    Why Would A German Battery Agree To Switch Off? - Green Flexbility

    21-07-2026 | 37 Min.
    Germany looks like Europe's most attractive battery storage market on paper: deep power price volatility, a fast-growing renewables build-out, and nearly three gigawatts of batteries already live. In reality, developers are navigating uncertain grid connection queues, gruelling commissioning phases, and a tolling market still working out how much risk is fair to price in.
    Christina Hepp, Director Strategy, and Leandra Boes, Director Asset Management, both at Green Flexibility, join Ed Porter to unpack what building and operating batteries in Germany actually looks like once the PowerPoint slide meets the grid.
    They cover:
    - What a Flexible Connection Agreement actually is and why this kind of trade-off is fast becoming the norm in Germany.
    - Why grid operators and battery companies have historically struggled to "speak the same language", and how a shared framework like REGIOlink helps translate one side's needs into the other's terms.
    - What actually happens in the final weeks before a large-scale battery switches on for real: the software integration, testing and last-minute troubleshooting that never makes it into a press release.
    - Why choosing to sell power on the open market versus locking in a steadier, pre-agreed deal is a much bigger and riskier decision than it sounds - and why Green Flexibility is betting on the option most peers shy away from.
    - Just how enormous Germany's battery storage pipeline has become: enough grid connection requests queued up that regulators have had to start filtering out the projects that aren't actually going to happen.

    Why Renewables Are Changing How Power Gets Priced - Renewable Exchange

    14-07-2026 | 44 Min.
    Many people picture a power purchase agreement as a 15-year mega-deal between a tech giant and a solar farm. In reality, 99% of UK PPAs look nothing like that. Power purchase agreements now sit behind a growing chunk of how the UK's electricity supply is sourced, and getting the price wrong could mean getting locked in well above the market rate for years.
    Ed sits down with Rob Ogden, Founder and CEO of Renewable Exchange - one of the UK's largest PPA marketplaces - to unpack how PPAs are actually priced, why REGO certificate prices have swung from over £20 to just a few pence, and what happens to Europe's ageing wind fleet as 20-year subsidies run out and thousands of turbines are pushed onto the merchant market.
    They cover:
    Why the "blue-chip" corporate PPA is the exception in a UK market dominated by short-term utility contracts, and how subsidy schemes from NFFO to CfD shaped that split.
    How negative and volatile power prices are forcing generators and off-takers to rethink how PPAs are priced and structured.
    The lessons from Covid and the Ukraine energy crisis on why locking into a 15-year PPA carries real pricing risk.
    Why matching thousands of small renewable generators with energy suppliers is such a hard problem to solve, and what it takes to build pricing infrastructure that can handle PPA demand spiking overnight.
    Why REGO prices have swung from over £20 to just a few pence, and the case for moving to 24/7 REGO matching.

    The Truth About Battery Fires - Gore Street Capital

    07-07-2026 | 43 Min.
    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. Dan Sherlock-Burke, Director of Asset Management at Gore Street Capital, joins Ed Porter for a technical look at how battery fire safety actually works - from the Moss Landing fire that shaped public perception, to the data that can flag a failing module weeks before it fails. He explains what really happens minute-by-minute when a cell enters thermal runaway, why most BESS fires trace back to operations rather than faulty cells, and why fire suppression isn't always the safeguard it appears to be.
    They cover:
    - Battery fire propagation: why "let it burn" is increasingly viable, and how modern container design has made fires spreading across a site vanishingly rare
    - BESS fire statistics: how EPRI's failure incident database shows a fall from around 4 incidents per gigawatt hour in 2018 to under 0.1 today, a 99% reduction
    - What causes battery fires: why only ~11% start with a faulty cell, while ~65% trace back to operations and integration
    - LFP vs NMC battery chemistry: lower combustion temperatures, no self-supplied oxygen, and why lithium iron phosphate still isn't "inherently safe"
    - Battery fire suppression: the contrarian case for why the wrong system can turn a fire into an explosion

    What Happens To Power Markets In a Heatwave? - MetDesk

    30-06-2026 | 37 Min.
    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 us through when they can trust what they're seeing and when they can't, and how they turn an uncertain forecast into something traders can actually act on. Along the way they cover wind droughts (or Dunkelflaute), a possible record El Niño, river levels that shut down power stations, and the rise of AI weather models
    They cover
    - How weather forecast accuracy isn't fixed: Why a day-ahead wind forecast lands within 10–15% around 80% of the time, but a shifted low-pressure track can swing output 30–40%.
    - Dunkelflaute explained: How a blocking high-pressure system causes a wind drought, and why the longest recent German event ran nine days in early November 2024.
    - El Niño and energy markets: Why a milder autumn means lower heating demand and gives traders reason to sell Q4 gas.
    - AI weather models vs traditional models: why AI is pulling ahead at the 10–20 day horizon while traditional models stay sharper on fine-scale detail.
    - Heatwaves and nuclear power: How 40°C heat in France and low river levels force nuclear curtailment and Rhine freight limits, echoing 2022.

    How Thermal Storage Decarbonises Industrial Heat - ENERGYNEST

    23-06-2026 | 37 Min.
    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 ENERGYNEST, joins Ed Porter to explain how a thermal battery works, why it competes with lithium-ion on cost, and why grid connections - not the technology - are the real constraint on industrial decarbonisation.
    They cover:
    - Why thermal storage functions like a battery on the energy markets but stores heat one-way in optimised concrete.
    - The medium-temperature "frying, drying and applying" range (roughly 150 to 300C) that sits above heat pumps and below cement and steel.
    - How decoupling thermal demand from the electricity price typically can cut the gas bill by around 50%.
    - Why a 20-foot-container module stores about two megawatt hours, stacks three high, and loses only around 2% of capacity per day.
    - Why a flexible, interruptible asset is exactly what congested grids need - and why Germany still lacks the flexible connection framework the Netherlands is rolling out.
