es.catapult.org.uk/insight/heat... Gas networks have to plan for cold weather heating demand, but electricity networks don't (yet). Data from 100s of UK homes in our Living Lab shows how electrifying heating makes electricity demand vary in cold weather, and why we need to start planning for this.
๐โก The emerging EV overnight demand peak: how time of use tariffs create herding behaviours as EV adoption rises. At ~50% EV adoption, our Living Lab data shows overnight EV demand will be 2x the current evening peak, so we'll need new ways to smooth out demand. es.catapult.org.uk/insight/the-...
Youโre doing great Fionna!
Apologies - Fionna not Fiona!
Hi Fiona! I run the Living Lab at @energysyscat.bsky.social . Great to hear your experiences of our A2A heat pump trial and thanks for sharing it here! We've received your emails and the team will be replying shortly. Best, Claire

Our previous work showing the same issue: EV Energy Taskforce - evenergytaskforce.com/charging-the...; CVEI es.catapult.org.uk/case-study/c...
Right now, the number of UK homes with EV charging is around 3%*, but this will rise. ๐ช๐ฒโ๐น๐น ๐ฒ๐๐ฒ๐ป๐๐๐ฎ๐น๐น๐ ๐ต๐ถ๐ ๐ฎ ๐ฐ๐ฟ๐ถ๐๐ถ๐ฐ๐ฎ๐น ๐บ๐ฎ๐๐ ๐๐ต๐ฒ๐ฟ๐ฒ ๐ฐ๐ต๐ฒ๐ฎ๐ฝ ๐ผ๐๐ฒ๐ฟ๐ป๐ถ๐ด๐ต๐ ๐ฐ๐ต๐ฎ๐ฟ๐ด๐ถ๐ป๐ด ๐ถ๐ ๐ป๐ผ ๐น๐ผ๐ป๐ด๐ฒ๐ฟ ๐๐ต๐ฒ ๐ฏ๐ฒ๐๐ ๐๐ฎ๐ ๐๐ผ ๐บ๐ฎ๐ป๐ฎ๐ด๐ฒ ๐๐ฉ ๐ฑ๐ฒ๐บ๐ฎ๐ป๐ฑ. Weโll need charging systems that smooth demand across the day. (see links in replies)
The pink profile on the graph shows only the homes from the same group who have told us they donโt have an EV or charger (though a few may have EVs that they havenโt told us about). The big daily demand peak is 17:00-17:30, as weโd expect, with low usage overnight rising from 05:30-06:00.
We see a notable spike at 00:30, when Octopus Goโs cheap rate kicks in, and a big dropoff at 05:30 when it ends. We also see lesser effects from other EV tariffs. Most people charge their EVs 2-3 times a week, but some Living Lab homes have more than 1 EV, so may be charging more often.
The blue profile on this graph shows electricity smart meter consumption from 854 homes, for a week in November, in our Living Lab. Of those, 408 have told us they have an EV or home charger. ๐ง๐ต๐ฒ ๐ฏ๐ถ๐ด ๐ฑ๐ฎ๐ถ๐น๐ ๐๐ฝ๐ถ๐ธ๐ฒ ๐ถ๐๐ปโ๐ ๐๐ต๐ฒ ๐ฒ๐ฎ๐ฟ๐น๐ ๐ฒ๐๐ฒ๐ป๐ถ๐ป๐ด ๐ฝ๐ฒ๐ฎ๐ธ. ๐๐โ๐ ๐ถ๐ป ๐๐ต๐ฒ ๐บ๐ถ๐ฑ๐ฑ๐น๐ฒ ๐ผ๐ณ ๐๐ต๐ฒ ๐ป๐ถ๐ด๐ต๐, ๐๐ต๐ฒ๐ป ๐๐ฉ๐ ๐ฎ๐ฟ๐ฒ ๐ฐ๐ต๐ฎ๐ฟ๐ด๐ถ๐ป๐ด.

This is what consumer electricity demand looks like at about 48% EV adoption, with current tariffs. The new daily demand peak is in the middle of the night, and itโs twice as big as the current evening peak.
What if homes could have >1 electricity supplier for different uses, like EV charging vs the rest of the home? Would this unlock innovation, & fairer ways to reward consumers for flexing demand? Or just add unnecessary complexity? Weโre running a trial to find out: es.catapult.org.uk/project/brea...
Do you live in a UK home with electric heating (old style) and a smart meter? Sign up to take part in our new Living Lab trial and get a new, free heating and cooling system, plus other perks. This is a gov funded trial studying decarbonisation pathways for different types of UK homes. Please share!
