Energy Tech Summit

Event details

Date:
23rd June 2025
Time:
09:00
Location:
Evolution London, Battersea Park

The Octopus Energy Tech Summit is coming to London Climate Action Week for the first time, kicking off the week and leading the conversation on how technology can drive the clean energy transition.

We will explore how technologies like AI, batteries, EVs, and heat pumps are reshaping energy from generation right through to end use in our homes, and how the UK can show leadership at this moment to drive faster change. The Summit will delve into the opportunities and challenges of rapidly evolving tech, the implications for policy decisions, and the global cooperation and interdependence required to make the clean energy transition a reality.

In a world that can feel increasingly divided and progress hard, this must-attend Summit aims to show that technology is a force for unity, helping to drive down costs, increase energy security, deliver a cleaner energy system, and provide the basis for a stable climate for everyone.
