NGED's Network

The code in this git repository is the research component of NGED Flexpectation, an NIA-funded innovation project with National Grid Electricity Distribution (NGED), a distribution network operator (DNO) in Great Britain. The project is run by Open Climate Fix.

NGED's network (as of May 2026) consists of:

  • 1,161 primary substations (33/11 kV and 66/11 kV)
  • 271 bulk supply points / BSPs (132/33 kV and 132/66 kV)
  • 52 grid supply points / GSPs (400/132 kV and 275/132 kV)
  • ~1,500 industrial customer generators (not domestic); roughly 558 at 33 kV or 132 kV connected to GSP/BSP busbars, and ~1,000 on the 11 kV network downstream of primaries
