@chandykris Exactly the same here. We now have 13.5kWh of storage and expect to be doing 2.5-3 cycles per day in the coldest depths of winter. In the milder weather I doubt we will be cycling the battery so hard, but will be topping up 3 times per day from the grid. I'm not overly concerned about the battery - it has an unlimited cycle warranty, it will only really be cycled hard for 8-12 weeks per year and we bought it to be used, not to hang on the wall looking pretty. Plus the more it's cycled, the quicker it pays for itself.

Samsung 12kW gen6 ASHP with 50L volumiser and all new large radiators. 7.2kWp solar (south facing), Tesla PW3 (13.5kW)
Solar generation completely offsets ASHP usage annually. We no longer burn ~1600L of kerosene annually.

My attention was also drawn to the possible introduction of aggregators - possibly our energy suppliers?

Aggregators have been recognised for many years, and it's a different concept to Energy Suppliers, who buy on the wholesale market.

In it's most simple interpretation, and aggregator is geographically constrained and is acting as a Community Energy 'company'.

It might buy electricity solely from its members (shareholders) and sell only to them.
Or it might also have its own generation and storage assets.

The aggregator pays the DNO for Distribution Use of Service (DUoS) charges,
but can also earn income from them for operating within a 'Demand Flexibility' contract.

 

For Forum Members in the Midlands, NGED is hosting a Community Energy seminar/workshop day on Thurs 18th Sept at Birmingham.

The event is organised by the Exeter-based Regen group, who invite you to register online here.

NGED provide refreshments, including a buffet lunch.
They will also have relevant staff present, such as Network Planners and Community Energy engineers (yes, they exist within NGED!)

Separately there will be staff from agencies who can help new Community Energy groups to access grant funding for feasibility studies etc.

 

Note that the day is centred on Community Energy, and does not address:

  • national energy policy
  • tariff and billing issues
  • generation assets being installed by 3rd-parties (commercial solar farms)

 

Save energy... recycle electrons!
