Redefining Energy

In May 2026, our co-host Laurent Segalen had the privilege of chairing a high-profile panel hosted by SolarPower Europe at its annual Solar Power Summit in Brussels, one of the leading gatherings for the European solar and energy storage sectors.  

In this episode, we bring you highlights from the hour-long conversation, featuring two distinguished industry leaders: Fredrik Andrén Sandberg from RWE and Hanna Kunzmann from EQT. Between them, their organisations oversee more than 10 GW of battery storage projects either in operation or under development, offering a unique perspective on the realities of financing and scaling storage assets.  

The discussion addressed one of the most important questions facing the energy transition today: the bankability of battery storage investments. As battery deployment accelerates across Europe and beyond, investors, developers, and policymakers are increasingly focused on understanding the risks and opportunities that will determine the sector's long-term attractiveness.  

The conversation examines battery bankability through four interconnected dimensions. First, technology risk: are batteries still exposed to meaningful technological uncertainty, or have the key challenges shifted towards commercial execution? Second, commercial risk: how should investors evaluate revenue models, merchant exposure, and the growing role of hybridisation strategies? Third, regulatory risk: what policy and market-design uncertainties could affect future returns, from evolving capacity mechanisms to unexpected rule changes? Finally, digital risk: how critical are cybersecurity, battery management systems (BMS), and energy management systems (EMS) in safeguarding performance and protecting asset value over the long term?  

The session attracted a packed audience in Brussels and has since been widely praised for the quality, depth, and practical insights of the discussion. Whether you are an investor, developer, policymaker, or simply interested in the future of energy storage, this episode offers a valuable window into how some of the industry's leading players assess risk and opportunity in one of the fastest-growing sectors of the energy transition.

Gerard and Laurent welcome Michel Boutouil, co-founder and CEO of Polarise, a leading European AI infrastructure provider and NVIDIA Cloud Partner based in Berlin. After discussing about what happens outside of a datacenter, it is time to dive inside one.  

Polarise is one of the few genuinely European NeoCloud companies — essentially a European counterpart to CoreWeave — specializing in GPU infrastructure for AI inference. Through its partnership with NVIDIA, Polarise designs its datacenters around the GPU rack itself, using liquid cooling from the outset rather than starting with a traditional real estate-first approach. The company has already developed AI factories in Germany, Norway and the UK.  

In the conversation, we explore the growing commoditization of large language models and why the real long-term value may lie in AI factories — facilities that are fundamentally different from conventional datacenters. Given Europe’s notoriously long grid-connection timelines, Polarise focuses on refurbishing brownfield sites with under 50MW of grid access instead of pursuing massive gigawatt-scale campuses. It’s a pragmatic “pod” strategy: adapt to the grid’s constraints rather than try to reshape the entire energy system.  

We also tackle the thorny issue of digital sovereignty. With the U.S. CLOUD Act allowing U.S. authorities access to data managed by American tech companies, it is fair to ask what hyperscalers are doing with European data — and whether Europe needs its own sovereign AI infrastructure. Polarise has secured €1 billion in backing from Swiss investor SWI Stoneweg Icona, but even that is modest compared with the hyperscalers’ spending power. For comparison, SpaceX has reportedly invested around $40 billion in Colossus 1 and 2 alone.  

So, what does the future of the European AI ecosystem look like? Michel’s answer is clear: Europe should not try to outspend China or the United States head-on. Instead, it should play to its strengths — smart execution, agility, flexibility, and the ability to learn quickly from the mistakes being made elsewhere.    

“Today’s show is supported by the BMW Foundation Herbert Quandt. The BMW Foundation unites leaders across sectors to develop solutions that foster an innovative economy and a future-proof society. A key focus is "Energy Transition & Climate Change," where the Foundation drives "International collaboration to accelerate the energy transition." With rising energy demands from AI and data centres, new partnerships, effective collaboration, and the exchange of science-based solutions and strategies are essential.”

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.

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.

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.
