Alberta-Saskatchewan Intertie Storage (ASISt) Project

The Alberta Saskatchewan Intertie Storage (ASISt) project will combine compressed air energy storage (CAES) technology with a new, 150 MW interconnection between Saskatchewan and Alberta. This will be the first facility in the world to combine a CAES facility with an interconnection between grids. The facility will be located near Lloydminster, Alberta and it is anticipated that the CAES facility will have 135MW-160MW of generation capacity.

The ASISt project will deliver the following benefits:

  1. Increased reliability of the grid systems due to the matching of supply with demand and the delivery of ancillary services (i.e. fast ramping service).
  2. Reduced power price volatility due to regional and potentially inter-regional price arbitrage.
  3. Generate increased profitability for wind and solar energy generators by time-shifting the delivery of some of the energy output.
  4. Reduced GHG emissions resulting from increased renewable energy generation.

The project is anticipated to enter into operation in 2019.
