Solar PPC Puttershoek: Reactive Power Optimization

Integrating Renewable Energy and Advanced Control Techniques for Sustainable and Balanced Power Consumption

This project tackles an important issue that the Cosun beet factory is facing: antiquated equipment that uses an excessive amount of reactive current from the grid. The project shows how cutting-edge technology and environmentally friendly methods can be used to achieve a more effective and balanced power consumption profile.


September 2022.





One of the main problems affecting the project is the age of the machinery in the Cosun beet factory. Since the factory’s machines are quite old, they require a lot of reactive current from the grid. Reactive current is a type of electric current that does not do any useful work, but is necessary for the functioning of certain equipment.

Excessive reactive power consumption strains the electrical infrastructure and can lead to inefficiencies in power distribution. It may result in greater energy expenditures as well as poor power quality.



The project methodology involves leveraging Spectral’s experience and technology to address excessive reactive power consumption at the Cosun beet factory. Spectral analyzes reactive power at the grid connection point and controls reactive power generation at the factory’s solar park. The project team balances and compensates for the factory’s reactive power usage by monitoring and modifying reactive power levels in real time. This method optimizes the efficient use of electrical resources, minimizes grid strain, and improves power quality. The project exhibits a dedication to sophisticated technology and the integration of renewable energy sources in order to produce a more sustainable and balanced power consumption profile.



Spectral has achieved a power factor of 1 at the grid connection by managing the solar park’s reactive power generation. This eliminates excess reactive power, increases energy efficiency, reduces load on the grid, and improves power quality. The project’s success in integrating renewable energy with state-of-the-art control methods has produced an electrical system that is both sustainable and effective.
