Wind power in Portugal supplied just over a quarter of the country's electricity needs during 2025, but the sector is stalling at a critical juncture—and that stagnation could jeopardize ambitious national climate commitments and redirect billions in renewable investment to faster-moving neighbors like Spain.
Why This Matters
• Stagnation risk: Despite reaching 25.4% of electricity consumption, new wind capacity in Portugal flatlined in 2025, falling short of the trajectory needed to hit 2030 targets.
• Licensing logjam: Years-long waits for environmental approvals, outdated grid infrastructure, and unclear timelines are choking new projects.
• Offshore delays: The first public auction for 2 GW of offshore wind—initially planned for 2023—remains postponed, threatening to divert international capital elsewhere.
• Hybrid pivot: Developers are increasingly pairing wind with solar and battery storage to boost profitability as midday solar gluts crater electricity prices.
Falling Short of National Targets
Portugal's onshore and offshore wind fleet generated 13.5 terawatt-hours (TWh) in 2025, covering one-quarter of the 53.1 TWh consumed on the mainland, according to a joint report released by the Institute for Science and Innovation in Mechanical and Industrial Engineering (INEGI) and the Portuguese Renewable Energy Association (APREN). While that share marks wind as the country's second-largest electricity source, the addition of new capacity has ground to a near-halt.
The National Energy and Climate Plan (PNEC 2030), revised and approved in 2024, calls for 10.4 gigawatts (GW) of onshore wind and 2 GW of offshore turbines to be operational by the end of the decade—figures the INEGI–APREN study labels "highly ambitious and demanding." Achieving them will require "close collaboration between public and private actors," the authors warn, to accelerate project timelines that have slowed to a crawl.
Susana Serôdio, policy and market intelligence coordinator at APREN, told the Portuguese news agency Lusa that the sector has experienced "effective stagnation" in recent years. "Wind has not kept pace with what would be expected under PNEC 2030," she said. The chief culprits: licensing delays, lack of visibility on approval schedules, bottlenecks in environmental impact assessments, adverse market conditions, and insufficient grid capacity.
Construction Pipeline Leans on Retrofits and Hybrids
As of early 2025, just 446.8 megawatts (MW) of wind capacity was under construction in Portugal, with roughly 80% attributed to new projects—including the Tâmega Norte park at 194.4 MW and Tâmega Sul at 79.2 MW. In May, Iberdrola began energizing Tâmega Norte, the first hybrid wind-hydroelectric complex connected to the grid in the Iberian Peninsula.
Yet the majority of new developments are hybridizations—projects that combine wind with existing hydro or solar installations to share grid connection points and avoid lengthy queue times for new substations. In March, Hyperion Renewables, in partnership with Vestas and Windpark, broke ground on the Nortada wind farm in central Alentejo, a hybrid complex pairing wind, solar, and battery storage for a combined 31.5 MW. The facility is slated to enter service by mid-2027.
Repowering—swapping aging turbines for more efficient models—accounts for 14% of capacity under construction, while overequipment (installing more generation than the grid injection limit allows) makes up the remaining 6%. The imperative to retrofit is stark: by 2026, 88% of Portugal's wind parks will be 15 years old or more; by 2029, that figure climbs to 95%, representing roughly 5.2 GW of installed power.
What This Means for Residents and Investors
For households and businesses in Portugal, the wind sector's plateau has several practical consequences:
• Price volatility: Slower renewable buildout means continued reliance on imported gas and spot-market electricity, leaving consumers exposed to price swings—especially during summer when wind output typically dips.
• Grid strain: The country's transmission network is "completely undersized and outdated," according to industry assessments. Until upgrades accelerate, intermittent blackouts or curtailment of renewable output remain possible in high-production periods.
• Job creation lag: Each gigawatt of new wind capacity typically supports hundreds of construction and maintenance jobs. The stall translates to foregone employment, particularly in the inland districts of Viseu, Coimbra, Vila Real, and Guarda, which host the bulk of Portugal's 6 GW of installed wind capacity.
• Rental and land income: Communities and landowners in wind-rich areas—everywhere except Évora, the sole mainland district without a single turbine—stand to lose lease revenue if projects move abroad.
For international developers eyeing the Portuguese market, the message is unambiguous: bureaucratic friction and financing uncertainty are steering capital toward Spain, where offshore auctions have advanced more rapidly, and toward emerging Atlantic markets in Ireland and Scotland.
