Octopus Energy has introduced Nook, a new range of residential battery storage systems designed to expand access to home energy storage, including for apartment dwellers and renters.

The lineup includes the Octopus Nook Cube, a 2 kWh plug-in battery that connects to a standard household socket and can be expanded to 10.5 kWh by adding additional units. The company also unveiled the Octopus Nook Colossus, a wall-mounted 5 kWh battery that can be scaled to 30 kWh for larger homes.

Both systems are compatible with rooftop solar installations, come with a 12-year warranty, and are designed to store electricity when prices are low for use during higher-priced periods.

Octopus said the Nook range will launch in the United Kingdom in 2027 before expanding to Germany, France, Italy, and Spain.

The company also announced Swaptopus, a joint venture with CATL to develop a European battery-swapping network for electric trucks. The first battery-swapping hubs are scheduled to open in the United Kingdom in 2027. An Octopus spokesperson told ESS News that the company aims to expand the network across Europe, including Italy, by 2035.

Octopus entered the Italian retail energy market in 2022 and says it now serves more than 900,000 customer accounts in the country. It has invested more than €250 million ($285.9 million) in Italy to date and plans to increase that figure to more than €1 billion by 2030.
