22 SEP 2026 · 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.

15 SEP 2026 · The grid is swapping spinning turbines for grid forming inverters, and something is getting lost in the trade. A turbine could always throw 5 times its normal output to clear a fault, for free, using nothing but physics. Inverters can only manage around 1.5 times theirs. So if renewables are going to take over, where does that missing strength come from instead?Ben Braun is Chief Engineer at Fluence, where he's spent his career working on power electronics - from batteries to the grid. In this episode, he breaks down grid forming vs grid following inverters for everyone without an electrical engineering degree.They cover:- Why "grid forming is slower" than grid following - and why that slower response is actually what makes it more stable in a fault.- Why NESO in GB and AEMO in Australia are chasing completely different things from grid forming batteries.- Why grid inertia disappears as spinning turbines retire, and how a sudden burst of power from a battery can fake it.- Why volatile AI training loads are turning data centres into miniature grids of their own, and how batteries are used to stop that volatility ever reaching the wider network.- Why Ben's biggest concern isn't too little fault current on the grid, but too much of it - and why that could force a wave of grid upgrades most people haven't priced inWant to see which grids are paying for inertia and fault current today, or where the next stability tenders are opening?

8 SEP 2026 · Joe McDonald says close to 30% of a business power bill can go to trading desks, balancing costs and wholesale market fees most customers never see. Behind suppliers can sit five or six more intermediaries, each taking a cut before the energy ever arrives. Is that a market working as designed, or one taking more than it should?Joe is Founder & CEO of Tem Energy, and has spent over a decade inside the middle of the energy market, watching where the money actually goes on its way to the meter. He's now building the AI infrastructure to strip those middlemen out of the chain, with Tem already transacting over £1 billion a year across thousands of UK businesses, backed by a fresh Series B to fund expansion into Texas and Australia.They cover:
- Why up to 30% of a business energy bill can go to trading desks, balancing costs and wholesale fees layered behind the supplier.
- How forward market contracts fix energy prices for months or years and why "shape matching" between generators and buyers creates a shadow market worth billions.
- The P442 grid charging exemption, and why a change this small took two years to push through.
- Why Joe believes Tem's AI agents could remove around 90% of labor costs in energy transactions, and why he sees that trade-off as necessary.
- Tem Energy's plan after its Series B - expanding into Texas and Australia before Europe and the case for energy AI becoming the UK's next trillion-dollar industry.

1 SEP 2026 · Battery storage went from an unproven bet to one of Europe's fastest-growing energy assets in a but the exceptional returns early investors saw have already faded as more batteries crowd the market. The real question today isn't whether a battery can make money, it's whether an optimiser can keep making money from it, market after market, year after year.In this conversation, Brecht Dierckx, Director of Physical Asset Trading & Optimisation at Centrica, joins Ed to unpack what actually separates a good battery optimiser from an average one, and why pricing, contracts and risk are becoming as important as trading itself.They cover:- Why the exceptional early returns 2017–2018 battery investors saw are gone for good, and what actually lets some optimisers keep repeating strong performance while others can't- How battery revenue has shifted over time — from grid-support services, to adjusting trades as markets move, to buying and selling across multiple markets at once — and why each edge shrinks as more batteries chase it- Why pricing a battery deal is nothing like pricing a financial instrument, and how modelling different future scenarios (rather than simple averages) reveals the real value of holding a diversified portfolio- What project developers are actually asking optimisers for now — performance guarantees, profit shares, protection from regulatory changes — and why some of those guarantees aren't realistically workable- Which European markets look most promising for battery growth next, and how emerging grid restrictions could shape how much value new assets are able to captureWant to know how flexible connection agreements or grid restrictions are changing your battery's revenue forecast? https://modoenergy.com/product/ko?utm_source=podcast&utm_medium=podcast_apps&utm_campaign=brecht_dierckx&utm_content=ko_signupChapters:0:00 – Battery Storage Returns Are Saturating1:04 – Battery Optimisation Operational Excellence2:22 – Repeatable Battery Storage Returns5:43 – Ancillary Services Revenue Saturation8:14 – Battery Optimiser Performance Benchmarks10:08 – Small Vs Large Battery Trading Teams14:25 – AI In Energy Trading16:29 – Autonomous AI Battery Trading Risks18:40 – Extreme Weather Impact On Energy Trading21:49 – Best European Battery Storage Markets24:13 – Battery Storage Toll Pricing28:59 – Battery Portfolio Diversification Strategy31:36 – Flexible Connection Agreements Explained35:51 – Battery Storage Investment Guarantees38:30 – Battery Storage And Grid Transmission

25 AUG 2026 · This summer, Britain recorded its first ever four consecutive months of 35°C+ heat and according to the Climate Change Committee, the UK isn't ready for it, physically or emotionally. As political pressure mounts in the net zero debate over whether Britain should slow its climate transition, the CCC's chief executive makes the case that affordability and climate action are the same fight, not competing priorities. Ed sits down with Emma Pinchbeck, Chief Executive of the Climate Change Committee (CCC), to find out what preparing for a hotter Britain actually looks like, and why extreme heat has quietly overtaken flooding as the institution's top adaptation concern.They cover:
- Why extreme heat is now the CCC's top adaptation priority, with up to 92% of UK homes at risk of overheating by 2050.
- How solar and battery storage naturally track cooling demand, and why that strengthens the case for air conditioning becoming standard in UK homes.
- Emma’s case for accelerating rather than easing off decarbonisation, including data showing EV- and solar-equipped homes can save up to £1,900 a year on energy costs.
- Why UK electricity is priced roughly 4x higher than gas, well above the 2:1 ratio in countries that have successfully rolled out heat pumps.
- Why Emma argues cost-of-living and climate policy are "the same question," not competing priorities.

18 AUG 2026 · Poland has cut coal's share of power generation from 95% to roughly 55% in a decade, with renewables generating over 30% of the country's power last year. That mismatch is already producing negative prices and turning battery storage into one of the country's biggest investment opportunities.Ed is joined by Tomasz Sęk, Founder and COO of R.Power Renewables, which holds a 1.7GW / 6.3GWh capacity-market-secured storage portfolio, one of the largest in Poland, to unpack how the country's power market is transforming.They cover:- Why coal's inflexibility, not its shrinking market share, is now Poland's biggest driver of negative prices and battery arbitrage.- How Poland's capacity market is evolving as de-rating factors and CapEx fall together, and what that means for the next wave of battery investment.- Why R.Power blends floor-plus-profit-share deals — including its new Axpo agreement — with full-toll contracts to balance risk and upside- How solar PPAs are evolving into Hybrid PPAs, as corporates like Amazon and Cisco look for more flexible, peak-shifted power- How R.Power plans to bring its 1.7GW / 6.3GWh capacity-market-secured portfolio online within 18–24 months, and what's setting the paceWant to go deeper on the Polish power market?
