Germany’s Battery Deadline Comes Before the Grid Rules Do - Kyon Energy
3 november 2026 · 31 min
Germany’s battery storage pipeline looks like a “tsunami” on paper, but grid connection requests say little about how many projects actually get built. The ones that do face a hard deadline: reach final investment decision this year to keep the grid fee exemption, while the rules that replace it are still being finalised. Lees meer
Ed Porter is joined by Marie-Sophie Braun, Head of Markets and Regulatory Affairs at Kyon Energy, a German battery storage developer that now operates its own assets as an independent flexibility provider, to unpack how investment decisions get made when the rules are still moving.
They cover:
- Why the flood of grid connection requests says little about how much BESS Germany will build, and why the storage industry has no incentive to overbuild.
- How Kyon is approaching final investment decisions to keep the grid fee exemption for assets live before August 2029, why seven months is tight for an infrastructure investment, and why Marie still calls the new grid fee regime a fair compromise.
- What separates a flexible connection agreement a bank will finance from one that stalls projects, and why uncompensated curtailment needs a clear cap.
- Why Kyon splits comparable assets across different route-to-market providers, and what it wants to see from optimisers beyond the pitch deck.
- Why Germany pushes co-located storage and renewables while applying different grid rules to each, and what a split into price zones would mean for flexibility.
Want to see how German batteries are performing? Ko, Modo Energy's AI analyst, can answer questions on German BESS revenues, grid fees and the build-out.

Inside Great Britain’s First Battery Revenue Swap - SSE & Statkraft
27 oktober 2026 · 34 min
What if a battery storage project could lock in its revenue before it's earned it? SSE and Statkraft have done just that with a battery revenue swap: SSE gave up the ups and downs of battery income for a fixed price, Statkraft took them on, and both energy companies came out with less risk. Lees meer
On this episode of Transmission, Ed Porter is joined by Josh Brown, Origination Team Manager at SSE, and Cian O'Duffy, Energy Markets Quantitative Analyst at Statkraft, two people behind the deal, to explain how energy trading deals like this work and who could do one next.
They cover:
- How a battery revenue swap is set up, and why it needs far less paperwork than a wind farm PPA.
- Whether a swap changes how you run your battery, and what basis risk means for owners.
- How wind farms, solar farms and energy suppliers could use battery revenues to manage risk.
- Why big businesses might buy a virtual battery instead of building their own.
- What's next for battery storage deals, plus two contrarian views on CfDs and battery revenues.

Battery Storage in Germany: A Grid Operator’s View - 50Hertz
20 oktober 2026 · 36 min
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. Lees meer
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?

Financing Merchant Batteries When Contracts Run Out - Aquila Clean Energy
13 oktober 2026 · 36 min
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. Lees meer
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.

How Battery Swaps Unlock Finance - Miranda Energy
6 oktober 2026 · 39 min
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. Lees meer
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.

Poland's Battery Market is Skipping the Pilot Phase - Entrix
29 september 2026 · 34 min
Poland's battery storage market is skipping the pilot phase, with its first projects starting at 200MW, a size it took Germany five years to reach. And because of the way Poland runs its grid, two identical batteries in different locations can earn very different amounts. With over 2GW of batteries expected on the grid by 2028, the market is about to change fast. Lees meer
Ed Porter is joined by Aleksandra Radwańska, Country Lead Poland at Entrix, and Jan Kłoczko at Entrix, to unpack what it takes to optimise batteries in a market scaling this fast.
They cover:
How two identical batteries in different parts of Poland can earn very different amounts, and why each needs its own scorecard.
Why getting a new battery approved to support Poland's grid can take up to two years, while everyone is still learning the rules.
How over 2GW of batteries expected by 2028, in a country that peaks at around 25GW, will change the way power is traded in Poland.
What battery owners are choosing between: guaranteed-income deals that help secure loans, or betting on the market.
Why Poland's single national electricity price is coming under strain as the grid gets more congested.

The Future Of The Gas Network - Cadent
22 september 2026 · 36 min
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. Lees meer
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.

What's Really Holding The Grid Together - Fluence
15 september 2026 · 1 uur 3 min
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? Lees meer
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 in

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? Lees meer
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.

What Happens When Every Battery Market Gets Crowded? - Centrica Energy
1 september 2026 · 43 min
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. Lees meer
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 capture

Can Britain Afford to Slow Down on Net Zero? - The CCC
25 augustus 2026 · 39 min
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. Lees meer
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 one of the CCC's top adaptation recommendations, 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.

