Dartford Energy Hub | Public Consultation
Clearstone Energy is proposing to develop the Dartford Energy Hub – a 300MW battery energy storage facility – on land off Station Road, Southfleet, Dartford. This webpage provides an overview of the proposal so local residents can comment prior to the formal planning application being finalised and submitted.
The Dartford Energy Hub would store excess electricity available when generation from the UK’s wind turbines and solar farms is higher than demand and release that energy back onto the grid when demand is higher than generation. This network balancing function is critical to ensuring a reliable electricity supply for local homes and businesses and currently fulfilled by gas-fired power stations.
The project would connect to National Grid’s Northfleet Substation. As the grid supply point for homes and business across Dartford, Gravesham and Sevenoaks Boroughs, Northfleet Substation is a strategically important location for adding battery energy storage to the electricity grid. The project includes a comprehensive package of community benefits to ensure that the local community benefits directly from this local renewable energy project.
Capable of storing energy equivalent to 1 hour of power for all homes in Dartford, Gravesham and Sevenoaks Boroughs when fully charged
Dartford Energy Hub Impact
Would displace 40,000 tonnes of CO2 emissions from gas fired power plants each year
Equivalent to planting 1.9 million trees

THE CRITICAL ROLE OF BATTERY ENERGY STORAGE
Built for an era of coal and gas fired power stations, the existing UK electricity network needs upgrading to support the deployment of renewable, low carbon energy. The inflexibility of the network is adding costs to bills and failing to deliver the emissions reductions needed to prevent climate change.
Batteries solve one of the biggest challenges facing renewable energy. Matching weather dependent solar and wind electricity with household and business electricity demand.
Currently, gas power plants are turned on to supplement wind and solar energy supply and meet peak electricity demand between 7 and 9am and 6 and 8pm
Batteries maximise the amount of renewable energy we can use at home and reduce the number of times we need to turn on a gas fired power plant to meet peak demand, saving money and reducing GHG emissions
Weather dependent wind and solar energy farms often produce more energy than is needed to meet electricity demand overnight and at off peak times during the day
With both supply and demand fluctuating across the day, batteries store energy when there’s more than needed to meet demand and discharge it when there’s less than needed
Example Battery Storage Facility
The total site area for the project is fixed at 11 hectares with the battery facility accounting for 5.5 hectares. The site is located next to existing commercial development. Connection to the electricity grid would be via underground cable to Northfleet Substation on the north of the A2. The cable route would follow the path of a disused railway line to avoid disruption to local roads. The plan below shows an example of what the final scheme could look like. With the feedback gained from this public consultation we will work up a final design for submission to Dartford Borough Council as part of our planning application for the project.

Frequently asked questions
No – while the facility would generate some low-level electrical noise from the inverters, switchgear, and fan equipment this noise would not be perceptible beyond the site boundaries. To demonstrate this, a Noise Impact Assessment will be submitted as part of any future planning application.
All Clearstone projects must comply with the standards set out in our comprehensive Battery Safety Standards Plan. Our safety plan draws on best practice from the UK’s National Fire Chiefs Council (NFCC) and the US’s National Fire Protection Agency (NFPA). These standards cover all aspects of the project – technology, site design, installation, operation and emergency response plan – to ensure that it meets the highest safety levels. Kent Fire & Rescue Service will be consulted on the project at all stages of its development and operations.
No, this would be a temporary 40-year use of the land, with batteries, other equipment and hard infrastructure removed at the end of the project and the land returned to agricultural use.
The land is privately owned, Clearstone Energy has an agreement in place with the landowner for the use of the land. We will be applying for planning permission for the development area outlined on this web page and have no plans to develop the remainder of the field with agricultural use continuing.
No. Most of the components are prefabricated offsite rather than assembled in situ. On site construction would be restricted to the laying of access tracks and creation of level platforms for the battery containers to sit on. Prefabricated units would be craned into position ready for cabling and connection works. As such, project construction would take 6-9 months.
The lithium-ion batteries that will be used in the project are not reliant
on scarce raw materials. There are established recycling processes for recovering the most common elements used in battery construction – iron, phosphate and lithium – for re-use.
Typically, there would be two to three HGVs a day bringing prefabricated units to the site during construction. Construction traffic would route directly from the A2 and Station Road to the site avoiding residential areas. Once operational, traffic would reduce to a light goods van visiting a couple of times a month.
No, there will be no lighting on site.
The maximum height of the batteries would be 3m. However, these would be screened by existing hedgerows and new woodland and hedgerow planting.
Clearstone Energy is working with an experienced team of landscape and ecology consultants who are currently finalising planting recommendations. Anything we plant will be native to the local area. We will also be responsible for maintaining planting across the lifetime of the project. This commitment would be part of any planning approval for the project.
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 solar generation and battery storage projects that are building 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 eleven energy projects in the UK. Two are operational and nine are in or awaiting construction.
We believe that our projects can do more than energy generation and storage. They support the adoption of renewable energy and energy efficiency technologies in the communities that host them. They provide opportunities to build habitats for wildlife and contribute to the preservation of local ecosystems. They provide support for community projects.

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.
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.
