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!


Following data collection such as electrical design drawings, manufacturers’ data sheets and connection point characteristics, our 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.
