BESS - for applicants, designers and planners

Before you apply for planning permission...
At the beginning of your project please get in touch with our Fire Engineering Team (FET) when we can arrange to discuss your application, design and plans with you before any submissions are made.
This will enable us - if necessary - to work with you prior to submission in order help you to check your project meets the requirements set out in the NFCC Guidance before submitting it to the planning authority.
The information we will need prior to submitting your application ...
The following list is intended as a guide, but dependent upon the nature of your site, we may need additional information not listed below :
- outline how your proposed site meets the recommendations contained in the NFCC Guidance for Fire and Rescue Services
- where applicable, provide details of how you will deal with risks that may arise as a result of your proposal deviating from the NFCC Guidance, or other international design codes and industry best practise
- clearly establish and identify who is at risk at the proposed site in the event of thermal runaway
- give early consideration to, but not limited to, the following information:
- identify any surrounding communities, sites, and infrastructure that may be impacted as a result of an incident
- provide us with a detailed diagram / plan of the site
- how KFRS appliances can access the site in the event of an emergency
- provide evidence that site geography has been considered (e.g. prevailing wind conditions)
- how the BESS units will be laid out relative to one another
- details of fire-fighting water provisions (e.g. flow rates, static tanks, hydrants, fire mains). See p.8 of the NFCC Guidance for further information
- your intended fire strategy in the event of thermal runaway (e.g. controlled burn with boundary cooling or internal water suppression)
- an outline emergency response plan (ERP) reflecting the guidance provided by the NFCC
Towards project completion
Towards project completion we will need the following information, as set out in the NFCC Guidance. The provision of this information enables us to compile the basis of a Site Specific Risk Information (SSRI) assessment. This will then be used to formulate an emergency response plan which can be made available to our crews.
(Note: due to the rapidly changing nature of the technology KFRS recognise that the procurement of technology may be left until the later stages of a project.)
Please provide the following:
1. The battery chemistries being proposed:
For example: Lithium-ion Phosphate (LFP), Lithium Nickel Manganese Cobalt Oxide (NMC)).
We need this because:
- battery chemistries will directly affect the heat released when a cell goes into
thermal runaway - battery chemistries will influence vapour cloud formation.
- an understanding of the battery chemistry is useful when requesting scientific
advice during an incident.
2. The battery form factor (e.g. cylindrical, pouch, prismatic)
3. Type of BESS e.g. container or cabinet
4. Number of BESS containers/cabinets
5. Size/capacity of each BESS unit (typically in MWh)
6. How the BESS units will be laid out relative to one another.
7. A diagram / plan of the site.
8. Evidence that site geography has been taken into account (e.g. prevailing wind conditions).
9. Access to, and within, the site for fire and rescue service assets
10. Details of any fire-resisting design features
11. Details of any:
- fire suppression systems
- on site water supplies (e.g. hydrants, EWS etc)
- smoke or fire detection systems (including how these are communicated
- gas and/or specific electrolyte vapour detection systems
- temperature management systems
- ventilation systems
- exhaust systems
- deflagration venting systems
12. Identification of any surrounding communities, sites, and infrastructure that may be impacted as a result of an incident.

Finally ...
please don't forget to notify KFRS via the FET email, when
- Site construction begins
so that we can update our system and make crews aware of site access location(s).
- Following delivery of the initial phase of BESS containers
so that we can update our system of the potential increased risk at the site.
- Project completion/activation
so that our Risk Inspection Team (RIT) can complete a Site Specific Risk Information (SSRI) visit and align our operational response with the applicant’s emergency response plan (ERP).
BESS with permanent buildings
Where the proposed BESS site is being designed with permanent buildings, the consultation would be reviewed in the normal manner against Approved Document B: Volume 2: Buildings other than dwellings 2019 edition which includes vehicle access and facilities for firefighters.
If this is the case, KFRS would expect to receive plans and documentation including fire risk assessments via our Fire Engineering Team in the normal manner from a Building Control body.
Security of information
The information we request from you will be used to both aid in the design process and influence the emergency response at an incident.
We acknowledge that:
- some specific details may be commercially sensitive, and so the information requested is kept in confidence on our secure system throughout
- some key features of the design may not be finalised in the early stages of (pre) planning, due to evolving technology and/or procurement of equipment
- any data shared with us will be processed in accordance with our privacy notice for regulation and consultation with businesses
