    About the AESO

    Keeping the grid safe and reliable

    The Alberta Electric System Operator (AESO) manages and operates the provincial power grid.

    We're a not-for-profit organization with no financial investment in the industry. On behalf of Albertans, we work with industry partners and the government to make sure reliable power is there when you need it. Whatever changes happen in the world, you can rely on us to manage the electricity markets and meet your energy needs. From integrating renewable energy into your life to developing the grid, the future for electricity in Alberta looks bright.

    What do we do?

    • Manage and plan the power grid 24 hours a day

      When you need power, you expect it. We work with industry partners to keep electricity flowing throughout the province. Our System Controllers balance supply and demand 24/7, making sure four million Albertans have power when they need it.

    • Manage and operate the energy markets

      In Alberta, companies own generation, transmission and distribution facilities. We dispatch the power sold by generators, using the lowest-priced electricity first and then the next lowest until the need for power has been satisfied. This is the basis of Alberta's competitive electricity market, and it's worked well for over 20 years. We also enforce transmission tariffs and regulations, keeping the market fair and open for everyone.

    • Plan the future of the system and its infrastructure

      As Alberta grows, so does its need for electricity. We plan ahead and expand the grid, ensuring the right transmission lines are built as efficiently as possible. As the province moves away from coal-fired power plants, we're enabling investment in renewable energy. In everything we do, our eye is always on the future.
