Translating Portfolio Analysis to a Cost Effectiveness Frontier

Effeciently compare costs and benefits of Demand Response (DR) programs with avoided costs in power systems over time, incorporating uncertainties. Explore a diverse set of resources and test portfolios against future scenarios to enhance decision-making. Ongoing work focuses on diversifying DR programs and maximizing ancillary service benefits.

  1. Translating Portfolio Analysis to a Cost Effectiveness Frontier Ken Corum, NW Power and Conservation Council

  2. Cost Effectiveness of DR • “Compare cost of DR to cost avoided by DR” • Comprehensive evaluation of avoided cost • entire power system • over time • uncertainty • For practical guidance, a simple rule approximating comprehensive method 2

  3. Council’s Portfolio Model • Uncertainties translated into 750 futures (20 years) • Resources include: • natural gas • conventional & advanced coal • wind • conservation • demand response • 1000-4000 portfolios tested against futures 3

  4. Council’s Portfolio Model • Each portfolio => 750 NPVs of costs • distribution w/ average cost, risk 4
