The price of electricity in germany is almost twice what it is here, but still that isn't the important part.
The senior vice president of technology and innovation at E.ON, Susana Quintana-Plaza, commented: “E.ON is committed to empowering customers and promoting decentralized energy solutions while expanding our power grids and making them smarter.”
That is the important part and an extremely dangerous omission in the forward thinking of UK systems and grid.
We pay for an averaged tariff and are excluded from high cost energy, the Germans are going to open this up to a whole rake of decentralised products and solutions.
In the UK consumers are excluded from high returns on energy ( up to £2500 mWh wholesale) and technologies such as the above could be extremely viable practically anywhere.
The instant on grid load balancing they could provide at each branch of local substation could massively reduce the overall cost of electricity.
This could also massively increase grid resilience and renewable adoption capacity levels.
This is a hugely profitable area for anybody but the consumer.
