Are Grid Services new?
Grid Services already exist in industrial and commercial energy markets where National Grid and the District Network Operators pay for grid balancing services to minimise risk of blackouts in times of supply and demand mismatch. Owners of large batteries can also be paid to soak up excess generation or release when top up levels are required.
It would be difficult for a single domestic battery to operate in the same way, which is why we’re building a network of small-scale batteries. When aggregated together, they can be used like large scale storage to help manage the peaks and troughs of energy production and demand. This supports the growth of renewables and an increase in number of small scale generators on the grid.
The way in which we use energy in our daily lives will change as we move to a Net Zero society. The growth of EVs, for example, will put different demands on the network so we need a more flexible, dynamic system to deal with the transition.
How will Grid Services work with my individual battery?
The Powervault 3 home batteries will all operate as a group, not individually, so your battery will not be responding to peaks and troughs of the grid by itself. The smart controls within the Powervault 3s can be synchronised by Powervault’s SmartStorTM software platform, and respond to signals from EDF’s PowerShift optimisation system when Grid Services are required. As an example, you may see a time during the night when the battery does a series of small charges and discharges, or an additional charge being fed to the battery during the night if there was excess wind energy available on the grid, but there is not enough demand on the network to make use of it. Alternatively, during the peak demand hours of early evening the battery would be used to power your house completely, removing your consumption from the grid, thereby reducing demand. At all times the health of the battery is monitored and you have full visibility of your amount solar generation, grid charging, and discharging in the Powervault Portal.
Your EDF Grid Services contract is for ten years. We pay an annual amount in return for occasional access to the battery. You can leave the Grid Services contract at any time. You can read the full Ts&Cs.
