In 2015 a transitional committee, with representatives from throughout the west, was formed to create a Western Energy Imbalance Market (WEIM) governance structure. Formalized in a charter, the stakeholders designed a governance framework that established the Governing Body, the Body of State Regulators, and the Regional Issues Forum.
