Marginal Cost of Electricity Services

Marginal Cost of Electricity Services

February 15-16, 2023 | Online :: Central Time

“This course was relevant and thought provoking. Time very well spent!” – Manager, Rates and Finance, BC Hydro

“Great speakers, thorough coverage of topics, knowledgeable presenters.” – Staff Rate Analyst, PSE&G

The increase of low-cost renewables has increased uncertainty for utilities when calculating avoided or marginal costs.  Avoided cost analysis must now capture future states in ways that cannot be accommodated with traditional approaches. A proper marginal cost study provides pertinent information on a utility’s avoided cost of energy and capacity due to reduced demand in different time periods and locations. Marginal cost estimates can be used to evaluate and design energy efficiency and demand response programs, as well as renewable resources. Marginal generation capacity costs have been set according to the least-cost means by which capacity can be provided. An avoided-cost analysis provides the utility manager with a broader spectrum of possibilities as avoided costs can be used to compare demand options to demand options, supply options to supply options, and demand options to supply options.

Register now to explore the changing landscape for determining marginal/avoided costs, get conceptual and institutional background information, review technical underpinnings and receive recommendations that your company can contemplate.

Learning Outcomes

  • Discuss the concepts and definitions of marginal cost
  • Review the various electricity services including generation, transmission, distribution, and customer as well as output metrics
  • Explore the estimation methods including contemporary estimation issues
  • Review the elements of generation services including short and long run marginal costs
  • Review the elements of transmission services including locational marginal pricing
  • Review the elements of distribution services including load- and customer-related incremental costs
  • Discuss the elements customer service as they pertain to the incremental costs of providing services, by service type
  • Examine examples of marginal costs in support of electric vehicle tariffs, avoided costs of conservation and DSM programs, and incremental value of power supply contracts with solar facilities
