Body of State Regulators (BOSR)

The primary function of the Body of State Regulators is to provide a forum for state regulators to learn about the Western Energy Imbalance Market (EIM), EIM Governing Body and related ISO developments that may be relevant to their jurisdictional responsibilities. The Body may express a common position in the ISO stakeholder process or to the EIM Governing Body on EIM issues; and its members are not restricted from taking any position before FERC or any other forum concerning matters related to the EIM or the ISO. The Body will hold periodic meetings as needed, which can be in-person or by conference call.
