This report compiles information about load forecasting practices, focusing on forecast development that relates to electric resource and integrated system planning. A sample of documents focused on integrated resource plans, load forecast methodology, or supporting documents from electric companies and planning agencies was analyzed. Load forecasting methods, processes, data, and assumptions are investigated. The research also conducted a broad, high-level comparison of industry practices with EPRI’s internal long-term load modeling tools. Connections to resource planning needs and directions for future research are identified.
