Electric Grid & Wind Infrastructure
Interactive national-scale visualization of 76,051 wind turbines, 94,216 transmission lines, and 79,687 substations. Each turbine shows proximity to the nearest major power line (>=115kV), revealing grid connection patterns. Federal datasets can disappear without warning. By downloading and self-hosting national infrastructure data in PostGIS, we ensure long-term availability for critical analysis.
