About the developer
Statkraft is at the heart of the UK’s energy transition. Since 2006, Statkraft has gone from strength to strength in the UK, building experience across wind, solar, hydro, storage, grid stability, EV charging, green hydrogen and a thriving markets business.
Statkraft is a global company in energy market operations, more than 7,000 employees in over 20 countries.
We’ve invested over £1.4 billion in the UK's renewable energy infrastructure and facilitated over 4.3 GW of new-build renewable energy generation through Power Purchase Agreements (PPAs).
Across our UK businesses we employ nearly 500 staff in England, Scotland and Wales and play a key role in helping the global business reach its goal of 9 GW of developed wind and solar power by 2025.

About the project
Statkraft’s Greener Grid Parks are designed to enable the electricity grid to be more flexible and to solve stability in your area. In 2020, Statkraft was appointed by National Grid to help them achieve their ambitions to operate a zero carbon grid by 2025. We won a further contract in 2022 to continue this work with projects at Coylton and Neilston in the West of Scotland.
The future is in renewable energy generation, however our national grid infrastructure is still geared toward outdated fossil fuel technologies. Without much needed upgrades like Statkraft’s Greener Grid Parks, the national grid will struggle to adapt.
Great Britain operates the fastest decarbonizing electricity system in the world. Our greener grid parks deliver a solution to the engineering challenge of removing fossil fuels from the UK's energy supply and maximising the amount of renewable energy that can be distributed through the grid.
This helps protect the environment whilst also reducing costs to consumers.
Our grid network needs to keep up with the rapid progress renewables has made in the UK. Sometimes National Grid, as the electricity system operator, has been forced to shut down wind farms and run gas power stations to keep the system stable. More projects like this one at Coylton will mean that running gas powered stations will become a thing of the past.
The Coylton site has been selected because:
- It is one of the locations preferred and targeted by National Grid Electricity System Operator (ESO)
- It has a 275kV connection option to the existing substation.
- It is located at a transmission network bottleneck (Coylton- Kilmarnock circuits).
- It is in an area of high wind generation and export (south west Scotland).
- The proximity to the existing Coylton Substation allows for the development to cut down on lengthy transmission cables and minimise disruption
- The Site is also assessed in the planning application to ensure that the location is suitable in regards to impact on any receptors.
Indicative designs of the proposed development are available to view in the Project documents folder.
Yes. We have two Greener Grid Parks operating in Keith, Moray and at Lister Drive, Liverpool. The technology used in these projects are synchronous compensators rather than the battery technology we are using at Coylton. We are currently constructing Neilston Greener Grid Park, just south of Glasgow, which will use the same battery technology as Coylton. We also operate two battery projects in Ireland as well as operating several projects in the Netherlands and Germany.
This project does not rely on any nearby electricity generating projects (Solar, Wind etc) to operate.
The batteries will store, import and export energy which will facilitate the decarbonisation of the UK’s electricity supply. It is not possible in advance to say where it was generated. However, in general we would expect batteries to charge at times when there is a surplus of renewable energy generation in Great Britain.
The development will grid-forming converters combined with batteries, which always stay in ‘grid-forming’ mode. This means they inherently resist changes in voltage and frequency on the electricity grid. This is another innovative way we can provide stability to the grid.
Construction began in July 2024.
Between 12- 18 months.

