Electricity prices in Southeast Europe remained fragmented in Week 23, with gas-related risk returning alongside changes in generation and renewable output. The week highlighted how power-market conditions can affect industrial exporters exposed to EU carbon rules. Electricity procurement for steel, aluminium, cement, fertiliser, chemicals and other CBAM-exposed sectors is described as a carbon and compliance issue.
The weekly price range was wide across regional markets. Italy averaged €128.09/MWh, Hungary €103.15/MWh, Romania €102.23/MWh, Bulgaria €100.83/MWh, Serbia €99.63/MWh, Croatia €99.29/MWh, Greece €89.25/MWh and Türkiye €22.53/MWh. The divergence affects industrial competitiveness for electricity-intensive producers.
Week 23 generation shifts toward thermal output
Generation patterns in Week 23 moved toward dispatchable conventional production. Thermal generation rose 24.5% week on week, while variable renewable generation fell 8.9%. The changes were accompanied by country-specific moves in fuel use and dispatch.
In Türkiye, gas-fired generation increased by 278.1%. In Greece, lignite output rose by 66.2%. These shifts can affect embedded emissions profiles depending on the electricity basis used for calculations.
CBAM documentation requirements for electricity basis
CBAM increases the importance of credible electricity documentation for exporters selling into the EU. Exporters are expected to understand not only direct emissions, but also the electricity basis used in embedded-emissions calculations where applicable. Annual procurement claims may not be sufficient where buyers, declarants or verifiers require additional evidence.
The evidence expectations include renewable sourcing support, hourly matching and contract credibility. This documentation need is tied to how electricity is characterised within embedded-emissions approaches used by industrial exporters.
Renewable PPAs and storage in procurement strategies
A renewable PPA is positioned as a tool that can reduce price exposure and support decarbonisation claims while improving buyer confidence. For industrial buyers, the structure requires evidence covering generation source, grid connection and metering arrangements. It also includes guarantees of origin or equivalent certificates.
The same procurement framework is linked to balancing responsibility and delivery profile requirements for the buyer’s consumption pattern. Battery-backed renewable procurement is also described as potentially improving the match between renewable generation and industrial demand.
Storage can reduce reliance on fossil-heavy evening power and strengthen the credibility of green electricity claims. For large exporters, battery-backed procurement may be incorporated into a wider CBAM-ready procurement strategy.
Spot market exposure and portfolio approaches
Week 23 is cited as an example of why relying only on the spot market can be risky for industrial buyers. Exposure to volatile day-ahead prices can lead to sudden cost increases when gas prices rise, renewables fall or imports tighten.
A structured procurement portfolio is described as combining PPAs, hedges, guarantees of origin and flexible consumption options. This approach is associated with reducing both price risk and carbon risk under CBAM-related requirements.
EU buyer questions tied to power sourcing and emissions calculations
For SEE exporters, electricity strategy is increasingly treated as part of market access into the EU. Buyers are expected to ask how electricity was sourced and how emissions were calculated for reporting purposes.
The same buyer scrutiny extends to whether low-carbon claims are auditable amid power-market volatility across the region. In this context, electricity procurement is treated as a compliance architecture rather than only a purchasing function.
