Registry Bridge

Any renewable energy registry. One platform, one API.

Most EAC registries weren't built to be connected: archaic government portals, no public APIs, country-by-country quirks. Soldera's Registry Bridge connects to them all.

Source, transfer, cancel, and export audit-ready local-cancellation documentation across 30+ national registries, without leaving your browser window.

One integration. Every EAC market unlocked.

Soldera's Registry Bridge enables full-function integration with every EAC registry, including heavily gated registries without an API. Our platform is the wrapper that smoothens operational friction into one workspace, enabling your team to execute on sustainability strategy in new markets without local registry accounts or market knowledge.

Use Soldera's platform directly or connect through API endpoints if your EAC operations need to sit inside your own ETRM, EMS, or reporting system. Soldera's system spans all EAC types, enabling your team to procure, manage and cancel in specific local registries, providing exportable cancellation statements tied to the exact market of consumption.

LOCAL PROOF

Credible claims are cancelled locally

Local registries exist for a reason. Cancelling EACs in a registry that doesn't correspond to where consumption actually occurs, known as ex-domain cancellation (EDC), is not a compliant workaround. And, because geographic matching requirements are tightening across major reporting protocols, EDC is attracting more scrutiny than ever. That means cancellation routes will face more audit pressure going forward, with auditors looking for appropriate cancellation pathways. Soldera's cancellation auto-routing executes against local registries based on your actual consumption sites, with local cancellation statements ready for export where available.

RE100

EECS rules are referenced for EDC, and certificates must be cancelled in the correct market boundary where consumption occurs for the applicable disclosure use case.

Best practice: Cancel in the registry of consumption

Other than market boundary adherence, RE100 makes no provision for local cancellation and defers to EECS judgment. In practice: EECS-GO issuance is a qualifying characteristic of a country's inclusion in RE100's European Market Boundary "The Single Market In Europe".

Exceptions are also explicitly made that permit EDC as the viable path for European micro-states, countries without independent registry architecture. EECS rules define all other cases where EDC is technically permissible, nearly always requiring cancellation in the registry that corresponds to where electricity is consumed.

EECS Rules

The AIB-Hub exists to ensure interoperability and registry transfers. Permissible EDC is therefore, not-unsurprisingly, incredibly rare.

Best practice: Transfer first, cancel locally

EECS rules require that a GO is exported to the registry corresponding to where consumption occurs before it is cancelled. Cancellation in the registry of issuance while claiming in a different domain is not permitted as a standard mechanism.

The only exceptions require conditions that must be met simultaneously: physical energy export between nations, technical difficulties preventing transfer, and notifying the local issuing body. EDC is not a recognised substitution for this process, but a niche carveout for when AIB-Hub transfers are impossible.

Local Rules

Many jurisdictions forbid ex-domain cancellation outright, while others apply stricter national rules on top of the EECS framework.

Best practice: Stay consumption-market compliant

The valid cancellation path depends on the market where electricity is consumed: supplier status, named beneficiaries, disclosure use cases, deadlines, and temporal matching can all affect whether the cancellation supports the claim.

Local restrictions may go beyond baseline EECS rules, such as requiring supplier status to cancel, but these are not "confirmed technical difficulties" that support bypassing destination-registry cancellation.

Why teams use it

EAC work thrives with better infrastructure

Traditional approach

Execution history gets hard to prove

Work is scattered. When certificate actions sit across portals, inboxes, and spreadsheets, sustainability back-office teams spend hours building a clear audit trail.

With Soldera

Full visibility over your EAC portfolio

Centralised actions and a clear audit trail make it easier to track who executed what, which certificates moved, and which evidence was produced.

Traditional approach

Intermediaries set the pace

Broker and consultant-led transfers means waiting for the ritualistic back-and-forth with counterparties to end before you can execute your cancellations.

With Soldera

Instant execution across registries

Soldera's registry bridge and 4000+ production facilities under EAC management mean you can procure, manage, and cancel EACs immediately without waiting for a human to pick up the phone.

Traditional approach

Evidence gets assembled too late

Rather than automatic document assembly, sustainability teams often reconstruct cancellation statements, transaction records, and certificate metadata as the reporting deadline is closing in.

With Soldera

Audit-ready from the start

The platform is built so that evidence is structured during execution rather than assembled after the reporting deadline.

Registry Bridge FAQ

Who is this built for?
Registry bridge is built for corporate sustainability, energy procurement, finance, and emissions reporting teams that need reliable EAC execution across multiple markets.
Which EAC actions are supported?
Registry Bridge is designed around the full operating lifecycle: buy, receive, send, sell, cancel, and export evidence.
Does this replace local registry accounts?
In many workflows, hosted account control eliminates the need for your team to operate local accounts directly. If you already have registry accounts, you may choose to keep them open, as we provide simple integrations to the Soldera platform, but you will likely find it is easier to use Soldera hosted accounts across all of our supported regions.
Can we use Soldera's Registry Bridge without building an API integration?
Yes. Registry bridge is the infrastructure built into our cross-border EAC management platform, and corporate teams can use the Soldera platform directly. For more advanced use-cases, API workflows are available, such as when certificate actions need to connect into internal systems.
Can Soldera connect to every registry?
Registry Bridge is the infrastructure layer behind Soldera's platform, which can connect to every registry. We have existing integrations for 30+ registries and are rapidly expanding. If after signing up you require an integration that we do not have, please write to us via our helpdesk (the chat icon in the bottom right, visible on our website and inside our app). Alternatively, you can write to support@soldera.org.
Can Soldera connect to European GO registries?
Yes. Registry Bridge connects Soldera to all national Guarantee of Origin registries across Europe, including registries with no public API, each of which required a proprietary connector built through years of registry-by-registry technical work. New registry connections are added on an ongoing basis. If after signing up you require a connection not listed here, contact us via our helpdesk (the chat icon in the bottom right, visible on our website and inside our app). Alternatively, you can write to support@soldera.org.
