How dangerous are battery storage fires, really? Despite the headlines, grid-scale battery fire failure rates have fallen 99% since 2018 - from around 4 incidents per gigawatt hour to under 0.1. Even as global deployment scaled into the tens of gigawatt hours. Most people still picture a whole site going up in flames. The engineering tells a very different story.

The atmosphere is unpredictable, and weather forecasts are far more reliable on some days than others. For anyone trading power or gas across Europe, knowing the difference is everything. It's what separates a confident call from an expensive guess. In this conversation, Ed is joined by Matt Dobson - Head of European Energy Forecasting and Emma Patmore, Energy Meteorologist from MetDesk. They walk...

Two thirds of industrial energy demand is heat, not electricity, and most of it still runs on gas. Thermal storage converts cheap electricity into heat, stores it in concrete, and dispatches it when the factory needs it, undercutting the gas bill even though gas is cheaper per unit on average. Alex Robertson, CEO of Energy Nest, joins Ed Porter to explain how a thermal battery works, why it compet...

Germany's battery storage market is booming - but a saturation crunch is coming, and most investors aren't ready for it. The question is which revenue streams hold up, and which collapse the way they did in GB, Texas, and Australia. Ed sits down with Till Stehr, German Research Analyst, and Cosima from the Advisory Services Team at Modo Energy, to map the real structural drivers, and risks, behind...

Most battery revenue projections stop at the day-ahead auction. But the optimisers running multi-gigawatt BESS portfolios argue that's where the money is being left on the table - re-trading a battery through intraday, balancing, and ancillary services can add 50% or more to revenue, and battery offtake structures like floors, tolls, and swaps only make sense once you understand how that value act...

The scope of the National Energy System Operator - or NESO - has expanded from running the electricity system to planning Britain's whole energy system across electricity, gas and hydrogen, all while delivering connections reform and steering toward Clean Power 2030. That transformation is reshaping everything from how Britain plans its grid 20 years out to how it keeps the lights on tonight. Ed P...

Three years ago, the best price for a ready-to-build solar project in Spain was €200,000 per megawatt — today it is €50,000. Batteries have moved the opposite way, with ready-to-build prices climbing to around €100,000 per megawatt and a 30GW pipeline now stacking up behind them. Ed Porter sits down with Carmen Izquierdo Serrano, founder of nTeaser, the renewable energy marketplace where many of S...

Chris Stark is Head of UK’s Mission for Clean Power, As Head of Mission Control at DESNZ, no one sees the constraint costs, grid bottlenecks and reform of National Pricing trade-offs more clearly. The UK is building a clean power system at a pace not seen since the 1960s, connecting record volumes of wind and solar while transmission, storage and gas all reshape around them. Constraint costs have...

Germany sits at the centre of Europe's energy transition: over 800 distribution networks, deep intraday markets, and a flexibility gap roughly 40 times its battery fleet. But the real question isn't whether the market is big - it's whether it saturates as battery capacity grows, or scales for years yet. Philipp Man is co-founder and CEO of Terralayr. He joins Ed Porter to unpack the operational re...

Developing battery storage in emerging markets isn't a technology problem - it's a regulatory, offtake, and capital problem. The frameworks, offtake structures, and capital mandates weren't built for storage and that gap is exactly where the risk sits.

Spain has approximately 42GW of utility-scale solar and 50GW when rooftop is included, yet less than 100MW of grid-connected battery storage. In February, solar capture rates hit €1.30 per megawatt hour, a fraction of the €30–35/MWh needed for a solar project to break even. So why hasn't battery storage followed the solar boom and could it be the key to rescuing solar revenues? Pablo Martinez Serr...

Smart EV charging isn't just about saving money on your electricity bill, it's quietly becoming one of the most scalable sources of grid flexibility in Great Britain. Ohme has run the numbers: incentivising 22,000 customers to plug in more often drove a 32–37% increase in plug-in frequency, unlocking dispatchable flexibility across 60 National Grid events. In this episode, Ed is joined by Joshua W...

Battery storage looks simple - a steel box that charges when prices are low and discharges when they're high. But financing a BESS project in Europe means underwriting a trading position: convex revenues, volatile returns, and a growing menu of contractual choices that each shift the risk profile in a different direction. Lisa McDermott, Managing Director and Head of Energy Transition Project Fina...
