NACS functional specification

NACS functional specification

Never used a NACS, but I understand it has two high voltage conductors for charging, and two low voltage communication pilots.

One of those "CP" is for the vehicle to talk to the charge point, and the other "PP" is to ensure the connector is latched and locked before high voltage is presented.

So I *think* that's a new solar record today 14416 MW but the adjudicators will have to have a good look at it...

just a squeak over the previous record 14414 set only a few weeks ago!

Will it? Won't it?

Think today is the first time in a couple of years that so much of the nuclear fleet is not broken!

Biomass Idk but I imagine some of that is municipal waste that runs regardless and some of it is subsidised and also runs regardless.

@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

Jet fuel shortage fears spark call for 'rationing' plan The war in Iran and the Strait of Hormuz blockade are prompting issues for airliners.

Well, glad you are happy with your combi oil boiler, but remember that heating oil is kerosene, the same as jet fuel.

Hope you have enough supplies and don't get rationed.

You realise that you won't get such low oil prices again, until Hormuz is open? The economics have changed on their head.

How much did you last pay for oil, in pence per litre?

It's 120-130 p / litre at the moment, so 14p per kWh of heat output

Heat pump currently costs 7p per kWh, but less on a specific tariff

Time to check the sums again?

Are 'breaking the link' and 'reducing bills' the same goal, or really two different ones?

Many of the ROC generators were built around 2010-15 when electricity was around £35, which is £65 in 2026 money.

If they can make £86 today before entering windfall tax then they're doing ok! And they have been since 2021.

A lower threshold would 'encourage' them onto a lower CfD strike price.

How much oil (+ refined products) were already in transit when the war started, in tankers sailing across the sea?

They have still been arriving until recently, so delaying the timing of production-stopping working through the supply chain to consumption-stopping.

IDK how big/small?

A Net Zero RAF by 2040 The RAF are on a mission to reduce carbon emissions and achieve Net Zero by 2040.

Wonder what the military think about it?

Guess that depends if gas prices stay up or go down?

If the latter, CfD will be more expensive for bill payers than wholesale. If the former, then EGL diverts generator income to HMT.

So 'de linking' gives better stability for bill payers but possibly at greater cost.

To keep the gas stations available, the sum of their (wholesale plus balancing mechanism plus capacity market) revenue must stay high enough.

Hopefully their BM revenue decreases as grid reinforcement and batteries take over?

So wholesale prices have to rise, in the fewer hours they're running?

"Other announcements include an additional £100million for the Social Housing Fund, to help pay for 57,000 rooftop solar panels for households this financial year."

As I understand today's announcement, we will still pay RO top-up, as the CfD element will only apply to the wholesale price.

Ofc 75% of the cost of RO was moved from bills to taxes about a month ago - seems much longer!

That's right - Ofgem set the price caps based on a 'basket' of spot prices and futures prices. Those are just the sum of the prices charged by all the different generators who are online, or expected to be.

Then, Ofgem include the stabilising effect on CfDs (usually extra cost, sometimes a saving)

Is there any estimate how many of those hours of gas generation will be due to high wholesale market price, and how many will be due to odd gas stations here and there being paid to turn on by BM because of grid constraints and stability?

CP2030 (fwiw) intends <5% of gas power 🤷

This is double edged of course, on days like today when the spot market is very cheap because of solar, we'll still have to pay the higher fixed prices.

2 days ago 1 0 1 0

If I understood it, yes, the spot market price will still often be set by gas. But the price that the consumer pays, will include less spot market energy, and more energy that has been bought at fixed price.

A few months back they brought in grants for air con units, that are great in flats. You can run it in reverse and it blows out heat.

2 days ago 1 0 1 0

They also announced increased grants today, for oil heated homes to switch to heatpumps

They're not reducing the £82 threshold ?

That's still quite a windfall.

Presumably the price of the WCfD will have to be quite high, to compete with this?

Options for zonal locational charges - ofgem https://www.ofgem.gov.uk/call-for-input/locational-charges-and-regulatory-siting-levers-under-reformed-national-pricing

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!

Grand Coulee Dam - Wikipedia

Thats an amazing wind farm! Are we sure it's the biggest renewable energy project in the US? This hydro scheme looks pretty big too.

100% of the times I have got married, I got there early, to be sure of not missing it.

This probably means I've wasted way too much of my life, just standing around nervously in a church.

If I'd traded on risk and probabilities then I could have optimised all that wasted time right down.

In 2026, every electric Ford Pumas comes with the same acceleration as did the most souped-up hot hatch of the 80's Escort range, the Escort RS Turbo

0-60 in 8 seconds, if you liked that kind of thing and could afford it!
