Clarion Engineer has become an OIE Serbia Knowledge Partner, bringing its developed CBAM Verified Electricity Playbook to the renewable energy industry through a dedicated workshop that will form an official addendum to the RES SERBIA 2026 conference programme.
CBAM has already been identified by OIE Serbia as one of the principal themes of this year’s conference. Marcel Duits, President of the International Association for the Carbon Border Adjustment Mechanism — IACBAM — is among the announced speakers, while Clarion Owners Engineers has also been announced in conference communications as the dedicated CBAM partner hosting a specialist side-event during the first day of the conference.
The CBAM Verified Electricity workshop will translate the new EU framework for electricity under the Carbon Border Adjustment Mechanism into practical procedures for renewable electricity producers, suppliers and traders, industrial buyers and other market participants.
The workshop will be based on Clarion Engineer’s already-developed CBAM Verified Electricity Playbook, which provides an operational framework covering the complete electricity evidence chain — from renewable generation and power purchase agreements to metering, electricity supply, industrial consumption, MRV, pre-verification and preparation of evidence for formal verification.
The playbook defines the roles and responsibilities of producers, electricity suppliers and traders, industrial buyers, CBAM teams, technical teams, EU counterparties and verification parties, together with the procedures and evidence exchanges required between them.
Clarion Engineer has also developed a broader suite of tailor-made CBAM operational playbooks for participants across the European value chain. These include dedicated methodologies for EU importers and authorised CBAM declarants, as well as sector-specific playbooks for steel and aluminium exporters to the EU, including the treatment and documentation of relevant precursor materials and embedded-emissions data.
In parallel, Clarion has developed detailed pre-verification procedures designed around the anticipated workflow of EU-accredited verifiers, mapping the likely verification process from evidence preparation and data reconciliation through sampling, traceability checks, corrective actions and final verifier handover. This allows exporters, producers, importers and declarants to prepare their CBAM files in a manner aligned with the way formal verification is expected to be performed.
Particular emphasis in the OIE workshop will be placed on the critical integration points between renewable producers and industrial buyers, including PPAs and electricity supply contracts, metering and SCADA records, settlement data, environmental attributes, electricity consumption records, MRV controls, evidence retention, reconciliation and pre-verification procedures.
The workshop is designed to move the market discussion beyond the general concept of purchasing green electricity towards the practical question of how electricity can be made traceable, MRV-ready and verification-ready for relevant CBAM applications.
Participants will work through the electricity chain from renewable generation to industrial consumption, identifying who is responsible for each dataset, control and document, how information should be transferred between counterparties and where verification risks can arise.
As an official conference addendum, the workshop will complement the wider RES SERBIA 2026 programme by providing a specialised working session for companies directly affected by the emerging interaction between renewable electricity procurement, industrial decarbonisation and CBAM.
Through its Knowledge Partnership with OIE Serbia, Clarion Engineer aims to establish a common practical language between the renewable energy and industrial sectors and help market participants prepare their contractual, technical, MRV and verification processes for the new European carbon-accounting environment.
