  • Data release and accessibility phase 1 - transmission constraints
    With the April 1, 2009 implementation of the California ISO new market system based on Locational Marginal Pricing, stakeholders expressed a desire for the release of additional information enabling them to better understand market results and more effectively participate in the ISO markets. In response, the ISO is conducting a stakeholder process to explore the issue of data release and accessibility in ISO markets and to implement appropriate enhancements to its current data provision practices.
    • Outcome
      Reports and data on transmission constraints are released to market participants through California ISO systems. — Implemented: July 13, 2010; FERC Order: July 12, 2010 (ER10-1229); Board of Governors approval: Feb. 11, 2010
