Excerpt from Jeff Wettlaufer's blog, and link to register for the beta:
There are a few areas of focus for ConfigMgr R3, with the main engineering effort concentrating on Power Management. Here are the goals for this feature:
Power Management
The goal of this capability is to enable Configuration Manager to further reduce the operational costs of IT by providing basic power management features native to the product. Our approach is based on 3 primary areas:
A. Help the organization plan a power strategy by monitoring current power state and consumption and reporting on machine utilization trends, current power settings and current energy consumption
B. Enable the Administrator to easily create, deploy and enforce specific power settings using the existing ConfigMgr infrastructure
−Ability to set peak and non-peak schedules
−Ability to remediate settings if changed
−Ability to opt out machines from power policy
C. Provide the business meaningful report formats that are relevant to Power Management
