Boom Power is constructing a Battery Energy Storage System (BESS) on approximately 2 acres of land, located in North Baddesley, Hampshire, at the postcode SO52 9LY.

The project would provide capacity to store around 114 megawatt-hours (MWh) of energy, allowing discharge of power for a period of up to 2 hours, for distribution to the grid. It is important to note that this project is non-subsidised, therefore, requires no government or public funding.

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 and flood risk. Detailed studies have been carried out by technical specialists to inform the final scheme design and respond to each of these points.

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.

Features & Benefits.

The proposals have been carefully sited and designed in order to work with the existing landscape in order to deliver key benefits in reducing the visual impacts of the proposals and providing ecological benefits above baseline conditions.

The proposals include planting of trees and hedgerows around the northern, southern and western perimeter of the battery compound and within the gaps of the existing field boundary. This planting would strengthen the existing habitat connectivity and would screen the proposals from the adjacent highway, particularly as the planting becomes established beyond year 5 of its implementation.

On the land to the north of the battery compound there is a 1.1 acre wildflower meadow (0.45 hectares) would be planted, delivering a biodiversity net gain of approximately 15%. 

The anticipated construction period will be approximately 6 months.

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.



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 Government had made a legal commitment to cut carbon emissions to net zero by 2050. 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.