How Poland Is Building a Renewable Power System - R.Power Renewables
18 augustus 2026 · 30 min
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. Lees meer
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 pace

Is Britain's Grid Ready for Clean Power 2030? - Roadnight Taylor
11 augustus 2026 · 44 min
Most people assume Great Britain's grid connection queue works on a first come, first served basis. It doesn't - and that misconception is costing developers time and money. Connections reform was meant to bring clarity to the queue, but projects that were declared protected and pushed to the front are still missing their connection dates, and new contract disputes are now stalling projects that should already be moving. It all comes down to what actually gets built — and whether Britain can get anywhere close to Clean Power 2030. Lees meer
Catherine Cleary, Specialist Connections Engineer at Roadnight Taylor and a returning Transmission guest, joins Ed Porter to unpack what's really determining who connects to the grid, and when.
They cover:
- Why the grid connection queue isn't ordered by application date and how a 20MW battery project can end up waiting behind a nuclear power station for the same network reinforcements.
- Why gate two offers under TMO4+ are going out with technical errors, and why fixing something as small as a typo can take months once you're one of hundreds of affected projects.
- Why NESO's oversubscription numbers might be the wrong problem to solve, and what bay sharing could do instead.
- Why data centres and other demand customers are pushing for independent transmission owner (ITO) status, and what Ofgem's latest signal means for future connections.
- Catherine's contrarian take after 15 years in the industry: why Britain might be about to build too much grid, not too little.

Why Batteries Are Changing Faster Than the Industry Expected - Marek Kubik
4 augustus 2026 · 43 min
Battery storage costs have fallen by two-thirds since 2022 and the cell chemistry currently dominates the grid barely existed at scale five years ago, and the same disruption could be about to happen again. Meanwhile, the supplier market is fragmenting rather than consolidating and the biggest names today aren't guaranteed to stay on top. Lees meer
Marek Kubik has watched these shifts happen from inside the industry since the early days. He joins Ed to explain why the balance of power in battery storage keeps changing, and what's coming next.
They cover
Why battery storage costs have fallen two-thirds since 2022 - and why that could be about to reverse.
The real reason CATL's battery market share has dropped from 32% to 20%.
Why sodium-ion batteries could repeat LFP's rapid takeover of grid-scale storage.
How battery container design is changing again, from bigger cells to taller stacks.
The battery duration limit everyone assumed was fixed - until 16-18 hour systems broke it.

What Happens When The State Take Risks Private Capital Won't? - GB Energy
28 juli 2026 · 45 min
GB Energy's £1 million solar investment freed up savings a Hull hospital had left on the table for years. It's an example of what can happen when a state-backed investor takes risks the market won't. Lees meer
GB Energy calls itself an activist investor, built to put public money behind the frontiers where private capital moves too slowly: deepwater wind, long duration storage, public sector solar. The interesting question now is how far this model can scale, and how well it keeps sharing that risk with private capital as it grows.
Dan McGrail, CEO of Great British Energy, joins Ed Porter to explain how Britain's state-owned energy company decides where to invest, and why it's taking on the risks private money won't take first.
They cover:
- Why the "activist investor" model can justify riskier bets than pure-return investors would take - and where that logic stops making sense
- How to identify an investment "frontier": the areas of high ambition where private capital isn't moving fast enough to hit national targets
- What a queue of 50GW+ in unsolicited co-investment enquiries reveals about investor appetite for state-backed risk-sharing
- Why community-owned local energy can outperform national schemes on economic impact - one Orkney turbine now funds housing, buses and insulation
- Why chasing niche global market share, not local content quotas, may be the smarter industrial strategy for competing with China

Why Would A German Battery Agree To Switch Off? - Green Flexbility
21 juli 2026 · 38 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. Lees meer
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 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 juli 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. Lees meer
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
7 juli 2026 · 44 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. Lees meer
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 juni 2026 · 38 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. Lees meer
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 juni 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. Lees meer
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.

Grid Fees and Saturation: Germany's Battery Outlook - Modo Energy
16 juni 2026 · 47 min
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. Lees meer
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 German BESS returns.
They cover:
Why German battery saturation is closer than the market thinks - FCR is already saturated, with aFRR close behind.
• Why German battery revenues near €200,000/MW/year for a two-hour system are more about timing than structure.
• What makes Germany's intraday market the most liquid in Europe and the €1,000+/MWh spikes batteries feed on.
• How flexible connection agreements are quietly reshaping returns, from ramp rates to export caps.
• What German grid fees look like after the 2029 exemption and why dynamic fees are locational pricing through the back door.

