CBAM timeline and the role of electricity procurement
The EU’s definitive Carbon Border Adjustment Mechanism (CBAM) period began in 2026, raising the relevance of carbon costs for covered exporters. In that context, steel, aluminium and cement producers may benefit commercially from a cleaner and more manageable electricity procurement profile. Storage is described as not reducing embedded emissions by itself and it does not create a CBAM exemption. The Nocaj solar-storage setup is presented as an example of how storage can make renewable electricity more usable and predictable for exporters.
Nocaj solar-storage configuration and factory load shifting
Serbia’s Nocaj project pairs a 270 MWp solar plant with 72 MWh of battery storage. The storage is stated to help shift some solar output toward factory consumption periods. The battery size is also described as insufficient to make the solar plant fully firm. Instead, it is positioned as a tool for improving output shaping and reducing imbalance in a bilateral supply arrangement.
Why batteries do not replace CBAM compliance evidence
Owning a battery alone is not presented as establishing the compliance value of electricity under CBAM. The compliance value depends on the applicable CBAM methodology and the evidence chain used to support electricity claims. Metering, contractual allocation, guarantees of origin where relevant, and verifiable consumption data are identified as essential elements. Storage can support exporters in aligning renewable electricity use with predictable consumption patterns and in reducing reliance on high-carbon grid purchases during selected hours.
Hourly price exposure and day-ahead market signals
Serbian renewable generation is described as increasingly exposed to hourly price and capture risk. Industrial users are also said to continue facing expensive evening periods. SEEPEX recorded Serbia’s first negative day-ahead electricity price in May 2026. In this setting, solar-plus-storage can shift some renewable output toward factory demand and toward hours when grid electricity is more expensive.
CBAM relevance tied to documented use rather than capacity
At Nocaj, the 72 MWh battery is characterized as improving output shaping rather than fully firming the solar generation. The CBAM relevance of the arrangement is stated to depend on documented electricity use and the applicable methodology. Storage is also described as not replacing underlying emissions rules or the evidence requirements needed for CBAM readiness. The emphasis remains on how electricity claims are supported through metering and allocation rather than on storage capacity alone.
