> Power plants like coal and nuclear are slow to change
Pointing out we have no coal power stations in the UK. We have lots of CCGT and a few OCGT and they are used to meet rapid demand spikes. There are also some pumped hydro which are also used for such rapid responses.
The problem with nuclear is the regulations etc are stuck so much in the past it takes an age to simply start building one. Past governments have simply let the old sites whither and close, or allowed an extension after a bit if spit and polish. No new nuclear was built, none. So we are stuck in a situation where several of the few remaining sites/reactors will close before Hinckley Point C even starts being commissioned. Pretty standard fayre over here.
> One way to at least relieve the situation quite a bit is to run batteries at every installation to smooth out the day to day production/consumption
Sounds nice on paper but will never happen. Also trying to convert UK houses to multiple phases will never get off the ground. Consider that energy companies have failed to manage to force everyone to install a smart meter, so they risk getting fined for not having installed them, but the regulator would smash their knuckles should they actually make smart meters non-optional. I'm one of the holdouts. I get calls, SMS, emails and post all telling me "it's time to upgrade" and it will "save me energy" blah blah which I know is a con. What saves energy is not using it. Nobody ever needed a smart meter to do that. We have these amazing things called s-w-i-t-c-h-e-s and I've never known anyone not to switch off the wall socket of devices that shouldn’t be on! So it turns out that it'll save a few hundred quid a year, but that makes just a few quid a month if that. Wow. If they design the SMETS 3 meters correctly (unlike the burning pile of dog shit that was the current meters), I may bite.
So as they can’t get us to upgrade, they have zero chance re-gigging the entire house for multiple phases. They don’t need to anyway, it’s all done at the substation. Most UK housing are ring mains so you'll have to employ teams of people to enter EVERY property in the UK and literally re-wire the house, FOR FREE. It has to be free as nobody today is going to pay to have it done.
Batteries? Heck those aint even free so they are a dead end. Considering that for the majority of housing they will be not permitted as they will be *considered a fire hazard*. So you'll only be able to target detached housing, perhaps semi-detached and likely will have to wait till sodium batteries become the norm so wont explode and kill your neighbours. Who will pay for it again? In a country that won’t install heat pumps because it'll cost at least 10 grand (not to mention you can only install them in non-terraced)...
You see the problem. It amazes me that somehow in the past this country managed to rustle up workers and pay them to *actually enter people’s homes* and convert their gas appliances from town gas to LNG, for FREE.
But today, none of that is possible so this sort of thing just is normal:
1. Installation of smart meters has low uptake.
2. Upgrade of copper phone lines to fibre has been delayed multiple times and is now on pause pending government review.
3. Heat Pumps are pushed to a public that can’t afford to install them and rarely live in a property that can LEGALLY have one installed.
4. Electric cars are peddled to a public that largely live in housing that has no off street parking and thus cannot charge at home. Charging at home is ideal as VAT on leccy is fixed to 5% there, but public chargers have 30% VAT on leccy plus additional costs.
5. To use a heat pump, and to save energy in general, you need to insulate. Grants exist but most people:
5.1 Dont know they can add insulation.
5.2 Have a land lord that doenst know.
5.3 Have no money to do it, even with the grant.
5.4 Have no time to do it as they are too busy working their socks off to pay the bills.
5.5 Cant get the grant as they dont qualify.
My Uncle cant work. He has had multiple strokes and is registered on the energy priority register, which means no matter who the energy supplier is, he should be top of the queue for resolution of issues. The house he and his daughter live in had a working boiler till TWO years ago when it practically blew itself up. It was fixed, but couldnt handle running more than a few weeks before it died again, at which point the gas engineer condemned it. They spent two years, TWO years with NO hot water at all, nor any heating. TWO winters with fan heaters and boiling a kettle to wash with.
He didn’t qualify for an insulation grant, nor for a grant to install a new boiler. Even though he had no income, was unable to work, was on Universal Credit and other benefits. Forget a heat pump, they couldn’t afford the £1000 to install a new boiler, you think they'll and others like them would fork out the £10,000-£14,000 needed to install a heat pump that won’t work in their old uninsulated house?
You see the problem?
To fix it, you'll need a government that will look beyond their guaranteed 5 years. They will have to fix the current economy and save money to build a government funded force of installers. You want multi-phase leccy? Or batteries? In every home? Well that massive undertaking will be a multi-decade project which will have to handle "real life (tm)". Homeowners not being home when they were supposed to be, only being home when you are not able to turn up, can’t be home for the second day that you need because you found a big issue with that particular house.
I wouldn’t want to run such a massive project. It would probably drive me insane.
