Power System Studies

Power system studies ensure the safe, efficient and reliable operation of electrical networks that are essential to business. Reduced downtime and continuity of supply will save you time and money.


What are Power system Studies?

Power system studies offer peace of mind. The assessment of electrical networks by power systems engineers can help to obtain grid connection agreements, identify existing or potential problems and optimise performance. They are a requirement for most new connections to the electrical grid and are used to show the site can meet the performance criteria required by the connecting authority. An efficient electrical network and quick grid connection saves you money!

Power System Studies


Following data collection such as electrical design drawings, manufacturers’ datasheets and connection point characteristics, our power system engineers will model and analyse your network to assess your site against defined standards and recommendations relating to performance, safety and efficiency.

We then provide a professionally indemnified engineering report that outlines key findings and recommendations to address any highlighted issues.