The Offshore Gamble: 2 GW by 2030 or Bust?
Portugal's most audacious bet lies at sea. The Offshore Renewable Energy Allocation Plan (PAER), approved by the Council of Ministers in February 2025, designates marine zones off Viana do Castelo (0.8 GW), Leixões (2.5 GW), Figueira da Foz (4.6 GW), and Sines (1.5 GW) for commercial-scale floating wind farms, totaling up to 9.4 GW of potential capacity.
Yet the first competitive tender—originally penciled in for 2023—has been pushed back repeatedly. In April, environmental groups and APREN voiced alarm that no auction rules had been published, despite a 60-day deadline set by ministerial dispatch 4752/2025 in April 2025. Even if the process launches immediately, APREN estimates first offshore platforms will not come online until 2031 or 2032, well past the PNEC deadline.
The sole operational offshore asset today is WindFloat Atlantic, a pioneering 30 MW floating array off Viana do Castelo commissioned in 2020. In January 2025, Tokyo Gas acquired a 21.2% stake in the project, signaling continued foreign appetite—provided Lisbon can deliver a stable regulatory framework. Meanwhile, IberBlue Wind has proposed "Botafogo," a 990 MW floating park near Figueira da Foz featuring 55 turbines of 18 MW each, capable of powering hundreds of thousands of homes.
Hybrid Economics: Pairing Wind with Solar to Beat the Midday Slump
The rise of hybridization reflects a hard economic reality: as solar installations proliferate, midday electricity prices in Portugal have collapsed, eroding returns on photovoltaic-only projects. "At the hour of solar production, prices are very low and profitability becomes very small," Serôdio explained. "If you hybridize with wind, you create additional potential for the project."
By feeding both wind and solar into a single grid connection, developers smooth output across the 24-hour cycle, capture higher evening and night-time prices when wind typically peaks, and participate in balancing markets that reward dispatchability. EDP, the country's dominant utility, has already commissioned the Charneca das Lebres solar plant, which shares infrastructure with an existing wind farm and boosted local renewable output by 41%. Other hybrid proposals—combining wind, solar, and battery storage—are advancing through public consultation in municipalities such as Torres Vedras.
This pivot also eases pressure on environmental permitting: adding solar panels to a site that already hosts turbines often requires less extensive assessment than breaking ground in a pristine location. For landowners, it means dual or triple rent streams without doubling transmission upgrades.
Europe's Top Ten—For Now
With 6 GW of cumulative installed capacity, Portugal ranks in Europe's top 10 for wind power, trailing leaders Germany (77.7 GW) and Spain (33.2 GW). The autonomous regions contribute 106.4 MW: 63.8 MW in Madeira and 42.6 MW in the Açores.
Onshore, Viseu remains the national leader with 1,231.1 MW connected to the grid, followed by Coimbra (745.7 MW), Vila Real (696.3 MW), and Guarda (653.2 MW). Évora stands alone as the only continental district without wind generation.
Looking ahead, Serôdio argued that "the future lies in repowering," but stressed that "there is still, effectively, room to grow onshore." The key constraint is not geography—Portugal's Atlantic coastline and interior highlands offer consistent wind resources—but the speed and transparency of the permitting machinery.
Policy Prescriptions and What Comes Next
APREN and industry analysts are urging the Portugal government to adopt proven European mechanisms—contracts for difference (CfD) that guarantee a floor price for renewable electricity, and power purchase agreements (PPA) backed by public credit guarantees—to de-risk projects and unlock private finance. Centralized, digitized licensing platforms and dedicated staffing for environmental reviews are also high on the wish list.
In the first quarter of 2026, renewables as a whole covered 78.5% of mainland consumption, placing Portugal third in Europe for renewable penetration in power generation. Solar capacity, in particular, posted the continent's largest annual increase in 2025, and forecasts for 2026 remain bullish. Wind, however, lags that momentum.
Whether Portugal threads the needle—modernizing aging turbines, greenlighting new onshore parks, and launching offshore auctions in time to meet 2030 commitments—will determine not only the country's climate credentials but also the fate of billions in investment capital and thousands of skilled jobs. For now, the wind is blowing, but the sails remain only half-unfurled.
