Nevermind, I looked at it through a mirror. Its from LAST December, and they used 2636 KWH, an average of 3500 watts continuously over the month. That's around than $0.07 per KWH which is dirt cheap. I pay around $0.13. All the other fees are excessive though.

Yep, 3.5 kwh every single hour over a month is almost a small factory consumption. I guess they are using electric heaters, and have set the thermostats to a high temperature threshold (or a btc mining facility...) They should address that point first.
Anyhow, the subsidy fee is insane.
