Traditional Generation Options

Base Load Nuclear Coal

Intermediate / Peak Load Natural Gas Combined Cycle Natural Gas / Oil Simple Cycle Natural Gas / Diesel Reciprocating Engines

2012 ADC WINTER FORUM | PAGE 4

Base Load Characteristics

Nuclear 10+ year gestation period High development cost $$$$$ Massive land (1,000+ acres)

Coal 5-10 year gestation period High development cost $$$$ Immense regulatory pressure Significant land (500-1,000 acres)

2012 ADC WINTER FORUM | PAGE 5

Intermediate / Peak Load Characteristics

Combined Cycle 3-4 year gestation period Moderate development cost $$ Moderate land (100 acres)

Simple Cycle / Reciprocating Engines 2-3 year gestation period Low development cost $ Minimal land (50 acres)

Which Option is Best?

Renewable development options are largely dependent upon regional resource availability factors

Traditional generating resources impose fewer restrictions

2012 ADC WINTER FORUM | PAGE 17

Considerations for Realigned Bases Physical space demands Voltage control on distribution system

Potential need for flexible resources Plant operation is foreign to bases Security considerations Potential flight approach path impacts Potential LSE standby energy charges Likely Notice of Availability requirements

Considerations for Closed Bases

Interference with remediation programs Energy development projects have long

gestation periods Public support often less durable “Feed-in tariffs” can prop up public support

Nodal pricing changes as the base becomes a net energy exporter
