As part of a broader process of implementing the reliability standard, AEMO runs the Medium Term Projected Assessment of System Adequacy (MTPASA) process weekly to forecast expected unserved energy levels over a two year period. If the expected annual unserved energy exceeds the maximum level specified by the Reliability Standard, a Low Reserve Condition is identified.
