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.

The emerging EV overnight demand peak - Claire Rowland As EV adoption rises, current tariffs which incentivise consumers to charge overnight are creating new peaks in home electricity demand.

🚗⚡ 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-...

You’re 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

Electric Vehicle Energy Taskforce Energising Our Electric Vehicle Transition

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. 𝗪𝗲’𝗹𝗹 𝗲𝘃𝗲𝗻𝘁𝘂𝗮𝗹𝗹𝘆 𝗵𝗶𝘁 𝗮 𝗰𝗿𝗶𝘁𝗶𝗰𝗮𝗹 𝗺𝗮𝘀𝘀 𝘄𝗵𝗲𝗿𝗲 𝗰𝗵𝗲𝗮𝗽 𝗼𝘃𝗲𝗿𝗻𝗶𝗴𝗵𝘁 𝗰𝗵𝗮𝗿𝗴𝗶𝗻𝗴 𝗶𝘀 𝗻𝗼 𝗹𝗼𝗻𝗴𝗲𝗿 𝘁𝗵𝗲 𝗯𝗲𝘀𝘁 𝘄𝗮𝘆 𝘁𝗼 𝗺𝗮𝗻𝗮𝗴𝗲 𝗘𝗩 𝗱𝗲𝗺𝗮𝗻𝗱. We’ll 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 don’t have an EV or charger (though a few may have EVs that they haven’t told us about). The big daily demand peak is 17:00-17:30, as we’d expect, with low usage overnight rising from 05:30-06:00.

We see a notable spike at 00:30, when Octopus Go’s 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. 𝗧𝗵𝗲 𝗯𝗶𝗴 𝗱𝗮𝗶𝗹𝘆 𝘀𝗽𝗶𝗸𝗲 𝗶𝘀𝗻’𝘁 𝘁𝗵𝗲 𝗲𝗮𝗿𝗹𝘆 𝗲𝘃𝗲𝗻𝗶𝗻𝗴 𝗽𝗲𝗮𝗸. 𝗜𝘁’𝘀 𝗶𝗻 𝘁𝗵𝗲 𝗺𝗶𝗱𝗱𝗹𝗲 𝗼𝗳 𝘁𝗵𝗲 𝗻𝗶𝗴𝗵𝘁, 𝘄𝗵𝗲𝗻 𝗘𝗩𝘀 𝗮𝗿𝗲 𝗰𝗵𝗮𝗿𝗴𝗶𝗻𝗴.

Breaking the one supplier rule The WESA secondary supplier trial is designed to explore innovative approaches to energy regulation.

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? We’re 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!
