In the UK, domestic energy company Eaton has agreed a partnership with football club Manchester City to market its home energy storage unit. The aim is to encourage fans of the football club to consider investing in a home energy storage kit, which uses second-life batteries from Nissan's electric vehicles.
When connected to the residential power supply or a domestic renewable energy source, such as a solar PV installation, the unit stores available energy, and release it when demand and costs are high. This enables homes to avoid expensive daytime or peak tariffs.
Domestic energy storage systems can both save money on energy tariffs, and enable people to make additional revenue by selling their stored energy back to the grid.
The move to market energy storage systems to football fans is clever: high tariffs are linked to large-scale behaviours, such turning on the TV or making food at times dictated by games.
Will we see networks of energy-savvy fans harness domestic energy generation, storage and peer-to-peer trading mechanisms to develop their own power grids?
