Wind Repowering and Greenfield Projects Boost Sovereign Electrification

The publication of the decree on the Multiannual Energy Program (PPE 3) on February 12, 2026, marks a significant milestone for French energy planning. Following years of delays, the framework establishes a roadmap for the 2026–2035 period. The launch of renewable energy tenders on April 2, 2026, including specific quotas for onshore wind, aims to put this framework into practice and reignite investment momentum. However, a planning framework alone cannot resolve the structural challenges currently weighing on the sector. Developers and investors face a marked slowdown in grid connections, rising costs for financing and equipment, and persistent issues with local acceptance.

Repowering involves renewing an existing wind farm at the end of its life cycle by replacing old turbines with higher performance technology. This approach often allows operators to double or triple installed capacity while maintaining the same land use, which can improve local acceptability. Public authorities have prioritized this strategy, as it optimizes existing assets to meet climate targets quickly. Yet, repowering is not a simple technical upgrade; it is a fully-fledged project subject to the Environmental Code and requires a precise analysis of whether modifications constitute a significant or substantial change.

Greenfield development, the construction of new wind farms on previously undeveloped land, remains essential for meeting the scale of electrification needed by 2030. The French economy is shifting toward massive electrification, driven by electric vehicles and heat pumps, which demands a net increase in capacity. While repowering consolidates existing assets, greenfield projects provide the necessary growth to satisfy economic and industrial requirements. Striking a balance between these two approaches is key for the sector’s success.

The specifications for the 11th period of the onshore wind tender, which closed in May 2026, have created a competitive tension between these two models. To be eligible, projects must hold a valid environmental authorisation, a requirement that complicates the development of greenfield sites. This restriction suggests that developers of new projects may face higher hurdles compared to those seeking to renew existing installations. The energy regulator has acknowledged that repowering projects are already more competitive on average, often submitting bids at a lower weighted price per megawatt-hour than new developments.

Handling Legal and Regulatory Uncertainty

Despite the launch of PPE 3, the French wind energy sector faces significant legal challenges. The decree is currently subject to litigation before the Council of State, with several appeals filed between February and April 2026 by associations and citizen groups. These challenges question the legality of the decree’s use and the substance of the energy trajectory. At least five appeals have been filed, though no decision to annul the decree has been issued, meaning it remains in effect during the proceedings. This legal uncertainty contributes to an environment where confidence is fragile.

The political setting adds another layer of complexity. The PPE 3 includes a review clause set for 2027, allowing for adjustments based on evolving electricity consumption and capacity data. While intended to provide flexibility, this mechanism introduces uncertainty regarding medium-term trajectories and investment signals. Investors require stability and consistency to commit capital over the long cycles required for wind projects. When policy signals shift or legal challenges linger, the willingness or ability of stakeholders to invest can erode rapidly.

The 11th period of the onshore wind tender, which concluded on May 21, 2026, illustrates the sector’s vitality despite these constraints. The 39 successful projects represented 808 MW of capacity, with repowering accounting for approximately 66 percent of the awarded volume. The tender was oversubscribed by more than three times, demonstrating that developer interest remains strong. This high level of competition suggests that the volumes available are insufficient to meet market demand, a gap that will likely require both repowering and greenfield development to fill.

While the French government seeks to balance local acceptability with the need for decarbonization, the current trajectory may not provide enough certainty to restore full investor confidence. The moderate target of 35 to 40 GW of onshore wind capacity by 2035, compared to the previous goal of 45 GW, sends an ambiguous signal. By favoring the renewal of existing farms, the strategy risks weakening the structuring of the value chain. To achieve energy sovereignty and meet long-term objectives, a coordinated approach that does not pit these two development models against one another is necessary.
