Innovation in energy-system modelling

What does
the future hold?

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

Research & innovation

The transition is not one problem. It is a connected system.

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

Adequacy, flexibility and infrastructure needs translated into decision-ready evidence.

AI engineering

Governed assistants that help build, check, explain and interrogate complex energy models.

The Joule Model

One model.
Many carriers.

A cross-sectoral planning environment for testing capacity, adequacy, flexibility and flows across Europe’s interconnected energy system.
