Keeping the Lights on in Alberta
With 212,000 square kilometers of service area, AltaLink is the largest regulated transmission company in Alberta, supplying electricity to more than 85% of the population. The transmission system is the essential link that connects homes, farms, businesses and industries to electricity generated across Alberta. Electricity generated from thermal energy, wind power and hydro is transported at high voltages over long distances through transmission lines to substations, which lower the voltage so electricity can be safely delivered to homes and businesses via distribution lines. In 2015, AltaLink energized Alberta’s first 500 kV direct current line. The 350 kilometer line will save an estimated 385,000 tons of carbon emissions each year by reducing electrical system losses.
