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:
- 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).
- Reduced power price volatility due to regional and potentially inter-regional price arbitrage.
- Generate increased profitability for wind and solar energy generators by time-shifting the delivery of some of the energy output.
- Reduced GHG emissions resulting from increased renewable energy generation.
The project is anticipated to enter into operation in 2019.
