Compliant Power Systems with EPS

Leveraging advanced software tools such as DigSILENT, ETAP, and PSCAD, we provide all grid and distribution code compliance studies for synchronous and non-synchronous power generation plants. Our studies consist of assessing your grid connections’ technical and operational viability while taking into account environmental effects and legal compliance. Overall, these thorough examinations ensure that your project runs well within the grid system. If non-compliance becomes apparent in your network, then we can propose design modifications or recommend strategies to resolve the issue, including supporting discussions with the system operator.
