The proof will be in the pudding...just no pudding atm.
Living in a village we also suffered short power cuts for years, slightly less frequent once changed to abc, was mostly caused by lightning there.
You may be right Rooky. Let's hope the sales experts at AFC can convince them of that!
Several times a year, our village and surrounding areas have suffered ever increasing power cuts, often weather related.
These power cut increases appear to follow the increase in housing that is taking place.
On talking to a technician from the electricity supplier, I was informed that it was manly the problem with the main infrastructure, plus the sub stations not being able to cope with the ever increasing demand.
On rare occasions, these power cuts can last up to a couple of hours, not ideal if you are home charging your EV for the next days use.
With the take up of EV's growing month on month, independent off grid charging has to be the way to go, especially for the block customers, such as transport, fleet delivery and the like.
Cables are manufactured and rated based on the network distribution voltage. They don’t make them to cover all voltages..
As I’ve said before, I used to install large electrical installations in London which included applications for supply from the electricity provider. Even back in 2007 I had difficulty getting the intake capacity required. We supplemented with CHP units to provide electricity and heat for hot water from gas powered units. There were also subsidies at the time for operation of these units.
Whenever I used to see news items regarding fleets changing to EV's, plus the talk of shipping and the possibility of flight converting to electrical power, it always gave me an uplift concerning the future for AFC.
I have to admit that similar news items, now tend to depress me as far as AFC are concerned, especially when these articles are linked to EV charging units that are linked to other EV charging companies.
If/when AFC do start to sell their EV charging units, no doubt my feeling regarding conversion from burning fossil fuels for propulsion/energy to EV's will revert back to a more positive feeling.
@task, whilst you can reduce losses by raising voltage, cables will only be rated to a certain voltage, so you still need to replace the cables to put more power through. You might be able to stretch the spec a bit but all of the transformers will be fixed ratio i.e. one voltage to another, and working the cables closer to their limits would only be a tiny increase anyway.
18p is a bit high... I think fit prices will have to change, daz is right the car can be the storage too, Nissans chademo were ahead of the game with bi-direction, Outlander can already do it but has small battery.
Das, not all cars can do that, a leaf can though.
Task, when your paying 18p a unit and receive 3p it’s not an equitable situation.
You pay your standing charge for the network costs then the feed should be offset at the price while importing. Maybe minus a small percentage.
When I eventually scrap my diesel and buy an EV i'm hoping i'll be able to charge it from my solar panels and then use the power from the car in the house as my annual mileage is very low, then I won't need a 2nd battery for solar storage.
I personally don’t think it will flow in both directions, the feed in price doesn’t support the case. Homes will fit battery storage and reduce their import.
Chippyo, understood, you think NG are wingin'it ? maybe...... its hard to fathom just how the network will look in a few years with more power flowing in both directions ... I need a crystal ball uprade. Seems like price wants to test 20p again imo...the markets are taking a beating today and maybe more to come from usa stupid handling of covid fallout.
Cables......iPad does my head in
Task, cackles are only one part of the issue. Distribution network has switchgear, transformers and isolation which would all also need upgrading.
In my view NG is being optimistic and will at some later point say demand has been unprecedented and we require government money to assist in infrastructure expansion.
@13th, talking In terms of existing cable capacity, (that will be unable to cope allegedly ~ some will some wont) The higher the volts the same power (watts) can be delivered through smaller cable sizes, its why pylons are 33kv ... ab & pollard comparisons to "same power as a housing estate" are a flawed argument, its the same power but other than that ~ its not the same at all ~ just sounds impressive and shows a lack of understanding a bit amateurish imo.
Taskmaster, it's still Watts and Kwh, regardless of voltage, you've got to make the power somehow.
Bananaman, yes but it also depends on the system voltage. if they're using higher volts then less amps...more efficient.
They're also using Zenobe Energy for grid balance, where will afc fit in ? lets see.
382kw battery. Try charging a fleet of those in an hour.
Wow. That would be a massive energy pull.
Even charging over night would still require 50kw charger available for each bus. That would take 7 hours.
Grid would certainly not cope with those requirements or rates without a costly upgrade.
That is the way things are going.
