Power System Engineering
Independent technical consultancy for renewable energy, battery storage and commercial power systems.
Supporting DNO applications, grid compliance, PowerFactory RMS studies, PSCAD EMT analysis and technically defensible reports for successful project development.
Grid connection evidence built around real engineering studies.
Modern Connections Need More Than Basic Paperwork
As UK electricity networks continue to evolve, connection applications increasingly require detailed modelling, technical studies and supporting evidence. Renewable and inverter-based technologies often demand a higher level of engineering analysis to demonstrate compliance, stability and network compatibility.
Detailed Modelling Requirements
DNOs may require accurate network models, RMS studies and supporting technical evidence before connection approval.
Compliance Evidence
G99/2 Type B, C and D projects often need clear documentation proving performance, protection and grid-code compliance.
Inverter-Based Technologies
Solar PV, BESS and modern converter-based systems can require deeper analysis such as FRT, harmonic and EMT studies.
RMS & EMT Studies for Grid Confidence
To support modern renewable and inverter-based connections, Save Electricity Ltd uses PowerFactory and PSCAD to provide detailed modelling, compliance evidence and technical support for successful DNO engagement.
PowerFactory RMS Studies
RMS-based studies for network performance, compliance evidence and technical reports required for DNO connection support.
