What this dataset contains
Generation from major hydro, small hydro, coal, oil, wind, solar and biomass, plus battery energy storage system power. The available report covers 11 September 2026, with 95 readings from 00:15 to 23:45.
How it is used here
The chart shows stored battery-power readings. The table also supports queries for every reported generation source and timestamp, including the 18:45 BESS value of 9.996 MW on 11 September 2026.
What it cannot tell you
This is a stored snapshot, not a live feed or complete historical archive. Source timestamps have no explicit timezone offset; missing readings are not filled. MW is power, not MWh of stored or delivered energy. Aggregate BESS telemetry does not identify an individual installation.
