U.S. Power Grid Faces Challenges
The power grid in the U.S. is actually three large interconnected systems that move electricity around the country. Standards have been developed to ensure coordination for the linked operations, but challenges exist, including the cost and feasibility of building new transmission lines, integrating multiple fuel sources, and ensuring the grid’s overall security and reliability.

Importance of Securing Energy
Regardless of how they are powered, the world’s electrical grids are at risk.
“The nation's critical infrastructure, such as the electricity grid and financial sector, is vital to supporting the basics of life in America. Market forces are pushing infrastructure operators to put their infrastructure online, which enables them to remotely manage the infrastructure and increases their efficiency. However, when our infrastructure is online, it is also vulnerable to malicious cyber activities that could cripple essential services.“

How CMU is Addressing the Challenge
Innovative solutions that help energy suppliers deliver energy more reliably, detect and fix problems faster, and cost less are essential.
Researchers at Carnegie Mellon are developing solutions to enable variable power from wind and solar sources and automatically control load levels in order to help consumers decide when it is best to charge heavy equipment such as plug-in hybrid vehicles.
