Formidable Framework & Fiscal Fencing of CBAM Formation

The Carbon Border Adjustment Mechanism, unveiled in May 2021 by the European Commission, seeks to equalise carbon costs between EU producers & foreign competitors. This policy is poised to impose a carbon price on imports of goods with high CO₂ emissions such as iron, steel, cement, aluminium, hydrogen, fertilisers, & notably, electricity. By levelling the playing field, CBAM aims to dissuade carbon leakage, where industries relocate production to countries with looser climate policies. However, while its ambition is commendable, its application to electricity imports, particularly those managed by TSOs, raises complex operational & legal dilemmas.

Transmission Trials & Technical Trade-Offs in TSO Territory

ENTSO‑E, comprising 39 TSOs from 35 nations, plays a crucial role in maintaining the continent’s electricity balance. Unlike energy traders, TSOs operate within strict regulatory frameworks & perform systemic functions such as reserve sharing, congestion management, & redispatch. These activities often necessitate electricity flows across borders, especially from non‑EU countries that are synchronised with the EU grid, like Switzerland, the Western Balkans, & parts of Eastern Europe. ENTSO‑E argues that subjecting these regulated, non-commercial exchanges to CBAM reporting obligations is unjustified, overly bureaucratic, & potentially disruptive to grid stability.

Opaque Operations & Obfuscated Obligations in Emission Evaluation

One of the most pressing issues highlighted by ENTSO‑E is the nebulous methodology for quantifying the embedded CO₂ in imported electricity. Unlike manufactured goods with traceable supply chains, electricity is fungible & flows across interconnected grids. Determining the exact carbon content of an imported megawatt-hour from a neighbouring grid is methodologically elusive. Currently, no harmonised emission calculation protocol exists under CBAM for electricity, leaving TSOs to navigate a legal labyrinth with unclear standards, high compliance costs, & elevated risk of regulatory infractions.

Disproportionate Duties & Dubious Demands on Neutral Networkers

ENTSO‑E insists that TSOs should be categorically exempted from CBAM obligations. TSOs are neutral, regulated entities, not commercial importers or exporters. Their purpose is to ensure secure, efficient, & reliable electricity supply across Europe. The group underscores that the emissions associated with their operations are incidental, not intentional, & that imposing CBAM duties on such flows would be a misapplication of the law. Furthermore, such a move could discourage regional cooperation in grid balancing, counteracting broader EU goals of interconnected, decarbonised energy systems.

Precautionary Proposals & Pre-Implementation Probing Essential

To preempt implementation pitfalls, ENTSO‑E advocates for an additional, dedicated impact assessment before the definitive CBAM application to electricity begins on 1 January 2026. This evaluation should explore the practical implications of including regulated flows, quantify the real risk of carbon leakage from TSO operations, & propose clear exemptions or modifications. Without this data-driven inquiry, CBAM risks becoming a blunt instrument that penalises essential public service entities while missing its true targets, commercial emitters exploiting regulatory loopholes.

Geopolitical Gridlocks & Geographic Gradations in Third-Country Grouping

Another cornerstone of ENTSO‑E’s position is its call for a more refined approach to listing exempted third countries. Several non‑EU nations maintain strong operational ties with the EU grid, participate in balancing mechanisms, & sometimes match EU standards on renewable energy sourcing. Yet CBAM, in its current formulation, risks classifying all non‑EU electricity as equally carbon-intensive. ENTSO‑E encourages the Commission to differentiate countries not only based on their national emission profiles but also their technical integration, environmental alignment, & system reliability contributions.

Collaborative Channels & Constructive Consultations Crucial for Coherence

ENTSO‑E concludes its paper by offering to collaborate directly with the European Commission, industry stakeholders, & environmental experts. It calls for an inclusive, transparent dialogue to recalibrate CBAM's application to the electricity sector. Through expert-led discussions, legally coherent exemptions, & scientifically grounded emission measurements, the EU can design a policy that protects its climate objectives without compromising the operational stability of its grid. ENTSO‑E remains committed to supporting this legislative evolution with empirical insights & policy pragmatism.

Key Takeaways

• ENTSO‑E requests exemption for TSOs from CBAM due to their non-commercial, regulatory roles.

• A harmonised method to measure imported electricity's CO₂ content is urgently needed.

• The Commission is urged to reassess third-country groupings & conduct impact assessments before 2026.
