When will the renewed REV be available?

Expected in June or July 2026. Not all registration functionality may be available immediately at that point.

Do I lose EREs if the REV goes live later?

No. Deliveries from 2026 can be registered retroactively, no later than the last working day before 1 March 2027 (26 February 2027). Your evidence must, however, already be complete and reliable by then.

Does the deadline also apply to electricity?

Yes. The final registration deadline of the last working day before 1 March applies to all deliveries of renewable energy to transport from the previous calendar year.

What happens after the deadline?

Registration for that year becomes definitively impossible. Unregistered deliveries no longer yield EREs — there is no extension or late-filing option.

The renewed REV in 2026: deadlines and retroactive registration explained

Anyone supplying renewable energy to transport in 2026 is operating in an exceptional year. The Register Energy for Transport (REV) — the system in which deliveries are registered and EREs are credited — is being thoroughly renewed because of the transition from HBEs to EREs. According to the NEa, the renewed REV is expected to become available only in June or July 2026, and not all functionality may be live at that point.

That sounds like a reason to wait. It is in fact a reason to start now.

The hard deadline remains unchanged

The renewal does not alter the final registration term:

Deliveries made in 2026 must be registered in the REV no later than 26 February 2027 (the last working day before 1 March 2027). After that, registering 2026 deliveries is definitively impossible.

Deliveries can therefore be registered retroactively once the REV is available. But “being able to register retroactively” is not the same as “being able to arrange things afterwards”. Anyone who only starts collecting evidence in the autumn risks discovering that session data, meter readings or contract information can no longer be fully reconstructed.

What you should already be doing

The registration itself can wait for the REV; the evidence cannot. Concretely:

Record deliveries in a structured way from day one. Per delivery or session: kWh, date, EAN of the connection and the measuring instrument used. Ensure this data is stored immutably.
Use only approved measuring instruments. Without an MID-compliant meter, a delivery cannot be registered. Check your charger models in our charge point register, for example.
Preserve the evidence of the renewable share. For grid electricity, the grid-average share applies; for a direct line or renewable generation at the same address, you must be able to substantiate the 100% claim (guarantees of origin, contracts).
Arrange the operational chain. Who collects the evidence, who reviews it, who registers once the REV opens? When outsourcing: make sure the service provider is involved now, not just before the deadline.

Why deferral is expensive

Three effects make waiting risky:

Data rot. Session data from January is demonstrably harder to verify in November than when recorded immediately.
Congestion at the REV. If half the country registers half a year of deliveries simultaneously in autumn 2026, pressure mounts on the system, on verifiers and on support desks.
Year-boundary effects. Registrations in the period 1 January – 1 May are not credited immediately, but only after the year closure of the previous year. The later you register, the later EREs appear on your account — and the later you can trade them.
