I did appreciate, but I am not responsible, it is not my call [...]

Hmmm.

That's like saying that Climate Change doesn't fall within my remit!

If residential use of electricity is accounting for 10% losses at the local substation, then there's a sizeable proportion of the UK population who would like to reduce those losses.
The reason they don't currently use electricity in a grid-friendly manner is because they're unaware of the issue.

Readers of this forum will hear about the problem of course...
... and what they can do to alleviate it. 😊 

 

UKPN have little interest in tackling the problem because they can make vast amounts of additional profit by upgrading the substation transformers for high capacity units.
Under the present RIIO-ED2 Agreements with Ofgem, that is regarded as a satisfactory 'solution'.

It's not of course.
The same amount of energy is lost due to phase imbalance,
but the newer/larger transformer doesn't get so hot because the oil-based cooling system is more effective.

I've asked NESO to add initiatives for Losses Reduction to the forthcoming RIIO-ED3 contracts.

@transparent , I am not saying I do not care. Just that I do not consider my own individual response could ever be appropriate.

I am also not one that applauds when youngster get over concerned about climate and make major lifestyle changes. Like live on a canal boat and not have children to reduce their carbon footprint..

There are answers, hope that NESO does something about loss reduction. But as an individual, I should be expected to sell if someone buys at a suitable price? And only do it if I do not need the capacity at the time (and in case I see it as economically viable)? Whether it is lost or not is in fact something that others can respond, my response would be suboptimal. Whatever my DNO asks me to change, since I understand the limits of current market setup, I will accept some inconvenience to make adjustments.. And so I am grateful for you taking the time to explain it! 

Overall the situation of selling power that goes to waste is not dissimilar to selling your car and the buyer not using it and keeping it in their drive for ever. Why should the seller feel guilty?  

And I still think it is better that people seek the flexibility to be able to export than keep the spare electrons in their house? 😉

I live in a rather rural setting and problems for the last few months with the local substation mean UKPN have rerouted power to keep the lights on. However, the present situation means any time my home is operating differently from normal households (e.g. exporting back to the grid or importing heavily enough to charge the EV), whatever I'm doing has a significant effect on the grid voltage. That affects not only my home but that of my neighbours too. I did see times during July, August and September where the voltage was high enough my inverter had to stop exporting. I have seen times in this past month or so when the voltage has been dropping to 185 or so.

My point? My individual response can and does have a significant effect. To think otherwise would just mean I'm ignoring my personal responsibility.

I agree. I live in medium density suburban setting, so I guess people like us end up paying for everyone to have electricity on tap.

On an emergency I would do the same as I have the time to. But I would not expect my dad to do the same not my daughter just starting her job as well.. 

Ukpn had a few issues a few years back with a power station that was leading to frequent blackouts. I worked with them and eventually they replaced it.

I think you miss the point, @batpred. What I may or may not be doing isn't because of any emergency situation; all I'm doing is recognising that what I do as an individual has an effect at local level for my neighbours. That 10% loss due to imbalance is, as @transparent said, at the local substation, so your individual response carries a significant weight.

Is the national 10% figure quoted somewhere @transparent? I assume you are looking at a different figure than me?

The government  gives a breakdown for total losses for 2024 at 9%, broken down as:

Transmission losses 8,572

Distribution losses 17,426

Theft losses 2,119

Total  losses 28,117

I assume the local substation losses you mentioned are in the Distribution figure?

In my case, my voltage reads are now 240V. They should be 230V, so should I consume less? 

I see your point is to adjust on a personal level, but I am concerned that by letting UKPN believe that is an acceptable service, they are not doing what they should to correct it.

My inverter is set to use G99, so it would also automatically stop exporting, etc according the the normal rules expected.   

But 185 volts on your network is not acceptable, what has UKPN's response been?

No. There are already acceptable limits quoted and variations within that are to be expected.

However, if I had historical data showing consistently high voltages during the summer months, I would feel it irresponsible of me to follow an "export first to maximise profit" strategy rather than a "minimise import by using as much home-grown as I can" approach. Please note, I am talking about me and my situation not you and yours but I still underline the point that each individual's actions can have an appreciable effect on those directly around them.

I agree. I do not think UKPN - or any other DNO - should be let off scot-free. They have a responsibility as well and should be made to face up to it. However, what each of us does is not a binary choice. It's not a matter of either we adapt our behaviour or the DNO fixes the problem; it's a combination of both. UKPN's helpline is starting to get to know me quite well now, so I'm not making it easy for them to ignore the problem. However, I am making it easier to solve the problem - in this case by providing historical data and being open and accurate with the network engineers who visit - and I am doing what I reasonably can to avoid causing problems for my neighbours. In other words I'm trying to take personal responsibility for what I can influence and applying pressure to UKPN to resolve what I can't influence myself.

Once again, we come back to the same point; my individual response can and does have a significant effect.
