Something big happening on the Dundee waterfront! Inch Cape turbines arriving for assembly, Vestas 15MW www.inchcapewind.com/inch-cape-fo...
Great to see these battery trains, which will run electric over the Pennines and then on battery out to the Yorkshire coast towns. Avoids using diesel on the quieter lines that haven't been electrified yet. But don't understand all the hype that these will be a 'UK first' when delivered in 2034.
Private operator First Group (trading as Lumo) ordered 14 bimode trains in 2024, some of them battery hybrids. Might operate the London to South Wales line, continuing out beyond Cardiff where electrification was controversially stopped.
Battery commuter trains already running in Merseyside and West London

Private operator Grand Central are doing the same thing from 2028, on the electrified line from London to Yorkshire and continuing in battery/diesel hybrid mode to Bradford and Teeside
Hitachi have been running a trial unit since 2024 www.modernrailways.com/article/uk-f...

We are doing, that's the problem. Several big power lines in N Scotland are shut down while they are being upgraded to 400kV. It's like upgrading a motorway or railway, if we want the extra capacity then we have to put up with years of roadworks and delays while building it!

I remember when being actually paid money to use more electricity was surprising, weird, noteworthy, we had discussions about who was going to bake cakes or charge the car. That was like, last year or something Now it's just... normal 😎 bsky.app/profile/ener...

It's 2026 and Ofgem are still telling people to buy halogen and CFL lights ?!? Can you even still buy those any more?
Three top tips for reducing your lighting bill: ↔️ Swap out your incandescent filament bulbs with modern LEDs, CFL or halogens 🌆 Turn off the lights when no one’s in the room 💡 Motion sensors are a great way to ensure you are only using lights when you need them

The new bill for electricity after July is actually _less_ than the present April bill, because the fall in consumption has more than compensated for the rise in unit rates! electric bill component: April £796 for 2700kWh July £783 for 2500kWh (For London - costs more in the North!)
Michael de Podesta found his aircon usage in London correlates well with days when his PV generates plenty of power to run it. The aircon is still needed after the sun goes down, so PV energy stored in his home battery is used to keep it running.

1/ Published today in @natcomms.nature.com: our analysis on long-duration electricity storage needs for coping with #Dunkelflaute events in 🇪🇺 . Joint work with my stellar @diw.de colleagues @kittelmartin.bsky.social (lead) and @aroth.bsky.social 🎉https://www.nature.com/articles/s41467-026-72681-5
@stockfttp.bsky.social what is the record low ccgt again? Also, @robhawkes.bsky.social that is remarkably little curtailment? - it's windy in England but not in Scotland - sunny everywhere. Looks like a couple of CCGTs are on tickover for voltage/inertia
Ofgem's consultation on how electricity transmission might be charged based on location, after Zonal pricing was dropped NESO are also consulting, and perhaps DESNZ will launch theirs tomorrow! www.ofgem.gov.uk/call-for-inp...
Got no horse in this race but the physics of cooling satellite data centres are interesting, a discussion here. My fagpackets seem to match up with some of the actual experts! Every kW of sunshine that lands on a satellite has to be reradiated, this has been solved for small satellites since 1957.
Skeptics need to drop the cooling issue. The existence of ~10,000 of these ~10 kW OAP satellites proves that we know how to generate/reject power/heat in space at scale. Focus on the economics. The logistics. The launch costs. But drop the radiator issue. It's silly. bsky.app/profile/maxf...
Air temperatures ⁰C in our hallway. Warm air is flowing rightwards along the ceiling from the kitchen (been baking) and exchanging with cool air flowing leftwards at floor level from the stairwell. The house thermostat is set at 20 and is trying to make any kind of sense of all this.
protonsforbreakfast.wordpress.com/2026/01/06/v... In my home, "room temperature" varies considerably with height. It might be so in your home too. In which case, take care where you place your thermostat. Best wishes Michael

Saw this chart from Ben Watts (his real name, I think) about different time profiles of European electricity consumption. Fun. www.linkedin.com/in/kilowatts/
