In this episode, Katharine Blacklaws speaks to experts from Leeds City Council, the University of Leeds and Star Refrigeration about the GeoGrid innovation project. Together, they explore how geothermal heat storage could transform heat networks by storing low-cost, low-carbon heat underground for months at a time. They discuss how seasonal heat storage could reduce electricity demand at peak times, lower operating costs, improve energy security and help scale heat networks as the UK electrifies heat.

In this episode, Sam Hollister speaks to Sam Peacock, Managing Director of Corporate Affairs at SSE plc, about why the UK needs to rethink how we measure the cost of energy. Rather than looking at electricity, gas and petrol separately, Sam argues that the transition to electrification means we should consider the total cost of energy across all three.

In this episode, Sam Hollister speaks to Bertalan Gyenes, Power Modelling Consultant at LCP Delta, and David Edmonds, Head of Portfolio Pricing at EDF Energy, about the growing impact of wind cannibalisation on the GB power market. As renewable generation continues to increase, periods of high wind output are pushing wholesale electricity prices lower, creating new challenges for investors, developers and offtakers. Together, they explore how these market dynamics are reshaping power purchase agreements (PPAs), influencing investment decisions, and raising important questions for future market design.

In this episode, Tom Smout speak to Johan Hernström, Head of Revenue at Alight, about why the traditional solar business model is changing and how combining solar, battery storage and innovative PPA structures could create a more resilient path forward.
As capture rates decline, negative pricing increases and balancing costs rise, renewable developers are being forced to rethink how projects are financed and operated. Johan explains why Alight is pairing PPA-backed solar with merchant battery storage, how this approach is changing relationships with lenders and off-takers, and what it means for the future of independent power producers.
