  • Data release and accessibility phase 2 - convergence bidding information release
    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
      The release of a daily market summary report and the hourly net cleared virtual quantities by node at the close of the real-time market will promote market efficiency in the ISO energy markets once convergence bidding is implemented in February 2011. Because the nodal information will be sufficiently aggregated, publishing the net cleared quantities by node is permissible under Section 20.2 of the ISO tariff. Accordingly, implementation of this data release approach will not require a subsequent FERC filing.—Briefing to Board of Governors: Feb. 11, 2010
