Excess Wind Energy

YFlyer · 30-01-2020 1:46am #1

On Eco Eye Eirgrid said that at night time if there is any excess wind energy. They can use smart meters such as Climote to pump the electricity into hot water tanks during this period.

Anyone know will this electricity be cheaper than the regular night time unit rate?

It is likely that in future we will have a much more variable electricity rate than just the day rate and night rate we have now. It makes sense to sell excess electricity ,that we have no use for, cheaply. So people can use it for heating, charging up EVs and other batteries, etc. And to make peak demand electricity very expensive.

I'd say it's quite possible that the cheapest rate will be around 1c / kWh and the most expensive rate around €1 / kWh within the next 5 years or so

They mentioned the potential of having these meters in up to million hot water tanks.

Denmark currently use EVs for storing and distributing electricity around the grid?

Could be an expensive cup of coffee in the afternoon.

The wholesale price of electricity in the balancing market falls below zero now and again.

You still have to pay distribution and transmission on this.

I have a little box that turns on a relay when wind is high and demand is low.

On Eirgrid the System Demand has just shot up to 4,000 MW. Don't think that ever happen at this early in the morning before.

Currently wind is providing well over 50% of all electricity in Ireland. Which is pretty good going for afternoon time on a working day. We need this to be 100% on a windy day within the next few years though.

Think it was over 60 at one stage last week. Been a good couple of weeks for charging off renewables.

What I can't understand is that wind energy generated is mitigated during the night. Weather forecast is strong
