Energy transition policy and regulation in France: the investor's reading grid

A session built for investors, not for lawyers

On 20 October 2025 I ran a session for the Silk Road Business School with a delegation of investors and executives looking at the French energy market. The brief was precise: not energy law for its own sake, but the exact points where regulation creates or destroys value in an investment case.

The session was therefore built in five blocks: the strategic framework, the ecosystem of players, the profitability mechanisms, the operational route a project has to travel, and the value creation areas beyond mature infrastructure.

The hierarchy of texts: from the European package to PPE-3

France does not have one energy policy, it has a stack of documents, each committing to a different horizon and a different level of constraint. The European Fit for 55 package and the RED III directive set the continental target. The 2019 Energy-Climate Act anchors carbon neutrality at 2050 and a 40% reduction in fossil fuel consumption by 2030. The 2023 APER Act then moved the subject from principle to execution, creating acceleration zones and simplifying siting.

For an investor, the decisive document remains the multiannual energy programme. PPE-3 covers 2025-2035 and sets the trajectory by technology: 48 GW of solar PV in 2030, then 55 to 80 GW in 2035; 3.6 GW of offshore wind in 2030, then 15 GW in 2035; and up to 8 GW of electrolysis. RTE's Energy Futures 2050 scenarios provide the upstream analytical base, from a 100% renewable mix to a mixed scenario keeping 24 GW of existing reactors and adding 27 GW of new capacity.

The ecosystem: knowing who decides what

A significant share of project delay comes from a naive reading of governance. The DGEC drafts the PPE and the national low-carbon strategy, the CRE runs the tenders and reviews tariffs, RTE and Enedis control grid connection, ADEME and Bpifrance provide funding and de-risking, and prefectures and local authorities arbitrate local acceptability.

These circuits are not sequential. They move in parallel and at different speeds. A project is not managed as a sequence of permits, it is managed as a multi-institutional programme whose milestones have to be synchronised.

How profitability is actually built

The central mechanism is the contract for difference top-up (complément de rémunération): the producer sells on the market and receives or pays back the gap against the reference price set by the tender. The practical consequence is that the price bid into the tender becomes the single most structuring variable in the business plan.

CRE tenders give an immediate reading of competitive tension: for the March 2025 ground-mounted solar round, 925 MW tendered for 887.46 MW awarded. A tight market, with no massive oversubscription, where margins are decided by cost of capital and site quality.

Profitability is then built by stacking: the contract for difference top-up, the capacity market, guarantees of origin, corporate power purchase agreements and the monetisation of ancillary services. A single revenue stream rarely produces a bankable case.

The two bottlenecks to address first

Grid connection has become the primary schedule risk. Queue saturation moves the critical path from permitting to the network, and a perfect site that is badly connected remains a non-productive asset.

The second is foreign investment screening. The procedure allows thirty working days for a first decision, with a further forty-five working days if an in-depth review is opened. The 2024 report shows activity up 27% and, more importantly, 54% of authorisations granted subject to conditions on employment, R&D or production location. This screening is not an administrative formality: it is an industrial policy instrument that has to be built into deal structuring very early.

The second engine: four areas beyond the megawatt

The second part of the session covered the segments where competition is less mature than in wind and solar.

Storage and flexibility first, with a value pool estimated by RTE at around €3 billion in annual savings, and a need still poorly covered beyond four hours that flow batteries target directly. Then heat decarbonisation, a large market backed by ADEME's Fonds Chaleur, which funded 1,350 new installations in 2024 and subsidises up to 45% to 55% of the initial investment in deep geothermal. Circular economy and critical materials, with solar PV recycling where silicon accounts for around 2.9% of mass but 40% of value, and the EMILI project at Échassières targeting 34,000 tonnes of lithium hydroxide per year from 2028. Finally industrial deeptech, where French greentech has become the country's leading fundraising sector.

What the delegation left with

A checklist, not a summary: does my project fit PPE-3 and RTE's network plans, is my grid connection secured and dated, is my foreign investment screening file anticipated with its likely conditions, are my revenues stacked or dependent on a single mechanism, and is my public counterpart identified by its real role rather than by its name.
