NnG is an offshore wind farm located 15.5 km off the Fife coast, jointly owned by EDF Renewables and ESB. The project has the potential to generate 450MW of renewable energy, which is enough power to supply around 375,000 Scottish homes* and will offset over 400,000 tonnes of CO2 emissions each year.
Being part of this project, WSP is contributing to reducing GHG emissions across the UK Power Network by reducing CO2 emissions from renewable energy sources. Projects of this type play a significant part in the UK government strategy to achieve Net Zero by 2050.
Our Quality Services and Power Systems teams have supported the NnG project during the planning and construction phases providing advisory and consultancy services.
WSP quality professionals are embedded within the NnG team and provide specialist quality advice to support the manufacturing inspections of critical assets. Our role extends across a number of special processes, including; welding, non-destructive testing, coatings and electrical testing. It covers offshore structures, platforms, export and array cables.
Our Power Systems team completed a complex task to investigate and verify the overvoltages expected to occur under worst-case conditions. This ensures they are within the limits of the insulation levels of the selected equipment for the as-built design, based on manufacturer’s cable, surge arrester, circuit breaker and Wind Turbine Generator WTG data.
The studies being undertaken include:
- Insulation coordination studies;
- Transient recovery voltage studies;
- Ferroresonance studies;
- Zero-missing phenomena (ZMP) studies;
- Transformer energisation studies;
- Filter capacitor bank energisation studies; and
- 33kV reactor bank energisation and de-energisation studies.
As the manufacturing activities accelerate, WSP continues to be a key partner in this significant project which will deliver a long-term environmental impact and contribute to the UK’s Net Zero target.
