Before any BESS site goes live, the basics need to be in place – access, infrastructure, welfare and toilets. Miss them, and the project slows down fast.
Whether you are planning a battery energy storage project, managing early works, or mobilising contractors to site, this guide explains what needs to be in place before construction starts.
• Welfare units delivered fast
• Toilets installed and serviced weekly
• Off-grid power ready (no generator needed)
• Remote sites covered nationwide
• Sites operational from day oneBottom line: No setup = no site progress.
Quick Summary (for planners, PMs & contractors)
BESS site setup involves preparing a construction-ready environment before battery installation begins. This includes access, groundworks, grid connection infrastructure, and essential welfare facilities such as welfare units and portable toilets.
Most sites are remote and off-grid, which makes early setup critical. If welfare, toilets and servicing are not in place before teams arrive, delays come quickly.
What is a BESS Site?
A Battery Energy Storage System (BESS) site stores electricity for later use, helping support renewable energy generation, grid stability and peak demand management.
Before any battery units are installed, the site must be fully operational – meaning workforce-ready, compliant and serviced.

Who Builds a BESS Site?
BESS projects involve multiple specialist contractors working together.
- Developers – fund and own the project
- EPC contractors – manage delivery
- Civil engineering teams – handle groundworks and access
- Electrical & grid specialists – manage infrastructure and connection
Grid and electrical infrastructure is typically handled by specialist contractors such as Radix Group, working alongside civil teams on live energy and infrastructure projects.
What Needs to Be in Place Before Works Start?
BESS construction does not begin with installation – it begins with early works and site setup.
- Access routes and haul roads
- Ground preparation
- Temporary compounds and security
- Cabling routes and trenching
- Grid connection infrastructure
- Welfare facilities and toilets
Miss any of these, and the project slows down immediately.
That is why contractors typically arrange site welfare facilities and portable toilet hire before major works begin.
Reality on site:
Most delays do not come from major works – they come from missing basics like welfare, toilets and servicing not being in place when teams arrive.
Site Constraints (Why BESS Sites Are Different)
BESS projects often come with a set of site conditions that need thinking about early.
- Remote or semi-rural locations
- Off-grid during early phases
- Restricted access
- Fast mobilisation requirements
Everything must be in place before the workforce arrives.
These challenges are similar to other infrastructure projects such as solar farm site setup, where early planning makes the difference between a smooth start and a delayed one.
Welfare Requirements on BESS Sites
One of the most common early-stage failures on infrastructure sites is inadequate welfare setup.
Typical issues
- No welfare units in place at mobilisation
- Too few toilets for workforce size
- No servicing schedule
What this causes
- Delays
- Compliance risks
- Poor working conditions
For most projects, the answer is straightforward: get the right welfare unit hire and toilet provision in place from day one.
Toilets and Welfare – What’s Required?
Typical BESS site requirements usually include:
- Portable toilets delivered and installed
- Welfare units with canteen and drying space
- Weekly servicing and waste management
- Handwashing and hygiene facilities
On remote BESS sites, this is not optional – it is critical infrastructure.
For projects looking to reduce generator reliance, solar-powered welfare units are often a strong fit.
Off-Grid Sites (No Power, No Problem)
Most early-stage BESS sites do not have mains power.
That is why solar welfare units are increasingly used:
- No generator required
- Silent operation
- Ready to use on delivery
- Lower running costs
See our 12ft single toilet ecowelfare unit for a typical off-grid setup.
Access and Logistics
BESS sites often involve practical delivery challenges such as:
- Narrow access roads
- Temporary haul routes
- Restricted delivery windows
Your supplier needs to handle delivery, positioning, servicing and ongoing support without disrupting the site.
BESS Site Timeline (Typical Phases)
- Early works
Access, clearance and welfare setup - Groundworks
Foundations, trenching and infrastructure - Installation
Battery units and systems - Commissioning
Testing and grid connection
Welfare and toilets are required from phase one.
What Gets Missed (And Causes Delays)
- Late installation of welfare units
- Too few toilets for the workforce
- No servicing plan
- Underestimating remote conditions
Small oversights that stop large projects.
On energy sites, these are often the basics that get overlooked while attention is focused on civils, electrical works and programme deadlines.

Frequently Asked Questions (BESS Site Setup)
What is required to start a BESS site?
Access, groundworks, grid infrastructure, welfare facilities, toilets and servicing arrangements must all be in place before work begins.
Do BESS sites need welfare units?
Yes. Most sites use dedicated welfare unit hire to remain compliant and operational.
Are BESS sites usually off-grid?
Often, yes. This is why solar welfare units are commonly used.
How early should toilets be installed?
Before the workforce arrives. Early setup prevents delays and compliance issues.
