Yeah, that’s pretty high. Hawaii average in 2023 was around $0.42 per kWh, so the OP might live in a rural area of Hawaii. Do realize when comparing to Florida, the average monthly consumption was roughly 2.2 times that of Hawaii. So, the average monthly electricity bill in Hawaii (the usage charges) is not a great deal higher than in Florida.
$0.534/per kWh is the regular Winter rate for PG&E in my “area”. CA has “area rates”...rates based on Zip Codes (hotter interior valley areas pay less than the coastal areas for electric in Summer, etc.).
A quick calculation of my last bill when subject to the new rules shows that my bill will remain about the same...the B.S. aspect is “income based” base rates vs. the same base rate for everyone. (PG&E had NO “base rates” before this...just a “minimum connection charge” of $10. even if you used NO power) “Infrastructure” costs were/are plowed into the “per kWh” rate currently...they will be in the “base charge” starting late next year...see:
