2. Challenges Faced in Sixth Plan
Risk of carbon costs
Increasing requirements for capacity and flexibility resources
New technologies
Energy efficiency
Generation
“Smart Grid” 2

3. Main Points of Sixth Power Plan
Energy efficiency is lowest cost, lowest risk resource
Cost effective conservation expected to cover 85% of 20-year load growth
Increased renewables
Capacity and flexibility resources
Improved operating practices
New resources (e.g. SCCT, DR, storage) 3

4. How Did DR Do? Portfolio model analysis 3000-4000 portfolios analyzed
Uncertainties translated into 750 futures (20 years)
Resources include SCCT, CCCT, conventional and IGCC coal, wind, conservation, DR
=> Expected cost of 750 futures vs expected cost of worst 75 (10%)
Uncertainties include electricity and gas prices, weather, precipitation (important since hydrolectric power system’s output depends on total precipitation). 4

5. Light blue points are “efficient frontier” since they have no other points that are lower in both cost and risk (lower and to left). 5

6. How Close Was DR?
DR option nearest frontier = SH 6

7. Action Plan for DR - 1 Inventory DR programs
Evaluate and demo DR programs
Evaluate DR potential for ancillary services
Monitor new programs
Monitor experience outside the region 7

8. Action Plan for DR - 2
Evaluate Direct Service Industries as source of DR
Complete work of PNDRP
Include appliance response controls in standards
Implement demand response recommendations of NW Energy Efficiency Taskforce
Improve modeling of DR 8
