RE: [emix] Price Curves and delta-T

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.

Subject: [emix] Price Curves and delta-T

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.
