Traditional grid structure Future grid structure

• Customers receive electricity

• Dedicated networks with limited resources

• Grid as a sole source

• Real-time data/control

• Customers receive/feed electricity

• Networks with shared assets and layered customer resources

• Grid as a sole source, back-up, and two-way flow

• Increased real-time data/control
