E.ON Invests £4 million In Allume Energy To Boost Solar Rollout For Flats
The title of this post, is the same as that of this article on Solar Power Portal.
These three paragraphs explain the deal and say a small amount about Alume’s SolShare system.
Energy supplier E.ON UK has today (17 June) announced that it has signed a strategic investment agreement with Australian firm Allume Energy to help the firm expand into the UK.
E.ON UK has invested £4 million into Allume Energy to enable Allume to expand the reach of its SolShare technology within the UK market. SolShare allows solar energy from a single rooftop solar PV installation to be fairly shared amongst multiple homes in the same building in order to allow residents of flats to access solar PV energy.
Residents are supplied their energy when they are using by a pre-determined allocation, allowing them to lower their energy bills. Many blocks of flats that do have solar panels fitted currently only use this energy to power the common areas of the building while residents still pay their full electricity bill. According to Allume, a shared rooftop solar PV system can reduce resident energy bills by between 30% and 60%.
I must say, that when I read this article, it had something of the too-good-to-be-true about it.
But.
- My solar installation on a fair-sized roof cost me about £6,000 and I am constantly surprised at how much electricity it provides.
- If you have fifty flats, they all won’t do their weekly washing at the same time each week.
- I wouldn’t be surprised to see a big battery somewhere or a small battery in each flat.
- The batteries could soak up any excess electricity or charge on cheap-rate overnight electricity.
- Do Allume’s engineers go through every flat and make suggestions about saving energy?
- Is the pattern of electricity usage in a block of flats predictable from past usage and factors like weather, the time of the year and what’s on television?
- I wouldn’t be surprised that Allume have performed extensive mathematical modelling on blocks of flats.
I think this deal could be a winner foe E.ON, Allume and their customers.
I have some ideas about the use of the system.
Would It Work On A Small Housing Estate?
A small housing estate would be a number of solar roofs feeding a number of houses, whereas with flats it will be one roof feeding a number of dwellings.
I suspect that with a well-designed sharing and pooling system, a lot of features of the flat-powering system could be used to power houses.
How Does The System Handle Electric Vehicles?
The system could use these to store electricity, so that they are always charged at the cheapest rate.
And when there is a shortage of electricity, the electricity could be borrowed by the Allume system.
Conclusion
If you have community sharing their own source of electricity, you can probably make ideas work, that wouldn’t in a single application.
My nose says Allume’s idea has legs.
