Overview

The freshest system-wide reading.

Query contract

Preserve one canonical row per (event_time) before aggregating.

Analysis rules

Read the latest poll at or before the time asked about.

Interpretation

event_time is when the collector polled AESO's report (every five minutes), not a time AESO published; the report carries no source timestamp of its own.
Use only the total_* columns. The per-fuel columns carry one gas sub-type per poll and undercount gas several-fold: take generation by fuel from aeso.unit_status.

Dataset	Description
AESO Alberta Internal Load (hourly)AESO · hourly, after the hour	Alberta internal load (AIL) for each completed hour, as AESO publishes it beside the pool price.
AESO Load ForecastAESO · retrieved every 15 minutes; 14 days ahead	AESO's hourly Alberta internal load forecast, every retrieval kept, reaching about two weeks ahead.
7-Day Load ForecastPJM · hourly (7-day horizon)	PJM's seven-day-ahead hourly load forecast by forecast area, refreshed through the day. Rows are keyed by target time (event_time) with the issue time in evaluated_at_utc; take the latest vintage per target hour via an argMax over evaluated_at_utc. Forecast areas match the very-short-term feed (utility names, RTO_COMBINED for the system total). This is the table for tomorrow's peak and the week-ahead demand outlook. Source: PJM Market Data.
Actual Demand by RegionMISO · hourly	Observed hourly MISO demand in MW for the Central, North, and South sub-regions. Region labels are normalized to uppercase; this is regional operational load, not a local-resource-zone series.
