Vulnerable Grid

Smart Grid

Increased communications and control

Increased redundancy

Renewables & Storage

“Defensible” and “democratic”

Easy to expand

Easy to repair, rebuild, fast lead times

Resilient Energy (or other) Systems

Relatively small modules, dispersed, low

cost of failure

Failed components can be detected and

isolated early

Redundant modules can be substituted

Components are diverse

Grid Transformation, a 30 Year Plan

Timeframe Phase Definition Defined by.. (Key Characteristics)

Key Functions / Technologies

RE Penetration

0 - 10 Year Grid

1. Communications & Measurement

Laying the foundation for future technologies through communications. 'Tidying' up our usage.

- Energy efficiency- Demand Response

5% (by capacity)

10 - 20 Year Grid

2. Advanced Components & Dynamic Control

Physical Restructuring of the Grid. Overcoming initial supply & demand variability.

- Network Adaption & Reconfiguration- Islanding
