Communications Innovations –

Enabling Smart Energy

1 © 2012 Electric Power Research Institute, Inc. All rights reserved.

Envision a modernized grid that

leverages today’s digital technology to…

• Increase system reliability and reduce outages

• Provide consumers with tools so they can take control of

their energy usage and save money

• Charge your electric vehicle when rates are cheapest

• Help delay and reduce the

need for new power plants

• Improve the environment

Communications Infrastructure Needs to

be Able to Evolve

• Machine-to-machine connections expected to grow from

100 million in 2010 to 1.5 billion in 2020

• 10% of new vehicles expected to be electric vehicles by

2020

• Distributed and intermittent resources will continue to grow
