Ray Valley Solar, one of the UK's largest community-owned solar parks, is located in Arncott, Oxfordshire, nestled among hedgerows between a motorway and the River Ray. The site, which is difficult to spot from surrounding country lanes, hosts nearly 36,000 solar panels and generates enough clean electricity to power approximately 7,000 homes annually.
Community Benefits and Future Plans
The solar park's profits are reinvested into local community initiatives aimed at reducing carbon emissions and improving energy efficiency in homes, schools, and businesses across Oxfordshire. Now, the Low Carbon Hub, the community energy organization behind the project, is seeking crowdfunding to install battery storage on site. This would be the first community-owned battery at a renewable energy project in the UK.
On very sunny days, the solar park produces more electricity than the local grid can handle, leading to energy waste. The battery will capture surplus solar power during the day and release it during evening peak demand, when the grid is more carbon-intensive and electricity prices are higher. This will allow the park to generate more revenue, which will be reinvested into local sustainability projects.
Battery Specifications and Funding
The battery will have a capacity of 12 megawatt hours, enough to power an additional 300 homes annually. By selling stored electricity at higher evening prices, the Low Carbon Hub estimates it can increase its community benefit contribution to £1 million over the battery's 15-year lifespan. The hub is seeking to raise between £500,000 and £1.3 million through its Community Energy Fund on the investing platform Ethex, with shares available from £100 to £100,000. Investors are forecast to receive up to 5% return on their investment.
Barbara Hammond, CEO of the Low Carbon Hub, expressed confidence in the fundraising effort, recalling the successful £3 million raise for the solar park itself. Despite the global energy crisis and cost-of-living concerns, early interest in the battery investment has been strong.
Investor Perspectives
Dale Hoyland, a 41-year-old team leader in climate action services at Oxfordshire County Council, invested in Ray Valley Solar and is supporting the battery installation. He emphasized that the community ownership model empowers individuals to contribute to climate action, even with modest sums. Eleanor Watts, an investor in her 70s and active in a local environmental group, has seen her group receive grants from the hub for solar panel installations and energy-saving workshops. She values the opportunity to combat the climate emergency through her investment.
The project has attracted interest from other community energy groups across the UK. Hammond advises seeking expert technical consultants. The Low Carbon Hub operates 56 community-owned renewable energy projects in Oxfordshire, including rooftop solar and hydroelectric plants, and supports 50 community groups in carbon-cutting initiatives.
Government Support and Policy Needs
The UK government has pledged up to £1 billion for community-owned green energy schemes to address resistance to renewable projects and ensure local benefits. However, Hammond noted that more policy action is needed to ensure inclusive access to clean energy benefits.
