Initiatives

Stakeholder input is essential to ISO planning processes and for the success of new initiatives from policy development to implementation. We are committed to providing ample opportunity for stakeholder input into ongoing policy initiatives to develop enhancements to the Western Energy Imbalance Market (WEIM). As entities join, we anticipate new proposals, and have processes in place to gather stakeholder feedback to ensure we evolve to meet participants’ needs.
