Energy Unplugged by Aurora

This week on Energy Unplugged, Marc Hedin, Head of Research for Western Europe & Africa at Aurora Energy Research, is joined by Rachel Fletcher, Director of Regulation & Economics at Octopus Energy, to tackle a question at the heart of Britain’s energy debate: why are electricity bills so high, and what would it take to bring them down? 

As the UK pushes ahead with electrification, Rachel argues that the challenge is no longer just about building more renewable generation. Instead, the conversation explores whether the current market design, network investment strategy, and approach to flexibility are fit for a rapidly changing power system. 

The discussion examines the drivers behind rising bills, the role of flexibility and electric vehicles in lowering system costs, and the policy choices that could shape the next phase of the energy transition. Rachel also shares her views on locational pricing, the future role of gas, and the reforms she believes would make the biggest difference for consumers. 

Main topics include: 

What is really driving high electricity bills in Great Britain 

How flexibility, batteries and EVs could reshape the power system 

The debate over grid expansion, market design and locational pricing 

The reforms needed to support electrification and lower costs

As we celebrate a milestone 300 episodes of Energy Unplugged, Richard Howard, Aurora Energy Research's Global Research Director, is joined by Aurora's regional Managing Directors from around the world to explore a defining question for the energy transition: what happens after the first phase of success?
 
 

For much of the past decade, the challenge was clear: deploy clean technologies at scale. Wind and solar needed to become cheaper. Investment needed to accelerate. Policymakers needed to create the right incentives. While significant work remains, that first phase has delivered enormous progress. 

 

The next phase may prove more difficult. The challenge is no longer simply building clean generation but adapting the systems around it. As renewable capacity continues to grow, grids are becoming congested, curtailment is rising, market designs are being tested, and new sources of demand are emerging. The energy transition's greatest challenge today may be managing the consequences of its own success. 

 

Drawing on perspectives from Europe, North America, Latin America, Asia-Pacific and Africa, this special episode examines whether power systems, markets and policymakers can keep pace with the technologies driving the transition forward. 

 

Taken together, these conversations suggest that the energy transition is entering a more complex and consequential phase. The first challenge was deploying clean technologies at scale. The next is integrating them into power systems that were never designed for a high-renewable world. From grid expansion and market reform to flexibility, storage and AI-driven demand, the coming decade will be defined not by whether the transition can grow, but by whether the system around it can keep up. 

 

You will learn about: 

How the energy transition is progressing across different regions of the world. 

Why renewable success is increasingly creating challenges around grids, markets, and investment. 

How batteries, flexibility, and electrification are reshaping power systems. 

What different regions can learn from one another's experiences. 

What needs to happen between now and 2035 to keep the transition on track.

This week on Energy Unplugged, Oliver Kerr, Aurora Energy Research’s Managing Director for North America, is joined by Arushi Sharma Frank, Founder of Luminary Strategies and one of the leading thinkers shaping the future of power markets in the age of AI. 

As data centre demand surges across the United States, electricity has become a critical constraint on growth. The challenge is no longer simply building more infrastructure - but finding new ways to use the grid more efficiently and connect large loads faster. 

Drawing on her work at the centre of recent market reforms in Texas, Arushi argues that flexibility, not just new transmission and generation, will be essential to unlocking the next phase of AI-led growth. The conversation examines how large electricity users could become active participants in the power system, helping to relieve constraints, improve reliability, and accelerate access to power. 

From regulatory innovation and grid planning to distributed energy resources and flexible computing, Oliver and Arushi discuss how power markets may need to evolve as electricity demand rises to levels not seen in decades. 

 

You will learn about: 

Why AI is transforming the way power systems think about large-load interconnection. 

How flexible demand could help unlock grid capacity and accelerate access to power. 

Why Texas is emerging as a testing ground for new approaches to grid flexibility. 

How batteries, distributed energy resources, and workload shifting could reshape power system planning. 

What utilities, policymakers, and large customers need to do to support the next phase of electricity demand growth.

This week on Energy Unplugged, Rodrigo Borges, Aurora Energy Research’s Market Lead for Brazil, is joined by Carla Primavera, Deputy Managing Director at BNDES, the Brazilian Development Bank. BNDES has been central to Brazil’s energy transition, financing renewables from early utility-scale wind and solar to the next generation of low-carbon technologies. 

Brazil’s power market is entering a new phase. Wind and solar have grown faster than demand and transmission infrastructure, driving curtailment, price volatility, and tougher project economics. Yet long-term demand growth is expected to trigger a substantial new investment cycle. 

Rodrigo and Carla discuss how Brazil can move from today’s oversupplied market to the next wave of energy investment, including how lenders are adapting to curtailment, revenue uncertainty, and more sophisticated financing structures. 

The discussion also covers grid expansion, storage, and flexibility, with Carla explaining how BNDES is approaching batteries, smart grids, sustainable fuels, low-carbon hydrogen, and why regulation will be key to Brazil’s next phase of growth. 

You will learn about: 

Why Brazil’s renewable energy success has led to new challenges around curtailment and price volatility. 

How project finance structures are evolving to address changing market risks. 

What role BNDES is playing in supporting Brazil’s next wave of clean energy investment. 

Why are batteries and other flexibility technologies becoming increasingly important to the power system. 

How Brazil can prepare for a new investment cycle as electricity demand begins to absorb today’s surplus capacity.

This week on Energy Unplugged, Oliver Kerr, Aurora Energy Research’s Managing Director for North America, is joined by Seyed Madaeni, Co-Founder and CEO of Verse. Drawing on decades of experience in power markets, energy storage, and grid software, Seyed shares his perspective on one of the biggest challenges facing the energy sector today: how to power the AI revolution. 

 

As data centre development accelerates across the United States, electricity has emerged as a critical constraint on growth. Utilities face mounting pressure to connect large new loads, while grid infrastructure, planning processes, and regulatory frameworks struggle to keep pace with demand. 

Oliver and Seyed discuss why flexibility may be one of the most powerful tools available to relieve pressure on the grid. From behind-the-meter batteries and on-site generation to smarter software and new planning approaches, the conversation explores how large electricity users could become active participants in the power system rather than simply consumers of it. 

 

The discussion also examines the role of data centres in reshaping electricity markets, the growing importance of “speed to power”, and the policy reforms needed to unlock grid capacity more quickly. As the AI race intensifies, the challenge is not just building more generation and transmission - it is finding smarter ways to use the infrastructure that already exists. 

  

You will learn about: 

Why electricity has become a critical bottleneck for AI and data centre growth. 

How flexible demand and behind-the-meter resources can help unlock grid capacity. 

Why software is becoming increasingly important in power system planning and optimisation. 

How the AI boom could reshape electricity demand, grid investment, and power markets over the coming decade.
