Might be of interest.

Most do ship DDP ( delivery duty paid) but always confirm

An NI based installer who visited me to finalise install details was of the opinion that only a very small percentage of homes would be able to have dynamic tariffs enabled, he said we're several years behind the UK in roll out.

No idea why he would think only a very small percentage of homes would be able for dynamic tariffs. You obviously need a home battery, but that is pretty much standard with any PV install these days

He is right about rollout though. Dynamic contracts have been available in the UK for years. Here you can't even get one yet. And because of the wholesale market here, the dynamic tariffs will not be interesting for years to come. Currently the wholesale rate is rarely below 10c / kWh. We would pay a surcharge of a few cents minimum on top of that. So about 12-13c at best. Currently I pay less than 6c / kWh incl VAT. And get 25c / kWh for export. I would rather keep that 😁

I agree, looking at the wholesale market right now, I wont be giving up my cheap night rate either.

Will watch it, and if it suits me financially i'll move, and i can build the automation to take advantage of it too.

Given that wholesale rates down 75% from a year ago ( rte news), so they're a quarter what they were a year ago, its strange that my 24hr rate is up 15% on a year ago.

In the dynamic tariffs. He said it wouldn't be available to them, whether because utility companies and resellers have to ramp up, or because some technical upgrades need to made. There's probably little appetite in the public for them, so it might not pay the admin cost for a provider, assuming there was something in it for them as well as the consumer. On the one news, an industry commentator pointed out that 55% of the average consumer bill is not for consumption at all, it's for the standing charges, levies, and taxes. I was shocked, mine is not that bad, consumption is 64% to 36% charges, but we cook on electric. A lot of people cook on gas, their leccie charges would easily pass out their consumption

But if on gas, theres a standing charge for gas connection too!.

bonkers uses the average consumer use that everyone uses if you select "you have just moved in/dont have a supplier)

Cheapest one is yuno, as an example 1253.65 annual bill of which standing charge is 257.21, which is 20% of the bill.
PSO works out at 2% of the total bill and VAT is 9%.

thats about 30% - thats a long stretch to 55% so a few truths are stretched.

Once you get solar in, you'll be looking to try and get your bill negative next!

My farm Electric bill has gone negative. Not an issue with tax as it is counted in the years accounts.

On the dynamic "time of use" tariffs they were due now in October but the utilities asked for an extension to the October deadline for roll out. Possibly 6 months extension I can't recall.

So I get that things can be hard to figure out sometimes, but I'd like you all to imagine going to the bank and asking for a 6 month payment holiday on your mortgage without any interest building up

Or asking Revenue to just not pay any taxes for a while because taxes are hard to pay

Yeah, I imagine we'd all get the same response somewhere between "no" and "f**k no"

However if you're an electricity company then apparently rules are for other people 🙄

I'd have no issues if they never enabled it. We all thought smart meters were going to give us the opportunity to use a cheaper rate and save a few quid, but as you see, only the middle of the fkn night went down, while day went up and peak went up-up-up

The way smart tariffs were brought to the market was a disgrace. Higher standing charges and much much higher unit rates.

I've benefitted from exporting though. For a while I was on non smart tariff (unactivated meter) and getting payed the Feed in Tariff 😀

Busman Paddy Lasty · 24-10-2025 06:17AM

If they were fined for every day they were late it would look a bit professional. I'm not hopping mad over it because the time of use prices will probably be a rip off anyway!

paulbok · 24-10-2025 09:32AM

Will definitely need to increase my battery storage before it comes in.

Dynamic pricing its on the roadmap for roll out this year, you obviously don't need a battery. it works for people without batteries too. they just load shift the washing machine, dryer etc

https://www.boards.ie/discussion/comment/123932314#Comment_123932314

that is how the market works, cheaper at night. more expensive during the day. before smart meters you were paying an average of the 2.

Which to add people on day night or night saver meters if your old enough, used.

Alas, gone are the days of 6-7c night for 9 hours and 14c day, that's what it was when I got mine (and the ev) in 2020!

I think 24 hr day was like 12c

Of course it "works" for anybody. But to make the most of it, you need a battery. With my current setup on a 5c/kWh 3h slot non-dynamic contract with Pinergy, I make about €2000 per year on my electricity bill. With the exact same setup and a dynamic contract in the Netherlands, I would make about €10000 per year. Both with fully automated export / trading setups

Based on current Irish wholesale prices, I wouldn't make a cent here with a dynamic contract. Probably make a loss. Like 99.99% of other people LOL

ECO_Mental · 24-10-2025 12:22PM

I think we were all surprised here with the FIT rates we got from our suppliers...we were expecting 5-6 cent saying irish suppliers will shaft us etc etc and to all our surprised we got 15 cent+ with top rates now at 25 cent.

I am hoping that we will be surprised that dynamic pricing might work out better than we think..

If you just go on the daily settlement prices then yeah there is nothing exciting in there...where the action is at is the balancing markets where unit costs can be very high and low!! and can go negative. Potentially this is where the action is at.

Its a complex market the SEMO and not easy to understand or get any useful data but im hopeful. I will be prepared 29kWh of battery and a 15kVA inverter being delivered next week.

But we have Pinergy to fall back on anyway 😋

there has been significant price rises since then across all rates

Agree on the FIT rates. But unfortunately there is no hoping about dynamic pricing. It is simply the wholesale rate plus a mark up for end users.

Even if the latter was zero, the wholesale rates in Ireland are not cheap and there is no big fluctuation in the rate. Which is the very thing that makes dynamic pricing so attractive and profitable for people with big batteries, EVs, V2G, powerful inverters, etc.

In other words: being able to buy big when price is low or negative an being able to sell back big when price is high. Not much profit in that if the price is around the 10c / kWh mark most of the time. We want negative 40c to positive 100c / kWh, switching all the time 😎
