Reactive Power Projections

The project aims to develop a robust methodology for projecting reactive power demand, investigate the reasons behind variations in reactive power on the transmission network, and create a projection tool to predict reactive power demand for up to 15 years at GSP (Grid Supply Point) level.  
The aim of the project is that the primary outcome should be a robust methodology and a tool for predicting reactive power demand at Grid Supply Points (GSPs) within the GB network. This could enable NESO to better control voltages on the transmission network, reducing operational complexity and costs.  
By understanding the reasons behind the variation in reactive power demand and projecting future trends, NESO aims to make informed operational and investment decisions, ensuring the resilience and efficiency of the network as it evolves to accommodate increasing renewable generation and changing demand patterns.
