Auto power on computers with GP?

My boss wants to get our environment Energy Star compliant. I know I can configure the power settings to a computer through group policy to send every pc into a hibernate/standby mode. Is there a way for me to have computers power on with something like task scheduler? If so, can I configure scheduler through a GP to all the computers in my domain? I can't do wake on lan due to network restrictions. 


Thank  you for posting this question - I did some more research and may have found a solution that my company can sell EASILY to customers while making pure cash profit from services.

I'm writing the SOW as we speak and working with another engineer to find a testbed client so we could write our own case study.
