EPESYS provides the most focused and systematic approach for Electrical Network Studies. Power system planning, design, operation, and expansion require careful studies to evaluate the system design, performance, safety, efficiency, reliability, and economics under various complex scenarios.
Network studies help to identify and bridge the potential deficiencies of the proposed system. We bring years of field experience and knowledge of numerous power regions and independent system operators.
