Welcome to the EPRI Load Shape Library 5.0 developed under Project Set P170A Analytical Frameworks for Year 2016. The Preceding version Load Shape Library (v.4.0) was developed in the Year 2016.
The objective of the Load Shape Library is to facilitate the collection, use and functionality of a library of representative electric load shapes by climate zone, geography or by utility. Representative load shapes are a challenge to acquire due to the cost to collect end use level load data. While EPRI and the utility membership work towards acquiring national and regional statistically representative load data, EPRI Program 170 A (End-Use Energy Efficiency and Demand Response Analytics) has developed an analytical framework with a web accessible database of best-available U.S. load data. The database includes end-use data aggregated over NERC regions, whole premise data aggregated over major cities and residential efficient technology measures aggregated by city, utility region and climate zone. Each of these have been acquired either through EPRI’s field pilots, regional utility studies (e.g., BPA’s Pacific Northwest RBSA) or through historical collaborative activities such as the EPRI CEED (Center for End-Use Energy Data) PowerShape™ data of 2000-01. Until statistically-valid, representative load data by climate zone, class and building type are acquired, EPRI continues to revise the framework annually and populate the library with newer load data as available.
