Renewable Expansion — France’s Wind and Solar Acceleration Strategy

France has long been an underperformer in renewable energy deployment relative to its European peers. Despite possessing Europe’s second-largest land area, the continent’s third-largest exclusive economic zone, and some of the best solar irradiation in Western Europe, France generated only 27% of its electricity from renewables in 2024 (including hydroelectric) — below the EU average of 38% and far behind leaders like Denmark (84%), Portugal (61%), and Germany (52%). The gap is almost entirely attributable to wind and solar, where France has deployed approximately 25 GW of onshore wind and 21 GW of solar photovoltaic — roughly half the capacity of Germany in each category, despite having comparable land area and superior solar resources in its southern regions.

This underperformance reflects a combination of factors: the historical dominance of nuclear energy (which reduced the perceived urgency of renewable deployment), complex and lengthy permitting processes, intense local opposition to onshore wind (the “anti-éolien” movement), and inconsistent political signals about the role of renewables in France’s energy mix. The current government has committed to a significant acceleration, targeting 54 GW of onshore wind, 45 GW of solar, and 18 GW of offshore wind by 2035 under the Programmation Pluriannuelle de l’Énergie (PPE3) — but achieving these targets will require overcoming deeply entrenched structural barriers.

The PPE3 Framework

The Programmation Pluriannuelle de l’Énergie (PPE) is France’s statutory energy planning document, updated every five years, which sets binding capacity targets for each energy source. The PPE3, covering the period 2024-2035, was adopted following extensive public consultation and parliamentary debate. Its renewable energy targets represent a significant acceleration from the PPE2 trajectory.

For solar photovoltaic, the PPE3 targets 54-60 GW of installed capacity by 2035 (up from approximately 21 GW in 2024), requiring annual installation rates of approximately 5-6 GW — roughly triple the 2023 installation pace of approximately 3.2 GW. The strategy prioritizes ground-mounted solar on degraded land (brownfields, former quarries, military bases, motorway margins), rooftop solar on commercial and industrial buildings (made mandatory for new constructions above 500 m² under the Loi Climat et Résilience), and agrivoltaic installations that combine solar generation with agricultural production.

Agrivoltaics has emerged as a distinctively French approach to solar deployment, addressing the tension between renewable energy expansion and agricultural land preservation. French law (the Loi d’Accélération des Énergies Renouvelables of March 2023) establishes a regulatory framework requiring that agrivoltaic installations maintain the agricultural activity as the primary use of the land, with solar generation as a secondary, complementary function. Typical configurations include elevated solar panels over sheep grazing, vineyard-integrated solar canopies, and solar greenhouses. Companies like Sun’Agri, TSE (Technique Solaire), and Photowatt are developing specialized agrivoltaic systems adapted to French agricultural practices.

For onshore wind, the PPE3 targets 40-45 GW by 2035 (up from approximately 22 GW in 2024), requiring annual net additions of approximately 2-3 GW. This target is considered achievable technically but faces significant social acceptance challenges — onshore wind is by far the most politically contentious energy technology in France, with organized opposition movements in virtually every department where new projects are proposed.

The permitting challenge is stark: the average development timeline for a French onshore wind project, from initial site prospecting to commercial operation, is approximately 7-10 years — compared to 3-5 years in Germany or the Nordic countries. Approximately 70% of wind project applications face legal challenges (recours contentieux), with environmental associations, heritage preservation groups, and local residents’ committees filing appeals that can delay projects by 3-5 additional years. The administrative courts (tribunaux administratifs) that adjudicate these disputes are severely backlogged, with average case resolution times exceeding 18 months.

The Loi d’Accélération des Énergies Renouvelables (LAER) of March 2023 introduced several measures to accelerate permitting: the creation of “zones d’accélération” where municipalities proactively designate areas suitable for renewable development (reducing confrontational project-by-project battles), streamlined environmental impact assessment procedures for projects in pre-identified zones, a single authorization process (autorisation unique) replacing the previous multi-permit system, and enhanced mediation mechanisms to resolve disputes without litigation. As of early 2026, approximately 65% of French municipalities have designated acceleration zones — a significant achievement in a country where local opposition to renewable projects has been a primary deployment bottleneck.

