What do we do?

Electricity Saving

Power Quality Saving BV (PQS) is a company located in the Netherlands and active in the North of Europe. We are selling, installing and commissioning patented Power Optimizer technology from Energia Europa (Italy) for saving electrical energy by improving the energy efficiency in the network and its consumers. Regardless of the investments already done PQS will help you to reduce your consumption, improve the lifetime of your assets and reduce downtimes caused by micro interruptions and poor Power Quality.

Take the following step into the energy transition and towards a more sustainable world by investing in energy efficiency with a competitive payback period.

Learn how we save

Energy Saving

By improving your power quality with a simple installation of the patented E-Power and EP-Mini systems. The systems are installed after your electricity transformer and improve the power quality which leads to an improved energy efficiency in your company.

The increase in energy efficiency (3-8%) depends on the installed base. If you provide us with key figures, we can estimate the costs and an energy saving percentage. If the business case is positive, we can perform a survey on site to improve the accuracy of the expected saving. The saving after the site survey is a guaranteed saving.

Key benefits

  • Energy saving between 3% to 8% on total consumption
  • Payback period between 3-8 years
  • Guaranteed, proven and verifiable savings
  • Over 1000 installations in Europe in various businesses
  • Scalable solution for optimal balance between investment and returns
  • Maintenance of installation safety through certificate of short-circuit safety

Where applicable

The systems are installed in various types of businesses
(see also our References):

extra support


With subsidies we can further improve the investment payback period.
We can help you find the available subsidies to further improve on the payback time of the E-Power investment.

The Netherlands

In the Netherlands for the PQS E-Power Power Optimizer technology the 'Energie Investerings Aftrek' or EIA is applicable when the ROI is above 5 years.


In Germany our technology can be used to acquire the 'BAFA Energieeffizienz Modul 3' subsidy. PQS will of course help you to put in the request for this subsidy.

The first step is to determine if a Business Case can be made. Based on electricity consumption data, annual consumption in kWh or MWh, peak load and cost per kWh a Pre-Calculation is made by PQS.

Site Survey

If based on the pre-calculation a positive Business Case can be made a detailed site survey is done by one of our experts. Goal of the site survey is to make measurements of the incoming Power Quality on each transformer, list the electrical loads so a feasibility study can be made.

Feasibility Study

The feasibility study is transferred to a Validation Report with scope of electrical savings with economic implications. Part of the Validation Report is the calculation of the Return of Investment (ROI). Return On Capital Employed (ROCE) and a guaranteed savings percentage of the system.

Design, Quotation & Order

After order a detail design and engineering of the installation of the E-Power system is made.

After approval the installation is started.

Installation & Commissioning

Together with our installation partner the E-Power system is installed. After installation the system will be commissioned by one of our systems specialists to ensure a care-free operation of the E-Power system.

Energy Efficiency Report

Using a scientifically checked measurement protocol and calculation the actual saving of the system is measured by switching the E-Power on and off without interrupting the energy flow. The results of the performance test are presented in the Energy Efficiency Report.

Monitoring & Reporting

The integrated measurement system and datalogger allows to immediately check and monitor the performance of the E-Power. It is also possible to recieve reports of measured data, saving figures and status of the system.
This will contribute to meet the ISO14001 and ISO90001 requirements.
