EGGonomics · UC Davis College of Engineering · USAEE 2026 case competition. Every map is a static snapshot of public-source data; hover any feature for its values. The affordability maps are the filed report's evidence; layers marked beyond the filed paper are exploratory GIS, not affordability claims.
Virginia nexus — every layer on one map (mixed vintages; read the note)
The affordability gap explorer — toggle gap $ vs burden rate, search any locality
Household energy burden by hex, 0–30% AMI cohort — affordability, defined
Service territories — the report classes burden by EIA-861 territory
Burden clustering — an exploratory robustness check; counts are stochastic
Data-centre air permits — demand-side context
The generation fleet (Virginia envelope)
Transmission by voltage — 65% of paths inferred, not surveyed
Virginia's 345 kV+ lines
State-line transmission crossings — not a measured flow
≥345 kV crossings — a capability count, not flow
Grid single points of failure (envelope)
Grid connectivity fragility (Getis-Ord) — not an affordability metric
Virginia and neighbouring states — geographic context
