    Connections, Capacity & Clean Power: Britain's Grid Reform - NESO

    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 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.Ask Ko, Modo Energy's AI energy analyst, your questions on UK grid operations and BESS markets: Sign up here Transcript available here Hosted by Ed Porter, Director EMEA & APAC at Modo Energy.

    Where Capital Is Flowing in Spanish Renewables - nTeaser

    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 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 yearsHow 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 conservativeWhere the real bottleneck is for delivery - not developers or permits, but bank financing and the skilled labour needed to construct the projectsWhy 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 againstWant to go deeper on Spanish BESS revenues?

    Clean Power 2030: Inside Mission Control with Chris Stark

    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 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.”Want to model how Clean Power 2030, REMA and the wholesale CFD reshape GB power prices?

    Why Germany's Battery Storage Market Is Harder Than It Looks - Terralayr

    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 reality of building Germany battery storage at scale, the regulatory tension around grid fees, and the contrarian view that Germany's flexibility market is structurally larger than most forecasts suggest. They cover: - Why operating Germany battery storage is harder than capital alone can solve. - Why Germany's TSOs are positive on BESS, why DSOs are nervous and what regulators need to fix. - What the Bundesnetzagentur grid-fee review means for the BESS exemption running to August 2029. - How splitting merchant capacity across multiple optimisers outperforms single-optimiser tolls. - Why flexibility revenues are convex, dominated by tail events, and structurally larger than forecasts predict.