Solar Market Dynamics

France’s solar market is experiencing rapid growth, driven by favorable economics, supportive regulation, and strong demand from commercial and industrial consumers. The levelized cost of utility-scale solar in France has declined to approximately €40-55/MWh, making it competitive with wholesale electricity prices and significantly below the regulated electricity tariff. Corporate power purchase agreements (PPAs) have emerged as a major driver of solar deployment, with companies like Amazon, TotalEnergies, Engie, and Air Liquide contracting for solar electricity to meet sustainability commitments and hedge against electricity price volatility.

The French solar supply chain remains underdeveloped relative to the market’s growth trajectory. France has minimal domestic solar panel manufacturing capacity — the Carbon community solar panel factory in Fos-sur-Mer (operating since 2023 with 5 GW annual capacity) and the Holosolis heterojunction cell factory in Sarreguemines (targeting 5 GW by 2025) represent the primary domestic manufacturing investments. Both facilities benefit from France 2030 and C3IV tax credit support, but face intense competition from Chinese manufacturers whose production costs remain 30-40% below European levels. The EU’s anti-dumping measures and Carbon Border Adjustment Mechanism provide some protection, but the economics of solar manufacturing in Europe remain challenging.

The residential solar market has grown rapidly following the introduction of enhanced self-consumption incentives and the rising cost of grid electricity (which increased approximately 30% between 2022 and 2024 due to ARENH reform and grid infrastructure cost passthrough). Approximately 450,000 French households had rooftop solar installations as of 2024, and annual residential installation rates have reached approximately 200,000 systems — though this remains below the trajectory needed to meet PPE3 rooftop solar targets.

The onshore wind sector in France operates in one of the most adversarial social environments in Europe. Anti-wind opposition has become a significant political force, with organizations like “Vent de Colère” (national federation of anti-wind associations), “Sites & Monuments” (heritage preservation), and hundreds of local committees mounting systematic challenges to wind project development.

The opposition draws on several arguments: landscape and heritage impact (France has over 45,000 monuments historiques and an architectural patrimony unmatched in Europe, creating ubiquitous proximity conflicts), biodiversity concerns (bird and bat mortality, habitat fragmentation), noise nuisance, property value depreciation (studies suggest 5-15% declines for properties within 1 km of wind turbines), and philosophical objections to the “industrialization of landscapes.” The political resonance of these concerns is amplified by France’s deep cultural attachment to its rural landscapes — the “terroir” concept that connects national identity to countryside aesthetics.

The government’s response has been to shift from confrontation to consent. The LAER’s zone d’accélération mechanism asks municipalities to volunteer sites for renewable development rather than having projects imposed by national policy. The Fonds territorial climat (territorial climate fund), which redistributes a portion of renewable energy revenues to host communities, is designed to create financial incentives for local acceptance. Community ownership models (projets citoyens), in which local residents invest in and share revenues from wind projects, have been promoted through Énergie Partagée and other cooperative financing platforms.

Despite these measures, the annual pace of onshore wind deployment — approximately 1.8 GW of net additions in 2024 — remains below the PPE3 trajectory. The repowering opportunity (replacing aging first-generation turbines with more powerful modern units, approximately doubling energy output per site without expanding the geographic footprint) offers a partial solution, as existing wind farm locations have already overcome the social acceptance barrier. Approximately 2 GW of French wind capacity is eligible for repowering before 2030.

Grid Integration and Flexibility

The increasing penetration of variable renewable generation creates grid management challenges that RTE must address through a combination of grid reinforcement, flexibility mechanisms, and market design evolution. France’s grid integration task is eased relative to some peers by the nuclear baseload (which provides dispatchable capacity to complement variable renewables) and by the country’s extensive hydroelectric fleet (approximately 25 GW, including 5 GW of pumped storage, providing fast-response flexibility).

