IUB Rules Changes to chapter 15 (apply to RECs) New chapter (applies only to IUB rate regulated electric utilities) but… Wind Innovation legislation “Electric utilities shall consider adopting the model interconnection agreement” 2

IUB order adopting new chapter "Those that advocate extending these interconnection standards to all utilities could seek legislation that would end any debate over the extent to the Board's jurisdiction over non-rate regulated utilities. However, if problems develop with respect to interconnections with non-rate regulated utilities, the Board may revisit the jurisdictional issue in a new rule making that would seek to apply the adopted rules to non-rate regulated utilities, even in the absence of new legislation" 3
