Maximising the value of every unit of energy.

The energy system is changing fast. As renewable generation and electrification spread, flexibility becomes more valuable, and assets such as home batteries, commercial and industrial batteries, electric vehicles and grid-scale storage can all help balance supply and demand. Capturing that value takes direct market access, sophisticated forecasting and real-time optimisation.

Joulen provides all three. We trade directly in energy markets and use our platform to forecast tradable volumes and find the strongest opportunity in any given period, so flexible assets earn more than they otherwise would. We do this with installers, energy retailers and OEMs, who gain a stronger customer proposition and a new revenue stream, while asset owners see better returns and the grid gets more flexibility.

Our mission

To maximise the value of renewable and flexible energy assets through intelligent software, helping investors achieve stronger returns while enabling a more efficient, resilient, and sustainable energy system.

Our ambition

To become a globally recognised provider of flexibility services across behind-the-meter and grid-scale assets, scaling traded volumes, revenues, and market presence through strong partner channels, direct market trading, and international expansion.
