Before a data centre, a factory or a charging depot can connect, the grid needs room for it. Grid operators publish how much is left at each substation, and who is already queuing for it. Substralis puts those figures on one map, with the source one click away.
824 of 864 Norwegian substations publish how much capacity is available for new demand, through WattApp WattApp capacity mapElbits AS for 42 Norwegian DSOsAvailable capacity at DSO substations, for new demand and for new production, as each DSO publishes it. WattApp stamps every figure with the moment it serves it; it publishes no separate effective date.The DSO's figure does not account for capacity in the overlying grid.

Where nothing is published, the map stays dark: we never fill it in.

Closer in, the grid takes shape.

Its reservoirs, intakes and tunnels are drawn from NVE's hydropower register, and the light moves the way the water does: from intakes up to 830 m above sea level down a 537 m fall to the turbines.
The queue
Then the queue, in place.

Solid columns are reserved; glass columns are still waiting. The largest demand case: Statkraft Energi AS, 900 MW; then Green Mountain AS, 113 MW.

Gaps
Missing stays missing.
North of the Arctic Circle, 93 of 97 substations publish a figure. A figure that isn't published is shown as not published, never as zero or as free. Every number opens its source: who published it, under what licence, and when we last read it.
Read from the people who run the grid.
Grid operators and regulators publish these figures on their own schedules. Substralis reads each source on a timetable, keeps the date on every figure, and flags a source that stops answering.
