battery storage.

the scheme.

Boom Power is proposing a new Battery Energy Storage System (BESS) located at Carrog Ganol, near Cemaes, at the postcode LL66 0AY. The proposed BESS will cover an area of 5.7 acres (2.3 hectares).

Battery storage technology has a key part to play complementing renewable energy sources such as solar and wind. Supporting the grid with frequency response and reactive power before, during and after a fault on the grid. This would mitigate any risks of local blackouts on the local electricity network.

At a local level this scheme will support the Council’s strategic vision for rapid decarbonisation to build climate resilience. At a national level, the UK Governments energy security plan, Powering Up Britain (March, 2023), seeks to improve national energy security, create greater energy independence consistent with net zero and reduce the risk of higher electricity bills. In addition to this, the Welsh Government has recently set out targets for Wales to meet 100% of its electricity needs from renewable sources by 2035. This will require a rapid and expanded deployment of low carbon power, supported by Battery Energy Storage Systems (BESS).

We are engaging with an Anglesey based social enterprise with a view to delivering local benefits.

LOCATION – why here?


Tackling climate change requires unprecedented and urgent action. To thrive, the UK will need to support the growth of new sectors. The transition to powering our homes and businesses with low-cost, low-carbon electricity generated from renewable energy sources is an essential part of the UK’s climate change strategy and needs to be delivered at pace and scale.

Brownfield and rooftop solar schemes are rightly being developed however these schemes cannot deliver at the pace or scale required to meet net zero. Many brownfield sites are not available for development or may not be suitably located for connection of an electricity generation project into the high voltage electricity grid.

It will therefore need to be a mixture of projects on suitable and available brownfield, rooftop, and carefully selected and designed projects on greenfield sites, such as this scheme, that will be required to deliver the energy transition in the UK.

This site has been carefully selected as part of a detailed feasibility process. Consideration has been given to a number of factors including:

Detailed studies are being carried out by technical specialists to inform the final scheme design to respond to each of these points.



This scheme will assist the Council’s ambition to deliver zero carbon emissions by 2030 whilst delivering a completely carbon neutral area by 2050 to align with local and national targets. This scheme will therefore contribute to the UK’s urgent need to transition to a sustainable, clean future.

Local highway restrictions will be followed and a construction traffic management plan will be agreed with the local highway authority to ensure that our construction plans are appropriate.

Supporting the natural landscape, we use existing access tracks where possible, design around existing trees and hedgerows whilst planting additional screening to support the rural aesthetic of the existing landscape. Therefore, whilst there is an initial change to the countryside, upon operation, this scheme will fast become a haven for wildlife. An assessment of the landscape and visual impacts will be undertaken by an external landscape architect to ensure our scheme protects the character and beauty of the countryside.

This is a temporary, fully reversible development. At the end of the project lifespan, equipment will be removed, and the field can return to its current condition. This explicitly means that the status of the land once decommissioned will not be classified as a brownfield site and will retain greenfield status, protecting the land from other forms of development. It is impossible to say if the same planning processes will be in place at the end of the project lifespan, however, under the current planning legislation, if anyone wants to build on the same land upon decommissioning, a new planning application will need to be submitted.

The complete battery system is extremely advanced with cutting edge technology, but when broken down, the individual lithium-ion battery cells are exceptionally similar to those found in many products, such as battery drills, battery hoovers and even battery cars, the difference being that there are many thousands / millions of them grouped and managed together.

Battery storage is either coupled to renewable energy sources or it is directly connected to the electricity network. This project is a stand alone facility directly connecting to the grid. At times when there is surplus electricity available, the batteries are charged, this allows the energy to be discharged or called upon by the electricity network on demand for both emergencies and grid balancing (keeping the grid stable, responding to sudden changes or fluctuations). Additionally this would be to simply meet the daily peak demand, usually around 6pm when most cookers, kettles and even 1st generation battery cars and chargers all start demanding electricity.
