Portugal moves first with a sweeping energy package
Portugal has taken the most concrete step. In early 2025, the XXIV Constitutional Government approved a broad package to accelerate the energy transition and strengthen climate action. The centerpiece is a revision of Portugal’s National Energy and Climate Plan (PNEC), which sets binding targets for renewable capacity, efficiency gains and emissions reductions through 2030. Portugal already sources more than 60% of its electricity from renewables in a strong hydro and wind year, and the revised plan aims to push that share significantly higher. For ordinary households and small businesses, the most immediate change is licensing reform. The package simplifies permitting for rooftop solar, self-consumption installations and energy communities, three categories that allow consumers to generate their own power and reduce exposure to wholesale market swings. Shorter permitting timelines mean faster deployment and lower upfront costs. Portugal’s bet is that putting solar panels on rooftops and enabling neighborhood-scale energy cooperatives will do more to stabilize bills than any temporary price cap. The open question is execution speed. National approval is confirmed, but how quickly local permitting offices, grid operators and financing institutions adapt to the new rules will determine when consumers actually feel the difference. Grid connection queues and municipal bureaucracy have historically slowed renewable projects across southern Europe, and Portugal is not immune.Spain confronts a grid bottleneck
Spain’s renewable buildout is among the fastest in Europe. The country generated roughly half its electricity from wind and solar in 2023, a share that continues to climb. But that success has created a new problem: the grid cannot always absorb what renewables produce. The OECD’s Economic Survey of Spain 2025 dedicates an entire chapter to this challenge. It documents how grid congestion and curtailment are forcing operators to waste clean electricity in regions where generation outpaces transmission capacity. The result: consumers do not receive the full price benefit of Spain’s growing wind and solar fleet because cheap power that could displace expensive gas-fired generation never reaches them. The OECD calls for faster investment in transmission infrastructure and battery storage, arguing these are the missing links between Spain’s renewable ambitions and actual household savings. The report also revisits the “Iberian exception,” the joint Spanish-Portuguese gas price cap that ran from June 2022 through December 2023 and temporarily shielded consumers from the worst of the energy crisis. Whether Madrid would revive a similar mechanism in a future price spike remains an open political question, with no current policy document confirming plans either way. For Spanish households, the practical picture is mixed. More renewables are being built every year, which puts downward pressure on wholesale prices during sunny and windy hours. But until grid upgrades and storage catch up, a significant share of that cheap power goes to waste, and bills stay higher than the installed capacity alone would suggest.France balances nuclear and renewables
France occupies a different position from its Iberian neighbors. Its electricity system is anchored by a nuclear fleet that supplies roughly 65% to 70% of national generation, giving French consumers a buffer against gas price swings that Portugal and Spain lack. But that buffer has limits: when an unprecedented number of French reactors went offline for maintenance and corrosion repairs in 2022, wholesale prices surged and France became a net electricity importer for the first time in decades. The experience accelerated French interest in diversifying beyond nuclear. Paris has committed to expanding offshore wind capacity and is gradually increasing onshore wind and solar deployment. However, compared with Portugal’s newly approved licensing reforms or the OECD’s detailed grid-investment roadmap for Spain, France’s specific near-term measures to accelerate renewables and curb bill volatility are less clearly documented in primary government sources as of spring 2025. What is clear is the strategic direction. France’s long-term energy programming law (Programmation pluriannuelle de l’énergie) envisions a rising share of renewables alongside refurbished and new nuclear capacity. For French households, the nuclear backbone provides more price stability than most European neighbors enjoy, but the 2022 episode demonstrated that relying on a single technology carries its own risks. The renewables buildout is meant to close that vulnerability.Cross-border coordination: the missing piece
Portugal and Spain share a peninsula, an electricity interconnection and, during the Iberian exception, a joint market intervention. Logically, coordinated investment in cross-border transmission and shared storage could amplify the bill-stabilizing effects of each country’s national efforts. Excess solar generation in southern Spain, for instance, could flow to Portuguese consumers during peak demand, reducing waste and price divergence on both sides. Yet no integrated plan for joint curtailment management or coordinated storage deployment has been published by either government. The EU’s revised electricity market regulation, adopted in 2024, encourages cross-border cooperation and long-term power purchase agreements, but translating that framework into Iberian-specific infrastructure projects will take political agreement and capital that neither country has publicly committed to this purpose. France’s interconnections with Spain are also relevant. Greater cross-border capacity would allow French nuclear baseload to backstop Iberian renewables during low-wind periods, and Iberian solar surpluses to flow north. The Bay of Biscay subsea interconnector project, backed by EU funding, aims to roughly double Franco-Spanish electricity exchange capacity, but construction timelines stretch into the late 2020s.What this means for household electricity bills
For consumers across southwestern Europe, the policy direction is consistent: more renewables, simpler permitting, better grids. Each of those steps points toward lower and more stable electricity prices over time, because wind and solar have no fuel cost and are not subject to the commodity-market swings that sent gas-linked bills soaring in 2022. But the timeline matters enormously. Portugal’s licensing simplification could begin delivering results within months if local authorities move quickly, giving households and small businesses a faster path to rooftop solar and energy community participation. Spain’s grid and storage investments, by contrast, are multi-year infrastructure projects; the OECD’s recommendations will not translate into lower bills until transmission lines are built and batteries are installed, a process that typically takes three to five years from approval to operation. France’s trajectory is the slowest to read, with nuclear providing near-term stability but the renewables acceleration still awaiting the kind of concrete, documented reform packages that Portugal has already approved. None of this guarantees immunity from the next energy shock. A severe drought reducing Iberian hydropower, a prolonged European gas supply disruption or another wave of French nuclear outages could all push prices higher regardless of renewable capacity gains. What the current policy push does is narrow the exposure. Every megawatt-hour generated by a rooftop solar panel or a wind farm onshore is one that does not need to be priced against an international gas benchmark. The faster these three countries can shift that balance, the less their households will feel the next global energy disruption on their monthly bills.
