Engie CEO warns RN pricing plan would freeze European power investment
Catherine MacGregor's public challenge to National Rally's electricity market proposals puts France's largest utility in direct opposition to the far-right.
Catherine MacGregor, chief executive of Engie, on Tuesday (2026-06-23) publicly warned that proposals from France's National Rally party to dismantle marginal-cost pricing in European electricity markets would halt energy investment and undermine the continent's power market architecture.7
Marginal pricing, the system by which the most expensive generator dispatched sets the clearing price for all electricity sold in a given hour, has come under sustained attack from the RN as a driver of consumer bills. MacGregor's intervention carries weight because Engie operates across the European power supply chain, from gas import terminals to nuclear generation and renewable projects, making the company directly exposed to any pricing overhaul.7
The CRE, France's energy regulator, had already staked out a similar position. Its head told Montel on Thursday (2026-05-21) that marginal pricing was a "strong, robust and reliable" system that "should not be changed," attributing price volatility to market conditions rather than the pricing mechanism itself.2
The political backdrop is sharpening. Jordan Bardella, the RN president, has cast himself as "pragmatic on economics" and argued the party is "pro-business," but the pricing proposal sits awkwardly alongside that framing — replacing market-clearing prices would require either rationed generation contracts or direct price controls, both of which carry significant allocation risks for power investors.4
France's fiscal constraints add another complication. The country's borrowing costs are now broadly in line with Italy's, the result of political paralysis over a deficit running at 5.4 per cent of GDP, Economist analysis cited in May 2026 noted. The IFRAP Foundation, a French think-tank, estimated that RN's economic plans as a whole would add some €14bn to that deficit. That is a smaller number than comparable assessments of far-right programmes in Germany or the United Kingdom, but it narrows the fiscal space for any energy subsidisation that might need to accompany a market-structure change.3
The investment stakes MacGregor raised are concrete. TotalEnergies subsidiary Centre Manche Energies filed on Thursday (2026-05-29) for permission to build a 1.5 gigawatt offshore wind farm off the Normandy coast, a project estimated to cost €4.5bn. Assets of that scale require decade-long revenue visibility, which marginal pricing, for all its volatility, theoretically provides through competitive clearing. A shift toward administered prices would force developers to reprice risk across every long-duration asset in their French portfolios.6
France's broader role in European energy governance complicates the picture further. French officials pushed on Thursday (2026-05-07) for a toll system on EU "energy highways," the cross-border infrastructure proposed by the European Commission, signalling a preference to shape rather than obstruct European integration. Scrapping marginal pricing would be a harder departure. European electricity markets are tightly interconnected, and a French pricing overhaul without coordinated EU action would likely require permanent import controls or market-splitting measures that Brussels would be unlikely to endorse.5
Adding to the regulatory overhang is the Commission's probe into France's plan to subsidise the construction of six new nuclear reactors totalling 10 gigawatts at an estimated cost of €73bn, launched on a Tuesday (2026-05-19). The investigation already introduces uncertainty at the moment France is positioning nuclear as the long-term answer to power price volatility. MacGregor's public intervention, from the chief executive of a company with substantial nuclear exposure, reads partly as a defensive signal: political disruption to market architecture would compound the investment uncertainty already generated by the subsidy inquiry.1
ICE Endex TTF front-month gas was trading at €41.83 as of Friday's close (2026-06-27), with German base-load power at €97.85. Those levels underpin the revenue assumptions behind current European power investment plans. Whether the RN's pricing proposal remains electoral positioning or hardens into a governing programme is the variable that energy executives, including MacGregor, are now pricing into their longer-term capital decisions.
