Battery Services

Monitoring

The Battery Cloud technology allows us to collect extensive data on each battery cell in the battery cabinet. Analytics running in the Battery Cloud make it possible to identify in advance which battery modules are at risk of degrading below 70% of their original capacity.

As part of the monitoring service, we will:

  • Perform continuous and remote monitoring of all individual battery cells;
  • Make these data available through a web based dashboard and report on the historical data and the high level status of the system;
  • Provide an ad-hoc report of the state of health per battery module on request of the client;
  • Inform the client when a specific battery module degrades below 70% of its original capacity.

Capacity Guarantee

As part of this service, we guarantee that the energy storage capacity of the Octave battery cabinet stays at minimum 70% of the original capacity for a period of 10 years at a fixed fee.

The service covers the replacement of degraded battery modules via predictive maintenance. We or our maintenance partner will come on site to replace the degraded battery modules by healthy battery modules. The purchasing cost of the modules, the preparation of the module by charging it to the right voltage and transportation of the modules are included in the fee for the Capacity Guarantee.

Contracting the Battery Monitoring service is a prerequisite to enjoy the Capacity Guarantee.

Optimal Control

As part of this service, we optimize the charging and discharging of the battery energy storage system throughout the operational life of the battery 24/7. This way, we can make sure that your System delivers maximum value.

Optimization of self-consumption is included in our default offer for this service. The battery is charged when there is an excess of solar production and discharged to avoid consumption from the grid.

In addition, the following applications are available as an option:

  • Peak shaving: lowering the peak consumption or production profile of the site. This application is combined with the optimization of self-consumption.
  • Grid-frequency control services: charging of the battery to support the overall balance of the electricity grid and e.g. avoid a blackout. In this application, the battery will be partly controlled by the grid operator (Elia). For this service, we will transfer to the client a share of the revenues received by the aggregator from the grid operator. The payment is done through self-billing on a quarterly basis.
