An energy ally to the grid, consumers and the planet

29/10/2026

A fuel tanker and a petrol pump both hold fuel. Nobody mixes them up.

Battery storage and a battery charger get mixed up every day. Since Tuesday’s launch, the most common question has been which one a depot needs.

MAX stores. MEV charges.

The MAX300 is the tanker. Storage that goes where the energy is needed: under 3.5 tonnes on its own trailer, towed by a van or pick-up on an ordinary car licence. It powers sites, feeds a row of separate chargers, or charges vehicles itself with integrated DC fast charging up to 400kW

The Allye MEV is the pump, with its own tank underneath. It stays at the depot, fills slowly from the supply you already have and is designed to charge two vehicles at once at up to 200kW or 300kW. It is a charger and nothing else.

The rule of thumb:
If the energy needs to move, between sites, to a construction compound or to a row of existing chargers, it is a MAX.
If the charger stays put and only ever charges vehicles, it is a MEV.

Many fleets will end up with both. J & M MURDOCH & SON LTD’s MAX300 has fed DC fast chargers from a 32A supply since March. A depot with no chargers yet could start with a MEV and add a MAX when the next site opens.

Most fleets do not need a bigger connection. They need to decide whether their energy moves or stays.

Save this for the next time someone asks.

A 22kW supply cannot run a 400kW charger.
Today it can.

Allye have launched the Allye MEV, the first dedicated battery-buffered EV charger built using entire repurposed EV batteries. It is designed to deliver up to 400kW from the supply your depot already has. The MEV200, one of two launch models, is just £70,000, changing the game for battery buffered ultra-rapid EV chargers.

Most depots are not short of energy. Vehicles sit at base overnight, and even a modest supply can refill them. What depots lack is power when the vehicles come back, and the usual fix is a grid upgrade: six figures and up to three years of waiting.

MEV stores energy slowly and releases it fast. No grid upgrade, no network application, and an installation designed to take under two hours. When the lease ends, it moves with your fleet.

Round 2 of the Depot Charging Scheme is expected to open tomorrow. If your bid is waiting on a grid connection, it no longer has to. We can help deliver power in minutes not years.

The Depot Charging Scheme will pay for most of your chargers. It will pay nothing towards the power to run them.

Window 1 covered 70% of chargepoint and civil costs, up to £1m. Grid connection and reinforcement were not funded, and they are not funded now.

Picture the winning bid. Six new rapid chargers, mostly paid for, installed on a depot whose supply can run one of them at full power.

That is a supercar with a lawnmower’s fuel line.

It is not a hypothetical. Grid capacity was named the biggest obstacle to electrification by 47% of delegates polled at the Fleet Electrification Forum in July. TwentyForty puts a new depot connection at 18 to 36 months. Round 2 is expected to close on 29 January 2027.

Run the timeline. The grant arrives. The chargers arrive. The connection arrives a year or two later, if it arrives, at a price the scheme does not touch.
The bids that deliver will answer the question the form does not ask: where does the power come from?

There are two honest answers. Pay for a bigger connection and wait. Or store energy slowly from the supply you already have and release it fast when the vehicles come back. In Glasgow, J & M MURDOCH & SON LTD took the second route on a 32A supply and deferred a £300,000 upgrade.

The grant buys the charger. Storage buys the power to run it.

My prediction: a large share of Round 2 chargers will be installed before they can run at full power.

If your depot has been quoted for a grid upgrade, send me the quote.

897 charging sessions. 126 MWh delivered.

Twenty-tonne electric excavators on the UK's flagship infrastructure project. No grid connection. No diesel generator.

Lower Thames Crossing wants around 130 zero-emission machines working by 2028. The plant is solved. The charging isn't.

Since January, Allye MAX500s have charged 20-tonne electric excavators on the Bouygues Murphy JV site. Volvo, SANY and LiuGong machines, topped up at 240kW DC between shifts, working alongside GeoPura’s green hydrogen.

No grid connection. No diesel generator.

Diesel is muscle memory. The bowser turns up, the tank fills, nobody thinks about it. Electric plant asks a site team to plan energy the way they plan concrete. That is a habit change, not an engineering one.

So we’ve logged everything. Every session, every fault, every workaround, every question asked on the ground. Nine months of it.

