ACER flags Romania's delayed energy transition as adequacy risk

ACER published its Opinion on Romania's National Resource Adequacy Assessment, timed to complement the ERAA 2025 edition. The central finding: delayed progress on Romania's energy transition is feeding directly into unreliable adequacy signals, making it harder for national authorities to make sound security-of-supply decisions.

The ERAA methodology requires national assessments to reflect realistic decommissioning and build-out trajectories. Where transition timelines slip (retirements delayed, new capacity additions pushed back), the resulting adequacy picture overstates or understates true resource needs. ACER's opinion flags Romania as a case where that misalignment is now material.

For market participants with exposure to Romania, whether capacity-market positions, cross-border interconnection rights, or bilateral PPAs, the opinion signals that national adequacy parameters may need revision before the next ERAA cycle. No numerical adequacy margin figures were disclosed in the published summary.
