Accelerating the energy transition

We believe that it makes little sense to use virgin batteries for stationary energy storage. Battery packs that are considered end-of-life for e-mobility still have usable capacity in the majority of the cases. Octave wants to leverage this intrinsic potential and repurpose end-of-life batteries into a source of flexible energy that contributes to the stability of the grid.


Wind and solar power are intermittent by nature. Batteries can absorb this variability by rapidly storing or releasing the electricity whenever the grid needs it.


The energy bill represents a significant share of the overhead costs. Octave reduces your bill by optimizing your energy production and consumption.


E-mobility is booming, but there are concerns over the sustainability of lithium-ion batteries. Octave engages in a circular economy and hence lowers the overall carbon footprint of these batteries.


The energy sector is digitalizing rapidly. Octave uses advanced analytics and machine learning techniques to detect the optimal time to charge and discharge the battery.

Our technology

Octave's energy storage solution consists of both a hardware and software component: the physical stationary energy storage system that is composed of second-life batteries from electric vehicles; and the virtual battery cloud that closely monitors and optimally controls the battery cells throughout their entire lifespan.

The algorithm at work

The daily report below shows how our battery fleet captured yesterday's arbitrage opportunities on the imbalance market.

Our dashboard

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