> Regardless, this is incredibly neat, and I'd love to see this kind of data for the grid that serves me (Eastern Interconnect in the US) -- are you aware of any sites similar?

(for most US grids, ElectricityMaps consumes somewhat delayed EIA Balancing Agency generation mix data from https://www.eia.gov/electricity/gridmonitor/dashboard/electr... ; their data is mostly live for system operators that provide live data on their own website, CAISO in California and ERCOT in Texas, for example)

Very cool! This is fun to watch.

Now I'm wondering how residential rooftop solar is accounted for... presumably there are houses in these grids which export solar electricity or offset grid power with solar production. The utility supplies data to this site, and the utility would only know about the energy produced by residential solar if each KWh of exported or offset energy were reported somehow. I'd imagine that's a pretty tough problem, particularly in the offset scenario.

In Australia [1], a data provider (APVI [2]) collaborates to provide this data in the aggregate, and so it can be surfaced distinctly as rooftop solar. In the US, it manifests as reduced demand (“behind the meter generation”) during daylight hours.
