Lisa White Ph.D. Candidate School of Environment and Sustainability University of Saskatchewan May 30th, 2012 Research objectives Determine how sustainability principles & criteria can be integrated into the development of energy futures using an SEA methodology Through applying SEA & sustainability to an electricity sector case study SEA Case Study of Electricity Futures in SK Apply a structured SEA framework using an expert-based assessment of alternative future scenarios for electricity development in SK Generalized SEA framework: Reference framework VECs (assessment criteria) Alternatives Impact assessment Preferred alternative 3 overall goals, to: Determine a preferred path for Saskatchewan Demonstrate an SEA process that operationalizes sustainability criteria Examine the methodological implications Reference framework 3,840 MW capacity in 2009 Additional 4,100 MW capacity required by 2030 Requires a long-term strategic plan No formal SEA requirement in SK Natural Gas 29% Wind 5% Hydro 22% Coal 44% Development of Sustainability Criteria Preliminary criteria based on case studies and academic literature Final list refined with 7 electricity experts 8 criteria developed, including: C1: Adaptive capacity C2: Emissions Management C3: Employment & Income Sufficiency C4: Ecological Integrity C5: Security of Supply C6: Energy Production & Transmission Efficiency C7: Aboriginal Rights C8: Public Health & Safety 5 Alternatives for next 30 yrs. 0% 10% 20% 30% 40% 50% 60% 70% 80% 90% 100% 110% 2009 Mix A1 A2 A3 A4 A5 Conv. Coal CCS Coal Hydro Small Scale Wind Biomass Nuclear Natural Gas Alternative assessment 44 member expert panel participated 17 from government, 15 from private sector, 13 from NGOs and ENGOs Panel assessed the alternatives based on Saaty’s Analytical Hierarchy Process (AHP) Quantification of subjective judgements Online Expert Choice Comparion Suite software utilized for the assessment Criteria importance weighted using a paired comparison approach (9 point scale) Alternative preference ranked pairwise based on each criterion Weighting the criteria Evaluating the alternatives Data analysis Individual assessment values were compiled into matrices (in Expert Choice) MCA used to calculate the eigenvectors of the matrices (in Expert Choice) Individual criterion weight scores & alternative preference scores Results aggregated & analyzed using exploratory data & non-parametric statistical analysis (using SPSS software) Data analysis cont. Robustness Based on a concordance analysis Used to look for rank reversal issues Sensitivity analysis Changing criterion weights based on ‘what if’ conditions & removing inconsistent responses Used to determine if alternative ranking would change Based on the interval ranking of alternatives (Euclidean distance from 0 to 1) The results Criteria weights: Health & Safety > Security of Supply > Ecological Integrity > Production & Transmission Efficiency > Employment & Income Sufficiency > Aboriginal Rights Alternative rankings: A3 > A5 I A2 I A4 > A1 Sensitivity tests: Removal of inconsistent responses has no effect on alternative rankings C7, Aboriginal rights shifts most preferable alternative to A5, natural gas and least A2, nuclear Implications For electricity planning in SK ○ Implementation issues ○ Infrastructure, cost, environment For SEA methodology ○ Structure & flexibility ○ Quantitative impact assessment methodologies ○ Sustainability Questions?
