I'm currently using this:

cpupower frequency-set --governor powersave

but it resets after each reboot.

You can use tuned. Read the documentation → Power Management Guide - Tuned. Although with tuned you can set a lot more valuable attributes than CPU governor only, you can create a custom profile (if you want) only for the CPU governor.

A custom profile for the CPU governor only, could have been:

sudo mkdir /etc/tuned/myprofile/
echo -e '[cpu]\ngovernor=powersave' | sudo tee /etc/tuned/myprofile/tuned.conf

Start the service and select the profile.

sudo systemctl start tuned.service 
sudo tuned-adm profile myprofile

This will be permanent after you load the profile "myprofile" via the tuned-adm tools. Don't forget to enable the service in systemd in order to load at every system boot.

sudo systemctl enable tuned.service
