Penalties on the bill
Above a certain threshold, the reactive energy you draw is billed: an expense that produces nothing.
Our answer
A capacitor bank sized to bring the power factor back to the right level.

The challenges
What is at stake
Fixed or automatic capacitor banks to improve the power factor: fewer penalties on the electricity bill and less stress on cables and transformers.
An overloaded installation
Reactive current needlessly loads transformers and cables, which heat up and reach their limits.
Our answer
Less current in the installation: capacity freed up for new equipment.
Loads that vary
Motors, air conditioning and processes do not run all the time: fixed compensation cannot keep up.
Our answer
Automatic stepped banks driven by a reactive power controller.
Harmonics
Drives and electronics create harmonics that can damage poorly chosen capacitors.
Our answer
Harmonic measurement before the design and detuned banks where necessary.
Architecture
An architecture designed in layers
The capacitor bank supplies on site the reactive energy your motors need: the grid no longer has to carry it, and you no longer have to pay for it.
Every installation is delivered tested, labelled and documented, for simple operation and maintenance.
- Layer 01
Measurements
Recording of power factor, power and harmonics over several days.
- Layer 02
Controller
It measures continuously and switches in the steps required.
- Layer 03
Capacitor steps
Capacitors in steps, with suitable contactors and protection.
- Layer 04
Filtering
Detuning reactors where the supply is polluted.
- Layer 05
Main switchboard connection
A protected connection to the main switchboard, as close to the loads as possible.

Maintenance & 24/7 support
This system can be covered by a preventive and corrective maintenance contract, with priority response on critical sites.
See the plansHow do I know if I pay for reactive energy?
It appears on your electricity bill. Send us your latest bills: we will tell you the amount at stake and the possible savings.
How quickly does the installation pay for itself?
Often within a few months to two years, depending on the penalties paid. We estimate this before any commitment.
Is a fixed bank enough?
For stable loads, yes. If consumption varies during the day, an automatic bank avoids over-compensation.
