Yes, that price is insane!

I don't have A/C, do have net metering and do have solar panels, so I intentionally picked the plan with the highest costs during the day in the summers and I pay 24c/kWh only in peak hours during the summer.

Author may be a high energy user and on a tiered monthly-usage plan rather than a TOU plan; if that is the case than the solar panels may be saving energy billed at the highest marginal rate which might be 25c/kWh. My previous house had in-ceiling electrical resistive heating only and I accidentally got a 4-figure electric bill the first January I lived there because one thermostat was broken. IIRC everything after the first NkWh (where N was a crazy high number) was billed at around 25c.

That's wild. I live in an extremely hot and humid part of the country, in the Gulf Coast; probably the area with the highest AC demand in the summer. I routinely exceed $300 a month in the hotter months.

Do you have a particularly small or recently-built, well-insulated house?
