Western Energy Imbalance Market (WEIM) Governance Development

The implementation of WEIM necessitates that all entities, whether inside or outside California, are given a voice in the decision-making process going forward. The WEIM Transitional Committee is a stakeholder body tasked with developing a long-term governance structure and advising the Board on WEIM. Through this initiative the WEIM Transitional Committee will first evaluate the general relationship between the ISO and WEIM Governing Body, and criteria for evaluating governance proposals. Then the committee will vet its proposal for long-term WEIM governance with stakeholders.


As part of its proposal to provide Western Energy Imbalance Market (WEIM) services to other balancing authorities in the west, the ISO worked with stakeholders to establish a governance structure that gives western entities a decision-making voice. In 2013, a two-step process to form a long term WEIM governance structure was initiated. The first step established a temporary advisory committee - the Transitional Committee - which developed an independent WEIM governance structure. In 2015, the advisory committee’s long-term governance proposal for the western energy imbalance market was implemented. Visit the Governing Body page.
