Prices in the wholesale market are determined using a model called SPD. An SPD case file is a zipped collection of text files containing all of the inputs to and outputs from a single run of the SPD model.
Real-time operation of the system is managed using the real-time dispatch (RTD) instance of SPD. Besides giving rise to the dispatch instructions issued to generators, RTD SPD cases also yield dispatch energy and reserve prices.
RTDP (RTD for pricing) case files may sometimes be published if scarcity pricing is in play. Likewise, PRSS (short price-responsive schedule) case files will be published if RTD cases are unavailable for any reason. When this occurs, dispatch prices for a trading period are derived from the most recent PRSS case pertaining to that period.
