The Bulgarian energy landscape has faced a significant regulatory shift following the Supreme Administrative Court’s decision to annul an environmental exemption for the TPP Maritsa East 2 coal-fired power plant. This ruling marks a pivotal moment in the ongoing struggle between environmental advocacy and industrial operations, particularly as it pertains to compliance with European Union pollution standards.
The court’s decision stems from a protracted legal battle initiated by environmental organizations, notably Greenpeace Bulgaria and For the Earth. These groups have long argued that the exemption allowed TPP Maritsa East 2 to emit pollutants at levels significantly exceeding EU limits, a situation activists hailed as one of the most consequential environmental victories in recent Bulgarian history.
Central to the court’s ruling was the assessment of a derogation that had permitted the plant to bypass established EU environmental standards concerning sulfur dioxide emissions. Prior assessments indicated that TPP Maritsa East 2 was allowed to release sulfur dioxide at nearly double the legal limit and mercury at more than four times the permitted level, raising serious concerns about public health and environmental integrity.
The Supreme Administrative Court upheld an earlier judgment from the Administrative Court in Stara Zagora, which had previously overturned a 2018 amendment made by Bulgaria’s Executive Environment Agency regarding the plant’s integrated operating permit. The judges found that Bulgarian authorities had inadequately evaluated the cumulative environmental and health impacts associated with these emissions, highlighting a failure to consider critical scientific evidence and local air quality regulations in Galabovo.
This ruling also emphasized non-compliance with European environmental law requirements, specifically those governing derogations, referencing a related case adjudicated by the Court of Justice of the European Union (CJEU), case C-375/21. The implications of this ruling extend beyond TPP Maritsa East 2, potentially influencing future regulatory approaches for other facilities operating under similar exemptions.
The legal proceedings surrounding this case have evolved through multiple stages over recent years. Earlier in 2023, the Supreme Administrative Court had already annulled a lower court ruling due to procedural discrepancies, mandating that the case be re-evaluated by a different judicial panel. This ongoing scrutiny reflects a broader trend within Bulgaria and across Europe towards stricter enforcement of environmental regulations in the energy sector.
