Stalls, NACS, prices, outages and removals, as they're published.Stalls added, CCS to NACS conversions, price moves, outages, and sites leaving public listings, across every network we track, as they're published.
Hardware changes come from the DOE's Alternative Fuels Data Center (AFDC) listings. The date is when the listing changed, which can trail the work on site by weeks; Tesla's listings refresh in batches, so its changes arrive together. Stalls are charging ports; connector counts are cables, so a site can add CCS cables without adding stalls.
Tesla also reports its own stall counts and max power, months ahead of the DOE. A rise in either shows here marked “per Tesla”, dated when we detect it; “Faster charging” means max power rose 10% or more. When the DOE listing later catches up, it isn't shown twice.
Prices are the peak per-kWh rate each network publishes, on the rate shown for the site (for Tesla, the public rate, or the Tesla-vehicle rate at Tesla-only sites). Moves within two days are netted, so a change that reverses itself doesn't show; a site that cycles between rates every few days shows once, as “Price varies by day”.
Offline 24h+ means the network (Tesla, Electrify America, Blink and others) or the DOE reported the site unavailable for at least a day. Shorter blips are left out.
Removed from listing means the site has been missing from the DOE feed for 48 hours or more, which is when it leaves our lists too. That is not a confirmed closure: most come back, half within a week, and the row disappears when one does.
Highlights keeps every hardware change (faster charging included), sites missing for 30+ days (about 1 in 4 of those return), price moves of 10% or more plus network-wide price waves, and outages of 3+ days at sites with 4+ stalls. The other views show every change of their kind.
