Day 1 - Plenary
Keynote Panel: Developing a Bankable German BESS Project in 2027 and Beyond
Germany’s storage market is widely viewed as the most liquid and flexible market in Europe. However, big policy hurdles and uncertainties remain, leaving an overwhelming development landscape. Grid congestion, grid connection fee reform, curtailment constraints and more.
- How is the German BESS business case evolving as deployment accelerates and market participation becomes more competitive?
- How can the industry scale the German BESS market without harming revenue access?
- What assumptions around revenues, asset performance, and market design are critical to project bankability?
- How can developers finance future-proof projects against changing regulations, market conditions, and revenue opportunities?
- Implications of a capacity market on German development and the criticality of the de-rating methodology

Flexibility Purchase Agreements: The New Golden Standard for Bankability
| 2025 was a record year for Flexibility Purchase Agreements (FPAs). As German BESS projects scale without subsidies, fixed-price FPAs are emerging as a key tool to secure revenues and unlock debt. But are they truly the “new PPA,” and how should risk be allocated between asset owners and offtakers? |
- Does the German market already exhibit clarity and standardisation for flexibility offtake contracting?
- Which offtake models are most prevalent in the German market and why?
- Do all fixed revenue offtakes carry equal value from a lender perspective?
- How are tolling arrangements pricing in longer duration and higher level of grid constraints?
- How can flexibility offtake agreements evolve to further unlock leverage for German assets

Asset Management
The Asset Manager as AI Orchestrator: The Future of BESS Operations
As BESS portfolios grow in scale and complexity, asset managers are being asked to make faster, better-informed decisions across performance, availability, maintenance, warranties, commercial impact, and stakeholder reporting. AI is opening new possibilities for how this work gets done, from faster analysis and reporting to more proactive decision support.
This session explores how AI could transform BESS asset management from reactive, manual coordination into AI-supported operational intelligence. It will look at where AI can add practical value today, what needs to be solved before it can become truly operational, and how the role of the asset manager may evolve as specialist AI assistants become part of the daily operating model.
- Understand how AI could reshape the role of the BESS asset manager as portfolios become larger and more complex.
- Explore where AI can create practical value across asset management workflows, from analysis and reporting to prioritization and decision support.
- Learn what needs to be solved for AI to move from ad hoc assistance to secure, connected operational use.
- See how specialist AI assistants could support workflows such as performance monitoring, maintenance, reporting, warranty management, and stakeholder communication.
- Consider why the future of asset management is not autonomous decision-making, but human-led operational intelligence supported by AI.
Live Interview: Lessons from Bollingstedt
Modelling BESS Revenue Under Germany's Flexible Connection Agreements
- Germany's FCAs are reshaping how storage projects get built and financed, with four main types used to manage congestion: time-based/scheduled constraints, event-based constraints, ramp rate and ancillary service restrictions, and wholesale/order book schedule freezes
- Uses Gridcog modelling data to show the real revenue impact of these constraints on a standalone 50MW/2hr BESS and a co-located BESS plus solar project, comparing scenarios across constraint types and severities (e.g. 1%, 5% and 10% ramp limits, plus scheduled and event-based restrictions)
- Aimed at developers, IPPs, investors and asset managers who need bankable numbers for BESS projects constrained by FCAs
- Grid congestion and FCAs aren’t unique to Germany: dynamic operating envelopes in Australia and active network management in GB show how other markets are solving the same underlying problem in different ways

Optimising for Value, Not Just Performance
- The biggest revenues are earned on a handful of critical days – being available when market opportunities peak matters more than marginal optimisation gains every other day.
- Availability is a revenue strategy – maintenance, degradation management, and operational resilience should be designed around capturing the most valuable market windows.
- The best optimiser isn't the one that wins every day – it's the one that consistently positions the asset to perform when the stakes, spreads, and revenues are highest.
