Latest developments

This webpage provides an overview of the proposal so members of the community can comment prior to the formal planning application being finalised and submitted. The pre- application consultation runs until <DATE>.

The proposed project is situated 200 metres to the North West of Junction 27 of the M5 motorway. It would be built on low grade agricultural land (ALC Grade 4). It is a significant energy infrastructure project that will modernise the local electricity grid to support the transition from gas and coal generated electricity to renewable energy from solar and wind. The project includes a series of ecological and landscape enhancement measures, such as the creation of a wetland habitat around the River Lyner to boost biodiversity.

You are invited to a public consultation event on the project
14.00-19.00 on <Date> at <Location>

OVERVIEW

Modernising local energy infrastructure

An energy super hub for Mid Devon

A 400MW battery energy storage project

Located on on land at Jersey Farm, next to Junction 27 of the M5 (EX16 7EJ)

Connected to National Grid overhead lines network

A local and national priority

Battery storage is key priority for responding to the climate emergency by maximising the use of clean, low cost energy from solar and wind farms across the UK

Local Community

The Junction 27 Energy Hub project will deliver meaningful benefits to the local community, including:

  • An annual electricity bill subsidy payment for those households closest to the site
  • An annual financial contribution to support a local charity to implement energy saving measures for those on low incomes
  • An estimated £1m per year in business rates for reinvestment in local initiatives
  • A community development fund to support energy efficiency and renewable energy projects in the community
Delivering for Mid-Devon and
Devon

The Devon Carbon plan outlines the role of energy storage in Devon’s strategy for reducing carbon emissions across the county to net zero –

”Deploying flexibility services and storage technologies will reduce the amount of new renewable energy capacity required. This will make best use of the resource, reduce investment costs and avoid the need for fossil-fuel powered peaking plants to generate power when demand outstrips the instantaneous supply from renewables.”

Improving natural ecosystems

It is estimated that Britain has lost around 50% of its biodiversity since the 1970s due to intensive farming, new housing and commercial development.

8 hectares of land has been set aside at the site for ecological enhancements including wetland habitats and wildflower meadows.

We estimate the scheme would deliver a biodiversity net gain of more than 20% across the site, bolstering nature’s ability to provide food and recycle nutrients, purify water and air, and slow down climate change by removing carbon dioxide from the atmosphere.

Enabling the transition to clean, low-cost and secure renewable energy

The cost of not having battery storage in the UK is high

Financial Times

Uk warned of risk to key net zero goal without power grid plan

“In a sign of grid infrastructure struggling to keep pace with changes to the power system, the watchdog found that generators were being paid up to £62 million per day to cut output when supply outstripped demand and could not be stored”

The Guardian

“National Grid pays high price for gas-generated power during UK cold snap”

In total, the cost of balancing the system on Tuesday this week was estimated at between £5m and £10m …. The cold, still weather reduced wind power and pushed up demand this week, while strikes at EDF’s nuclear plants in France also put a strain on the grid.

Batteries solve one of the biggest challenges facing renewable energy. Matching weather dependent solar and wind electricity with household and business electricity demand.

Vital statistics
  • 8 hectares for batteries and new substation
  • 8 hectares for nature restoration project
  • 104 battery energy storage units (2.6m high, 4.87m wide, 13m long)
  • Capable of powering all the homes in Mid-Devon for 10 hours when fully charged
  • Substation maximum height 12.5m
  • 40 year operational lifetime
  • 12-15 month construction timeline
The right location

Strategically positioned on the National Grid transmission network to be able to support electricity supply across Devon and maximise the local use of renewable energy from local solar farms and offshore wind farms.
Built in an area that already hosts major road, rail and electricity network infrastructure. Proximity to motorway network will reduce construction traffic passing through local towns and villages.

Neighbourhood visibility

The site already benefits from significant tree and hedgerow screening along the A361 boundary. There is some existing hedgerow along the lane to Ayshford to the North of the site. Both boundaries will be supplemented with further planting to close any gaps and screen the site from both roads.

Frequently asked questions

We answer common questions and concerns that communities may have

Any noise from a battery energy storage site comes from the fans that cool the batteries and the inverters that transform the DC electrical current from the batteries to AC power for transmission on the grid. They are usually not audible above ambient noise, particularly when sited around busy roads as is the case here. A full noise assessment will be conducted as part of our planning application and factored into the final site design to ensure that it cannot be heard by any neighbouring households.

Who we are

Clearstone Energy is a leading independent developer of renewable energy and energy storage projects that increase the availability of clean energy and improve the resilience of the electricity grid.

We are working with National Grid to develop a portfolio of strategically located solar generation and battery storage projects that will help build a UK energy system based on clean, low cost and renewable energy.

Our experienced team has a track record of developing successful renewable energy projects that are providing clean and reliable energy to communities across the UK.

Since founding in 2016, Clearstone Energy has developed nine energy projects in the UK. Two are operational and seven are in construction.

Next steps

Once the public consultation closes on <DATE> we will integrate your feedback into a final project plan and submit a formal planning application for the project to Mid Devon County Council. As local residents you will be asked for your comments, support or objections to the project as part of the planning application review process. Those living closest to the site will typically be contacted by letter by the Council when the planning application has been received.

We also send details of the planning application by email to those residents that we have email addresses for. If you would like us to do that for you please submit your email address here.

    Solar Energy

    The UK’s energy markets have experienced turmoil and rising electricity costs since 2021, leading to a surge in rooftop and ground-mounted solar installations in 2022. Two-thirds of UK solar generation comes from large-scale projects, and solar energy is the fastest growing and lowest cost renewable energy technology.

    More about Solar

    Battery Storage

    Battery energy storage is key for reliable renewable energy. Large scale batteries near wind and solar sites ensure a constant electricity supply. Transitioning from gas to batteries will make energy cleaner, more secure and cheaper. In 2022, UK wind farms were paid £62m a day to not produce power because of the lack of storage, which cost consumers.
