CAISO Delays Release of Refund Data and MD02 Dispatch Penalties

A need for clarification from the Federal Energy Regulatory Commission has delayed the California Independent System Operator?s submission of refund data to federal regulators, CAISO stated in an April 12 filing to FERC. The grid manager has been processing settlement statement data from 2000-01 ?in various bits and pieces? for months, said Gregg Fishman, CAISO spokesperson. The original plan was to deliver the complete rerun data to FERC by the end of the summer, but November appears to be a more realistic date. ?It is getting more and more complicated all the time,? Fishman said, adding that ?November may be optimistic.? California claims it is owed nearly $9 billion in refunds, and FERC is settling the excess wholesale power claims. CAISO has completed running generators? trades made from October 1, 2000, through January 16, 2001. It states it got hung up on a Department of Water Resources transaction that occurred the following day. Once FERC makes clear how it wants that transaction handled, the production and running of those data will be restarted. The grid operator also announced that the launch of its market redesign dealing with CAISO-dispatched balancing energy in real time and penalties for not complying with dispatch orders will be delayed as well. The MDO2 phase 1B go-live date was moved from May 1 to the fall. While testing the project, grid managers found that parts of the test could not be run simultaneously but had to be performed sequentially. ?[T]he development and testing work is best done sequentially so that the systems are ready for production before you do the final operator training and market simulation,? CAISO stated.
