Not yet connected: capacity printed in the latest file of each shown register, leaving out rows printed as built or connected, rows with no MW and rows no longer in the latest file. SSEN rows count the accepted capacity, or the largest MW figure printed where no accepted figure is printed. The NESO Embedded Register is shown on its own because its projects are not linked to the network operator rows and may also appear there. Sum calculated by N84.

Colour steps are quantiles: each step holds about the same number of filled cells (5 steps), so a darker cell is larger than most, not a fixed amount larger.
