Brandon generation must be re-dispatched from HVDC generation at Dorsey After 60 MW re-dispatch is complete, should RTCA continues to indicate a post contingent overload condition on Y51L due to the contingent loss of D14S, Continue to re-dispatch generation from Brandon gas in 10 MW increments until post contingent overload on Y51L has been mitigated. The mitigation must be completed within 30 minutes.
