Storage Moves from Niche to Grid-Critical Infrastructure

Global installations surpassed 100GW in 2025, with 158GW forecast for 2026. Yet connection queues, revenue uncertainty and regulatory fragmentation remain the primary barriers to deployment. As AI-driven demand and grid modernisation accelerate investment, this is the moment when storage transitions from renewable energy support to standalone critical infrastructure requiring its own commercial frameworks, financing structures and policy design.

Six Streams Addressing Storage's Most Critical Commercial Challenges

The 2027 programme features six dedicated streams: Security, Connect, Markets, Transact, Deliver and Demand, each tackling the most pressing questions around bankability, deployment speed and revenue certainty. From grid connection reform and international market comparisons to finance structures, procurement strategies and AI-driven power demand, the agenda covers the full commercial lifecycle of storage projects.

Protecting Critical Infrastructure

Navigating Grid Reform and Queue Design

Decode connection queue reform, network planning and market design changes reshaping deployment timelines across Europe, with direct insight from grid operators and regulators on FCA implementation and technical requirements.

Powering Data Centres and Industrial Loads

Understand how hyperscale data centres, AI infrastructure and industrial offtakers are driving storage demand beyond traditional renewable energy integration, exploring co-location partnership models, corporate PPA structures and grid connectivity solutions.

Structuring Finance and Offtake

Examine tolling agreements, revenue floors, M&A valuations and debt structures underpinning bankability in 2027, learning how investors are pricing merchant risk and which revenue-stacking models are securing non-recourse project finance.
