Octopus Energy explores new home battery systems in deal with manufacturer Ampace
A new partnership aims to develop affordable, next-generation home battery storage that could help households manage energy use and reduce their bills.

Key points
- Octopus Energy has signed an agreement with battery firm Ampace to collaborate on smart home energy storage technology.
- The partnership aims to create more affordable and efficient batteries to help households store energy and manage their usage.
- The collaboration will initially focus on opportunities within European markets where Octopus currently operates its retail energy business.
Octopus Energy has announced a memorandum of understanding with the lithium-ion battery technology company Ampace to explore the development of advanced home energy storage systems. The companies intend to combine Ampace's hardware expertise with the software and energy management services provided by Octopus.
The collaboration seeks to produce greener and more affordable storage units for households. This move is part of a broader push by Octopus to expand its range of green home technology, which already includes heat pumps and electric vehicle chargers.
How the technology could help
Home battery systems allow households to store electricity when costs are low and use it later when prices increase. By managing energy use more intelligently, these systems aim to lower household bills and reduce the strain on the national power grid during times of high demand.
The companies are looking at advanced battery chemistries, including sodium-ion technology and designs with longer lifespans. Octopus states that the partnership will focus on hardware and software working together to help customers cut energy costs.

Future plans for Octopus storage
Separate from this new collaboration, Octopus has previously announced plans to launch a home battery range called Octopus Nook. These units are expected to be available as a 2kWh plug-in system or as wall-mounted systems with 5kWh or 10kWh capacities.
The Nook systems will be stackable to suit different household needs. While details regarding the specific cell technology for these initial units have not yet been released, the company continues to grow its portfolio of connected home energy solutions.
What it means for you
- There are no immediate changes for households, as the partnership is currently in the initial exploratory phase.
- The development of new battery options aims to help households store low-cost energy for use during peak hours.
- Octopus plans to launch the 'Nook' battery range, which will offer various storage capacities for different home sizes.
