UK's First Community-Owned Solar Battery Surpasses Funding Target in Oxfordshire
A community-led initiative in Oxfordshire has raised over £640,000 to install the UK's first community-owned solar battery, exceeding its initial target ahead of schedule. The battery will store surplus clean energy and generate profits to fund local sustainability projects.

What's not represented
- · Local residents living immediately adjacent to the solar park and battery installation.
- · Traditional utility companies facing competition from decentralized, community-owned generation.
Why this matters
This milestone proves that local communities can successfully fund and own critical grid infrastructure, keeping energy profits within the local economy rather than passing them to large utility corporations. By solving the intermittency problem of renewable energy at a local level, the project offers a scalable blueprint for community-driven climate action.
Key points
- The Low Carbon Hub has raised over £640,000 from 270 investors to build the UK's first community-owned solar battery.
- The 12-megawatt-hour battery will be co-located at the Ray Valley Solar park in Oxfordshire.
- The system will store surplus midday solar power for use during the evening peak, saving 809 megawatt-hours of clean energy annually.
- Profits from the battery's operation will fund local sustainability initiatives, including energy efficiency upgrades for schools and homes.
The UK's first community-owned solar battery project has officially surpassed its initial funding target, raising over £640,000 from local investors nearly a month ahead of schedule.[1][5]
The initiative, spearheaded by the Oxfordshire-based social enterprise Low Carbon Hub, aims to install a 3-megawatt, 12-megawatt-hour lithium-ion battery at the Ray Valley Solar park near Bicester.[1][3]
Ray Valley Solar, which opened in 2022, is already one of the largest community-owned solar sites in the country, generating enough clean electricity to power approximately 7,000 homes.[4][6]
However, the site faces a common hurdle for renewable energy: intermittency. On particularly sunny days, the 19-megawatt solar farm produces more electricity than the local grid can immediately absorb, resulting in wasted clean energy.[2][6]

The new battery energy storage system (BESS) will capture this surplus power during peak daylight hours and store it until the evening, when household demand spikes and grid electricity is typically more carbon-intensive and expensive.[4][5]
Low Carbon Hub estimates that the battery will prevent roughly 809 megawatt-hours of clean electricity from being wasted each year—enough to power 300 homes annually.[1][4]
By displacing fossil-fuel generation during peak evening hours, the battery is projected to deliver an additional 102 tonnes of carbon savings every year, equivalent to taking 45 cars off the road.[4][5]
The total cost of the battery installation is £1.8 million. While the project initially sought £500,000 through a community share offer on the ethical investment platform Ethex, the overwhelming public response has pushed the campaign into an over-raising phase.[1][2]

More than 270 individuals and organizations have invested so far, with shares starting at £100.[1][5]

Dr. Barbara Hammond MBE, CEO of Low Carbon Hub, noted that every additional pound raised directly reduces the project's reliance on commercial loans, keeping a larger share of the financial returns within the community.[1][2]
The financial model is designed to be cyclical. Investors are targeted to receive up to a 5% return, while the broader profits from selling electricity back to the grid are channeled into local sustainability initiatives.[2][6]
Adding the battery is expected to increase the lifetime surplus available for community benefit by more than £1 million.[1][6]

These funds will support energy efficiency upgrades for local schools, homes, and businesses, effectively multiplying the project's environmental impact across Oxfordshire.[4][6]

Viewpoints in depth
Community Energy Advocates
Supporters who view local ownership as the key to a just energy transition.
Advocates for community energy argue that the transition to renewables must democratize wealth, not just decarbonize the grid. By owning the infrastructure, communities can capture the financial upside of energy generation—profits that would otherwise go to large utility companies. They point to the Low Carbon Hub's model, where energy sales fund local school retrofits and home insulation, as a blueprint for creating a self-sustaining cycle of local climate resilience.
Grid Operators & Planners
Professionals focused on the technical stability and efficiency of the national power grid.
From a grid management perspective, co-located battery storage is essential for managing the inherent intermittency of solar power. Grid operators welcome distributed storage projects like the Ray Valley battery because they alleviate local grid congestion during peak generation hours and provide dispatchable power during the evening peak. This flexibility reduces the need for expensive grid infrastructure upgrades and minimizes reliance on carbon-intensive 'peaker' gas plants.
What we don't know
- Exactly how much the final community share total will be when the funding window closes on June 26, 2026.
- How quickly the cost of utility-scale lithium-ion batteries will fall, which could impact the timeline for similar community projects across the UK.
Key terms
- Battery Energy Storage System (BESS)
- A technology that captures electricity from renewable sources and stores it in rechargeable batteries for later use.
- Megawatt-hour (MWh)
- A unit of energy representing one million watts of power sustained for one hour, commonly used to measure battery storage capacity.
- Intermittency
- The unpredictable nature of renewable energy sources, such as solar power only generating electricity when the sun is shining.
- Community Benefit Society
- A corporate structure in the UK where a business is run primarily for the benefit of the community at large, rather than just for its members or private shareholders.
- Co-located storage
- Installing battery storage at the exact same site as the renewable energy generation to maximize efficiency and reduce grid connection costs.
Frequently asked
Why does a solar farm need a battery?
Solar farms generate the most electricity during the middle of the day, which doesn't always align with when people use the most power. A battery stores the midday surplus so it can be used during the evening peak, preventing clean energy from being wasted.
Who owns the Ray Valley Solar battery?
The battery will be owned by the Low Carbon Hub, a community benefit society, on behalf of the hundreds of local individuals and organizations who invested in the community share offer.
What happens to the profits generated by the battery?
After paying a target return of up to 5% to investors, the remaining profits are used by the Low Carbon Hub to fund local sustainability projects, such as improving energy efficiency in Oxfordshire schools and homes.
How much did the battery cost?
The total cost of the battery installation is £1.8 million. It is being funded through a combination of community investments (currently over £640,000) and commercial loans.
