Southwest Power Grid Status
Data as of , EIA hourly demand feed.
About the Southwest grid region
The Southwest region covers the desert utilities of Arizona, Nevada and New Mexico, including Arizona Public Service and Salt River Project. Summer cooling load is the story here: demand peaks hard on extreme-heat afternoons, exactly when this map is worth watching.
On the map, this region is part of the Western Interconnection. Its status color comes from the ratio of actual demand to the bias-corrected day-ahead forecast: green means headroom, amber and orange mean it is tightening, and red means demand has met or passed what the operator expected, or a real emergency has been declared.

Grid regions follow balancing authorities, not state lines; split states are listed under the region that serves most of their load.
