[CentOS] CentOS 7 turn off power saving by command line

In CentOS 6 gconftool-2 (command line) is used to enable/disable items.

In CentOS 7 I found "settings->power-> blank screen" as something I
wish to configure by the command line?

How is that accomplished?

I brought up gconf-editor and searched for power and blank and found
nothing.

How can I control this setting from the command line?

Thanks
