The power plants, transmission circuitry and substations, which deliver electricity to American consumers across more than 220,000 miles of high voltage transmission lines are known collectively as "the Grid."
Today's century-old Grid still mirrors the maze of streets, roads and byways that it did at its inception. Yet electricity is increasingly vital as a part of our overall energy picture.
The Grid is now expected to:
1. Move ever more electricity flexibly, efficiently & affordably.
2. Eliminate "bottlenecks" which cause power outages.
3. Integrate new, intermittant power sources like wind and solar effectively.
4. Carry the growing torrents of informational data.
Improvement is essential, so a grid-wide transformation akin to building a 21st century Interstate Highway System for energy is proposed. It envisions a master plan serving the whole country with "entrance & exit ramps" as needed for states & locales. It would build additional infrastructure, while conserving and upgrading what we already have.
This advanced product, known as the SMART GRID, would:
1. Add more long distance extra-high voltage transmission lines to connect remote renewable-energy sources (i.e., wind and solar "farms") with population centers.
2. Replace existing overhead conductors with advanced systems to increase capacity.
3. Use new techniques to install and maintain underground cables making them less costly.
4. Use advanced digital technology to distribute electricity and detailed information about its usage all along the grid. That will enhance reliability and allow utilities and consumers to gauge real-time costs so they can adjust their usages accordingly.
5. Enable new technologies such as plug-in hybrid electric vehicles, smart appliances, and home automation software and hardware.
