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, illustrating the changing price environment for both generation and consumption. Solar-plus-storage can move some renewable output toward factory demand and hours when grid electricity costs more.
The Nocaj project illustrates that approach, with 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 under a bilateral supply arrangement. Those functions could make renewable electricity more usable and predictable for industrial customers.
CBAM relevance for industrial electricity procurement
The European Union’s definitive Carbon Border Adjustment Mechanism (CBAM) period began in 2026, increasing the relevance of carbon costs for covered exporters. Serbian steel, aluminium and cement producers may benefit commercially from cleaner, more manageable electricity procurement. Storage can help align renewable supply with factory consumption and reduce purchases from the high-carbon grid in selected hours, but it does not itself reduce embedded emissions or provide a CBAM exemption.
For exporters, the potential business case also includes less exposure to volatile market purchases and better use of renewable output. A battery can help control when renewable power is consumed and support a more orderly electricity evidence package for carbon reporting. It cannot, on its own, determine how that electricity is treated under CBAM.
Documentation determines the value of storage for reporting
The compliance relevance of storage depends 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 remain necessary to support claims about electricity use. The same requirements determine whether the Nocaj project’s output can support a particular CBAM electricity claim.
Storage can strengthen energy management without replacing the underlying emissions rules. Its value for CBAM reporting therefore rests on documented electricity evidence and the applicable methodology, even where it improves the timing of renewable supply.
