See East Asian and U.S. infrastructure on one evidence map.
GridOS connects public records for power plants, grids, substations, pipelines, data centers, and network hubs so operators, owners, relationships, and regional demand and supply can be examined together.

Regional demand and supply
The latest metric available under each country's public reporting system is shown. Ratios and ranks are comparable only within the same country and method.
| Country · region | DemandⓘA public metric used to represent electricity use (demand) for each region. It may not equal total consumption, and methods differ by country. | SupplyⓘA public metric for electricity supply (often renewable generation), based on what each country discloses. | Supply ÷ demandⓘCalculated as supply ÷ demand. Use it as a rough indicator and compare only within the same country. | PeriodⓘThe reporting period for the metric (year/month, etc.). Periods can differ across countries. |

Demand covers large energy users, not all regional load. Supply is renewable generation.
Time scales and populations differ across the five countries. Values must not be ranked directly across countries.

Publication, security, and inference policy
Public value comes from explicit evidence and disclosure boundaries, not from maximizing coordinate detail.
- 01
OSM source and derived data remain in a separate schema with ODbL attribution.
- 02
We do not reconstruct unpublished transmission, pipeline, or substation locations through spatial inference.
- 03
Physical connections and proximity inferences are recorded separately, with verification methods visible.
- 04
IXP and operator relationships use primary public materials, and every record links to a dated source version.
