AltaLink Background


Keeping the Lights on in Alberta

With 226,000 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. Since 2015, AltaLink has delivered more than $1.4 billion in rate levelization or rate reductions for Albertans. In 2023, AltaLink fulfilled its commitment to keep its transmission rates below 2018 levels for five years.
