Actual Flow and RAS Status

The instantaneous actual flow (MW) on 5L61 and the 5L61 tripping Remedial Action Scheme (5L61 RAS) status (ON/OFF), sampled every five minutes, are displayed. The 5L61RAS allows the controlled separation of North Coast area including Alcan system from BC Hydro for loss of 5L51 and 5L52 during BC Hydro import period. This RAS allows the tripping of 5L61 for the simultaneous loss of 5L51 and 5L52, or loss of 5L51 (or 5L52) with 5L52 (or 5L51) out of service during high US to BC and Alcan to BC Hydro transfers.
