Long-Term Load Forecasting

Long-Term Load Forecasting

July 7-8, 2021 | Online :: Central Time

“I was very pleased with the information conveyed in this course.  The multitude of data that can improve a load forecast and how to implement them was eye-opening.” Sr. Engineer-Delivery System Planning, Alliant Energy

“Great introductory load forecasting course for beginners and planners.”  Senior Power Planner, Modesto Irrigation District

Load forecasting is a fundamental element in utility business operations and planning processes. During the past 120-plus years, load forecasting methodologies have evolved as the industry and related technologies advanced. Consequently, many classical methods are no longer suitable for addressing today’s challenges in the utility industry.

This course offers a comprehensive, updated, in-depth yet practical, scenario-based approach to long-term load forecasting. The content includes:

  • A review of the fundamental concepts and traditional forecasting methodologies
  • A statistical approach that leverages utility knowledge and practical experience
  • Scenario-based forecasting that helps better reflect the uncertainties of the unpredictable future
  • Several advanced and emerging challenges including renewable energy penetration, EV integration and shifting load composition

Learning Outcomes

Attendees will cover content, engage in discussions, and participate in exercises that will allow them to:

  • Review the fundamental concepts of load forecasting
  • Recognize the evolution of classical load forecasting methods 
  • Prepare and build regression models
  • Conduct ex poste forecasting to analyze the source of errors
  • Evaluate long-term, class-specific energy and load forecasts
  • Develop and apply scenario analyses
  • Conduct weather normalization
  • Incorporate real-life utility knowledge and judgment into forecasts
  • Manage how to identify data errors and perform data ‘cleansing’
  • Discuss emerging topics and the applicable problem-solving principles

PV And EV Load Forecasting In MS Excel

Thursday, July 8, 2021 : Central Time


This post-course workshop brings the long-term load forecasting methodologies introduced in the course to the most widely used business forecasting tool: spreadsheets. The workshop starts with an overview of various options available in the market, then zooms into spreadsheet operations.  Attendees will gain hands-on experience, through exercises, building models and generating load forecasts in spreadsheets – with a focus on distributed PV and electric vehicles.  This will be a working session.  Each workshop participant should have available a laptop with MS Excel 2007 (or newer version), including add-ins of Solver and Data Analysis. 

Learning Outcomes

  • Identify various software tools and solutions available in the market
  • Classify the use of different methods to develop forecasts in MS Excel
  • Distinguish the limitation of each method and when to pick which method
  • Examine how to build practical load forecasting models in MS Excel
  • Assess tips and tricks for MS Excel-based load forecasting
