One of the people here understands that every day we trade off risk of black outs against cost (VOLL etc), and some people may give up some security for savings. The other person does not seem to understand that.
Replying to @KathrynPorter26
I used the actual words "i'm not advocating for blackouts" 5 times. I did point out that they happen at the local level in the UK quite frequently - and that it'd be good to give batteries to people who need continuous supply.

Thinks an expensive distraction, despite what Ubitricity try to sell. 25 A cut outs, earthing issues, 30m apart, some on the back edge of the pavement etc. Lots of public money was spent ‘upgrading’ PL columns, might as well install proper chargers. O&M costs very high too.
This doesn’t look like much, but it changes everything. What you’re looking at is an evpzee lamppost charger. It is the smartest solution to one of the biggest barriers to EV adoption. A standard street lamp, quietly turned into an EV charger. No digging up roads, it is installed in just 30 minutes. No huge infrastructure projects, a full street can be electrified in a matter of hours. Manufactured and assembled in the UK and fully OCPP. Using what’s already there. For millions of people across the UK, especially those without driveways, this is the difference between “I can’t have an EV” and “actually…I can.” It’s easy to overlook innovations like this because they’re not flashy. No 350kW ultra-rapid chargers. No massive charging hubs. Just practical, scalable, everyday infrastructure doing exactly what it needs to do. And that’s the point. The EV transition will be be driven by everyone having the ability to charge when they need to. Simple. Effective.

Came across this in Leavesden today – someone has converted the cupboard under the stairs into a bedroom, sleeping right next to the meter and consumer unit, which has the gas service behind it! I don’t think @UKPowerNetworks will be interested. All muggled up.

How do I bump change my car @OctopusEnergy? The app has changed. I can’t seem to set the target and departure time now in the app, and the ‘bump’ button does nothing. But I need to charge my car now! I have tried over riding in the BMW app. @g__j

HMS Conqueror would like a word.
.@SECWAR “In the Indian Ocean—an American submarine sunk an Iranian warship, that thought it was safe in international waters. Instead, it was sunk by a torpedo—Quiet Death. The first sinking of an enemy ship by a torpedo since World War 2. Like in that war—back when we were still the War Department—we are fighting to win."

@neso_energy have doubled their forecast for future transmission charges. A standard 1 MVA DC EV hub jumps from ~£13k today to ~£37k by 2030 — almost a 200% increase, and ~70–80% higher by May 2026. A factory connection of the same size would see the same hit. (1/5)

Allowed income for NGET, SHET & SPT is forecast to rise from £3.2bn → £12.1bn by 2030. That’s why a 1 MVA site in SE England sees ~£24k/year more TNUoS. Large users face increases in the hundreds of thousands. Domestic bills could rise ~£40 in 2026 and ~£60 in 2030. (4/5)

Will it all happen? Probably not. NESO use the draft allowances mechanically; Ofgem openly flag “deliverability concerns”. Final Determinations will likely scale this back — but even then, we’re heading for a major uplift in transmission spending that few have clocked. (5/5)

The demand queue for UK data-centre connections has exploded — and the scale is far beyond anything in Clean Power 2030, UK Net Zero plans, or any NESO scenario. (1/6)

In short: No national scenario — not Clean Power 2030, not FES — includes anything close to 100 GW of new data-centre demand. The majority of these applications will never connect. (5/6)

To put it simply: We do not need — and cannot power — 350 hyperscale data centres. The queue is now so large that it is fundamentally disconnected from any realistic UK energy pathway. (6/6)

I am not sure the argument of ‘the alternative is worse’ is the winner they think it is.
Lots of noise tonight: "It's absolutely mental, No 10 have started a fire and now they can't put it out," says one minister. Wes Streeting is doing the morning round tomorrow.....

@ofgem figures last week show the demand connections queue has jumped from 44 GW in April to 125 GW in June 2025. That’s almost three times in two months — when UK peak demand is only 47 GW. Something big is going on. (1/6)

To ride through long calm spells we still need gas, nuclear and biomass. Renewables don’t give the dispatchable power needed for inflexible loads like data centres. If we added 10 GW of new demand, we’d need roughly 10 GW of new gas. As well as more for replacemet. (5/6)

So if you’re a data-centre developer: Forget 400 kV — 5 years+ away. There’s room on the distribution network under 100 MW. Stay below 350 MW — N-1 not N-2 - That’s the difference between an £80 m and £150 m connection. Generation, not grid, is the biggest problem. 6/6
