It’s 240V/400A split-phase service, PNW, around $0.11/kWh. Air conditioning is a big part of it when the temperatures are high. Also charging multiple bEV, a lot of 24x7 loads: half-dozen fridges, a couple large freezers, wine cellar, about 1kW of IT+AV equipment, etc.

Not the person you were replying to, but my June statement lists 1,800 kWh. I'm in a two-bedroom apartment in Texas. The primary consumer of power by far is AC, which is kept at 68 degrees in the summer (partly for temperature, partly for humidity). My effective rate after all the fees was $0.11/kWh.
