EP. 278 Nat Bullard on Decarbonisation in the Age of AI

Energy Unplugged by Aurora

Show Notes

This week on Energy Unplugged, we’re joined by Nat Bullard, co-founder of Halcyon, an AI-enabled energy information platform, and one of the sector’s most influential data storytellers. He joins Hugo Batten, Aurora’s Managing Director APAC, and Oliver Kerr, Aurora’s Managing Director USA, to unpack the 2026 edition of his annual “Decarbonisation” presentation - a sweeping, data-led assessment of where the global energy transition is accelerating, stalling, and surprising us. Nat brings two decades’ experience analysing energy, technology, markets and finance. Formerly Chief Content Officer at BloombergNEF and now also an advisor to Ember and Arcadia, he draws on deep market insight to separate structural trends from short-term noise. From record solar and battery deployment in the US, to flat real-terms clean investment globally, to China’s extraordinary scale in electrification and manufacturing, the conversation explores a world adding more of everything - fossil fuels and renewables alike - while grappling with grid constraints and rising electricity demand. The discussion also examines cooling demand in developing economies, China’s emergence as a global electrostate, and the profound uncertainty surrounding AI-driven load growth and data centre interconnections in the US - where the bottleneck may be demand connection as much as generation capacity. You will learn:

Why the energy transition appears contradictory - with record clean deployment alongside continued fossil growth.

How cooling demand in emerging economies could rival or exceed AI as a driver of electricity growth.

What China’s scale in electrification, batteries and EVs means for global supply chains and competitiveness.

Why grids and interconnection queues may prove the decisive constraint in the next phase of the transition.

Registration for the leading annual gathering of the European energy industry – the Aurora Spring Forum, taking place on 29th April 2026, in London is open - a one-day deep dive into the biggest strategic questions shaping Europe’s energy transition, plus top-tier networking and a live recording of Energy Unplugged.

This week on Energy Unplugged, Emma Woodward, Principal in Aurora Energy Research’s GB & Ireland Advisory team and GB Flexible Energy Lead, is joined by Peter Kavanagh, CEO of Harmony Energy. Britain has built one of Europe’s most mature battery markets, largely without subsidy. But success brings its own complications. As batteries scale, the debate is shifting from whether the technology works to whether the market around it does. Merchant revenues remain volatile; projects can spend years waiting for grid and planning approvals, and batteries are still not always fully utilised when they could provide a cheaper alternative for balancing the system. At the same time, support for long-duration storage raises a more uncomfortable question: could policy designed to accelerate storage end up distorting a market that has already proved it can compete? For Peter, the message is increasingly simple: batteries have demonstrated their value. Now the challenge is removing the barriers that stop them delivering more of it. Main topics include:

This week on Energy Unplugged, Jose Munoz, Market Lead for Spanish-speaking South America at Aurora Energy Research, and Melissa Carreño, Product Manager for Peru and Colombia, are joined by César Butrón, Chairman of the Board of COES, Peru's national system operator. For two decades, Peru has benefited from some of the cheapest electricity in Latin America, supported by abundant low-cost gas from Camisea. But the conditions that shaped that success are beginning to change. Demand is rising, cheap gas can no longer be taken for granted, and investors are struggling to finance new renewable projects despite strong resources and significant interest in the market. At the same time, policymakers face difficult decisions around gas infrastructure, battery storage, transmission expansion, and system reliability. Drawing on decades of experience at the centre of Peru's power sector, César explains why the country is not facing a shortage of electricity, but a potential shortage of affordable electricity, and what that means for Peru's next phase of development. Peru's challenge is no longer keeping the lights on. It's deciding what will power them next. Main topics include:

This week on Energy Unplugged, Richard Howard, Global Research Director at Aurora Energy Research, is joined by Michael Tobin CBE, one of the pioneers of the European data centre industry, former CEO of TelecityGroup and Non-Executive Director at Five Nines Group, alongside Sebastian Murphy, Director of Development & Innovation at Five Nines Group, to explore what it really takes to deliver data centre projects in Europe. Driven by AI, cloud computing and digitalisation, data centres are becoming one of the fastest-growing sources of electricity demand worldwide. But as power constraints, permitting challenges and supply chain bottlenecks intensify, can Europe remain competitive in the global race to build the infrastructure that will underpin the next generation of AI? Michael and Sebastian pull back the curtain on the realities of delivering data centres at scale, from securing scarce grid connections and navigating planning hurdles to managing supply chains, construction risk and ever-tightening sustainability requirements. They discuss why Europe's established data centre hubs are running out of room to grow, how regional markets are emerging as the next frontier for investment, and why access to power has become the industry's defining challenge. The episode also examines the shift towards AI inference facilities, the rise of behind-the-meter power solutions, and whether Europe has the regulatory framework needed to compete with the US and China. Along the way, the guests share firsthand insights from the front line of data centre development and make the case for what needs to change if Europe is to remain a serious player in the global AI race.
