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

NATIONAL RENEWABLE ENERGY LABORATORY
21st Century Electricity System
• Information-rich
• Distributed design and operation
• Clean tech priority
• Ubiquitous storage
• Automated operations
• Highly differentiated energy services
• End-user participation
• Smart homes & buildings
