The SC uses a deterministic
approach based on estimates of the magnitude of likely outages
(aggregated results) and the expected system load. The TA
and the SC will present, each one on its own WEB site, the
results of their assessments for the entire Alberta electric
power system. The results will be presented in graph format
for time intervals that could vary from the next seven days
(one-week) to the next 364 days (one-year). The graphs will
be updated daily on workdays. No updates will be made on weekends
and official holidays. The graphs are designed to make it
easy for the public to identify the coming time periods when
the supply surplus, if any, is going to be "tight".
The "deterministic approach" used by the SC consist in calculating,
on a daily basis and for different possible scenarios, the
difference between the total amount of MW available for supply
and the daily peak demand. The daily ranges (min-max) of these
possible differences (balance values) are presented in the
graphs.
