Serbia’s electricity system has become a core compliance factor under the European Union’s Carbon Border Adjustment Mechanism (CBAM), with implications extending across industrial production, export certification, and emissions accounting for energy-intensive goods.

The CBAM framework now places Serbian electricity procurement and consumption practices directly within embedded emissions reporting requirements for export-oriented industries, particularly in steel, aluminium, cement, and fertiliser production.
CBAM Scope and Industrial Exposure in Serbia
Serbia’s electricity dimension is treated as a distinct CBAM workstream, covering both electricity as a potential exported product and electricity consumed within domestic manufacturing processes that generate indirect emissions.
Indirect emissions are defined under EU rules as emissions linked to electricity consumed during production. Within CBAM’s current scope, indirect emissions apply to cement, fertilisers, and agglomerated iron ore, while iron and steel, aluminium, and hydrogen remain limited to direct emissions. Serbian steel and aluminium producers are nevertheless expected to develop electricity monitoring systems due to increasing EU buyer requirements.
Industrial Base and Energy System Conditions
Serbia’s industrial exposure is concentrated in steel production in Smederevo, aluminium processing at Impol Seval, cement production by Holcim Serbia, Moravacem, and Titan Kosjerić, and fertiliser operations at Elixir Prahovo.
Energy Community data report 8,981 MW of installed electricity capacity, 34,706 GWh of generation, and 35,725 GWh of gross consumption. The day-ahead market records 5,432 GWh of traded volume, with 44 members, an average baseload price of €102/MWh, and 11 active electricity suppliers. Non-regulated supply accounts for 53.5% of total electricity.
The same dataset indicates a 38.12% renewable share in Serbia’s decarbonisation outlook, while the remaining system exposure is linked to fossil-based generation, making the national grid emission factor a central variable in CBAM calculations.
CBAM Electricity Calculation and Emission Factor Rules
CBAM methodology defines indirect emissions as electricity consumption multiplied by an applicable emission factor. EU guidance allows either a grid emission factor or an actual emission factor, depending on compliance conditions. For Serbia, this distinction determines whether industrial electricity is assigned a national grid intensity or a lower value supported by verified procurement structures such as PPAs or direct connections.
Factories using standard Serbian grid electricity are assigned the national grid factor, while those with verified renewable supply arrangements may qualify for alternative emission factors subject to documentation requirements.
Electricity Procurement Hierarchy and Guarantee of Origin Framework
CBAM-aligned procurement in Serbia follows a structured hierarchy: on-site generation, direct technical connection, corporate power purchase agreements (PPAs), standard green supply contracts, and unbundled Guarantees of Origin (GOs).
The strongest compliance position is achieved through on-site renewable generation, particularly solar installations with dedicated metering, followed by direct connections between generators and industrial users. Corporate PPAs with named Serbian renewable assets require supporting metering, settlement data, and supplier verification.
Serbia’s Guarantee of Origin system, administered by Elektromreža Srbije (EMS), issues certificates representing 1 MWh of renewable electricity. EMS operates the registry under the national renewable energy framework, but GOs function as disclosure instruments and cannot independently establish CBAM emission factors.
Corporate PPA Structure and Contractual Requirements
Amendments to Serbia’s Energy Act introduced in 2024 removed the requirement for renewable generators to hold supply licences for PPAs, while maintaining the obligation for licensed electricity suppliers to act as intermediaries between producers and final customers. This structure creates a three-party model involving the generator, supplier, and industrial buyer. Suppliers are responsible for balancing supply and delivering missing volumes.
CBAM-aligned PPAs must therefore include a dedicated electricity annex covering generator identity, installed capacity, technology type, metering configuration, grid connection points, settlement periods, GO ownership, cancellation procedures, curtailment rules, and audit rights. A replacement-power clause is required to ensure that any under-delivered renewable electricity is reclassified as grid electricity unless substituted with verified alternative low-carbon supply.
Electricity MRV Systems and Accounting Structure
Serbian industrial facilities must implement electricity MRV through dedicated ledgers tracking all energy flows, including grid imports, PPA-backed electricity, on-site generation, direct connections, backup fossil generation, exports, and auxiliary consumption. Each electricity category must be linked to evidence status and emission factors, with reconciliation against EMS and distribution system operator (DSO) metering, supplier invoices, production records, and enterprise resource planning systems.
An illustrative case shows a facility consuming 100,000 MWh annually, of which 60,000 MWh is PPA-backed and 40,000 MWh is grid-based. PPA attribution depends on contractual and metering validation, while remaining volumes default to the Serbian grid emission factor.
In variable generation conditions, such as a PPA delivering only 50,000 MWh, the shortfall must be treated as grid electricity unless covered by verified replacement supply.
Guarantee of Origin System and Residual Mix Reporting
EMS operates the Serbian Guarantee of Origin registry and publishes a National Residual Mix Yearly Report, including adjustments aligned with the European attribute mix. The residual mix is used to prevent double counting of renewable electricity attributes. For CBAM purposes, GO records must include serial numbers, cancellation data, beneficiary identification, production periods, and reconciliation with consumption periods.
GOs remain secondary to metered electricity data and contractual delivery evidence in CBAM compliance structures.
Electricity Market Developments and Negative Pricing
Serbia’s electricity exchange SEEPEX introduced negative pricing in May 2026. On 5 May 2026, the day-ahead market allowed negative prices for delivery from 6 May 2026, with a revised price floor of €0/MWh to –€500/MWh. The intraday market was set with a floor of –€9,999/MWh. The first negative day-ahead clearing occurred on 10 May 2026 for the 14:00–15:00 hour at –€0.01/MWh, followed by intraday negative trades on 24 May. These developments introduce hourly price risk into Serbian industrial PPAs, affecting curtailment rules, storage integration, and allocation of renewable electricity under CBAM-aligned contracts.
Electricity Export Rules and CBAM Border Compliance
Electricity exported into the EU is classified as a CBAM-covered good. The authorised CBAM declarant is typically the importer or indirect customs representative, with supporting documentation required for transmission capacity allocation and nomination.
Default emission values are based on International Energy Agency five-year average CO₂ factors. Actual emission values may be used only if strict conditions are met, including a qualifying PPA or direct connection, absence of transmission congestion, emissions below 550 gCO₂/kWh, and hourly matched generation and capacity nomination.
Market Coupling Conditions and Regulatory Alignment
Energy Community rules link electricity market coupling with CBAM exemptions. Time-limited exemptions may apply where non-EU electricity markets are fully coupled with the EU system and where technical CBAM application is not feasible. From 1 January 2026, contracting parties may only remain or become coupled under approved exemption conditions. Serbia continues to align its electricity market framework with EU rules, but CBAM exposure remains in force until coupling and exemption conditions are fully established.
Electricity Data Structuring for CBAM Compliance
Serbian industrial compliance strategy is increasingly defined by structured electricity datasets rather than contractual green labels.
Required datasets include metered electricity volumes, generation source identification, delivery timing, emission factors, GO cancellation records, supplier confirmations, settlement data, residual mix treatment, and allocation methods linked directly to production outputs. Electricity suppliers are effectively required to provide CBAM-ready evidence packages, while industrial users must ensure full traceability for verification by accredited CBAM auditors.