This spring, government named energy infrastructure as one of four sectors where public money should back British industry. In the minister’s words, “it matters where things are made and who makes them.”

A British road, paid for by British taxpayers, partly charged by batteries that first drove on British roads.

So here’s the question for the next 120 machines: will the energy behind them be built here, or shipped in?

Congratulations to the Lower Thames Crossing and BOUYGUES UK and Murphy JV teams. Pathfinder projects are hard, and this one is working.

If you run electric plant and the power isn’t where the work is, the carousel shows how we do it.

£2 a litre.

Diesel passed it this week for the first time. The previous record of 199.09p had stood since June 2022.

If you run a generator, that's not a headline. It's an invoice.

A typical tank now costs around £110, nearly £32 more than in late February. Hauliers say they're paying an extra £250 a week per vehicle. With roughly 30% of UK diesel imported from the US, nobody can tell you where the price goes next.

Our customers stopped trying to guess. They cut their run hours instead:
→ Construction: Horizon Plant runs cranes on 70% less fuel
→ Infrastructure: four MAX500s power the Lower Thames Crossing without a grid connection, saving over £30k a week
→ Film and TV: OnBio cut generator fuel by 70% with a hybrid setup
→ Fleets: J&M Murdoch runs DC fast charging from a 32A supply

All of those savings were measured before diesel hit £2, so they're worth more this morning.

Every litre you don't burn is a price rise you don't pay.

What would you cut first: the run hours, the fuel bill, or the generator itself?

£30,000 an hour.

That's what a supermarket loses when the freezers warm up.

Most major supermarkets either have a diesel genset round the back or one on standby for deployment in under an hour (the image is Sainbury’s South Ruislip store). They have to be maintained, serviced, and refuelled. Producing absolutely nothing.

An asset that exists to protect against a failure that might never come.

Here's what almost nobody in retail energy procurement is actually calculating:

Every diesel genset behind a supermarket is a stranded asset. It costs money to keep. It generates nothing. It's the accounting equivalent of parking a Range Rover outside every store, engine running on standby, in case one of the delivery vans breaks down.

Behind-the-meter batteries in our own supermarket case study are earning £37,000 in six months from grid-services revenue alone. Before diesel is displaced. Before freezer downtime is avoided. Before delivery EVs plug in overnight.

Same footprint. Two jobs. One asset that pays. One asset that costs.

Non-domestic electricity rose 6.4% year-on-year in 2025. Rising again in 2026. And every store in the estate is still paying to maintain a diesel that hopefully never turns on.

Standby diesel made sense when batteries cost 10x more and grid services didn't exist. Neither of those is true anymore.

The question isn't "should we have backup?" It's "why is the CFO still signing off backup as a cost centre?"

By 2030, the supermarket estates still on diesel resilience will be running the losing operating model in retail.

If you're a supermarket ops director defending a maintenance line for a genset that hasn't started in three years — how do you take that to the next board?

Ten years for a grid connection.

That's what UK data centre developers are now being told.

OpenAI publicly paused Stargate UK. Their stated reason: UK power costs, four times higher than the US.

Ireland's data centre moratorium redirected €7.8 billion of pipeline investment - to markets that could actually plug the racks in.

The UK connection queue surged from 41GW in November 2024 to 125GW by June 2025. Three times national peak demand. Sitting in a queue.

The villain isn't AI. It's the assumption that the grid we built for coal will power the next industrial revolution.

Dublin's new rule: no large new connection without on-site dispatchable power at 80% of demand. Data centres are being told to become grid infrastructure, not just consumers of it.

We talk about AI Growth Zones but Britain won't be in the AI race with current power costs and connection queues.

Battery energy storage is the only tool that scales in the timeline that matters. Modular. Deployable in weeks. Dispatchable at the grid's request. Revenue-generating when idle.

The question isn't whether Britain builds AI infrastructure. It's whether the AI infrastructure Britain builds is British - or built somewhere else and rented back.

8 hours.

That's the notice your business will get before the lights go out.

For the first time in Britain's history, the grid operator can now order rolling three-hour blackouts across the country - without needing government approval.

