is need to enable bidirectional transmission.