However, the geographic concentration of renewable capacity creates localized grid constraints. Onshore wind is disproportionately concentrated in the northern half of France (Hauts-de-France, Grand Est, Bretagne, Normandie), while demand is concentrated in the Paris region, the Rhône-Alpes corridor, and the Mediterranean coast. Solar generation is strongest in the south (Provence-Alpes-Côte d’Azur, Occitanie, Nouvelle-Aquitaine) but must be transmitted to northern demand centers. RTE’s Schéma Décennal de Développement du Réseau identifies approximately €33 billion in transmission investments needed by 2035 to accommodate the PPE3 renewable targets, including new HVDC links, substation upgrades, and underground cable installations.

The development of energy storage is critical to managing renewable variability. France’s current storage capacity (dominated by pumped hydro) is insufficient for the high-renewable scenarios envisioned by PPE3, and significant investment in battery storage, additional pumped hydro, and hydrogen-based seasonal storage will be required. The CRE (Commission de Régulation de l’Énergie) is developing market mechanisms to incentivize storage investment, including capacity payments and frequency regulation service markets.

Hydroelectric Heritage and Concession Reform

France’s hydroelectric fleet of approximately 25 GW — the largest in the EU — represents a mature, fully depreciated renewable asset that provides invaluable grid services: baseload generation from run-of-river installations, peak generation from reservoir dams, and rapid frequency response from pumped storage. The fleet produces approximately 60-70 TWh annually (varying with rainfall), representing nearly half of France’s renewable electricity generation.

The hydroelectric sector faces a long-running governance challenge: the renewal of dam operating concessions. French dams are operated under concessions granted by the state, and approximately 150 concessions representing 12 GW of capacity have expired or will expire by 2030. The European Commission has pressured France to open these concessions to competitive bidding rather than automatically renewing EDF’s concessions, arguing that concession renewal without competition violates EU internal market rules.

France has resisted competitive tendering, arguing that hydroelectric assets are strategic infrastructure that should remain under national control. The compromise solution, developed over years of negotiation, involves the creation of a quasi-public structure that would manage concession renewals while maintaining public control over dam operations and ensuring that environmental and safety obligations are met. As of early 2026, the institutional framework remains under finalization, creating uncertainty for investment in hydroelectric modernization and capacity expansion.

Assessment and Outlook

France’s renewable expansion strategy faces a fundamental tension between ambition and execution. The PPE3 targets — 54 GW solar, 45 GW onshore wind, 18 GW offshore wind by 2035 — are technically achievable but require a step-change in deployment rates that has not yet been demonstrated. The permitting reforms of the LAER are necessary but probably insufficient to overcome the deep-seated social opposition to onshore wind development.

The most promising near-term growth vectors are utility-scale solar (where economics are favorable and social opposition is lower than for wind), rooftop solar (mandated for new commercial buildings), and offshore wind (where France’s maritime advantages are significant and visual impact concerns are reduced). Onshore wind growth is likely to remain constrained by social acceptance issues, making repowering of existing sites more important than greenfield development.

France’s nuclear-renewable integration represents a distinctive and potentially advantageous energy strategy. Unlike Germany (which is attempting a fully renewable system without nuclear baseload) or the UK (which is building nuclear and renewables but struggling with both), France can leverage its existing nuclear fleet as a complement to variable renewables — using nuclear for baseload while solar, wind, and storage handle peak demand and daily/seasonal variation. If the nuclear restart proceeds on schedule, France could achieve one of the lowest-carbon electricity systems in the world by 2040 while maintaining energy sovereignty and grid reliability. The renewable expansion is thus a complement to, not a substitute for, nuclear — a positioning that distinguishes France’s energy strategy from virtually all European peers.
