Agenda

Owners and operators of Europe's largest fleets will provide a candid assessment of running fleets of batteries as portfolios mature.

•             Compare where operational returns are holding up and where cannibalisation is biting and find out what asset owners are putting in place to reduce risk

•             What separates a top 10 asset (highly available, faults fixed within hours) from the rest of the fleet?

•             Hear how pension fund and institutional project ownership is changing operational decision-making

•             As portfolios grow from three sites to ten and beyond, which capabilities should move in-house and which are better bought?

Contracted structures now dominate new financings, yet merchant assets continue to operate, and in some markets outperform, across Europe. Delegates vote on the motion, that standalone merchant BESS is no longer financeable at scale in Europe, via a poll before the session opens. The moderator will then lead two senior practitioners on opposing sides of the question through a fireside conversation on comparative revenue performance, executed contract terms and the conditions under which each model remains financeable, before the closing vote reveals whether the room has moved.

•             Benchmark how merchant assets performed against tolled and floored peers across the UK, Germany and Benelux in 2026

•             Get specific on executed deal terms: tenors, availability clauses, cycle limits, degradation provisions and who carries which risk

•             Are floor plus upside structures leaving owners enough upside, or is value quietly leaking to offtakers?

•             With GW scale projects too large to run merchant, whose balance sheet steps in, and at what price?

•             Hear how lenders weigh contracted share, tenor and counterparty quality when setting debt terms

A market update on the round two results, followed by a panel on what running a heavily contracted asset demands and which lessons transfer to other markets adopting structured procurement.

•             Get the numbers first: pricing, winners and the headroom left for private players and tolls outside the auction

•             Hear what MACSE compliance demands operationally, from EMS redundancy to delivery penalties and availability engineering

•             Does an auction dominated by one large winner leave a functioning market for everyone else?

•             Which parts of the Terna model could other European TSOs adopt, and which should they avoid?

We look at where the next wave of operational assets will be running by 2028. The room votes on the most likely outcomes.

•             Understand what is driving investor interest in more developing (for example, Poland and Romania) as well as the more developed (for example UK and Germany) BESS markets, from capacity contracts, grid stability services to generation growth

•             Compare Poland's long tenor capacity contracts with Western European revenue models

•             Spain, the Nordics and the next entrants: which market builds an operational fleet fastest?

•             Which prediction will the room back, and who will be proved right next year?

Hosted tables, each led by a practitioner and reporting key takeaways back to the room.

•            Candidate topics: benchmarking your optimiser, degradation data for warranty claims, cyber readiness, insurance and ageing fleets, co-location retrofit economics, tolling contract clauses, end of life planning, fire safety and community engagement

•            3-4 tables mixing commercial, technical and market themes

This session compares what is changing, market by market, and what it does to operating revenues.

•            Quantify the revenue impact of flexible connection agreements as they spread from the Netherlands into Germany and Italy

•            Get ahead of queue reform: UK NESO gates, maturity-based processes and the clawback of speculative capacity expected in Italy from 2027

•            If accepting curtailment gets you connected years earlier, how much ramping restriction should an operator trade?

•            Assess the stability services opening up to batteries, from synthetic inertia to reactive power, and why Iberia is moving first

•            How are owners pricing Germany's grid fee changes from 2029 into operating plans now?

How do owners know their optimiser is delivering, and how do the best optimisers prove it? This session examines the benchmarks, reporting standards and governance frameworks emerging across Europe’s operating fleets, and the contract structures that align both sides on measuring performance fairly.

•            Take away practical approaches to benchmarking optimiser performance against the market opportunity, not just against budget

•            When revenues look good against plan, how do you spot the underperformance a buoyant market is masking?

•            Hear how multi-optimiser structures and digital twins create competitive benchmarks on a single asset

•            Is underperformance the asset, the optimiser or the market, and who is accountable for finding out?
