LMP Forecasting – Methods and Applications

LMP Forecasting - Methods and Applications

December 14-15, 2023 | Online :: Central Time

“This course is exactly what I was looking for to better understand price formation and dispatch in the electricity market.  The speaker is the only industry expert who addresses this topic in such complete detail.”  Associate, EDF Renewables

“Great way to learn how LMPs are calculated.” Rates and Policy Director, Northwest Requirements Utilities

“Presentation highly organized.  Speaker extremely knowledgeable and very clear in his explanations.  Very extensive research conducted in preparation for presentation.”  Senior System Metering Engineer, TriState G&T

“This course provided the insights into price formations that has taken my understanding to the next level.”  Market Operations Engineer, ERCOT

This course examines several approaches to predicting electricity prices for multiple purposes over different time horizons.  It begins with an overview of the characteristics of electricity prices and later provides the physical and mathematical background to explain the reasons for those characteristics.   Both fundamentals-based and time series-based approaches will be described in practical terms.  Forecasting approaches will be recommended based on the end use, time horizon and which data are (un)available, but all approaches offer the potential to forecast prices at multiple locations of interest at the same time.  Distinctions will be made between when high accuracy (for both timing and magnitude) forecasts are required by some use cases and when they are not required.  Specific real-world uses cases will be explored, using real-world data.

The content will also provide many insights into the quantities to be forecast and, from there, cover guidance about forecasting prices – with or without sophisticated modeling tools.  Emphasis will be placed on forecasting prices in U.S. locational marginal pricing (LMP) style markets.   A survey of forecasting approaches will be presented, examining their applicability to specific forecasting time horizons.  And, for those who are not professional forecasters, a discussion of “Do It Yourself” forecasting will round out the course.

Learning Outcomes

Using real-world situations and illustrative examples, this instructional course will:

  • Review the characteristics of Locational Marginal Prices
  • Discuss the value of forecast accuracy in multiple use cases
  • Explain the underlying structure that determines electricity prices
  • Illustrate locational marginal price (LMP) formation
  • Address real-world applications, questions and solutions
  • Review four time horizons and the appropriate price forecasting approaches for each
  • Demonstrate what can be done with and without sophisticated modeling tools
