Artificial Intelligence

Market infrastructure for critical power equipment

Accelerate your energisation
without the guesswork.

Accelerate your energisation
without the guesswork.

Supply chain intelligence, slot management, and portfolio orchestration for faster energisation, without stranded equipment or balance sheet risk.

When do you need to energise by?

Fast power-to-market

A panel of approved OEMs, pre-checked for UK and EU grid connection. Real availability up to 40% faster than going direct.

Flexible payment

We pay OEM upfront costs. You pay us as your project draws down.

Slot reservations

Reserve a slot before you commit. Move it if plans change. We carry the supply risk.

Supply certainty

Independent market intelligence. Real-time factory loading, lead time benchmarks to help you plan ahead.

Who we work with

Growth is increasingly gated by access to long-lead power equipment.

If critical power equipment is on your critical path, we should talk.

Data centre operators

Verified HV equipment, payments that move with your project, and a place in the queue before you have to commit to a spec.

Renewable developers

HV lead time is your fundability problem. Verified supply, pre-FID slot reservation, and payments aligned to your draw schedule.

Industry

Secure critical power equipment for expansion or replacement without a multi-year wait behind data centre demand.

What we do

Turning power procurement from a constraint into a growth lever.

Opna is market infrastructure for critical power equipment. Three capabilities, one outcome: faster energisation without stranded equipment or balance sheet risk.

Supply chain intelligence

We maintain a global OEM panel of who can build what, to which grid code, and in what window.

Better visibility on feasible OEMs, lead times, and site-specific delivery options

Slot management

We hold manufacturing slots across the panel, for specific voltage classes, and convert them when you're ready.

Earlier access to critical HV/EHV equipment and lower risk of RFS delay

Portfolio orchestration

We sequence your whole bill of materials across manufacturers so it lands together, on your site, on your desired date.

We sequence your whole BoM across manufacturers so it lands together, on your site, on your desired date.

Optional execution support that complements in-house OFCI capability

How it works, step-by-step

Flexible slot management.

Reservations across the BOM, either forward-looking or working backwards from our available slots. You get in on day 0, instead of much later.

1. We hold class-based slots

Opna holds manufacturing capacity with our OEM partners, against standardised voltage classes.

2. You reserve your programme
3. Slot converts to P.O.
4. Upon P.O. you are the buyer of record
5. You pay against milestones

Our take on the coordination and market infrastructure this industry needs.

The immediate bottleneck

It's not just a supply problem. It's a coordination issue.

Order books are full. Lead times are running at 3+ years. Standard procurement requires capital commitment and freezing designs before your project is ready. Let's change that.
