ResourceParameters

The following parameters are supported in SPP. These are all part of the ‘Energy Operating Limits’ template.

Notes:

  • Parameters must be submitted for a specific market stage—DAM or RTBM. As such, each parameter has a “-DA” or “-RT’ suffix to indicate the market.
  • Only submit the parameters that you wish to change. The APX MarketSuite® will take existing value for non-submitted parameters and use those for the submission to SPP. The APX MarketSuite® regularly pulls down data from the SPP portal, so should have the latest info.
