You need to be more complete in the information provided.
My utility bill doubled last month, and my usage tripled.
Is there some fixed cost, or variation in the cost per KWH based on usage?
What is your usage per month and then calculated from that per day? There seems to be inconsistency in the data you provided.
Once place
typically 30-35 days
high reading 42 days
Another
Did you only consume 264 KWH in 42 days. or 6.3 KWH/day, and even less 95 KWH in maybe 35 days or 2.7 KWH/day. 2.7 KWH/day is a mere 0.123 KW continuous load.
None of this is consistent with current levels of 30 A even for moderately short time periods.
If you were 95 KWH/day then it would be high usage for a residence.
You need to put a recording power monitor on your system. An example is the TED System. About $200 for hardware and software. Plus you need a Windows computer.
You can do it manually, but something is fishy in your data. Is nobody ever home and nothing is on and thus little electricity is used?
More complete facts are needed.
