I wonder how local transformer protection equipment will respond to current not going in the direction it was designed for. I bet older stuff like P&B Golds would be less affected, but not so sure of some of the early 'electronic' relays.
I'm sure the local DNO will decide if it's a Vehicle-to-home installation or a true vehicle-to-grid export.

The former wouldn't require any infrastructure change, it would just reduce the evening peak load per home. Increasingly important as cooking and heating move towards electric.

Evanivitch: "Why would you describe a technical discussion from 2018 as "now", "legislative changes" and "in the works"?"

Somewhere in the stuff I scan-read (so many acronyms!) there was mention of this being enacted in April of this year: maybe "near future" would have been more accurate than "now". It is a change to the legislation that is proposed. As you say, it has been under discussion for a while and is nearing enactment; that's "in the works" to me.

Seems there are some massive assumptions in these scenarios, like 65 % of homes using hydrogen for heating.

Residential consumers better prepare for some hefty costs, as they are a main focus of the net zero folly.

There is a reason it is called "net zero" not "absolute zero".

Nobody assumes that in the short to medium term we will be able to do without any thermal generation.

Are there blackouts in Germany?

If not, it would appear no one is waking up to this issue, it's been planned and managed that coal, gas and nuclear will manage the winter load when renewables are low.

There is an issue to address energy storage. Batteries certainly aren't the answer for seasonal variations. Various technologies being proposed to fill that gap, but ultimately efficiency will also be key (insulation being a huge part).

Over reliance on wind and solar has serious drawbacks, when nature plays by its own rules, as Texas has found out. It is ironic considering Texas and its fossil fuel production history.

I hope this provides real world evidence about a conservative generation mix for the UK, with the focus on reliable power generation, rather than C02.

I am quite sure Texans are not concerned about C02 production right now, not when it is minus 20 outside and they have no heating or lights. A lesson for the UK.

The oil and gas pipelines to the power stations were closed too. Their entire grid was unprepared. They were 30+ GW short of demand.

It's pretty daft to blame wind in this instance.

30GW!? Someone has dropped a bk. Texas doesn't really 'do' government, perhaps a reason why it happened?

Ah. Lack of building insulation/'turn on/up the AC' mindset?

Looks like electrical heating is common in the state, lots of resistive heating but also where heat pumps are used they haven't been specified for cold temperatures so they've reverted to resistive heating to keep running.

Texas has some of the largest installed capacity for wind in the US, coal or nuclear tends not to have this intermittency issue.

Reliable supply is the first priority, not CO2. This should serve as a timeous reminder for the UK. Global warming does not guarantee warmth.

Was watching a report and a family were taking turns in the car to warm up, it was that cold in the house,
everything was electric, except the car.
if we end up with all electric there will have to be contingency planning if we have blackouts and subzero temperatures.

It’s identified in the article - the wrong turbines. Hence froze. Hence no power

Don’t blame wind power but the accountants and the procurement departments that settled on the turbines.

It’s like crashing your car and blaming the car. Except you were on ice. In P-Zeros

Except in this case its like blaming being late home on a car crash when your using the train.

Did you read my link!? The gas pipelines were closed, the gas powerstations shut down, then the nuclear and coal power stations fell over.

They have 25GW of installed wind in Texas, but they were 34GW short. Do the maths.

Especially if wood burners are banned!

Perhaps we'll all have hydrogen heaters, just in case!

Or diesel generators.
