Transmission information button

Alberta's electricity transmission system is the electrical equivalent of our highway system. Transmission lines move electricity from where it is generated to where it is consumed. Sustainable, long-term growth means making sure infrastructure is built, and that means power plants, wind farms and transmission lines are in place to meet the electricity needs of Albertans. In the development of transmission lines Alberta’s tradition of good planning and respect for landowners remains in place.

Alberta's electricity system is owned and operated by a mix of investor-owned and municipally owned companies, not by the Alberta government. To ensure Albertans of a long-term, reliable supply of competitively priced electricity, Alberta Energy develops, supports and monitors the framework for bringing new generation on-line, competitive electricity markets, and efficient delivery systems.

Investor confidence in Alberta's competitive electricity market has resulted in over 9,000 megawatts (MW) of new installed electricity generating capacity since 1998. In addition, industry has expressed interest in investing in another 10,272 MW of new power development in coming years, which will ensure we continue to meet our province's growing demands.  To put this growth in perspective, one MW of generating capacity could generate enough electricity to power over 1,000 typical Alberta households.

Thermal sources account for the majority of Alberta's installed generating capacity: coal-fired plants make up about 38 per cent of the province's total installed generating capacity, and natural gas accounts for about 44 per cent, including efficient cogeneration at industrial operations that produce energy as a by-product of their normal activities. The remainder is hydro, wind and biomass (energy produced from organic sources such as wood waste, garbage or animal matter).

The ability to deliver electricity throughout Alberta must also be increased in order to keep pace with demand.
