Mapped Arizona data center sites, with their power, water and risk
One app for every Arizona county: data center sites, power, grid and FEMA risk, with hearing alerts and an API. 64 data center buildings are mapped in 3 of its 15 counties, and businesses pay 12.45¢ per kWh for power, 7% below the US average.
What stays open? The map, the county pages and every data center page stay open to everyone.

Buildings and sites that OpenStreetMap volunteers have tagged as data centers. It counts mapped objects, not an official register, so some data centers are not on it yet.
Drought, the water view
FEMA's drought rating is our water view for each county: how much drought is expected to cost a year, against the rest of the US.
Expected annual loss (FEMA rating)
FEMA's National Risk Index estimates what each hazard costs a year, on average, in damage to buildings, crops and people. It then rates each county or state against the rest of the US, from Very low to Very high. "Rate high" here means Relatively high or Very high.
AI campuses
A large data center campus built for AI computing, on Epoch AI's list of AI data centers. "Being built" means Epoch lists no computers running there yet.
Cents per kWh
The average price businesses paid for one kilowatt-hour of electricity in 2025: their total bills divided by the power they bought. Arizona ranks 22nd most expensive of 51 (the 50 states and DC).
ISO/RTO
An ISO or RTO runs the high-voltage grid and the wholesale power market for a region. Most of Arizona has none: each utility balances its own area.
Commercial sales
Electricity sold to businesses: offices, shops and most data centers. EIA does not count data centers on their own; most sit in this group. Arizona sold 29.4 TWh in 2019 and 37.6 TWh in 2025.
Latest 12 months (2025-09 to 2026-08): 41.2 TWh, +11.6% on the 12 months before.
TWh (terawatt-hours)
A terawatt-hour is a billion kilowatt-hours: a measure of how much electricity is made or used over time.
Proposed capacity
New generators that plant owners have reported to EIA for 2026–2030. They are plans, not commitments: some are delayed or dropped.
Other (EIA's catch-all)
EIA's own "Other" group, for sources outside its main fuel types. EIA does not split it further in this table, so neither do we.
Balancing authority
The organisation that keeps supply and demand matched, minute by minute, in its area. Each utility reports its sales under one.
Water taken in and used up
Taken in (withdrawn): water a power plant pulls from a river, lake or well to cool. Used up (consumed): the part that evaporates and does not go back. These are power plant figures, the grid's water, not data center water.
