Summary
This Nodal Protocol Revision Request (NPRR) makes two changes to address the energy price suppression and liquidity issues created by ERCOT’s urgent change to procure more Ancillary Service and deploying it early. Specifically, this NPRR extends the treatment of must-take energy from Reliability Unit Commitments (RUCs) in pricing run to Off-Line Non-Spin, when it is manually deployed, by setting the Low Sustained Limit (LSL), Low Ancillary Service Limit (LASL), and Low Dispatch Limit (LDL) of Off-Line Non-Spin Resources to zero in the pricing run; and increases the amount of Responsive Reserve (RRS) and Non-Spin that an Entity can self-arrange above its obligation.
