Engineering-led design
Bespoke systems designed by experienced power engineers, not adapted from catalogue products.
Complex made manageable
Custom hybrid power systems built to solve unusual load behaviour, space constraints and operational challenges.
Proven in critical environments
Trusted for infrastructure and high-risk applications where failure just isn’t an option.
When – and why – do you need a bespoke off-grid power system?
Most sites need power systems engineered to eliminate operational risk, noise constraints, safety exposure and single points of failure – our EasyGrid range of modular battery systems takes care of most of that. But what about extreme environments, restricted footprints, non-standard load profiles, sites with specialist safety requirements or those that require integration with existing plant? These cause headaches because the solution can’t be delivered by even the most advanced off-the-shelf unit. That’s when a bespoke off-grid battery energy storage system becomes the right approach. Energy Solutions designs and builds bespoke off-grid and hybrid power systems for highly complex commercial, industrial and infrastructure applications across the UK and internationally – because you deserve reliability, control and long-term performance, however challenging your environment.
Get a power system that meets the complex needs of your project
When an off-the-peg power solution meet the demands of the site, simply selecting a larger standard system isn’t the answer. The power infrastructure must be designed around how the site actually operates, not the other way round.
Scenarios where a bespoke Energy Solutions off-grid system can typically be used:
Non-standard or highly variable load behaviour.
Space-restricted or containerised installations.
Mission-critical or safety-sensitive environments.
Integration with existing specialised control systems.
Harsh, remote or tightly controlled operating conditions.
A bespoke Energy Solutions off-grid system is engineered from the ground up, combining:
Battery energy storage (BESS).
Hybrid generator integration.
Advanced load and energy management.
Remote monitoring and control.
Purpose-built enclosures or containerised solutions.
Site-specific electrical and safety design.
The result is a system that behaves as managed infrastructure, not just a collection of components, delivering predictable performance, lower risk and long-term operational confidence.

Our bespoke power engineering workflow
Discuss your application
We start by understanding your site, loads, constraints and operational priorities – not by trying to sell you a predefined product.
Engineering review
Our engineers assess feasibility, risks, integration requirements and long-term performance considerations.
Custom design
We design a tailored off-grid or hybrid power system, specifying storage, generation, control and enclosure requirements to suit your application.
Build & commission
Your system is built, tested and commissioned by our engineers, with full documentation, training and ongoing support.
Where bespoke off-grid systems deliver most value
Our specialist off-grid solutions are typically deployed in:
Infrastructure and transport environments.
Utilities and controlled-access sites.
Industrial facilities with non-standard loads.
Remote or high-risk operational locations.
Containerised or modular installations.
Applications requiring advanced control or monitoring.
If your project doesn’t neatly fit a standard category, it’s likely a candidate for a bespoke BESS solution.

Measured impact
Our clients consistently achieve 50%+ fuel and emissions reductions, meeting demanding ESG and sustainability benchmarks.
This approach allows EasyGrid to function as managed production infrastructure, reducing on-site disruption.
Specialist off-grid power solutions without compromise
Trying to adapt a standard system to a complex application often leads to inefficiency, operational risk and costly re-engineering later. A properly designed bespoke system avoids those pitfalls from the outset. If your off-grid power requirement is unusual, complex or mission-critical, the right next step is a conversation with one of our BESS specialist engineers.
