We can feed back the excess we produce into the system. And on windless days the EBS provides us with the electricity we need at € 0.1324 per kWh.
But... We give our surplus for free! There is no tariff in Ireland to sell electricity to the ESB. The likes of Scotland pay 11-12cent per kWh.
Is the grid not over loaded?
Wouldn’t micro energy generation help the problem?
