Battery storage can improve the economics and Carbon Border Adjustment Mechanism (CBAM) readiness of renewable-energy projects in Serbia by making low-carbon electricity more usable and predictable for exporters. It can better align renewable supply with factory consumption and reduce reliance on high-carbon grid purchases during selected hours. However, storage does not itself reduce embedded emissions or provide a CBAM exemption.
The EU’s definitive CBAM period began in 2026, increasing the relevance of carbon costs for covered exporters. Steel, aluminium and cement producers may benefit commercially from a cleaner, more manageable electricity procurement profile. Storage can strengthen energy management, but it does not replace the underlying emissions rules.
CBAM claims depend on electricity evidence
The compliance value of storage depends on the applicable CBAM methodology and the evidence chain, not simply on battery ownership. Metering, contractual allocation and guarantees of origin where relevant remain important. Exporters also need reliable data on electricity consumption to support claims about electricity use.
The potential business case combines lower exposure to volatile market purchases, better capture of renewable output and a more controlled electricity evidence package for carbon reporting. A battery can help determine when renewable power is used. It cannot, on its own, establish how electricity will be treated under CBAM.
Serbia’s market signals and the Nocaj project
Renewable generation in Serbia is increasingly exposed to hourly price and capture risk, while industrial users continue to face expensive evening periods. In May 2026, SEEPEX recorded Serbia’s first negative day-ahead electricity price. The event highlighted the changing hourly price environment for both generation and consumption.
Solar-plus-storage can shift some renewable output toward factory demand and hours when grid electricity is more expensive. The Nocaj project is cited as an example of this market direction and combines 270 MWp of solar capacity with 72 MWh of storage.
The Nocaj battery is not large enough to make the solar plant fully firm, but it can improve output shaping and reduce imbalance in a bilateral supply arrangement. Its relevance to CBAM would still depend on the applicable methodology and documented electricity evidence. Storage capacity alone would not determine that treatment.
