France faces strategic choice in accelerating electrification amid power surplus and energy policy uncertainties

France’s grid operator is urging a rapid, economy-wide shift to electricity to curb fossil fuel imports and underpin industrial revival, warning that delays risk locking the country into a slow and strategically exposed decarbonisation pathway.

Réseau de Transport d’Électricité (RTE) sets out the case in its 2025 forecast, arguing that France’s largely low-carbon power fleet , a generation mix it says is about 95% decarbonised , represents a structural advantage that should be mobilised to replace oil and gas across transport, industry and buildings. According to the original report, hydrocarbon imports currently drive an annual trade deficit in the order of €50bn–€70bn, and briefly reached nearly €120bn during the 2022 energy shock; electrification, RTE contends, would reduce that exposure while supporting reindustrialisation.

But RTE warns the current pace of uptake is insufficient. The operator has revised down its 2035 demand forecast by roughly 35 TWh versus its 2023 outlook, reflecting weak economic growth, the slow roll‑out of electric vehicles and hydrogen production, and persistent energy‑saving behaviours introduced since 2022. That mismatch has produced a temporary supply surplus: Reuters reporting notes power output is outpacing demand, with wholesale prices at their lowest since mid‑2018. Industry data and RTE’s analysis together suggest the excess capacity could persist through 2028 unless consumption accelerates.

The policy context is critical. Government officials are due to finalise the long‑delayed multiannual energy planning bill (PPE) before Christmas, a decision Reuters reports has been postponed by political disagreement over the balance between renewables and nuclear. RTE recommends a dual‑source approach: its executives caution against pitting nuclear against renewables and argue the system’s stability and economic efficiency depend on deploying both. The grid operator also points to two practical responses to today’s overcapacity , speed up electrification in low‑consuming sectors, or slow deployment of renewable capacity , and stresses the latter would be economically inferior and could damage nascent domestic industries tied to renewables.

The economic signals are already shifting corporate and market calculations. Fitch Ratings has warned that prolonged low market prices are eroding EDF’s earnings and its capacity to finance an ambitious nuclear build programme, noting year‑ahead prices have fallen about 30% since early 2025. That warns of a potential funding tension between keeping power affordable and sustaining the investments required to decarbonise supply and support electrified demand.

RTE is also investing to prepare the network for higher electrification. The operator’s long‑term plan, which the French press reports values at about €94bn to 2040, envisages extensive reinforcement and renewal of the high‑voltage network, large‑scale pylon replacement and adaptation to climate risks. The company says these measures are designed both to accommodate more distributed renewables and to connect new industrial loads, from electrified process heat to large‑scale electrolysis for hydrogen.

For businesses engaged in industrial decarbonisation, the implications are twofold. First, policy and grid readiness create a window to shift energy‑intensive processes to electricity while leveraging a low‑carbon power mix that can materially reduce supply‑chain carbon and import risk. Second, the interaction between market prices, grid investment and political choices on the PPE means commercial planning must factor in price volatility, potential capacity curbs on renewables and the financing constraints on major utilities.

RTE frames electrification as a strategic choice: reducing dependence on geopolitically sensitive fossil fuel suppliers and anchoring higher value manufacturing in France. The operator’s economic lead, Thomas Veyrenc, told RTE’s publication that electrification should be treated as much as a sovereignty and industrial policy as a climate measure. RTE’s chairman, Xavier Piechaczyk, has likewise warned against creating antagonism between energy sources, saying France’s future system must pragmatically rely on both nuclear and renewables to remain stable, according to the company’s communications.

In short, RTE’s forecast presents a familiar paradox for decarbonisation planners: a near‑term power surplus alongside an urgent, structural need to electrify energy uses if France is to cut import bills, meet climate targets and reindustrialise. The coming weeks’ policy choices on the PPE and the pace of network investment will shape whether that surplus can be converted into a durable competitive advantage for electrified industry, or whether it becomes a drag on the profitability of the companies (and the political will) needed to deliver the transition.
