  4. Stuff to think about • PCRR nominations • 24-hr period runs from June 2008 - May 2010 • PCRR nominations are still submitted per month • For non-baseload PCRRs: either capacity OR refund type, per year • If capacity type: limited to 40% of eligible MWs, per year • Note: this is the last nomination submission for EDS – R7.5 is a true-up allocation • CRR auction bids • CRR bids are submitted per year, per TOU (?) • Only Peak-Weekday, Peak-Weekend or Off-Peak bids (NO 24-hr bid) • Anything else?

  5. Caveats • Still need to restrict each CRR AH to 650 bids • Defects from R7.3 still exist • E.g. not able to post a OPT buy bilateral trade posting • Source/sink mapping file that can be downloaded from application is inaccurate. We will be posting an accurate source/sink file on Monday, April 7th.
