Innovation in energy-system modelling

What does
the future hold?

Terajoule builds more than models: we build adaptable energy ecosystems that connect infrastructure, economics and policy.

Research & innovation

Energy transition planning needs a connected system view.

We study multi-dimensional energy systems across carriers, sectors, geographies and climates. Our work turns complexity into order for the people planning infrastructure, investment and policy.

Energy modelling

Connected models spanning energy carriers, sectors, nodes and infrastructure.

Capacity planning

Plan generation, storage, networks and flexibility against the demand the system has to serve.

AI engineering

AI tools that help teams build, check and understand complex energy models.

The Joule Model

Europe’s energy system,
modelled together.

Explore how capacity, demand, weather, networks and technology choices interact across Europe’s connected energy system.
