The Independent reported Tuesday that Octopus Energy has reached a deal with Contemporary Amperex Technology Co., Limited (CATL) and Ampace to develop household storage products, while Octopus plans a separate 2027 rollout of its own Nook batteries.
The Independent said the partners aim to make home storage systems less expensive and extend their useful lives. Greg Jackson, CEO of Octopus Energy Group, told the outlet that the project would pair battery equipment with energy-management software to reduce household electricity bills. Jackson said the partnership “will transform home energy storage.”
A home battery can store electricity bought when prices are low or generated by solar panels, then supply a household when grid power costs more, according to The Independent. The outlet said wider use could ease pressure on the grid during peak demand. It also reported that systems able to send stored power back to the grid could offer another way to reduce household bills.
TDK says Ampace is a joint venture between CATL and Amperex Technology Limited. Raymond Ye, Ampace’s president of residential energy storage systems, told The Independent that Europe’s energy transition is increasing demand for flexible home energy options. He said the partnership could accelerate innovation and deliver more value to the market.
Octopus and CATL separately announced a European battery-swapping venture for electric trucks on June 22. That project is distinct from the home-storage collaboration described in The Independent’s report.
Octopus’s Nook range is also a separate plan. The company says it aims to offer the products in the United Kingdom, Germany, France, Italy and Spain in 2027. Its announcement describes the Octopus Nook Cube as a 2-kilowatt-hour unit that customers can expand to 10.5 kWh, while the wall-mounted Octopus Nook Colossus is planned in 5 kWh and 10 kWh models.
