What information should be represented by the Private Use Network (PUN) in the Current Operating Plan (COP) for the “Go-Live” approach?
For the “Go-Live” approach, only generation unit capacities that are available to ERCOT markets, i.e. the surplus that is available after covering the PUN loads should be represented in the COP. PUN Generation Resources that serve PUN loads are shown in the COP as On-line and available with Low Sustained Limit (LSL) equal to zero and High Sustained Limit (HSL) representing excess capacity after serving PUN load. This is net capacity of PUN generating unit that is available and could be offered into ERCOT energy and Ancillary Service (AS) markets. PUN generating units that are fully used for serving PUN load will have LSL = HSL = 0 MW. For PUN Generation Resources whose entire capacity is available to ERCOT markets, this capacity should be reported in the COP with appropriate status and with physical LSL and HSL, i.e. no netting of PUN load.
