I stumbled across a similar problem trying to set the CPU frequency.

If you look at /etc/sysconfig/cpupwer you'll find these variables which 
are pulled in by the systemd service cpupower.service.

# See 'cpupower help' and cpupower(1) for more info
CPUPOWER_START_OPTS="frequency-set -g performance"
CPUPOWER_STOP_OPTS="frequency-set -g ondemand"

 From the service file:

[Unit]
Description=Configure CPU power related settings
After=syslog.target

[Service]
Type=oneshot
RemainAfterExit=yes
EnvironmentFile=/etc/sysconfig/cpupower
ExecStart=/usr/bin/cpupower $CPUPOWER_START_OPTS
ExecStop=/usr/bin/cpupower $CPUPOWER_STOP_OPTS

[Install]
WantedBy=multi-user.target
