Load Shed Services for imports
Load Shed Services for imports (LSSi) is a transmission system reliability product developed as part of our efforts to fulfill our intertie restoration obligation as mandated by legislation. LSSi is provided by load customers that agree to be quickly taken offline following the sudden loss of imports coming across the interties.
This load shedding allows for arrest and recovery from frequency decay, and preserves system stability. LSSi is used to manage frequency risk so import intertie capability can be increased, allowing additional scheduled imports to access the Alberta market without compromising system reliability.
The AESO currently has contracts in place with various loads in Alberta to provide this service.
