If you wish to reduce a nomination in either the Intraday 1, Intraday 2, or Intraday 3 nomination cycles, the Elapsed Pro Rata Scheduled Quantity (EPSQ) is the floor below which you cannot reduce your nom. Essentially, this calculation determines what portion of your nomination is considered to have already flowed at the time you wish to reduce it.

With the changes to nomination deadlines and the additional nomination cycle (ID3) which will go into effect on April 1, 2016, the calculation of EPSQ will also have to change. For detailed information and examples of the new calculations, please see California Gas Transmission’s updated FAQ related to EPSQ.
