This report discusses the findings from OG&E's Smart Grid program, focusing on the impact of enabling technologies and dynamic pricing rates on demand response. It includes detailed analyses of programs designed to reduce load during peak periods and the effectiveness of various pricing plans. The report examines participation rates, load savings achieved, and lessons learned from both the 2010 and 2011 demand response studies. Insights into customer behavior and load reduction potential are presented, offering a roadmap for future energy management strategies.

  1. OG&E’s Smart Study TOGETHER: Impact Assessment of Enabling Technologies and Dynamic Pricing Rates Katie Chiccarelli, Craig Williamson January 24, 2012

  2. Agenda • Program Background • Program Design (Rate/Technology) • 2010 DR Study • Hypothesis, results • 2011 DR Study • Results • Phase I vs. Phase II participants • What do there results mean? • What rate/technology = load savings • Can we defer generation?

  3. OG&E • 9 power plants: 6.8 GW • 778 MW - wind • 765k customers in OK & AK • 30k square mile service area • 23k miles of overhead distribution lines • 500 substations • 1100 distribution circuits

  6. Study Design—Price Plans VPP TOU Off-Peak/Low 4.5¢/kWh 4.2¢/kWh Standard 23¢/kWh 11.3¢/kWh High 23¢/kWh Critical 46¢/kWh Critical Price Event 46¢/kWh 46¢/kWh

  7. Study Design—Price Plans VPP TOU Off-Peak/Low 4.5¢/kWh 4.2¢/kWh Standard 23¢/kWh 11.3¢/kWh High 23¢/kWh Critical 46¢/kWh Critical Price Event 46¢/kWh 46¢/kWh

  8. Study Design—Price Plans VPP TOU Off-Peak/Low 4.5¢/kWh 4.2¢/kWh Standard 23¢/kWh 11.3¢/kWh High 23¢/kWh Critical 46¢/kWh Critical Price Event 46¢/kWh 46¢/kWh

  9. Study Design-Technology Energate Pioneer Silver Spring Networks

  10. DR Study Hypothesis • 20% Participation by December 2014 • 150K customers (50k per year) • 1.33 kW per customer (~70 mW per year)

  11. 2010 Study Results

  12. 2010 Study Results Validate Hypothesis VPP rate combined with PCT enabling technology maximizes load reduction

  13. 2010 Results – VPP Critical Price Weekday

  14. 2010 Results System Peak Max Reduction

  15. Desired Results

  16. Shifting and Conservation

  17. VPP Demonstrates Price Elasticity

  18. 2011 Study Results

  19. 2011 study results • Results from 2011 confirm 2010 • Load shapes changed, Demand Reduction approx. the same (2010 v. 2011) • Strategically called events can • Stretch out savings • Add secondary bump to savings closer to the system peak • 2011 Summer was HOT!

  20. 2010 versus 2011 Impacts-TOU-CP

  21. 2010 versus 2011 Impacts-TOU-CP

  22. 2010 versus 2011 Impacts-VPP-CP

  23. 2010 versus 2011 Impacts-VPP-CP

  24. 2010 versus 2011 Impacts-VPP-CP

  25. Event Day Savings–Short Event

  26. Event Day Savings–Longer Event

  27. Conclusion • Potentially Avoid Future Generation • Study results show a 1.3 kW reduction per customer is possible. Participation targets will achieve goal • Event calling enables reduction at time of peak • Plans for 2012 • ~40k customers enrolled in SmartHours • 72 mW reduction • Discontinue roll out of IHD
