Strategic Importance

“…it's clear that the power grid needs an overhaul. It needs to be

modernized. As we go into an exciting new period of American

history, we want the most modern electricity grid for our people… we need more investment; we need

research and development…”President BushSeptember 2003

“When the lights go out, modern life as we know it grinds to a sudden halt. 

Transportation is interrupted, communications fail, water systems

shut down, factory work is disrupted, food spoils, businesses lose money, and people are inconvenienced and

even endangered. ”

Secretary AbrahamApril 2004

EIPP Working Group EIPP Working Group Vision – improve power system Vision – improve power system
