CFE Internet

I am currently experiencing the very same thing with my system installed back in February. Installed solar, got the lowest bill ever. Woohoo! Next billing cycle, the highest bill ever.

From March 2022 to November 2022 my CFE bills totalled M$1,632. During that time I was having a carriage house built with all of the use of electricity associated with that and for much of that time the house was occupied.

Then in February 2023 the CFE bill was more than for the entire 10 months in 2022.

In April 2023 the CFE bill was M$6,993!!

Six months into the year, my CFE billing has been M$13,014 on my behalf. That is over three times as much as was paid for the full 12 months in 2022. At this rate, my 2023 CFE cost would be over M$26,000 instead of the M$4,138.24 that I paid in 2022, or 600% more.

And my solar system has produced over 2,200 kWh of energy.

I'm seeing very much the same pattern. My last bill was for M$7300. I've started tracking daily usage and production and entering it into a spreadsheet to calculate what I should be getting billed for. In the year prior to installing the solar, they billed me for an average 1825kwh per billing period. The peak was 2376kwh, which, like you, was during construction.

The building was completed in late January, and the panels came online mid-February; the February/March bill was for 738kwh. Then the April/May bill ballooned to 2786kwh!

Based on a month's worth of daily readings, my usage per billing period should be around 2250kwh--which still seems a little high--but then reduced by the approximately 1900kwh of panel production over the same period. So I should be seeing bills for approximately 350kwh, not almost 3Mwh.

So, have you been able to resolve that with CFE? Did they credit you for the meter error?
