The APO 26-year long term demand forecast is produced at an hourly and zonal resolution and at the net-level, generator-level demand, under a normal weather scenario and is based primarily on a sector/sub-sector/zonal/end-use/efficiency level/fuel-type/annual and an 8,760 hourly load profile model, with additional adjustments for special sectors such as agriculture, transportation, other sources of需求,保护和需求管理(CDM)计划和法规(包括住宅需求响应计划),工业保护计划和嵌入式一代。预测已通过实际的历史需求数据进行校准,并与IESO的区域电力计划计划活动的发现保持一致。本文涵盖了需求预测的发展方法。
