The FREE Energy Summit is a focused, in-person event dedicated to real-world projects at the intersection of Bitcoin mining and energy systems.
Now in its second edition, the event centres on concrete, live initiatives – presented by the people directly responsible for them – offering technical, economic and operational insight rather than theory.
The FREE Energy Summit brings together the people reshaping how Europe thinks about energy — and those ready to act on it. Energy producers, grid operators, renewable developers, engineers, infrastructure professionals, policymakers and investors gather under one roof to hear directly from the teams operating Bitcoin mining as a live energy management tool across the continent.
Europe’s grids are under pressure. The April 2025 Iberian blackout was a signal, not an anomaly. As renewable capacity grows faster than grids can absorb it, curtailment is quietly eroding the economics of new projects. The summit puts a working answer on the table — one already deployed across Europe, backed by five-plus years of operational data.
Speakers present real projects: Bitcoin mining integrated as a flexible, interruptible load; surplus renewable energy converted into heat and revenue in greenhouses, warehouses and homes; France’s electricity strategy doubling global Bitcoin hashrate — and what that signals for grid planning across the continent.
Attendees hear the numbers, the integration challenges and the performance results from the engineers and developers who built these systems from the ground up. Not theory. Not projections. Operational experience from people with skin in the game.
For anyone working at the intersection of energy and infrastructure, this is where the conversation is already happening — and where the next moves are being made.
