Accelerating the sustainable energy transition

Batteries in electric vehicles and other e-mobility applications are subject to stringent requirements, and the batteries are rapidly replaced when they no longer meet the standards. Before being recycled, Octave aims to give a new purpose to these batteries, by transforming them from e-mobility batteries into a source of flexible energy that can contribute to the stability of the grid.


Wind and solar power are intermittent by nature. Octave copes with this variability by storing the electricity whenever the wind is blowing and the sun is shining, and by restituting it when there is a shortage.


The energy bill represents a significant share of the overhead costs. Octave helps to reduce the bill by lowering the imbalance costs directly or indirectly paid by your company.


The future of e-mobility will shape our cities, but the sustainability of the batteries is often questioned. Octave engages in a circular economy by giving a second life to the used batteries.


The energy sector is witnessning a fundamental revolution, driven by digitalisation and disruptive technologies. Octave uses advanced analytics and machine learning techniques to detect the optimal time to charge and discharge the battery fleet.

Our Daily Report

By capturing arbitrage opportunities on the imbalance tariffs, the batteries contribute to grid stability by storing electricity when there is unanticipated excess supply —e.g. when there is more renewable production or less consumption than forecasted— and by restituting it to the grid when there is a shortage. Our daily report gives an overview of the battery cycles performed yesterday.


The dashboard gives a real-time overview of the current state of the Belgian power system. Octave processes these data in order to predict the future state of the system imbalance and to control to the battery fleet accordingly.
