Every capacity figure on this map is an estimate from public sources and research. It can lag, miss a plant, or be wrong. It is not a control-room reading and it is not guaranteed accurate.
Power plants, United States: U.S. Energy Information Administration, Form EIA-860M, September 2026 preliminary monthly inventory. Public domain. Operating, standby, and temporarily out-of-service generators. Retired generators are omitted. EIA says these capacities are preliminary estimates and later months can revise them. When a Markets company is matched, the popup names it. That match is EIA-860 2025 research plus dated deal overrides, and it does not cover Canadian plants. The ownership join was built against an older map layer, so “on the map” can be stale.
Power plants, Canada: NACEI and CanVec (Open Government Licence – Canada, mostly 2016–2017) kept for sites GEM does not cover, including smaller plants. Checked 5 November 2026: no newer national open-government plant list has coordinates and capacity. Statistics Canada is provincial totals, the wind-turbine database is turbines, and CERP is an older clean-energy map. Operating nameplates from the Global Integrated Power Tracker, Global Energy Monitor, September 2026 (CC BY 4.0) update a matched site or add one. Alberta coal is gone; Genesee is 1,857 MW gas. Sundance is mothballed and left out of the total. Pickering units 5–8 are left out of the total: OPG took the last unit offline on 30 September 2026, and IESO showed zero capability on 1 November 2026. An estimate.
Power plants, rest of world: Global Integrated Power Tracker, Global Energy Monitor, September 2026 release. Creative Commons Attribution 4.0. Operating units only, summed to one dot per GEM location. An estimate, not a live fleet. Plants under a few hundred megawatts appear as you zoom in. TransitionZero Solar Asset Mapper rows (CC BY-NC 4.0) are not included. United States, Canada, Mexico, and Puerto Rico are not taken from this file. Click a country to open the same kind of panel a state click opens. Zaporizhzhia is still drawn at its nameplate; the IAEA reports all six reactors in cold shutdown and not generating.
Transmission, rest of world: OpenStreetMap power=line and power=cable ways at ≥220 kV, including HVDC, in public/data/osm/world/. A WORLD region loads its own shards; the North America boot does not. United States, Canada, Mexico, and Puerto Rico are left out so they are not drawn on top of HIFLD or the Canada/Mexico OSM layers. © OpenStreetMap contributors. ODbL 1.0. Extract reported by the OSM server: 10 August 2026. Lines without a voltage tag, and lines under 220 kV, are not in this layer.
Transmission, United States: HIFLD "Electric Power Transmission Lines" (via DOT/BTS NTAD), roughly 69 kV–765 kV. The national view draws ≥220 kV; locking a state loads the full set. Geometry is simplified and paths are approximate.
Transmission, Canada: OpenStreetMap power=line and power=cable ways with a voltage tag, kept at ≥69 kV. The USA + Canada view draws ≥220 kV and HVDC; locking a province loads ≥69 kV. Styled with the same voltage colors as the U.S. lines. This is a separate file (public/data/osm/ca/) so the ODbL share-alike stays on that layer. © OpenStreetMap contributors.
Power plants, Mexico: NACEI Mexico rows (same 2017 federal layers, Open Government Licence – Canada) plus Comisión Nacional de Energía generation permits (datos.gob.mx, CC BY 4.0), historical list updated 2 November 2026. Coordinates are parsed from the permit address when it contains them. Operating, partially operating, and under-construction permits are kept on the map. Permits without coordinates are left off. Megawatts on CNE rows are authorized capacity. Under-construction permits are left out of the capacity total and counted separately in the panel.
Transmission, Mexico: OpenStreetMap voltage-tagged power lines, same colors as the U.S. and Canada layers, in public/data/osm/mx/. © OpenStreetMap contributors. ODbL. The broad view draws ≥220 kV and HVDC; locking a state loads ≥69 kV.
Border interties: NACEI electricity border crossings (August 2017) for Canada–U.S. and for Mexico–U.S. This pack draws 8 Mexico–U.S. points from interties_mx.geojson, plus the Canada–U.S. points. Points, not the line route. Open Government Licence – Canada.
What this is NOT: it does not show the low-voltage distribution network, substation internals, or real-time power flows. The animated "flow" is visual styling only. "TRACE GRID" walks connected transmission segments — a topological sketch, not a dispatch record.
Military installations: public DoD "Military Bases" dataset (FY2024) via USDOT/BTS NTAD. Big loads: a short curated list from public reporting — approximate.
Outlines: U.S. Census TIGERweb states (public domain). Canadian provinces and Mexican states from Natural Earth 1:10m (public domain), simplified. Country click targets are Natural Earth 1:50m admin-0, simplified (public domain). The world view also draws Natural Earth admin-0 at 1:110m, then loads 1:50m pieces for the area in view. Those files stay separate from the OpenStreetMap lines. Basemap: © CARTO, © OpenStreetMap contributors.
The badge on the map is the vintage label: U.S. plants are EIA-860M September 2026 (preliminary). Canadian plants are NACEI/CanVec (still 2016–2017; no newer national open file) with GEM September 2026 operating plants merged on top. Mexican NACEI plants are mostly 2017; CNE permits are the 2 November 2026 list where a coordinate could be read, and under-construction megawatts are left out of totals. Rest-of-world plants are the GEM September 2026 operating set. Clicking a country opens a summary with fuel, plant count, and nameplate. OpenStreetMap lines at ≥220 kV load with the region. TRACE GRID stays on the North America line files. The full write-up is on the About page.
