One such tool useful in power management is the powercfg tool. Powercfg (or) powercfg.exe can be invoked by typing powercfg at command prompt. Click CTRL+SHIFT+ENTER. This opens the utility to be run as administrator. To get list of power plans issue powercfg -list (or) powercfg -l Choose the guid of the power plan to be renamed.
