Download PDFPrint Event Details


The emergence of renewable and variable energy resources has drawn attention to the supplemental services — beyond the basics of energy, generating capacity, and power delivery — that bulk-power systems and balancing areas require to ensure grid stability.  Some of these ancillary services (such as regulation and reactive power) are required during normal operations to maintain the necessary balance between generation and load in real-time and maintain voltages within the required ranges.  Other ancillary services (such as contingency reserves) provide insurance to prevent minor problems from becoming full-scale catastrophes or to restore the bulk-power system to normal operations after a major outage occurs.

This course will explain the functions performed by each ancillary service with a focus on the real-power services.  It will also provide an in-depth treatment of several features of ancillary services, regulation and reserve market design: 

  1. Co-optimization in the scheduling and dispatch of energy and ancillary services
  2. The theory and practice of reserve and regulation shortage pricing
  3. The pricing and scheduling of demand side ancillary services
  4. Market design approaches to scheduling, pricing and bidding these services
  5. Comparison of ancillary services, regulation and reserve products across the various North American independent system operators (ISOs)
  6. Value and cost components that inform market participant ancillary services, regulation and reserve products bidding opportunities

Learning Outcomes

  • Identify what ancillary services are and why the power system needs them
  • Discuss what is required to provide ancillary services, regulation and reserve products
  • Examine what the cost drivers are for ancillary services, regulation and reserve products
  • Assess the reasons that co-optimization of energy and ancillary services is becoming a standard feature of wholesale power markets and how they function
  • Examine the relationship between ramp constraints, regulation shortage prices, price variability, and the returns to being on dispatch
  • Identify the options of faster ramp and more accurate provision of regulation
  • Identify how the increasing penetration of renewable energy, storage and distributed energy resources influence the need and provision of ancillary services, regulation and reserve products
  • Interpret FERC Orders and other actions that affect ancillary services, regulation and reserve markets
  • Address participation challenges in the ancillary services, regulation markets and reserve markets
  • Evaluate ancillary services, regulation and reserve products’ cost, value and bidding approaches
  • Examine the need for inertia, virtual trading and other new ancillary services, regulation and reserve products, services and pricing models
  • Analyze and understand how the development of demand ancillary services regulation and reserve products is related to the level of price caps and the introduction of meaningful shortage pricing
