Clearstone Energy has secured a grid connection at Tiverton for a battery energy storage project. We are in the process of sharing our proposal with the local community for their input.  

The South West of England generates more solar energy than any other region of the UK. It is also the furthest point on the transmission network away from off-shore wind farms in the north of England and Scotland. The Junction 27 Energy Hub project will provide much needed storage capacity to help balance electricity supply and demand across Devon and Cornwall.


Biodiversity benefits

It is estimated that Britain has lost around 50% of its natural biodiversity since the 1970s due to intensive farming, new housing and commercial development. We design all of our sites to help build back natural biodiversity. 

More than half of the project site for the Junction 27 energy hub project has been set aside for initiatives that will enhance nature and wildlife. Proposed enhancements include:

  • The creation of wetland habitats and/or water meadows adjacent to a nearby river 
  • Planting of new hedgerows and reinforcement of existing ones.
  • The creation of bird and animal habitats across the site.
  • Grazing meadow in the fields between the batteries and the river.

These initiatives will support significant increases in biodiversity on the site.

Community benefits

We want our projects to be a catalyst for the broader adoption of renewable energy and energy efficiency projects within the communities that host them. 

The Junction 27 Energy Hub will offer financial support annually to enable low income households in the community to implement energy efficiency initiatives that would permanently reduce energy bills. Those residents that live closest to the site would receive an electricity bill subsidy payment every year the project is operational so they benefit directly from the energy produced by the project. We would also make funds and support available for community energy projects, such as installing solar panels on community buildings.
