  • 1.  Price Curves and delta-T

    Posted 08-08-2010 16:12 
    Several of the Jira comments for EMIX mention Price Curves, particularly in the ISO markets. I had been led to believe that Price Curves were expressed as a series of time slices, to approximate a curve, and not as literal curves. Now the comments make me think I have misheard….
    If the ISOs use actual curves, can someone point me to them? If instead they are a series of time slices, then the WS-Calendar Partition structure should handle them.

    Tony,
    


    


    The ISO’s use “curves”
that are a series of time slices e.g. 24 one hour slices.  The extra
complexity is that each time slice has a bid/offer curve associated with it
that is a series of MW slices with an associated $/MWH cost.  The IRC
submitted data requirements provide some extra information.  I’ll
see if I can find some plain language explanations from CAISO.
