    234. Engie, the remarkable turn around (live from Eurelectric Power Summit) - Jun26
    Jun 22 2026
    At the Eurelectric Power Summit 2026 in Helsinki, Laurent had the opportunity to sit down with Catherine MacGregor, CEO of ENGIE and Vice President of Eurelectric, for a wide-ranging discussion on the key issues shaping Europe's energy future.

    We began with the themes at the heart of Eurelectric’s agenda this year: security of supply, affordability, competitiveness, and the challenges and opportunities created by the rapid growth of data centres.

    One of the most striking insights from our conversation was that Europe does not have an electrification technology problem — it has an electrification coordination problem. This was also the central conclusion of the report Power Couples: Enhancing Industrial Competitiveness through Electrification, launched by Eurelectric and Accenture at Power Summit 2026. The report finds that electrification projects rarely fail because technology is unavailable. Instead, they stall when power economics, grid access, infrastructure delivery, financing structures, and industrial investment timelines are not aligned.

    The proposed solution is a new delivery model: “Power Couples”, bringing together industrial players, utilities, technology providers and capital partners to accelerate deployment at scale.

    We also reflected on ENGIE’s remarkable transformation under Catherine’s leadership over the past five and a half years. The company’s strategy has been defined by two parallel moves: more than €15 billion of divestments from fossil and legacy assets, alongside concentrated investments in renewables, networks, batteries, and regulated infrastructure — all while maintaining strong financial discipline, with net debt-to-EBITDA around 3.

    The results have been impressive. Since 2021, ENGIE has delivered the strongest risk-adjusted equity performance among major European utilities, combining substantial dividend distributions with significant share-price appreciation. With an annualised IRR of roughly 20.5% since January 2021, ENGIE has outperformed the net returns of many leading global infrastructure investors, effectively delivering private-equity-style returns with public-market liquidity.

    Our discussion also covered ENGIE’s leadership in power purchase agreements (PPAs), its support for 24/7 Scope 2 accounting, the recent acquisition of UK Power Networks, progress in EV charging infrastructure, and its fully integrated strategy for data centre development.

    Finally, we explored ENGIE’s investment plans for the years ahead and the broader structural shift underway across the energy system: the continued transition from molecules to electrons.

    233. To predict the future, “In BNEF we Trust” - Jun26
    Jun 15 2026
    The International Energy Agency (IEA) and the International Renewable Energy Agency (IRENA) have made significant progress in recent years. Yet they remain largely top-down institutions shaped by policy priorities. When trillions of dollars in investment decisions are at stake, investors and operators increasingly turn to Bloomberg New Energy Finance (BNEF) and its team of more than 400 specialists.

    Why does BNEF command such trust? BNEF combines Bloomberg’s unparalleled market data capabilities with deep expertise in batteries, solar, electric vehicles, and electrification. Unlike many international agencies, BNEF operates without a political mandate or advocacy agenda. Its bottom-up analysis provides investors with a more practical view of market realities than traditional top-down forecasts.

    In this episode, Gerard and Laurent welcome Albert Cheung, CEO of BNEF, to discuss the findings of the New Energy Outlook 2026. The discussion begins with a review of NEO 2020. BNEF was notably accurate in forecasting the "electrons" side of the transition—solar, batteries, and EVs—while overestimating the pace of hydrogen and carbon capture deployment. Even so, its forecasting record remains among the strongest in the industry.

    Looking ahead, NEO 2026 projects a rapidly electrifying global energy system. Solar power, batteries, EVs, and heat pumps are reshaping demand while reducing exposure to fossil-fuel price shocks. Oil demand is expected to decline as EV adoption accelerates. Gas demand may continue growing in the near term to support rising electricity consumption, but both oil and gas fall sharply under stronger net-zero pathways.

    By 2032, solar is projected to become the world's largest source of electricity. Battery storage will scale rapidly, enabling more flexible and resilient power systems.
    The report also makes clear that, despite substantial progress—especially in China—current technologies and policies are still insufficient to fully achieve global net-zero goals. However, the gap between ambition and reality is narrowing thanks to energy security concerns, declining costs, and continued technological progress.

    Overall, it was a thoughtful, insightful, and hopeful conversation. The energy transition is advancing. We are getting there.

    232. GB’s NESO: the “cool” operator - Jun26
    Jun 8 2026
    Gerard and Laurent have the pleasure of welcoming Fintan Slye, CEO of NESO — Great Britain’s National Energy System Operator.
    In a lively and wide-ranging discussion, we explored NESO’s governance and its critical role across the British energy system: from real-time system operation — balancing supply and demand every second — to whole-system planning, market design, and transmission network operation.
    We covered an extraordinary breadth of topics: balancing costs, electricity prices for consumers, energy security, and the challenge of delivering Power 2030 in a system increasingly reliant on renewables. We discussed batteries, the evolution of balancing markets, the explosive growth of datacenters, and the ever-growing grid connection queue — and, above all, how to keep the entire system stable and efficient through this transformation.
    One of the most fascinating parts of the conversation focused on datacenters. NESO is currently facing more than 100GW of connection requests, while Fintan estimates that only 8–12GW are likely to materialise. He shared the three key criteria NESO uses to prioritise and filter applications — a crucial issue as electricity demand enters a new era.
    Fintan is also a strong advocate for interconnectors. We discussed the strategic value of the current fleet and the long-term vision for expanding connections through the North Sea Islands and potentially even towards Canada.
    Throughout the conversation, one message came across clearly: there is a highly competent team at the helm of the GB energy system, and the grid will continue to improve through investment, innovation, and digitisation.
    Fintan embodies the calm confidence you want from the person helping run one of the most complex energy systems in the world. The ultimate “cool” operator.
    NESO operates today’s electricity system and designs tomorrow’s energy system to deliver reliable, clean and affordable energy for Great Britain. Find out more here: https://www.neso.energy/
