        • Cancellation of a Non-Credible Contingency Event: Farrell-John Butters line and Farrell-Rosebery-Newton-Queenstown line in TAS1 due to Lightning.

          AEMO ELECTRICITY MARKET NOTICE

          Cancellation of reclassification of a Non-Credible Contingency Event as a Credible Contingency Event due to Lightning. AEMO considers the simultaneous trip of the following circuits is no longer reasonably possible. There is no longer any lightning activity in the vicinity of the following lines. Accordingly its classification has reverted to a non-credible contingency event.

          Region: TAS1

          Lines: Farrell-John Butters and Farrell-Rosebery-Newton-Queenstown

        • 63893 15 Aug 2018 8:27 CONSTRAINTS
        • New Victorian system normal voltage stability limit

          AEMO ELECTRICITY MARKET NOTICE

          A new Victorian system normal constraint equation has been implemented on 15 August 2018 at 0825 hrs. This constraint equation is to manage voltage stability for loss of all APD potlines for transfers from Victoria to NSW. This will most likely limit Victoria to NSW flows under light load conditions.

          The new constraint equation is :
          V^^N_NIL_1
