Off-grid · standby · hybrid power · 10 kVA to 500 kVA
Power that doesn't stop when the grid does.
We design, install and maintain off-grid and standby power systems across the North East — from a rural home that wants to leave the grid behind, to a business that cannot afford to be dark for ten minutes.

What happens when the power goes off
Resilience is really a question about time. How long can you be without power, and how quickly do you need it back? That answer decides the equipment — and it is the first thing we work out with you.
The gap
Servers drop. Tills reboot. Process plant trips and needs resetting by hand. Most of the real cost of a short outage happens here.
Short outage
The commonest kind by far. A battery covers it silently, with no fuel burnt and nothing to start.
Long outage
Storm damage, a failed cable, a substation fault. Beyond what a sensibly sized battery will carry, so something has to generate.
No grid at all
Remote sites, new builds waiting on a connection, and homes choosing to run independently. Generation plus storage, sized to the load.
Already running a generator?
Most of what you burn produces nothing.
A set sized for your peak spends most of its life at a fraction of it — and a diesel at quarter load uses nearly twice as much fuel per useful unit as one working properly.
Our calculator shows you the figure for your own set, in about thirty seconds. It will also tell you plainly if a battery would not help, because on some sites it would not.
Try the calculatorBars show useful output per litre. A set at 10% load burns roughly three and a half times the fuel per unit that the same set burns working hard.
What we do
Six things, done properly.
We are electrical engineers who install renewables, not a generator shop. That means we size to your actual load, install to BS 7671, commission under load, and keep it running afterwards.
Off-grid homes
Rural and remote properties, and homes choosing to disconnect. Solar, battery, generator and sometimes wind, sized to run a house all year.
How it works →Business and site power
Container offices, welfare cabins, remote and temporary works. Power where there is no supply, or where a connection would cost more than it is worth.
How it works →Business resilience
Work out what an outage actually costs you, then cover it. UPS for the gap, generation for the length, and a plan that has been tested.
How it works →Home standby generators
Automatic backup for the house. Detects the outage, starts, transfers, and hands back when the grid returns. With or without renewables.
How it works →Diesel to hybrid conversion
Already running a diesel set? Adding battery and an inverter charger can cut run hours dramatically. Solar too, where there is room.
How it works →Combined heat and power
Take the heat the engine is throwing away and use it. For off-grid properties with a real heat demand, it changes the economics entirely.
How it works →How we work
Sized to your load, not to a catalogue.
Most oversized generators are oversized because nobody measured. An engine running at 20% load wet-stacks, wears badly and costs more to run than the right one would.
We measure what you actually use
Power quality metering and demand analysis on site where it matters. Starting currents, not just running load — that is what sizes the set.
Then we specify
Fuel, rating, control strategy, transfer arrangement, and how much of it should be battery rather than engine. Written down so you can compare it.
And we install it ourselves
Mechanical and electrical, to BS 7671, with earthing, protection and building control notification handled. Commissioned under load, not just started.
Why the hybrid question matters
A generator that runs less costs less.
The old approach was a bigger engine. The current one is a smaller engine and a battery — because most of the time your load is nowhere near your peak.
On a typical off-grid or standby site, the engine spends most of its life lightly loaded. That is the worst place for a diesel to be: poor efficiency, incomplete combustion, glazed bores and wet stacking. It also means fuel burnt and hours logged for very little useful output.
Put a battery and inverter charger in front of it and the picture changes. The battery carries the base load silently. The engine starts only when it is needed, runs hard while it is running, charges the battery, and stops. Fewer hours, less fuel, longer service intervals, and a great deal less noise.
Add solar where there is roof or ground available and the engine can go days without starting in summer.
The honest version
Hybrid is not automatically right. It suits sites with a low base load and occasional peaks, and sites where noise, fuel logistics or emissions matter. A site that runs flat out all day is better served by a properly sized engine and nothing else. We will tell you which you are.
Tell us the problem, not the product.
What you are trying to keep running, for how long, and where. We will work out what that takes.
