LMP Modeling & Calculations Toolbox

LMP Modeling & Calculations Toolbox

September 25-26, 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

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

“Explains a relatively unclear subject.” Economist, Bonneville Power Administration

“Love the suggestions for further reading.” Market Analyst, Southwest Power Pool

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

“Excellent approach: we can read formal textbook LP descriptions ourselves but this added valuable intuition.” Principal Economics & Business Advisor – Transmission Planning, Xcel Energy

“EUCI’s LMP Modeling, Analysis and Forecasting course with Nick Pratley offered a deep dive into the world of LMPs that benefited greatly from Nick’s real world experience & thorough teachings.“ Transmission Planning Engineer, Western Energy Coordinating Council (WECC)

This course examines the value of understanding and forecasting electricity prices in the wholesale markets.  The information will benefit anyone who deals with current and future locational marginal prices (LMPs) in wholesale electric markets by providing a deeper understanding of what drives them:

  1. the complexity of supplying electrical energy around the clock
  2. across an imperfect transmission grid
  3. from a variety of suppliers
  4. without benefit of large-scale storage or rationing

It addresses itself to wholesale power market participants who confront these questions:

  1. How should I price “market risk” in my proposed project?
  2. Why is my existing project suffering and what can I do about it?
  3. What makes a credible LMP forecast?

The content will cover guidance about forecasting prices – with or without sophisticated modeling tools – in the face of new policies, an evolving resource mix and changing market rules. Emphasis will be placed on describing U.S. locational marginal pricing (LMP) style markets.  Going beyond the traditional three-bus LMP example, attendees will learn how the market forms prices in the real world.  Attendees will become familiar with how this knowledge supports decision-making, trading, and negotiation.  Following a review of LMP formation, real-world situations will be dissected using publicly available data.  Finally, some solved “what-if” examples will illustrate the impact on LMPs of emerging bulk power developments using a simplified market model.  For those attendees who want to understand what some people call “magic”, an optional related workshop is dedicated to exposing the mathematics that solve for “what-if” examples.

Learning Outcomes

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

  • Examine the fundamental drivers of electricity prices (supply, demand and transmission network)
  • Review the value and use of price forecasts for multiple market conditions and products
  • Illustrate locational marginal price (LMP) formation with examples
  • Assess the LMP dynamics of unit commitment – how the market chooses which suppliers to buy from
  • Explain the LMP dynamics of economic dispatch – how the market decides how much to buy from each supplier
  • Identify how different resources are offered into the markets
  • Review input data for fundamentals-based forecasting (market mimicking)
  • Explain the LMP distinctions between modeling “day-ahead” (DA) and “real-time” (RT) markets

      Nicholas Pratley has worked in electrical power systems analysis and design for more than three decades.  He began his career as a consulting engineer designing power distribution for heavy industrial projects and moved on to become a subject matter expert in power systems analysis for software vendors and consulting firms.  Mr. Pratley has experience with generation interconnection studies and transmission planning, including more than 15 years in electricity market simulation and price forecasting.  He has received training on Plexos, GE MAPS and PROMOD IV production cost models, and provided training and consulting services using PROMOD for many years.  

      His clients over the years have included transmission owners and developers, municipal utilities deciding whether to join an ISO market or where to construct a new generating plant, competitive generation (IPP) developers forecasting transmission congestion risk for wind/solar/storage project siting and contract negotiation, and pension funds investing in renewable generation projects. His work has influenced decisions to acquire, divest, build or invest in dozens of projects worth multiple billions of dollars.

      In his current professional capacity, Mr. Pratley focuses on the U.S. northeast wholesale electricity markets, federal and state policy, and transmission plans with respect to large-scale renewable energy development.  He also prepares and presents training courses using his expertise in LMP wholesale electricity markets.  He earned B.S. and M.S. degrees in Electrical Engineering at McGill University and the Universite de Montreal polytechnical school.