How Battery Traders Actually Make Money - Statkraft
9 juni 2026 · 52 min
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 actually gets captured. Lees meer
In this episode of Transmission, Ed Porter sits down with Brian Lonn, Head of UK Flexibility at Statkraft, to break down how a multi-gigawatt battery optimisation desk actually trades batteries and the offtake structures it offers on top.
They cover:
How battery re-trading works in practice.
How Statkraft scaled its GB flex portfolio from 22MW of intraday-active battery volume to ~4.5GW under contract and why this scale is the precondition for offering offtake at all.
Why the battery optimisation market could consolidate and what that means for smaller optimisers and asset owners.
How battery floors, tolls, and day-ahead swaps differ in tenor and purpose, with a working £/MW ballpark for each on a 2-hour battery.
Brian's contrarian view on Clean Power 2030: why the real question for the GB power system is megawatt-hours, not megawatts.

Connections, Capacity & Clean Power: Britain's Grid Reform - NESO
2 juni 2026 · 54 min
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. Lees meer
Ed Porter is joined by Kayte O'Neill, Chief Operating Officer at the National Energy System Operator (NESO), for a wide-ranging conversation on the biggest changes in the GB power market: grid connections reform, the battery storage queue, zero-carbon grid operation, and the next wave of electricity market design.
They cover:
Connections reform and the UK grid queue — how NESO has cut the 800GW queue down to a deliverable pipeline and what Gate 2 means for developers over the next 12 months.
The battery storage connections queue and how NESO is thinking about attrition, bay sharing and co-location.
Zero-carbon operation of the GB grid and why gas plants still run on windy, sunny days (stability services, inertia, grid-forming inverters)
NESO's expanded whole-system role - strategic planning across electricity, gas and hydrogen, and the Strategic Spatial Energy Plan (SSEP)
Reformed National Pricing, data centre demand connections, AI in the control room, and the £40bn/year investment unlock at stake.

Where Capital Is Flowing in Spanish Renewables - nTeaser
26 mei 2026 · 25 min
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. Lees meer
Ed Porter sits down with Carmen Izquierdo Serrano, founder of nTeaser, the renewable energy marketplace where many of Spain's BESS, solar, and co-located deals are transacting, to unpack what those numbers actually mean for investors entering the Spanish power market and how the post-blackout urgency, and bottlenecks in financing and labour will shape who wins the next phase of Spain's energy transition
They cover:
Why Spanish solar ready-to-build prices have collapsed from €200,000 to €50,000 per megawatt while battery prices have climbed to ~€100,000 per megawatt in the space of three years
How the 30GW Spain BESS pipeline stacks up against the ~3.5GW expected to be operating by 2030, and why Carmen thinks that operating-asset forecast is conservative
Where the real bottleneck is for delivery - not developers or permits, but bank financing and the skilled labour needed to construct the projects
Why Italy's BESS market has slowed after the first MACSE auction while Spain has accelerated, and what that means for capital allocation across Southern Europe.
How buyer expectations on arbitrage revenues are likely to be cannibalised as more batteries enter the market, and which revenue streams banks will actually finance against

Where Capital Is Flowing in Spanish Renewables - nTeaser
26 mei 2026 · 25 min
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. Lees meer
Ed Porter sits down with Carmen Izquierdo Serrano, founder of nTeaser, the renewable energy marketplace where many of Spain's BESS, solar, and co-located deals are transacting, to unpack what those numbers actually mean for investors entering the Spanish power market and how the post-blackout urgency, and bottlenecks in financing and labour will shape who wins the next phase of Spain's energy transition

Clean Power 2030: Inside Mission Control with Chris Stark
19 mei 2026 · 56 min
Chris Stark is leading the UK's Clean Power 2030 mission. As Head of Mission Control at DESNZ, no one sees the constraint costs, grid bottlenecks and reform of National Pricing trade-offs more clearly. Lees meer
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 hit £1.7 billion, gas is being squeezed off the system, and the government has just rewritten the rules of the wholesale market.
Chris joins Ed Porter to break down what Mission Control is actually delivering, where flexibility and storage fit into the 2030 plan, and what Reformed National Pricing means for investors, generators and consumers.
They cover:
Why building UK transmission lines takes 8-10 years — and why bringing two projects forward by a year is worth £4bn to consumers.
Why the UK chose to build the grid and the generation simultaneously, and the risks that creates.
Why the strategic spatial energy plan is the biggest energy decision coming in the next 12 months and how it sets up a "build it once" network for the future.
The reform of National Pricing decision, what the wholesale CfD means in practice and how electricity is being de-linked from gas.
Why flexibility is the "forgotten third child" of the energy transition and how dunkelflaute, long-duration storage and household batteries fit into the 2030s system.
Chris's contrarian take on carbon pricing - why he thinks the Treasury's decision to remove the Carbon Price Support from gas signals carbon pricing is "coming down the list of things that matters.”
