Serbian manufacturers need to connect renewable electricity supply, factory consumption and finished products to substantiate low-carbon claims for exports. Annual procurement totals alone are insufficient where evidence must demonstrate how electricity entered production and whether it qualifies under the applicable EU Carbon Border Adjustment Mechanism (CBAM) methodology.
Electricity Data and Contracts Must Support Claims
Factories should reconcile grid imports, on-site generation, battery charging and discharge, exports, process consumption and losses within defined tolerances. Under the current CBAM methodology for actual indirect electricity emissions, qualifying arrangements can require generation and consumption to be matched within periods of one hour or less. Fifteen-minute intervals may be useful operationally, but are not a universal legal requirement.
Renewable certificates alone do not establish eligibility. Where manufacturers rely on a qualifying physical power purchase agreement (PPA), the contract, grid connection and delivery structure must support the claim. Relevant evidence may include generator identity, meter records, settlement data and verified emissions reports.
Production Allocation and Storage Controls
Manufacturers with multiple production lines can allocate electricity using line meters, machine hours, throughput or another documented engineering method. Calculations must reconcile with total site consumption and prevent products from being assigned more electricity than the factory actually used.
On-site solar and batteries require separate accounting. Solar generation should be divided between self-consumption and exports, while battery records should identify charging sources, timing, losses and discharge. Storage shifts electricity across time but does not independently create renewable attributes.
Product reports should distinguish electricity physically consumed, electricity supported by renewable attributes and electricity eligible under the relevant emissions methodology. These quantities may differ and should be reported transparently.
Monthly Statements Strengthen Verification
A monthly electricity qualification statement can reconcile factory consumption, on-site generation, contracted renewable delivery, renewable attributes and quantities accepted under each reporting method. It should also record generator outages, meter corrections and substitute supply.
Manufacturers should stress-test allocation models against shutdowns, low-production periods and heavy battery use. Customer reports must identify the period covered by each claim; electricity contracted later cannot automatically be assigned to earlier production unless the selected methodology permits it.
Reliable records help EU buyers verify product claims, banks assess renewable investments and procurement teams compare suppliers on electricity costs and data quality. For Serbian exporters, reconciling physical flows, contracts, timing and production allocation provides the evidence linking renewable electricity purchases to exported goods.
