It can be very helpful to distribute a power plan in Group Policy, especially if there are laptops needing wifi SQL connections which must not ever cut off. The best way I have found, is to use this location in GP:
User Configuration / Control Panel Settings / Power Options
and create a new one there, with a new name, set as default. It may be helpful to do the same under Computer Configuration just in case there are hidden overrides out there.
There is another set of settings using the power plan GUID, but I have not found any way to automatically distribute power plans via group policy and keep the GUID consistent in all machines, even import/export does not do this.
