Ticker symbol “NVE”
2 NV Energy
Consolidated as single brand Serves 2.4 million Nevadans A Vision for Our Energy Future
3 Three Part Energy Strategy
Increasing investments in energy efficiency & conservation Expanding renewable energy initiatives & investments Adding highly efficient dispatchable generating plants
4 Strategy Leading to:
Energy independence Safe, reliable supplies Predictable prices Smaller carbon footprint

5 Guiding Vision
To be the premier provider of energy for Nevada
6 Investing in Energy Efficiency
435 million kWh saved Enough for 34,000 homes Carbon cut by 278,000 tons
7 Energy Efficiency Programs
$55 million invested 7 million CFLs since 2003
8 Renewable Energy Commitment
Committed to large & small projects Contracts for over 500 MW Direct investments
9 Nevada Leads the Way
Legislation in 1997 Early commitment to renewables Costly to build but no fuel needed
10 Portfolio Standard
20% of kWh sales by 2015; 25% by 2025 1/4 from energy efficiency & conservation 3/4 from solar, geothermal, wind & other
11 NVE Renewables Portfolio
35 projects totaling 750 MW; 300 MW in-service; 125 MW under construction 2 of the U.S.’s largest operating solar plants Nevada leading the way in solar & geothermal Also adding 200 to 400 MW of wind Adding 2 PV projects larger than Nellis

24 Geothermal Energy
Nevada ranks 2nd in resources behind CA Nevada’s ultimate potential thought to be over 2,000 MW
High Moderate
Source: NREL 25 Geothermal Development
200 MW, 16 plants in-service 3 plants under construction add 120 MW Over 100 MW more under development
26 One Nevada Transmission Line – ON Line
235-mile high-voltage line Connects all of Nevada Facilitates renewable energy
27 Part 3 of Strategy: Dispatchable Clean Generation to Assure Reliable 24x7 Power
• Dispatchable peaking capacity • Units capable of following intermittent solar & wind • 24x7 efficient base-load generation
28 New State-of-the-Art Plants
Doubled owned capacity since 2006 Highly efficient gas-fired plants Dispatchable to balance load and intermittent renewable resources
