Seguro Promulgates the 5 June Electricity Decree-Law — DL 15/2022 Amendment Transposes EU Directive 2024/1711, Carves Out ZAER Renewable Zones, Exempts 800 W Self-Consumption and Mandates Fixed-Price Tariffs Above 200,000 Customers

President António José Seguro on Friday 5 June 2026 promulgated the Government's decree-law that amends Decreto-Lei n.º 15/2022 of 14 January (Decree-Law No. 15/2022, the law that establishes the organisation and functioning of the Sistema Elétrico Nacional — National Electrical System), transposing Diretiva (UE) 2024/1711 (EU Directive 2024/1711 on electricity-market design) and partially transposing Diretiva (UE) 2023/2413 (the recast Renewable Energy Directive, RED III) and Diretiva (UE) 2023/1791 (the recast Energy Efficiency Directive). The diploma was approved by the Conselho de Ministros (Council of Ministers) on 19 March 2026, sent to Belém for promulgation, and now moves to publication in Diário da República (Official Gazette).

The decree-law's load-bearing innovation is the creation of Zonas de Aceleração da Implantação de Energia Renovável (ZAER — Renewable Energy Acceleration Zones), the Portuguese transposition of the RED III "renewables go-to areas" concept. Projects sited inside a ZAER perimeter benefit from shorter and simplified licensing procedures, with environmental-impact-assessment screening front-loaded at the territorial-mapping stage rather than at the project-by-project stage. The Government's energy ministry frames the ZAER map as the operational vehicle for the Plano Nacional Energia e Clima 2030 (PNEC 2030, the National Energy and Climate Plan) renewable-electricity ramp.

On the consumer-protection side, the diploma carves out three structural changes that will move on day one of publication:

• Self-consumption up to 800 watts is exempt from prior verification. The previous threshold sat at 700 watts under Decreto-Lei n.º 99/2024 — the 100-watt lift catches the standard plug-in microinverter "balcony solar" kits (typically two 400 W modules) sold across European DIY retail, bringing them inside the no-paperwork lane. Surplus injection into the grid still falls outside the exemption.
• Retailers with more than 200,000 customers must offer fixed-price contracts with a minimum duration of one year. The measure ports the Directive 2024/1711 requirement on price-volatility protection for residential consumers — EDP Comercial, Galp Power, Endesa, Iberdrola and Goldenergy all sit above the 200,000-customer threshold and will need to publish a fixed-tariff product, alongside their existing variable and indexed offers, on the day the diploma takes effect.
• The "superior public interest" mechanism for renewables hardens into statutory text. Projects classified under the mechanism can override conflicting territorial-planning or environmental rules where the Government documents an overriding renewable-deployment imperative, mirroring the Directive 2024/1711 framing.

The renewables-acceleration architecture pairs with the energy-crisis framework that the Conselho de Ministros approved at the same 19 March 2026 sitting, which gave Lisbon the toolkit to declare a national or regional energy crisis, impose price-control measures and ask consumers to cut consumption in coordinated steps. Both files now sit inside the broader transposition window for Directive 2024/1711, which Member States must complete by January 2027 under Article 7 of the directive.

The political read on the promulgation is that Seguro cleared the diploma without flagging any of the constitutional-review levers he has used on other decree-laws this spring — no fiscalização preventiva (preventive constitutionality review) referral to the Tribunal Constitucional, no veto note. The signing closes a two-month executive-legislative loop that opened with the Council of Ministers approval and moved through Assembleia da República transmission without contestation.

What This Means for Expats

• Balcony solar enters the no-paperwork lane: If you live in an apartment with balcony or rooftop access and a south-facing exposure, the 800 W self-consumption threshold means you can install a two-panel plug-in microinverter kit without the prior-communication paperwork on the DGEG self-consumption portal, provided you don't inject surplus into the grid. The kits retail for €350–€800 depending on panel quality and inverter brand. Verify the no-grid-injection condition with the equipment installer before signing.
• Fixed-price electricity contracts return to the menu: Households burned by the 2022–2023 spot-price volatility now get a regulated 12-month fixed-tariff option from any retailer above 200,000 customers. The fixed product will sit above the indexed/variable products on price, but the volatility protection is real for households with tight monthly cash-flow.
• Property buyers in rural and Alentejo locations should track the ZAER perimeters: A ZAER classification fast-tracks renewables licensing in the host territory and will reshape rural land-use patterns over the next decade. If you are buying agricultural or rural property, ask the seller and the local câmara whether the parcel sits inside a designated ZAER or a pending designation — the answer can affect both the development upside and the visual-amenity downside.
• Self-consumption tax framing unchanged: The diploma does not touch the IRS, IVA or IRC treatment of self-consumption — the energy-tax frame remains as set by the broader IES (Imposto Especial de Consumo sobre Eletricidade) and IVA framework. Consult a tax adviser before integrating self-consumption into a broader property-investment structure.
• Energy retailer-switching mechanics simplify: Directive 2024/1711's consumer-protection package, partially transposed by this diploma, tightens the retailer-switching window. Households moving residences within Portugal will see retailer-switching timelines compress further, reinforcing the existing 21-day SU-Eletricidade switch window managed by E-REDES.

The promulgation lands the same week that the Lisbon-Setúbal Port pencilled a €1 billion 2025–2035 decarbonisation envelope at the second CPLP Climate Congress, that the Pordata Environmental Portrait ranked Portugal among the four EU member states where more than 95% of energy produced came from renewable sources, and that the Fundo Ambiental moved its Floresta Azul programme into its 2026 disbursement phase. The three files frame the same trajectory: Portugal's electricity-supply side is structurally clean, the renewables pipeline now gets a procedural-licensing accelerator, and the country is positioning to harvest the Directive 2024/1711 consumer-protection toolkit while the Brussels transposition window is still open.
