Our proposed battery energy storage system is on approximately 2.3 hectares of land, located at Carrog Ganol, near Cemaes, at the postcode LL66 0AY. The project will have the capacity to store around 660 megawatts-hours (MWh) of energy, allowing discharge of power for a period of up to two hours. This is equivalent to the electrical needs of 83,069 family homes for a two hour period per day.

This site has been carefully selected as part of a detailed feasibility process. Consideration has been given to a number of things including: Residential amenity, grid capacity, environmental designations, cultural heritage, ecology, biodiversity, flood risk and agricultural land quality. Detailed studies are being carried out by technical specialists to inform the final scheme design and respond to each of these points.

The site is in a hollow, so natural topography screens the development. Care has been taken to ensure that the site is not visible from the Area of Outstanding Natural Beauty (AONB) to the north.

We understand why some people would prefer for battery energy storage systems to be developed on brownfield sites, however, brownfield is inherently more suitable for residential or other commercial developments.

Project Selection







Battery storage technology has a key part to play complementing renewable energy sources such as solar and wind. 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.


The development and associated landscaping proposals have been designed to provide enhanced biodiversity gains for the local area, above the baseline conditions.

The proposals will include a range of environmental enhancements which would screen the development from the nearby public right of way and would improve habitat connectivity with the adjacent woodland.

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

Planning permission would be sought for a temporary consent and the scheme would be fully decommissioned at the end of the project’s operational timeframe. The development would not change the status of the land for planning purposes following this period and it would therefore be returned to agricultural use.

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.



A significant increase in renewable energy generation is supported by national and local planning policy and commitments. The UK Government has committed to reducing economy-wide greenhouse gas emissions by at least 68 percent by 2030, compared to 1990 levels.

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 recognise the importance of environmental protection and betterment as part of our commitment to operating sustainably and responsibly. We procure independent qualified ecologist advice to measure the biodiversity value of each project and to design enhancements to deliver a net biodiversity gain.

Public Consultation EVENT.


Boom Power agree with the guidance issued by the UK Government’s Chief Planner, which emphasised that planning applications that positively impact the country and local communities must continue to come forward.

In addition, Boom Power believes that it is vital that local communities are able to see and shape planning applications that may have an impact.

Our public consultation event was held on Tuesday 28th February 2023 from 1pm – 6pm at HWB Cemaes, Lôn Glasgoed, Cemaes, LL67 0HN. This gave the opportunity to meet with our project team, learn more about our proposal and see our plans.  Thank you to all for attending!
