Future Power System Architecture (FPSA) systems engineering methodology


The Future Power System Architecture project has been tasked to set out, and provide evidence for, the functions that will need to be performed in the future power system as a result of its ongoing transformative change.

The primary focus is therefore on the functions that will be needed to manage the technical challenges facing the system in 2030 assuming that it achieves the outcome defined by the National Grid’s Gone Green energy scenario.

The system engineering process applied to the project places functions at the heart of the analysis and considers them in the context of the four dominant time horizons:

  • Investment planning
  • Operational planning
  • Real time operation
  • Markets and settlement

By identifying the functions already in place and comparing the need for extended or new functions, the analysis provides the gap analysis that helps understand the scale of the transformation required.
