    Total newbe about smart meters,I am on the normal standard electric plan with bord gais, a smart meter was installed a year or two ago but I never moved to a smart plan. If I change to a smart plan is it a simple online application or is there some activation process involved?



  • Registered Users, Registered Users 2 Posts: 10,102 ✭✭✭✭CoBo55


    Sign up to esbn to see if your meter is transmitting data to them. If you can see your usage data everything is working as it should and signing up a smart plan will be easy.

    I am with flogas for electricity and have a day night meter, does anyone know the limits you get charged more for electricity? e.g. if you use over 2000kw per 2 month you get charged more etc

    I was in the same position. With Bord Gais on dual fuel and had a smart meter fitted last year and didn't activate it. I signed up to esbnetworks last year to get the data from it so i had some idea of my usage.

    When out of contract with BG in September they weren't offering anything decent to me so i moved to a smart plan with Energia. No issues with the switch. Just done it online and got a letter from ESB networks to say the smart meter was now activated. There are plenty of 24 hr single rate plans available on smart meters now if a Time of Use doesn't suit.

    To be honest if you don't have an EV or a PHEV there doesn't seem to be a reason to have cheap night electricity as you won't be able to switch enough power usage to night time to make up for the higher day rate.

    Obviously people with heat pumps, storage batteries etc are different but for the bog standard household with gas heating and no solar etc you really need an EV to make use of cheap rates.

    Charging from 10-80% in effect is a 70% charge.

    So…70% of 77kWh = 54kWh, divided by your 9hrs of charging = 6kW per hour. Your Zappi is pushing out in the region of 7 and then you need to allow 10% approx. loss for AC>DC conversion. I'd say you are about 0.3-0.4hWh on the low side. Not a life-changing deficit in fairness, and that is on the basis that your charge is from 10% to 80%. If that was just an approximation and the actual charge acquired was say 8% to 83%, then that small difference would equate to 6.4kWh which puts you bang on IMO.

    Thanks. My question was mainly prompted by the people on here that use "Urban EV Units" rate between 2am and 5 am. For my car, that would not be nearly enough to get it from 10% to 80%.

    So either they have much smaller car batteries, or they charge it a little bit every night, or (i thought) maybe they are able to charge much faster than me.

    My understanding was that the optimal for EV battery life is to let it run fairly low (10-20%) and charge to 80%, so i try to manage that, and charge every second night. But maybe that is incorrect.

    Those that are on the 3hr cheap night rate ( or others, like myself, on the Energia 2-6am rate) typically charge a bit every night if they need the range. My daily commute is approx 80kms. I typically squeeze about 25kW into the battery over that period. Each kW gives me roughly 5-6kms, so the 4 hr charge will typically give me more than I need each day. Works out perfectly for my needs. Everybody is different though. And nobody is charging their car from very low to full charge in one session on either of these plans (bar small battery PHEV users) so don't sweat it. Little & frequent is the order of the day 👍

    It's the same meter regardless so I think that's why the standing charge is the same

    I feel like the Energia EV plan would work best in your case since you'd be doing a few longer range reviews of EVs so would need the 4 hour charging window

    My inverter charges the battery at 2.5kW so takes 4 hours. However the battery is set to not discharge below 20% so in reality it's never more than 3 hours

    I'm charging the battery every night and have 2 EVs. On the Flogas deal with 9 hours of night rate at around 12c/kWh, it's working out well so far, but I'm trying to compress everything down to the 2-4 hour window that most of the smart EV plans favour

    Energypal is great, but you need a few months of example usage to really get the best from it

    Thanks. My daily work commute is closer to 120 Km + other bits and pieces, and I generally get two days from one charge.

    A bit off topic, but does the number of charges make any difference to the battery life, i.e., is there any difference between charging from 30%-65% every night Vs 20%-80% every second night (in terms of impact on battery life)?

    I'm not with Electric Ireland but Flogas charge me more for being on a night rate plan, 9 hours, with a smart meter. If I switched to a smart plan with them, on the same meter, the standing charge would be a lot lower.

    I think they just make it up as they go along.

    There are different battery chemistries used by car manufacturers, both of which have their own advantages and disadvantages. My BYD utilizes Blade / Lithium Iron Phosphate (LFP) while another example, say the Audi Etron or a Hyundai Kona use Lith-Ion. Audi recommend that their battery is charged to MAX 80% when used primarily for shorter trips (probably the vast majority of users fall into this category) and increase to 100% when travelling long distances.

