Hi Geoff.

Open Electricity did not 'say' anything.

But they, very quietly, changed the effect of selecting 'Consumption' or 'Generation' above the table.

So, for example, for Victoria, 7 days @ ½-hour intervals for 25 Jan 2026 10:30pm to 1 Feb 2026 10:30 pm AEST, we now get EITHER:

*** Consumption ***

Sources GWh Contribution to Demand

Solar (Rooftop) 175 13.2%

Solar (Utility) 62 4.7%

Wind 209 15.8%

Hydro 68 5.2%

Battery (Discharging) 13.1 1.0%

Gas (OCGT) 14.1 1.1%

Gas (Steam) 5.0 0.4%

Coal (Brown) 654 49.2% ==> hence Demand = 1,329.3 GWh

Imports 21.6 1.6%

[Sum 92.2% of these OpenElec %s]

Loads

Exports 106 8.0%

Battery (Charging) 17.9 1.3%

Curtailment

Solar (Utility) 27.3 2.1%

Wind 47 3.6%

Net 1,346

Renewables 516 46.1% [OpenElec claimed]

actually 516/1,329.3 = 38.8% [consistent with Coal (brown) Demand]

~~~~~~~~~~~~ OR ~~~~~~~~~~~~~~~~~~~~~

*** Generation ***

Sources GWh Contribution to Generation

Solar (Rooftop) 175 14.6%

Solar (Utility) 62 5.2%

Wind 210 17.5%

Hydro 68 5.7%

Battery (Discharging) 13.1 1.1%

Gas (OCGT) 14.1 1.2%

Gas (Steam) 5.0 0.4%

Coal (Brown) 654 54.4% ==> hence Generation = 1,202.2 GWh

Imports 21.7 **

[Sum 112.1% + imports % would be 21.7/1,202.2 = 1.8% ==>

a total of ??? 113.9% Generation ???]

Exports 106 **

Battery (Charging) 17.9 **

** [no % stated by OpenElec]

Curtailment

Solar (Utility) 27.3 2.3%

Wind 47 4.0%

Net 1,346

Renewables 516 42.9% [OpenElec claimed]

actually 516/1,202.2 = 42.9% [consistent with Coal (brown) Generation]

~~~~~~~~~~~~~~~~~~~~~~~~~~~

So Open Electricity have changed how the interface presents the summary data, and now if you select *** Generation *** [the default is Consumption, so you have to select the non-default] the % 'renewables' presented is consistent with the Generation value that can be derived from the dominant source = Coal (Brown) 654GWh 54.4% ... but that 54.4% is consistent with a total of 113.9% of contributions of sources of Generation...

Which is NOT balanced by the total of Loads:

106 export + 17.9 battery charging = 123.9 GWh / 1,202.2 = 10.3%

So that leaves an imbalance of about ??? 3.6% ??? of Generation

~~~~~~~~~~~~~~~~~~~~~~~~~~~

So neither option makes consistent sense.
