National Renewable Energy Laboratory Innovation for Our Energy Future2
Electricity System In the News Today"this is the future of the utility."
“You’re going to have more
devices hooked up to the grid,”
“You have to make sure with these additional connecting points that they’re secure.”
"For the first time in the grid's 100-year history, consumers can understand exactly how much energy they are using and can participate in cost-saving programs,"

Today’s Electricity System
3
• Production follows demand
• Largely electromechanical
• High carbon/low storage
• Blind to distribution/demand
• Very little information and control
• Central planning, design and operation

Our Vision of a 21st Century GridA 21st Century Grid must substantially increase the use of existing production assets
Over 1,000 GW of production assets serve our national power needs, but many of these expensive assets are used only a few times each year. Some are almost never used. We must plan, design, build and operate a system that is much more effective at using these assets.
A 21st Century Grid must readily accommodate new generation, transmission, distribution and consumer technologiesOur ever evolving digital society is already placing unique and difficult demands on our grid. Growing environmental concerns will drive a diversity of cleaner sources of power. These and unanticipated future needs demand that we plan, design, build and operate a “plug and play” grid that maximizes flexibility, extensibility and adaptability.
A 21st Century Grid must actively identify and extract energy efficiency throughout the systemMaximizing energy efficiency from generation to load is critical in meeting our carbon reduction goals. We must plan, design, build and operate a grid that will proactively “mine” carbon throughout, targeting both static and dynamic changes to the system.
A 21st Century Grid must be operated in a highly efficient and highly automated manner.As the grid rapidly increases in complexity, we must plan, design, build and operate a system that is much more automated; sensing changes, responding and adjusting in near real time—eventually becoming an adaptive self-healing system.
A 21st Century Grid must be able to highly differentiate the reliability requirements of consumersOur future, increasingly digital, economy will require higher levels of reliability and power quality. The cost of providing this service will be prohibitive if applied universally. We must plan, design, build and operate a grid that provides for variation in the quality of power while creating a grid that is absolute in providing for critical loads.