The rule came into effect on 14 August 2026. This isn't your typical The Telegraph rage-bait story, but covered on every mainstream outlet in the country now runs the same headline - even the Guardian and Independent (if that's your preferred read) - Blackout Britain.

Britain now has three escalating tools for switching the lights off:

→ NESO can disconnect 20% of power in 5 minutes to prevent grid collapse.
→ NESO can now trigger 3-hour rolling blackouts with 8 hours' notice - no ministerial sign-off required.
→ The Electricity Supply Emergency Code - still active, still never invoked - can ration up to 90% of demand in a prolonged crisis.

Only one of the three is new. It's the first that doesn't need a politician's approval.

The near-misses are already costing real money to every consumer on their bill, but the cost of a blackout could be even greater - particularly to the economy and businesses.

Now scale it to a country that actually goes dark.

Spain, 28 April 2025: €400 million lost in ten hours. 60 million people. Traffic lights dead. Hospitals on generators. Payment systems down. Trains stopped between stations. Not a cyberattack. Not renewables. A voltage collapse across a transmission network built for one-way power flow from big fossil plants - running today's decentralised, renewable-heavy system.

The same architectural problem Britain is running now.

Most UK businesses don't have a plan. Some do, but handle it with a diesel genset. MOT'd. Refuelled monthly. Producing absolutely nothing until the day it does - if it starts. That footprint could instead be a battery. Earning grid-services revenue every day. Stepping in the second the mains fails. Same footprint. Two jobs.

Four levers.

That's what Boston Consulting Group (BCG) named this week as the way to unlock 14 gigawatts of new UK data centre demand - and cut £35 off every household's electricity bill by 2035.

Every one of them describes what an Allye MAX does.

⚡ One: trade flexibility for an earlier connection. Curtail when the grid asks, run when the site needs. Our MAX range is designed for exactly this.

🏭 Two: unlock a market for powered land. Turn brownfield and constrained sites into viable ones without a full grid upgrade. An Allye BESS makes any site a powered site.

🔋 Three: let developers self-build. Skip the DNO queue by installing your own bridging infrastructure. Our units are grant-eligible, drop-and-go, deployable in hours.

Four: behind-the-meter power as a bridge to full grid capacity. Connect today, upgrade over time. This is the mechanism. It's why we built Allye.

The counter-intuitive maths in the BCG paper is now the mainstream consulting view: Britain's electricity bill won't fall until Britain uses more of it.

And Britain can't use more of it without batteries in the ground shaping the demand.

Every constrained site is a candidate. Data centres. Depots. Factories. Farms. Retail estates.

We've been building the exact bridge BCG describes since 2021. It's on the market. It's grant-eligible. It's in the field with J & M MURDOCH & SON LTD, Collins Earthworks Limited, Roadchef, JLR, Film and TV Services, Afanti Media Ltd and OnBio among others.

If a DNO has told you a decade for a connection — the bridge is already built.

Data Centers and 18%.

That’s the average amount of grid capacity a UK data centre actually uses of the connection it paid for.

Research from freight infrastructure body TwentyForty, analysing five million half-hourly meter readings across 96 data centres on UK Power Networks' grid. The typical site drew 18% of what it had booked. Over three years.

Meanwhile freight depots wanting to charge electric trucks - mostly overnight, when the network is empty - are waiting years in a queue that's ordered by paper reservation, not real use.

The queue isn't waiting on the wires. It's waiting on the accounting.

Almost nobody seems willing to call it out. We are handing electricity capacity to whoever asks for it first, not to whoever will actually use it.

The result is predictable. Diesel trucks stay on the road for another decade because the depot that ordered them can't get 500kW at 3am. Electric HGVs sit in factory yards waiting for someone in Ashford to get a connection date. A data centre in Slough uses 18% of a 20MW allocation and holds the rest just in case.

The grid isn't full. The queue is.

TwentyForty's report calls for flexible connections, freight in the strategic-priority criteria, and a statutory right for tenants to install charging where they fund it. All sensible. All years away.

Behind-the-meter storage is what closes the gap in the meantime. Charge slowly overnight at the connection you already have. Discharge at the peak the fleet needs. Trade during the day.

Every depot in Britain is a candidate.

If your electric fleet is waiting on a connection queue, are you waiting for the wires - or for the accounting to catch up?