    By comparison, the FLP / Blade has no recommendation to avoid 100% charging, irrespective of your general usage pattern.

    Personally, I typically, keep my battery charged on the higher side (usually in the region of 80-90%) and would allow it to run down to circa 10% every few weeks. I would occasionally charge to 100% also, with no methodical focus whatsoever.

    In your case, I would wager that you are fine with your charging profiles, but I would be charging to MAX 100% occasionally, where the situation allows.

    How my charging behaviour affects the battery health, I have absolutely no idea. 8yrs/200,000kms warranty on battery & drivetrain alleviates any concerns that might otherwise exist.

    Is there any website that has up-to-date rates for provider's feed-in-tarrifs?



  • Registered Users, Registered Users 2 Posts: 2,570 ✭✭✭fafy


    I came across this a while back, so unclear if it is up to date:

    Huge differences up to almost 10 cent per unit, between suppliers, particularly important for bigger exporters/larger pv setups, but reductions are inevitably going to come, as consumption unit rates gradually decrease.

    The fuse in the meter cabinet would only be 80a if you upgraded to 16kva.



  • Registered Users, Registered Users 2 Posts: 66,721 ✭✭✭✭unkel


    Incorrect. If you upgrade from 12kVA to 16kVA, the fuse in the consumer unit will be upgraded from 63A to 80A and the fuse in your ESB meter box will be upgraded from 80A to 100A

    Hmm. I think it's 12kw? You're only supposed to run at 80% of the max fuse continuously? So 63×0.8x230v = 11.59kw?



  • Registered Users, Registered Users 2 Posts: 1,539 ✭✭✭foodaholic


    I hadn't heard from the retention team so I called to ensure that the credit on my account was refunded to me

    Asked if I was interested in staying but would only put me on a smart plan

    I'm D/N currently

    Told him no thanks



  • Registered Users, Registered Users 2 Posts: 1,513 ✭✭✭cannco253


    Energia told me the same thing, no new MCC02 plans going forward and that this was a company decision.

    I told them they never notified existing customers of this and they couldn't point me to anywhere on their website or bills where this is stated.

    Moved to Bord Gais MCC02 38% discount.



  • Registered Users, Registered Users 2 Posts: 5,628 ✭✭✭MojoMaker


    Quoting percentage discounts is somewhat meaningless without mentioning final unit rates. The implication is a bigger discount is better, when that may not be the case at all.

    MC02 24c/12c day/night with no contrived 'windows' seems to be a fair example for market value right now.

    This is what I gather are the best Smart D/N rates, kinda hard to find information on the Energia plans so they're potentially off slightly. I'm on an Urban plan.

    Despite lower rates from EI compared to my current rates, their lower FIT costs me around €150 for the year meaning I'm not actually saving much. I'd rather stick with Energia even with the 29% discount but if they're not giving people Smart D/N plans then I'm out of luck...

    No, your ESB fuse will be 80A if you have a 16kva connection. Page 19

    Max consumer protection size :80 amps

    That's the one in your consumer unit/between meter and consumer unit.

    The one in the DNO head is 100 amps

    On 16kVA

    I renewed with Energia on a D/N MCC02 a couple of weeks ago with the 38% offer.



  • Registered Users, Registered Users 2 Posts: 66,721 ✭✭✭✭unkel


    Have a look for yourself in any 12kVA and 16kVA installs and you will find the fuses are as I said they are :-)

    What rate is that on night and day rate please with the 38% reduction. Thanks



  • Registered Users, Registered Users 2 Posts: 1,828 ✭✭✭mailforkev




  • Registered Users, Registered Users 2 Posts: 127 ✭✭Bannerman1969


    Thanks. That's what I'm paying with Flogas up to March 2025. That's a very good rate especially for 9 hours overnight.



  • Registered Users, Registered Users 2 Posts: 1,828 ✭✭✭mailforkev


    Yeah, works out well for us. Have two EVs so the 9 hour window is useful. Mind you, I should really get solar and a battery, will do in the new year.

    This is correct, I have a 16kVA connection, the ESBN fuse is 100A and the consumer trip is 80A
