Hello Priya,
Thank you for contacting Microsoft Support. My Name is Rongchun Zhang. I am
the Support Professional who will be working with you on this case.
A new namespace(\\.\root\cimv2\power) has been added to WMI, but it is only
available in Windows Server 2008 R2 and Windows 7. The Win32_PowerPlan
represents power plans on a system. Each power plan is identified through a
unique GUID as well as by a friendly name. Multiple power plans can exist;
however, each computer can have only a single active power plan in effect
at any given time.

Also, based on my researches, the power plans is write into the following
registry key, we also monitor that key to get the notifications.
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Power\User\PowerSchemes
Let me know if this helps, if you have any additional question, feel free
to contact me.
Best regards,
Rongchun Zhang (v-***@online.microsoft.com, remove 'online.')

Note: The MSDN Managed Newsgroup support offering is for non-urgent issues
where an initial response from the community or a Microsoft Support
Engineer within 1 business day is acceptable. Please note that each follow
up response may take approximately 2 business days as the support
professional working with you may need further investigation to reach the
most efficient resolution. The offering is not appropriate for situations
that require urgent, real-time or phone-based interactions or complex
project analysis and dump analysis issues. Issues of this nature are best
handled working with a dedicated Microsoft Support Engineer by contacting
Microsoft Customer Support Services (CSS) at
