1. (1) The assessment shall identify estimates for the electrical supply and demand balance, for the forward 5- and 10-year periods, under high-, medium-, and low-risk scenarios. The assessment shall identify loads and resources online and loads and resources expected by reliability year ending September 30.
2. (2) The assessment shall focus on the Independent System Operator system, with an emphasis on the electrical demand, load, supply, or resource for load-serving entities subject to the Public Utilities Commission’s jurisdiction. The assessment shall break down loads and resources by type of load-serving entity by year by transmission access charge area.
