2 Presentation Overview Integrated Resource Planning (IRP) summary NV Energy IRP Strategy / Pending Filing Energy Efficiency Demand Side Mgmt. Advanced Service Delivery Supply Plan Renewable Energy Development Transmission Plan On-Line 2

3 NVE IRP Strategy Three Part IRP Strategy 1 Increasing investments in energy efficiency & conservation 2 Expanding renewable energy initiatives & investments 3 Adding transmission and highly efficient dispatchable generating plants 3

4 IRP Strategy Leading to: Energy independence Safe, reliable supplies Predictable prices Smaller carbon footprint lbs CO2/MWh NVE Shrinking Carbon Intensity

5 Integrated Resource Planning (IRP) State law requires electric utilities to file IRP every three years, updates in the form of amendments Analyzes resource options over 20 and 30 years Action Plan identifies steps to be taken over 3 years Approves any generation option including all purchase power agreements over 3 years, all renewable Purchase Power Agreements, any transmission over 200 kv, and company owned generation Key Assumptions with sensitivity analysis Load forecast and market fundamentals 5

6 Integrated Resource Planning (IRP) Continued Evaluate supply options and demand side options (approx. 240 scenarios) Resources selected based upon least cost 20 year economics taking into consideration reliability, environmental impacts, and other factors specified by regulations Financial plan considers ability to finance plan and rate impact to consumers 6

Part 1: Investing in Energy Efficiency and Demand Response 20 Comprehensive Energy Efficiency and Conservation Programs Residential Commercial Demand Response Major

7 Part 1: Investing in Energy Efficiency and Demand Response 20 Comprehensive Energy Efficiency and Conservation Programs Residential Commercial Demand Response Major Accomplishments 10 million CFL s distributed 140 MW of Load Control in ,554,172 MWh avoided in MW of demand reduction 1,049,866 tons of CO2 avoided in

8 Energy Efficiency Continued Plan projected to achieve significant energy and demand savings In aggregate, every $1 of investment expected to yield $2.21 in savings to customers NVE South filed as part of its February 1st filing a three year energy efficiency Action Plan Budget of $174 million 8
