Brussels Refers Portugal to the Court of Justice for Failing to Transpose the RED III Renewables Directive — Lisbon Joins Athens and Valletta on the Defendants' Bench Almost a Year Past the 21 May 2025 Deadline

The European Commission has referred Portugal to the Court of Justice of the European Union over Lisbon's failure to transpose Directive (EU) 2023/2413 — the so-called RED III revision of the Renewable Energy Directive — into Portuguese national law. The referral was announced from Brussels on Wednesday 29 April 2026 and surfaced into the Saturday news cycle through Lusa wire reporting carried by Público's Azul environment desk. Greece and Malta were referred on the same Wednesday docket and now sit alongside Portugal as co-defendants in what is the largest single-Wednesday Article-258 TFEU package the Commission has filed on a single energy directive since the RED II transposition wave.

The legal posture is straightforward. Member States were obliged to bring into force the laws, regulations and administrative provisions necessary to comply with RED III by 21 May 2025. More than eleven months past that deadline, Portugal has notified Brussels of no national measures that would integrate the directive into the Portuguese legal order. The Commission's standard infringement-procedure choreography ran to script through the second half of 2025 — Letter of Formal Notice in July 2025, Reasoned Opinion in December 2025 — before Wednesday's CJEU referral closed out the pre-litigation phase and opened the contentious one.

What RED III actually requires

RED III rewrites RED II to lift the binding 2030 EU-wide renewable-energy share from 32% to a minimum 42.5%, with a non-binding 45% aspirational ceiling that the Commission is using as the working planning anchor for the Fit-for-55 trajectory. The directive accelerates the permit-granting timetables for renewable-electricity projects (90 days inside renewable-acceleration areas, 12 months inside ordinary network areas), introduces sub-targets for renewable hydrogen in industry (RFNBO take-up of 42% by 2030 and 60% by 2035) and obliges Member States to set a 29% renewable share in transport-energy consumption by 2030 — covering road transport, rail and the aviation/maritime perimeter that the ReFuelEU and FuelEU regulations carve in parallel.

For the buildings track, RED III asks Member States to set an indicative renewable-share target for the building stock by 2030 of at least 49%, layered on top of the EPBD recast's renovation-passport regime. For the industry track, it asks for an annual indicative increase in renewable-energy use of 1.6 percentage points averaged over the 2021-2025 and 2026-2030 windows. None of those sub-targets attaches to a directly enforceable financial penalty under the directive itself — the penalty exposure runs through the infringement-procedure track that Wednesday opened.

The procedural step Wednesday cleared

The Commission's referral file asks the Court to declare that Portugal has failed to fulfil its obligations under Article 39 of RED III (the transposition deadline article) and to impose financial sanctions in line with the Commission's January 2023 communication on financial penalties under Article 260(3) TFEU. Penalties under Article 260(3) — the fast-track route the Commission can request for non-transposition — combine a lump-sum component covering the period since the transposition deadline and a daily penalty payment running from the Court's eventual judgment until full transposition is verified. The lump-sum minimum for Portugal under the January 2023 schedule sits in the low-hundreds-of-thousands-of-euros range; the daily penalty for protracted non-compliance can run into the low six-figure euros per day.

The Wednesday docket also carried a separate, second Reasoned Opinion against Portugal on the parallel electricity-market-design package — the Commission's autumn 2024 reform of the consumer-protection wrapper around variable-rate electricity contracts (contract-switching freedom, supply-interruption safeguards, dynamic-pricing hedging access). Portugal has two months from receipt of the Reasoned Opinion to notify Brussels of full transposition; if it misses that window, a second CJEU referral on the electricity-market track follows automatically.

Where Portugal sits domestically

Lisbon's transposition file has been bottlenecked at the Direção-Geral de Energia e Geologia and the Ministério do Ambiente through 2025 and into 2026, with the underlying delay tied to the renewables-licensing reform that the PRR Commissão Nacional de Acompanhamento has now flagged twice as a critical-state reform — including in the €1.5 billion at-risk warning the Commission's chair Álvaro Dominguinhos delivered to Parliament's Committee on Public Works on 30 April. The renewables-licensing reform is one of the four PRR-conditional reforms that has to clear the Assembleia da República before the mid-July parliamentary recess for the late-2026 PRR disbursement tranche to land on schedule; the reform has been split into a renewables-acceleration-areas decree and a sites-of-strategic-interest framework, neither of which has cleared committee yet.

The DGEG's own renewable-share running estimate for end-2024 sat at roughly 36% of gross final energy consumption — well above the EU average and inside the Top-5 Member-State band, but materially below the 42.5% RED III mandates for end-2030. The PNEC2030 (Plano Nacional de Energia e Clima 2030) targets a 51% renewable share in gross final consumption by 2030 — a ceiling that Portuguese policy will not get within striking distance of without the renewables-licensing reform clearing Parliament and the corresponding decree-law package being notified to Brussels by Q3 2026.

The wider Commission docket

Wednesday's three-Member-State referral is the largest single CJEU package the Commission has filed on a single energy directive since spring 2024, when six Member States were referred on RED II implementation gaps. Greece and Malta sit alongside Portugal on the RED III file; the Commission has also issued additional Letters of Formal Notice in the same week to a further set of Member States that have notified partial-transposition measures but where the Commission considers the notification incomplete. Portugal is not on that LFN list — the Lisbon file is squarely at the no-transposition-at-all end of the spectrum, the worst posture in the procedural matrix.

The Court's docket on Article-258 TFEU non-transposition cases has been running at a 12-to-18-month elapsed time from referral to judgment under the fast-track procedure; a 2027-vintage CJEU judgment against Portugal on the RED III file is now the working planning baseline. Lisbon's option to short-circuit the procedural runway is to notify full transposition before the Court delivers its judgment, in which case the daily-penalty component zeroes out and only the lump-sum component for the elapsed-time-from-deadline period crystallises. That option is on the table for the duration of the Article-260(3) docket and is the standard endgame in non-transposition cases.

Cross-references in the domestic energy file

The RED III referral arrives in a busy domestic-energy week. Decreto-Lei 94/2026 entered into force on 2 May on the biomethane-connection-cost track — a separate but RED-III-relevant file because biomethane qualifying volumes count toward the 2030 renewable-share calculation in the gas system. Saturday's ECO ISP weekly recalibration sits in the same domestic-energy bucket but on the fossil side. The 5 June ECB Governing Council meeting and the 13 June OPEC+ ministerial calibrate the broader fossil/renewable cost-curve against which the RED III transposition policy debate will run through the summer.
