Irish Smart Meters are not Smart Enough

Smart meter electricity plans in Ireland do not take into account how plentiful the wind and sunshine is. You have one time based rate that does not change even if there is a glut of renewable electricity.


If the price dropped like the wholesale price does. It would incentivise people to take up energy when it is cheap. This would reduce peak demand later.
 

A large percentage of people now have electric cars. 20% of new car sales are electric. Filling them when wholesale prices are low reduces demand later. But at the moment there is no connection between wholesale and retail prices.

Even without batteries these times could be used to heat water for showers in the morning Energy Cloud is a charity that encourages this 'Diverting surplus renewable energy which would otherwise be wasted, with a primary focus homes in fuel poverty'. The price mechanism will do it as well. If electricity becomes cheap because it is plentiful people will use more of it then.

'The price of lithium-ion battery packs has dropped 14% to a record low of $139/kWh' and that was 2023 and prices keep dropping. At 44 cents a kWh, the current rate, 285 charges for free would pay for that battery. We are getting to the point where a battery charged at night by wind and during peak sunshine, when there are low wholesale prices, can be used in the morning and in the evening, twice a day. Which means with lower cost electricity than 22c that is currently paid at night in smart schemes batteries pay for themselves really fast.

Large infrastructure projects are now being rejected because of our electricity grid not being stable enough. South Dublin Council refuses Google Ireland data centre planning permission. And one simple way to reduce this is allowing smart meters to actually be smart and reduce retail prices when wholesale prices drop. That incentivises electricity usage to be match supply.
