Low Carbon Hub
Low Carbon Hub (formally The Low Carbon Hub IPS Limited) is a community benefit society and social enterprise based in Oxford, England. Founded in 2011, it develops and manages community-owned renewable energy installations across Oxfordshire, and uses the surpluses generated to fund energy efficiency programmes, community grants, and innovation in local energy systems. It is registered with the Financial Conduct Authority under the Co-operative and Community Benefit Societies Act 2014, registration number 31903R.
Background and founding
Low Carbon Hub was established in 2011 as a spin-out from West Oxford Community Renewables, with support from Oxford City Council. It was originally set up as two parallel legal entities: an Industrial Provident Society (IPS) to hold its energy assets and raise community investment, and a Community interest company (CIC) partly owned by its network of local low-carbon community groups. In 2023, the two-entity structure was consolidated, with all activity moving into the IPS.
Its stated aim is to accelerate the transition to a fair, zero-carbon energy system, with a particular focus on the role of communities and households at the "grid edge" — the local distribution network where most energy is consumed.
The organisation is led by CEO Dr Barbara Hammond MBE.
Legal structure and governance
Low Carbon Hub is a registered society under the Co-operative and Community Benefit Societies Act 2014. Members are investor shareholders who hold withdrawable share capital — a form of community share that cannot be traded on a stock market or transferred between individuals, but can be withdrawn subject to board approval. Membership operates on a one member, one vote principle.
Two of its largest energy projects are held in wholly owned subsidiaries:
- Low Carbon Hub Sandford Hydro Ltd (Company registration number: 9743887)
- Ray Valley Solar Ltd (Company registration number: 12279415)
All surpluses are reinvested in community benefit activity, including grants to community groups and funding for energy programmes.
Renewable energy portfolio
As of 2025, Low Carbon Hub manages 24.3 MW of installed renewable energy capacity across Oxfordshire, comprising 56 installations. Its portfolio generates approximately 24.19 GWh of clean electricity annually and is estimated to save around 5,456 tonnes of CO₂ per year.
Rooftop solar
Low Carbon Hub's rooftop solar programme began in 2013 with installations in Eynsham, developed in partnership with local community group GreenTEA. The programme expanded significantly from 2014 to 2016 through the OxFutures project, a European Regional Development Fund initiative delivered in partnership with Oxford City Council and Oxfordshire County Council, which funded solar installations on schools and businesses across the county.
By 2019, Low Carbon Hub had installed solar panels on more than 30 Oxfordshire schools. Rooftop capacity stood at 4.3 MW as of 2024, with plans to expand to 7.3 MW.
Sandford Hydro
In 2016, Low Carbon Hub raised community investment to fund Sandford Hydro, a run-of-river hydroelectric scheme on the River Thames at Sandford-on-Thames, near Oxford. The scheme was fully commissioned in 2017. With an installed capacity of 440 kWp, it is described as the largest community-owned hydroelectric scheme on the Thames.
Ray Valley Solar
Ray Valley Solar is a ground-mounted solar park located at Arncott, approximately three miles south-east of Bicester in North Oxfordshire. It is one of the largest community-owned solar parks in the United Kingdom.
Construction began in May 2021, and the park was connected to the national electricity grid in July 2022. It generates 19.5 GWh of clean electricity annually — enough to power approximately 7,000 homes — and saves an estimated 4,000 tonnes of CO₂ per year. The project is projected to generate £13 million in community benefit funding over its lifetime.
Funding came from multiple sources, including a community share raise that reached its £3 million target in March 2021, a loan from Triodos Bank, and a long-term loan of approximately £4.1 million from Oxford City Council. The project was also supported by grant funding from Innovate UK's Prospering from the Energy Revolution programme, as the park served as a trial site for Project LEO.
The site is managed as working land, with solar generation alongside sheep grazing and active biodiversity measures, including 3.7 km of new native hedgerows, pond management to support great crested newts, wildflower grassland, and a beehive operation.
Battery storage
In 2026, Low Carbon Hub announced plans to add a 12 MWh battery energy storage system to Ray Valley Solar. Described as the UK's first community-owned co-located battery energy storage system, the installation is intended to store surplus solar generation during peak daylight hours and discharge it during periods of higher demand.
Project LEO (Local Energy Oxfordshire)
From 2019 to 2024, Low Carbon Hub was a core partner in Project LEO (Local Energy Oxfordshire), a multi-partner energy innovation trial funded by Innovate UK's Prospering from the Energy Revolution programme. The project, led by Scottish and Southern Electricity Networks (SSEN), was described by UK Research and Innovation (UKRI) as one of the UK's most ambitious, wide-ranging and innovative energy trials. It investigated how smart local energy systems — integrating community generation, storage, demand flexibility, and local power purchase agreements — could reduce pressure on electricity network infrastructure and accelerate the transition to net zero.
Ray Valley Solar served as a key generation trial site within the project. Outputs included replicable business models for community energy projects and findings on how local generation assets can support grid balancing.
LEO-N
Following Project LEO, Low Carbon Hub participated in LEO-N (Local Energy Oxfordshire – Neighbourhoods), a development project exploring smart energy systems at neighbourhood scale.
CAPZero
CAPZero (Community Action Plan for Zero-Carbon Energy) is Low Carbon Hub's community-led net zero planning programme, described as the first community energy action plan of its kind in the UK. The programme covers eight parishes in West Oxfordshire — including Eynsham, Cassington, Freeland, Hanborough, and Stanton Harcourt — and models how a cluster of communities can develop a zero-carbon local energy system. A CAPZero report was published in 2024.
Energy Solutions Oxfordshire
Energy Solutions Oxfordshire (ESOx) is a programme providing free energy assessments and decarbonisation planning support to businesses in Oxfordshire, delivered in partnership with local authorities including Cherwell District Council.
Community grants
Low Carbon Hub operates a Community Grants Fund for its network of affiliated local low-carbon community groups across Oxfordshire. Grants are available in two tiers: small grants of up to £500 and larger competitive grants of up to £5,000. Projects funded have included electric cargo bike hire schemes, thermal imaging campaigns, home energy efficiency measures, and sustainable transport initiatives.
Investment
Low Carbon Hub raises capital for its energy projects through community share offers, in which members of the public can invest from £100. As of 2025, the organisation had approximately 1,906 investor members. Anticipated lifetime interest payments to investors are projected at £2.4 million. The organisation distributes approximately £2 million per year in community benefit funding.
Recognition
Low Carbon Hub has received an Ashden Award, whose judges described it as having "an extremely compelling vision for the rivers and rooftops of Oxfordshire to be the power stations of the future, delivering economic, social and environmental benefits for residents."
CEO Dr Barbara Hammond was appointed MBE.
