Carbon intensity forecasts now 96 hours?

[andreww]

https://carbonintensity.org.uk/ now says it "provides ... regional carbon intensity ... 96+ hours ahead of real-time", which is, I think, longer than the 48 hours they used to provide. I've not looked into the data that actually comes back from the API, but if we do get four days data we may want to take advantage of this. Hopefully we've designed things so such a change is easy to handle.
