The queue, in order

Order calculated by N84
First in queue1,004 MW across the first 5 projects
Order calculated by N84: printed queue position where the register gives one; otherwise entries printed as Gate 2 first, then every other entry by connection date. The register prints no gate for many contracted entries; N84 does not guess their position. Not published by the operator.
