As the electrification of heat increases and technologies like heat pump adoption grows, it's tempting to assume the gas network can simply be wound down street by street, in line with falling demand. But it’s not as simple as this: network topology, not customer count, decides when decommissioning is actually viable, and the UK gas network is nowhere close to that point today. Sam Wilson, Director of Energy System Operations at Cadent, joins the podcast to explain the engineering reality behind that constraint — and how things like pressure control, storage, and gas injection all factor into it. They cover: Why network topology, not customer count, decides when decommissioning is actually viable How gas goes from completely odourless at transmission pressure to detectable on your street. What it takes to step pressure down from around 90 bar in the transmission system, through off-takes and above ground installations, to roughly 30 millibars at a domestic appliance. How line packing turns the pipe network itself into short-duration storage, with operators raising or lowering in-pipe pressure to absorb daily demand swings. What's actually limiting how much biomethane and hydrogen can go into the network today, and why hydrogen can be blended in without any changes needed to downstream appliances.

Battery storage in Germany has a grid connection problem: far more projects want to connect than the grid can take, so Germany has scrapped first come, first served and moved to a maturity-based allocation scheme that rewards projects that are ready to build. But for 50Hertz and Germany's other transmission system operators, connecting BESS is only half the challenge. Merchant batteries could push grid congestion costs and grid fees up, or bring them down. Wilhelm Kiewitt, Head of Energy Economics at 50Hertz, one of Germany's four transmission system operators, joins Ed Porter to explain how a grid operator sees the battery boom from the inside. They cover: Why Germany scrapped first come, first served for grid connections, and how the new maturity-based scheme scores projects on land, permits and finance instead of speed. How 50Hertz went from a handful of transmission connection requests a year to more than 100, and why even the 14GW of batteries already holding grid reservations may not all get built. Should batteries pay more towards wider grid upgrades? Why Wilhelm says no, and why data centres are a different case. Dynamic grid fees or smaller bidding zones? Where Wilhelm and Ed disagree on the cleanest way to send batteries to where the grid needs them. Could merchant batteries cut Germany's roughly 4 billion euros a year in congestion management costs, or push them up? Building in Germany?

Battery storage investment in Europe now depends less on whether the revenue exists and more on how it gets financed. With Italy's first MACSE auction won largely by a single player while Germany's fully merchant market is pushing lenders towards shorter, tighter debt, investors have to work out what makes a battery project bankable without a long-term contract. Grace Kankindi, Deputy Head of Investment Management at Aquila Clean Energy, joins Ed Porter to walk through how she assesses battery investments across multiple European markets. They cover: - Why the first MACSE auction worked as designed, even though prices cleared low and one bidder took most of the contracts, and what new anti-concentration rules could change in round two. - What happens to Italian battery projects that miss out on MACSE, from tolling to the capacity market, and why Italian lenders still won't back fully merchant projects. - How lenders are financing merchant batteries in Germany, with debt terms of around 3 to 7 years instead of 15 to 20, and cash sweeps to pay debt down faster. - The risk investors most often underprice, the optimiser, and why the lowest profit share isn't always the cheapest deal as German two-hour battery revenues fall. - Why timing decides returns in smaller markets like Lithuania and Finland, why Poland is next on Grace's radar, and why she thinks contracted revenue is riskier than it looks. Want to stress-test how a German battery's revenues hold up as saturation sets in? Ko, Modo Energy's AI analyst, is built for exactly these questions.

Batteries earn volatile revenues, but lenders want fixed ones. Financial swaps that trade a fixed payment for floating battery revenue, from day-ahead spreads to full revenue indices, are how that gap is starting to close. Chris Kennedy, Founder & Managing Director at Miranda Energy, joins Ed Porter in Berlin to explain how battery swaps actually work, where basis risk hides, and why he treats power volatility as an asset class in its own right. They cover: - Why basis risk is the most misunderstood part of day-ahead TB swaps, and how round-trip efficiency, degradation schedules, payout caps and availability adjustments bring the swap closer to what the asset really earns. - How day-ahead swaps are evolving into total revenue swaps benchmarked to broader battery revenue indices like Modo Energy's, and why capturing more of the revenue stack cuts basis risk further. - Why fixed-for-floating battery swaps borrow the ISDA playbook from interest rate markets, and how a TB swap let a German solar portfolio hedge the duck curve without building a battery. - Why Chris sees volatility, not the depreciating battery, as the asset to own, and how ten-year TB swaps, credit-light offtakes for BESS SPVs and 245MW of fixed offtakes across Germany, Poland and Hungary set Amaranth Energy apart from the big trading houses. - Chris's contrarian view: the market puts too much weight on backwardation in the TB forward curve, when spreads may prove directionally persistent as solar continues to outpace flexibility.
