Load Research in an AMI World: Why? How? And Results.
November 28, 2017
Our final brown bag seminar of the year is entitled Load Research in an AMI World: Why? How? And Results. With market penetration of a range of new technologies, traditional demand econometric models will no longer be sufficient. End-use and technology hourly load profiles will play a bigger role in accurately capturing the impact of these technologies on system loads and peak demand. AMI systems hold a tremendous wealth of information on customer usage that can be mined for developing these profiles and used in supporting forecasting marketing, and developing energy efficiency programs. This presentation shows how AMI data can be mined without having to add-up millions of data points through load research based on large samples and shows results including developing total house load requirements for solar customers.

Tip: If the failing expression is known to legally refer to something that's sometimes null or missing, either specify a default value like myOptionalVar!myDefault, or use <#if myOptionalVar??>when-present<#else>when-missing</#if>. (These only cover the last step of the expression; to cover the whole expression, use parenthesis: (myOptionalVar.foo)!myDefault, (myOptionalVar.foo)??
