Introduction to Utility Depreciation, February 27-28, 2019 in Chicago, IL

This course guides utilities and energy personnel through the strategies necessary to achieve accurate and meaningful data to provide to consultants doing depreciation studies. The material that will be covered in the course will include, but will not be limited to, a discussion of company historical source data used for depreciation study purposes; development of a depreciation study database; how and why historical information is analyzed; other factors considered in life and salvage analysis; a discussion of depreciation methods, procedures, and techniques for depreciation rate development; and what is included in a depreciation study report. The course is not simply a lecture, but is intended to be interactive with the goal of addressing to the greatest extent possible, questions from the attendees, to maximize the participants’ understanding of the depreciation study process, results, and the application in revenue requirements.
