This course combines real-time presentation, small group breakout sessions, case studies, and Q&A sessions.

Explore the ins and outs of cost-of-service—from key concepts to the nuts and bolts of working through a cost-of-service analysis. Learn how to apply cost-of-service and rate design principles and processes to electric, water, sewer, gas, and other municipal services. Work through the step-by-step process of putting an electric cost-of-service study together and review how to develop a fully functional and unbundled cost-of-service sample model. As you explore the elements of thorough cost analysis, you will gain several lessons learned from real-world examples and group discussions.
