  1. Demand Response in Integration of Renewable Generation:Pacific Northwest Experience Ken Corum NASUCA Mid-year Meeting June 10, 2013, Seattle WA

  2. What Kind of DR? • DR 1.0 • Vast majority of DR experience • Peak load reductions • Limit of ~ 100 hours/year • DR 2.0 • Reductions and increases in load • Throughout day and year – perhaps 8760 hours/year

  3. Illustration of DR 2.0 Electric Water Heaters

  4. Illustration of DR 2.0 Electric Water Heaters

  5. More Examples of DR 2.0 • Refrigerated warehouses • Pulp and paper plants • Municipal water pumping and treatment • Data centers • Electrochemical processes (e.g. aluminum) • Electric vehicles (cars, forklifts, etc.) • More….. “the more we look, the more we find”

  6. Features of DR 2.0 Loads? • Storage • Heat • “Coolth” • Elevated water, compressed air • Intermediate product (e.g. wood pulp) • Flexible delivery of service • Timing of oxygenation of treated water • Timing or location of data center service

  7. Time Scale of DR 2.0 • Hours – load shifting • Minutes – “load following”, 5-minute energy market(?) • Seconds – regulation

  8. Cost Effectiveness? • Early days – many potential alternatives • Hardware, market structure, forecasting • Mass market options (e.g. WH) need “market transformation” strategies to reduce cost and simplify participation • C&I options need detailed understanding of processes (joint benefit with energy efficiency) • Portfolio management

  9. Caveats • Not all loads can do DR 2.0 • Like batteries, resource available now depends on recent deployments • Will require innovative commercial relationships
