  2. Regulation Service – Demand Side Participation • Regulation Service in essentially provided by Generation in ERCOT • Loads have passed the testing and are registered to participate • Market reports indicate the Demand Side resources are not very active in the market

  3. Demand Side Regulation – North American Markets SPP not included as there currently isn’t a market for Regulation

  4. Load Management Universe Market maturity for demand-side assets to participate

  5. New DR products must be bi-directional • Regulation represents required balance in the grid • As likely to require the use of more power as curtailment

  6. Cannot Impact the Customer Requirements are more frequent and have shorter notice Requires intelligent capture of inherent flexibility in processes Requires the ability to define constraints such that operational priorities rank first

  7. Why Limited Load in Regulation Market? • A load does a process or task. Participation in the Electricity Wholesale Market should not impact the process or task • Traditional DR has limited curtailment events and therefore limited impact on the load • Regulation requires the load to respond to 4 second control signals • Regulation as likely to require the load increase consumption as often as curtail consumption • Very few loads have the flexibility to respond in the short timeframe and bi-directionally • Increased communication requirements • Rules limit aggregation to create a network or fleet response

  8. A Network Approach • Generally a single Demand Resource can not respond to the a 4 second signal • A group of Demand Resources acting as an intelligent integrated network can provide robust, reliable and efficient Regulation Service

  9. ENBALA Power Network

  10. What is ENBALA’s Grid Balance Program • It provides moment by moment balance for the grid. • It works within Load defined operational parameters • It is an energy and capacity neutral program • It monetizes the flexibility inherent in Load processes • It requires an intelligently managed network of assets • It is complementary to demand response and other energy management programs • It is NOT demand response • It is NOT an energy curtailment program • It is NOT intrusive to Load operation

  11. Benefits of Demand Side Regulation • Utilizes installed resources • Frees generation to provide other services • Increases the efficiency of the generation portfolio • Reduces cost • Provides an additional revenue stream for the host • Enhances Regulation competition

  12. Market Requirements • Multiple QSE’s • Allowing multiple technology providers to work with a load • Ensure compatibility • Crucial for much wider spread adoption • Sub-metering • To gain access to the specific characteristics of specific loads • Aggregation and Portfolio • Across sub zones • Lower aggregation requirements • Performance measurement at Portfolio not Resource level • Regulation offers without Energy offers ... Not an issue but needs to be considered when developing rules for Demand participation in the Nodal Market

  13. Next Steps • DSWG endorsement to investigate and implement rules that would enable a Network to effectively participate in the ERCOT market

  15. ISO Signal

  16. Resource Response EPN Client Pool beginning to respond to ISO signal.

  17. Resource Response

  18. Resource Response More participants from the Client Pool are responding to requests.

  19. Resource Response The green line is EPNs aggregated response from the Client Pool.

  20. Resource Response 8 binary assets (on/off) responding to the EPN.

  21. Resource Response The 9th participating load is a VFD – providing a continuous response (ranging between 1000 kW – 1750 kW)

  22. Resource Response The aggregate response of each resource in the network is compiled to form a unified regulation response.
