There is a somewhat hidden WMI namespace that holds WMI classes you can use to manage power plans.
The code below lists all power plans on your local machine, and using -ComputerName, you can easily retrieve this information remotely as well:
PS> Get-CimInstance -Name root\cimv2\power -Class Win32_PowerPlan PS> Get-WmiObject -Name root\cimv2\power -Class Win32_PowerPlan
This produces a nice table view:
PS> Get-WmiObject -Name root\cimv2\power -Class Win32_PowerPlan | Select-Object -Property ElementName, Description ElementName Description ----------- ----------- Balanced Automatically balances performance with energy consumption on capable... High performance Favors performance, but may use more energy. Power saver Saves energy by reducing your computer’s performance where possible.
