Current records
Records are calculated as the proportional contribution of wind and solar energy to
net-to-grid generation (i.e. not including behind-the-fence generation, which notably includes most cogeneration).
Hourly: 58.2% set April 3, 2024 at 13:00 Mountain Daylight Time
Daily: 50.8% set March 7, 2026.
30-Day: 34.5%, the trailing 30 days ending June 11, 2026.
Monthly: 33.6%, set in June 2026.
Annual: 25.7%, set in 2025.
The 30-day, monthly, and annual records only consider COMPLETE periods — an in-progress month or
year isn't eligible until it's actually over, since a partial period's average isn't comparable to a full one.
A note on precision: AESO doesn't publish a live net-to-grid generation total directly — this
project calculates it by summing every generating asset's own hourly metered volume and classifying each by
fuel type (see Data Sources below), which can differ slightly from AESO's own figures. The closest official
point of comparison is AESO's Annual Market Statistics report
(lags about a month), which publishes "System Generation" by fuel type — equivalent to this project's
net-to-grid figure — alongside "Total Generation," which also includes behind-the-fence generation. Treat the
percentages on this page as close approximations rather than exact official numbers; the typical gap hasn't
been precisely quantified yet.

Time shown is the start of the hour the share was measured (e.g. "13:00" covers 13:00–14:00). AESO's own reports commonly label hours the opposite way, as "Hour Ending" (HE) — their "HE 14" is this table's "13:00".

Details
No wind, solar, or storage asset changes in this period.
"Date" is when this was detected: for an added asset, its first recorded generation above 0 MW
(which can include commissioning tests and precede commercial operation); for a removal or capacity change, the day
AESO's asset list first reflected it. AESO's market updates page
has the actual details; this pipeline doesn't read it, so check there to verify.