Environmental considerations
The preservation of biodiversity and wildlife onsite is a top priority for Statkraft, which is why we are committing to provide ecological enhancements on all our Greener Grid Park sites.
We have consulted with East Ayrshire Council throughout the pre-application stage and have produced a Landscape Planting Plan to demonstrate the new boundary planting to accompany the Development.
As a global energy company, strategically focused on scaling renewable energy solutions, we believe that we can be instrumental in driving progress toward achieving the UN Sustainable Development Goals (SDGs) by 2030. Though we have numerous initiatives that can be linked to different SDGs, our positive impacts are naturally concentrated around the goals for Climate Action (SDG 13). We contribute directly to climate change mitigation by displacing fossil fuels whilst meeting growing energy demand.
The planning application includes a Drainage Impact Assessment including the provision of sustainable drainage measures. The Site is not designated as likely being of risk from any type of flooding.
The site will be fenced off using high security fencing at a minimum of 2.4m high. We have consulted with the Council on the colour of the fencing to ensure it blends in with the natural landscape and adjacent substation.
The building colour is moss green, selected due to its ability to blend in with the environment.
Construction & Transport
Once the facility has been constructed, there will be minimal vehicle trips to the site during the operation of the development. There will be occasional visits for maintenance and inspection of the facility but the site will generally be unattended, so there will not be noticeable impact on traffic flows in the area.
Our construction access route will minimise the impacts on local residents along with methods such as carefully scheduling deliveries as set out in our Construction Traffic Management Plan. Please click here for more information on the traffic management measures we are undertaking at Coylton.
Details of the route to site, vehicle movements and mitigation measures are provided in the Traffic Management Plan prior to construction. Main roads will be used as much as possible to avoid traffic flow through towns and villages.
Abnormal load vehicles will arrive at night to avoid disruption to traffic flow in the area. HGV delivery timings and any restrictions will be agreed with the Council and Highways and conditioned via the Traffic Management Plan.
Service personnel will drive to site in small vehicles so there will be discernible impact to existing traffic levels. We do not envisage any HGV’s visiting the site in the first few years of operation, and will only be required for major refurbishments if required.
During construction, Statkraft will pay full regard to the best practicable means available in respect of the control of noise from the site and weekend working will be in adherence with the Council controlled conditions.
Local Benefits
The innovative grid stabilising technology planned for Coylton will provide the national grid with ancillary services, such as inertia, using zero carbon infrastructure.
A grid without inertia is one that is unstable, suffers from issues of power quality. Great Britain operates the fastest decarbonizing electricity system in the world. Our greener grid parks deliver a solution to the engineering challenge of removing fossil fuels from the UK's energy supply and maximising the amount of renewable energy that can be distributed through the grid.
In addition, National Grid spend millions per year stabilising the grid by turning fossil fuel plants on, but with this revolutionary technology at Coylton, we can save consumers money whilst supporting National Grid’s target to operate a zero carbon grid by 2025. The system operator, NGESO, state that their Stability Phase 1 Pathfinder Tender would save consumers up to £128m. You can find out more about the need for grid stability services on the National Grid ESO website(External link).
With Greener Grid Parks providing grid stability, this reduces the need to turn on fossil fuel power stations - so this project will also significantly contribute to the UK Government’s 2050 Net Zero target.
In addition to the economic and environmental advantages this project will bring, there will be local benefits in terms of jobs and business growth during construction. There is also an opportunity to consider educational gains and other benefits the development could potentially deliver – we would be happy to discuss this further with you.
Yes. We have a local suppliers registration link on the website so please complete that if you are a local business and interested in the project, or would like to recommend one.
We will work with groups such as the Chamber of Commerce to maximise opportunities for local suppliers.

Emergencies
At Statkraft we ensure that our battery projects have robust fire protection systems. Exact solutions vary depending on the supplier, but this might typically involve a non-toxic inert gas such as Argon or a fire suppressing foam being pumped into a battery container to cut off the supply of oxygen to a fire. Batteries and other equipment are separated by a buffer zone to prevent fires from spreading.
We will also have a fire safety plan in place with the local fire service.
Our battery monitoring system monitors individual cells within the batteries twenty-four hours a day. These adjust the cooling and power systems for the batteries, so they operate safely and efficiently. They can also alert operators to the health of individual battery cells, so appropriate maintenance carried out so soon as any changes are detected.
The battery monitoring system can also make sure that electricity can be quickly shut off to the site if a fire is detected.
Safety is our priority, which is why all of our sites are fitted with controls which monitor the site 24/7 and can remotely shut down the system.
There will be stringent emergency measures in place, which are outlined in the emergency plan produced before construction starts. In addition, we will have Senior Authorised Persons (SAP) with sufficient competence who will be responsible for the site.
We will also engage a local security company to respond to security alarms within a set time frame.
Some examples of measures we would take include:
- To separate transformers from adjacent structures and from each other.
- Resistance barriers (fire wall), spatial separation, and provided with an enclosure.
- Automatic fire, gas and smoke detection (beam based) within the buildings.
- Automatic fire suppression (e.g. water and/or gas-based sprinklers) within the buildings.
- Use of fire-resistant non-combustible materials/enclosures around the components.
- 24/7 remote control of the temperature of the components.
- Regular maintenance and testing of BESS
A detailed design risk assessment with specific and detailed risk mitigation will be carried out at the design stage. Fire safety measures will be detailed within the planning statement and will be detailed further within the fire safety strategy report with the input from all suppliers and the Statkaft operations team.
Statkraft will implement procedures and plans for emergency situations and will run regular emergency preparedness exercises in order to ensure that all personnel in the organisation, including third parties, are aware of how to act and react if any unplanned situations should occur.
Cooperation will be established with local emergency services to ensure there is an understanding of the technology and fire safety plan put in place.
