4 Integrated Resource Planning theast Alaska Sout Plan that economically schedules what, when, and where to build, based on available energy supplies Long term time horizon Competes generation, transmission, fuel supply and DSM/energy efficiency options Includes renewable energy projects (including Hydro) Arrives at a plan to build future infrastructure for minimum long run cost to ratepayers Considers risks Consideration of financing options 4

5 Integrated Resource Planning Objective Function: 2012 Cumulative Present Value Costs Sout theast Alaska With consideration of: Regional issues and differences Energy security Risks 5

13 Project Objectives and Scope Sout theast Alaska Current Situation Limited it interconnections and redundancy Limited economies of scale Dependence on fossil fuels Rapid electric heating conversions Aging infrastructure Difficult financing SE Study Plan that economically schedules what, when, and where to build, based on available energy supplies 50-year time horizon Competes generation, transmission, fuel supply ppy and DSM/energy efficiency options Includes future CO 2 costs Includes renewable energy projects (including Hydro) Arrives at a plan to build future infrastructure for minimum long-run cost to ratepayers Proposed AK-BC transmission line will be considered Considers risks Consideration of financing options Potential SE Results Increased DSM/energy efficiency Increased renewables (including hydro) Increased transmission AK-BC transmission line Potential Future Situation More robust transmission Diversified supplies Spread risks State financial assistance Regional planning Wise resource use Respond to electric heating conversions New technologies Prioritized List of Capital Projects Energy challenges are significant; SE will provide information required to make regional decisions. 13

14 Project Objectives and Scope theast Alaska Sout 50 year horizon Assessment of regional loads Projections of fuel and electricity generation costs Analysis of potential generation resources Diversify energy supplies Comprehensive list of current and future generation, transmission and electric power infrastructure projects Long term plan for capital project additions with emphasis on first three years 14
