From Audit Trail to Settlement Deflating the Hype, Defining the Terms, and Mapping a Realistic Path for DLT in Balancing Markets

Fourth article in a series on regulatory innovation in energy and distributed ledger technology, informed by the European Blockchain Sandbox programme. 

The settlement hype problem 

The previous article in this series made the case that distributed ledger technology (DLT) can address a real structural gap in balancing markets: the lack of a shared, tamper-evident audit trail across the parties involved in activation, metering, and settlement. But making that case responsibly means also being honest about what DLT cannot do, and about the gap between industry rhetoric and operational reality. 

The blockchain and energy literature is full of claims about "near-instant settlement" and dramatic cost reductions. Some of these are grounded. Many are not. 

In balancing markets, settlement is not merely a technical process of recording a transaction. It involves metering verification, baseline calculations, performance assessment against contracted parameters, imbalance pricing, and the application of regulatory rules that vary by country and product type. These steps take time not because the underlying technology is slow, but because the market design requires them. No ledger, distributed or otherwise, eliminates the need for metering validation or regulatory compliance checks. 

What DLT can do is compress the time between data becoming available and that data being verified, shared, and acted upon. If all parties have access to the same cryptographic commitments as events occur, the reconciliation step that currently adds days or weeks to the process can be significantly shortened. Settlement logic can run against shared, pre-verified inputs rather than against separately compiled records that need to be cross-referenced first. 

The honest framing is not "instant settlement" but faster, more transparent settlement with a stronger evidence base. In markets where final settlement currently stretches over weeks and correction windows extend months further, even a meaningful reduction in that timeline creates real value: improved cash flow for smaller participants, reduced counterparty risk, and lower administrative costs across the board. 

Staged adoption, not big-bang migration 

One of the practical lessons from the European Blockchain Sandbox dialogues is that successful DLT adoption in regulated sectors tends to be incremental. This is especially true in energy, where infrastructure is classified as critical and the regulatory requirements are extensive. 

A pragmatic path for DLT in balancing settlement might follow three stages. 

Stage 1: Audit and evidence layer. DLT is introduced alongside existing processes, not as a replacement. Cryptographic commitments to bids, dispatch events, and settlement artefacts are recorded on a permissioned ledger. Settlement itself continues through existing banking rails and regulatory mechanisms. The ledger serves as a shared audit trail that can be referenced in disputes, regulatory reviews, or compliance reporting. This stage delivers value without touching payment flows. 

Stage 2: On-ledger accounting. As confidence in the shared record grows, the ledger takes on a more active role in settlement calculation. Obligations and revenue splits are computed using on-chain logic referencing verified off-chain data, providing a transparent, near-real-time view of financial positions. Actual payments still flow through traditional rails, but the accounting layer acts as a single source of truth for what is owed to whom. 

Stage 3: Programmable settlement rails. Subject to regulatory authorisation, settlement could eventually move to token-based or e-money payment rails, enabling automated, programmable disbursement tied to verified delivery. This stage carries its own regulatory implications under MiCA and national e-money frameworks, and it is not required for the earlier stages to deliver meaningful value. 

This approach respects the operational reality of energy markets. It does not require TSOs, DSOs, or aggregators to abandon existing systems. It layers shared evidence and accounting infrastructure on top of what already exists, generating value at each stage while keeping the path to deeper integration open. 

The regulatory tailwind 

The regulatory environment in Europe is moving in a direction that makes DLT-based auditability more relevant, not less. 

The EBS 3rd Cohort Best Practices Report identifies several developments that matter here. The draft Network Code on Demand Response, expected to be finalised in 2026, will introduce more detailed data sharing requirements between aggregators, BSPs, TSOs, and DSOs. The Network Code on Cybersecurity for electricity establishes cybersecurity standards for cross-border electricity flows, complementing NIS2 at the operational level. The Data Act introduces horizontal data sharing rules that interact with existing sector-specific energy regulations. 

Each of these frameworks increases the burden of proof on market participants. Was a dispatch instruction correctly transmitted and acted upon? Can the settlement output be independently verified? Who accessed what data, when, and under what authority? A well-designed DLT layer can answer these questions more efficiently than the current fragmented approach. 

The EBS programme also flagged an important gap: there is currently limited regulatory specificity around how DLT-based audit trails should be evaluated or certified in critical energy applications. The Cybersecurity Act certification framework and potential future schemes under the CSA may eventually provide standardised assessment criteria. But for now, the space is being shaped by organisations that engage constructively with regulators rather than waiting for prescriptive rules to arrive. 

Defining terms clearly 

If DLT is to gain traction as infrastructure for energy markets, the sector needs to be disciplined about language. Too much of the current discourse mixes aspiration with operational reality. A few definitions worth anchoring: 

On-chain commitment: a cryptographic hash of an event or data artefact, written to a shared ledger with a digital signature and timestamp. It proves that a specific piece of data existed at a specific time, without revealing the data itself. 

Off-chain data: the underlying operational data (telemetry, metering, personal information, commercial terms) that remains in the systems of the originating party, with access governed by role-based policies. 

Non-repudiation: the property that a party cannot credibly deny having committed a specific record, achieved through digital signatures rather than through the ledger's consensus mechanism alone. 

Permissioned ledger: a DLT network where participation is restricted to known, authorised parties. This is the appropriate model for critical infrastructure, distinct from public, permissionless blockchains. 

End-to-end auditability: the ability to trace the lifecycle of a balancing event, from bid to activation to metering to settlement, through a linked chain of cryptographic commitments, without relying on any single party's records as the sole source of truth. 

Getting this language right matters. When industry participants and regulators share a precise vocabulary, productive conversations about where DLT adds value, where it doesn't, and what the residual risks are become much easier to have.
