Some solar power assets are being tracked though unfortunately (for now) I'm only able to display data for assets that report on the balancing system in Great Britain. This means most solar has no data that I can easily access.

I hope to work around this soon.

The squiggly ones across the country? Those are the National Energy System Operator (NESO) transmission boundaries for Great Britain. They represent areas of the country that are tracked for the purposes of managing constraints, which is when the transmission network over the boundary can't handle the amount of power flowing over it. When they are overloaded (or rather, before that happens) NESO will step in and "balance" the various zones by turning up or down generators.

Thank you

Thanks!

Yup! I have two ways to do it right now, the first is to click the plug-looking button on the map and this'll switch into curtailment mode to filter the assets that are currently being turned down due to transmission constraints, as well as the assets being turned-up elsewhere to balance things out. Also if you click on a curtailed assets you'll see the curtailment as a yellow area on the charts.

The other method is to visit my dedicated page [0] for tracking aggregate curtailment and turn-up, plus the costs for this.

Do you approach coal power stations or oil rigs with the same level of scrutiny? I'll wait to hear back from you on the long list of environmental damage they cause. In your own time.
