8 of these 41 are not mapped as buildings, so no power figure is estimated for them. 8 are campus boundaries covering 2.64 km² of land. The megawatt figure above divides a national total by building floor area, and the area of a land parcel is not floor area. A site still being built consumed none of the electricity that total measures. Both are counted here and left out of the estimate rather than folded into it, so this region's load is understated by however much those represent.

When these appeared on the map

observed, not surveyed

Data centres recorded in OpenStreetMap at the end of each month. The hatched stretch is before 2017-01, when telecom=data_center was not yet in common use — the near-zero readings there describe the tag, not the country. This is a count of what has been mapped, and OpenStreetMap carries no construction dates.

2 of these 41 facilities do not appear in the curve. The chart counts facilities whose appearance was observed in OpenStreetMap's edit history; one mapped before 2012 has no creation edit to observe. The two numbers answer different questions — how many are on the map now, and how many were watched arriving — and neither is wrong.

What the grid here looks like

reported by OSM contributors

Substations

69 kV and above

Bulk substations

230 kV and above

Highest voltage

500

kV, present in this county

Generating capacity

1,084

MW across 4 plants

A facility drawing hundreds of megawatts connects at bulk transmission voltage, so the second figure matters more than the first: forty 69 kV yards are not a substitute for one 500 kV substation.

Proximity is not connection. Nothing here shows that any facility has contracted power from any of these substations. That gets settled in interconnection filings Helios cannot read, and in several regions those queues now run for years. A county showing no substations may have none mapped rather than none standing.

“First mapped” is when OpenStreetMap recorded the facility, not when it was built — OpenStreetMap carries no construction dates. Mapped area means a building floor plate, campus boundary, or construction polygon according to the “Mapped as” column; those quantities are never added together. The megawatt column appears only for buildings and is their floor-area share of a reported national total, not a measurement.
