Serbia’s renewable generators are increasingly exposed to hourly electricity prices and the risk that output is sold during lower-value hours, while industrial users still face expensive evening periods. SEEPEX recorded the country’s first negative day-ahead power price in May 2026. Solar-plus-storage arrangements are described as a way to move some renewable output toward factory demand and hours when grid electricity costs more.
Nocaj project combines solar capacity with 72 MWh storage
The Nocaj project is presented as an example of that approach, with 270 MWp of solar capacity and 72 MWh of storage. The battery is described as not large enough to make the solar plant fully firm. It can improve output shaping and reduce imbalance under a bilateral supply arrangement.
The same project description links those functions to making renewable electricity more usable and predictable for industrial customers. The battery’s role is framed around timing and operational alignment rather than changing the underlying emissions rules. The project’s output is also positioned within an electricity evidence context for carbon reporting.
CBAM starts in 2026 and affects covered exporters’ carbon cost relevance
The European Union’s definitive Carbon Border Adjustment Mechanism (CBAM) period began in 2026. The start of the period increases the relevance of carbon costs for covered exporters. Serbian steel, aluminium and cement producers are identified as sectors that may benefit commercially from cleaner, more manageable electricity procurement.
Storage is described as able to align renewable supply with factory consumption and reduce purchases from the high-carbon grid in selected hours. It is also stated that storage does not itself reduce embedded emissions or provide a CBAM exemption. For exporters, the potential business case includes less exposure to volatile market purchases and better use of renewable output.
CBAM reporting depends on methodology and documented electricity evidence
The compliance relevance of storage is described as depending on the applicable CBAM methodology and the evidence chain rather than battery ownership or capacity alone. Metering, contractual allocation, guarantees of origin where relevant, and verifiable electricity consumption records are identified as necessary elements for supporting claims about electricity use.
The same requirements are described as determining whether output from the Nocaj project can support a particular CBAM electricity claim. Storage is also described as strengthening energy management without replacing the underlying emissions rules. Its value for CBAM reporting is therefore tied to documented electricity evidence and the applicable methodology, including when it improves the timing of renewable supply.
