IESO Tweaks Modeling for Outage Management
IESO begins its resource adequacy evaluation by derating its installed resources and imports (left column) based on factors such as effective forced outage rates. The resulting “available” resource stack (middle column) is measured against the projected demand forecast and required reserves. If there is excess capacity (right column), the ISO has a positive Reserve Above Requirement (RAR). | IESO

IESO is changing how it projects renewable generation output and its accounting for imports and planned loads in the forecasts it uses to manage generator and transmission outages.
