Battery storage can make renewable electricity more usable and predictable for Serbian exporters, improving the economics and CBAM readiness of renewable-energy projects. The definitive period of the Carbon Border Adjustment Mechanism (CBAM) began in 2026, increasing the relevance of carbon costs for covered exporters. Storage does not itself reduce embedded emissions or create a CBAM exemption.
CBAM-covered exporters in steel, aluminium and cement may benefit commercially from a cleaner, more manageable electricity procurement profile. Storage can align renewable electricity use with predictable consumption patterns and reduce reliance on high-carbon grid purchases during selected hours. It strengthens energy management for CBAM readiness, but does not replace the underlying emissions rules.
Electricity markets and evidence
Serbia’s renewable generation is becoming more exposed to hourly price and capture risk, while industrial users continue to face expensive evening periods. SEEPEX recorded Serbia’s first negative day-ahead electricity price in May 2026. Solar-plus-storage can shift some renewable output to factory consumption hours, when grid electricity is more expensive.
The strongest business case combines lower exposure to volatile market purchases, better capture of renewable output and a more controlled electricity evidence package for carbon reporting. Storage’s compliance value depends on the applicable CBAM methodology and evidence chain, not simply on owning a battery.
Metering and contractual allocation remain essential, alongside guarantees of origin where relevant and verifiable consumption data. Those records support the evidence chain for electricity use; storage alone does not establish how electricity is treated under CBAM.
Nocaj project illustrates storage’s role
The Nocaj solar-storage project, cited as an example of the market’s direction, has 270 MWp of solar capacity and 72 MWh of storage. Its 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.
Solar-plus-storage can help make low-carbon electricity more predictable for exporters, but the CBAM compliance value still depends on the applicable methodology and verifiable evidence. Storage can strengthen the energy-management side of CBAM readiness; it does not replace CBAM’s emissions rules.
