SFGATE: "Californians' bills are going up again on Monday, PG&E announces"

https://www.sfgate.com/bayarea/article/pge-bill-increases-2024-18581893.php

Confusing.
First this:
“Starting Monday, most households’ gas and electric bills electric bills will increase about 13%, or $34.50”

But then:
“bills by an average of 3.6% over the next three years,”

3 times 3.6 is not 13 ???
