How will ERCOT respond to anticipated weather events and holidays for establishing load distribution for the State Estimator?
The default distribution is the State Estimator hourly distribution for the seven days before the Operating Day. If ERCOT decides, in its sole discretion, to change this distribution for reasons such as anticipated weather events or holidays, ERCOT personnel shall select a State Estimator distribution from a proxy day reasonably reflecting the anticipated distribution in the Operating Day. The business process for selecting the proxy day that matches a historical day with the anticipated temperature profile for weather events, and uses a weekend proxy for holiday events (Protocol Reference 4.5.1 (5)).
