generation, transmission, ancillary services, efficiency and storage 1 sufficient to offset those presently provided by the lower Snake 2 river dams. The analysis should include a list of requirements for a 3 replacement portfolio that diversifies and improves the resilience 4 and maintains the reliability and adequacy of the electric power 5 system, is consistent with the state's statutory and regulatory 6 requirements for clean electricity generation, and is supplementary 7 to the resources that will be required to replace fossil fuels in the 8 electrical generation, transportation, industry, and buildings 9 sectors. The department and its contractor's assessment will include 10 quantitative analysis based on available data as well as qualitative 11 input gathered from tribal and other governments, the Northwest power 12 and conservation council, relevant utilities, and other key 13 stakeholders. The analysis must include the following: 14 (i) Expected trends for demand, and distinct scenarios that 15 examine potential outcomes for electricity demand, generation, and 16 storage technologies development, land use and land use constraints, 17 and cost through 2050, as well as the most recent analysis of future 18 resource adequacy and reliability; 19 (ii) A resource portfolio approach in which a combination of 20 commercially available generating resources, energy efficiency, 21 conservation, and demand response programs, transmission resources, 22 and other programs and resources that would be necessary 23 prerequisites to replace the power and grid reliability services 24 otherwise provided by the lower Snake river dams and the time frame 25 needed to put those resources into operation; 26 (iii) Identification of generation and transmission siting 27 options consistent with the overall replacement resource portfolio, 28 in coordination with other state processes and requirements 29 supporting the planning of clean energy and transmission siting; 30 (iv) An evaluation of alternatives for the development, ownership 31 and operation of the replacement resource portfolio; 32 (v) Examination of possible impacts and opportunities that might 33 result from the renewal of the Columbia river treaty, revisions of 34 the Bonneville power administration preference contracts, 35 implementation of the western resource adequacy program (WRAP), and 36 other changes in operation and governance of the regional electric 37 power system, consistent with statutory and regulatory requirements 38 of the clean energy transformation act; 39 p. 96 ESSB 5187.SL
