| Description: | This Nodal Protocol Revision Request (NPRR) adjusts the language introduced by NPRR827, Disallow PTP Obligation Bid Award where Clearing Price exceeds Bid Price by $0.25/MW per hour, to account for the steady state that will result when ERCOT implements the long-term, automated change affecting Point-to-Point (PTP) Obligation bid clearing. With NPRR827, ERCOT introduced a manual workaround to remove certain awards that were considered in the optimization, which negatively impacts counterflow in DAM Settlement. With this NPRR, ERCOT will update the Day-Ahead Market (DAM) optimization engine to address the situation where a contingency disconnects a Resource Node. Instead of ignoring the PTP MWs in contingency analysis if that PTP sources or sinks at the disconnected point, the engine will “pick up” those MWs and distribute them to other nodes. The Settlement Point Price will include that “pick up” Shift Factor in the price calculation. In this implementation, the optimization price and the Settlement price will be equal (within one cent for rounding). |
