GDF Suez NA
This Nodal Protocol Revision Request (NPRR) adds a requirement for the Energy Offer Curve to be offered above a linear curve that starts at $120 and ends at $3,000. If the Ancillary Service Resource Responsibility for Non-Spinning Reserve (Non-Spin) is reassigned to a Generation Resource during the Adjustment Period in accordance with Section 6.4.6, QSE-Requested Decommitment of Resources and Changes to Ancillary Service Resource Responsibility of Resources, the Qualified Scheduling Entity (QSE) shall submit an Energy Offer Curve that meets the requirements of Section 126.96.36.199 for the Generation Resource’s newly assigned Ancillary Service Resource Responsibility for Non-Spin prior to the end of the Adjustment Period.
If the Ancillary Service Resource Responsibility for Non-Spin is reassigned in accordance with Section 6.4.6 from a Generation Resource that experiences a Forced Outage, Derate, or Startup Loading Failure during the Operating Period, the QSE shall submit an Energy Offer Curve that meets the requirements of Section 188.8.131.52 as soon as reasonably practicable after the event.
QSE updates to an Energy Offer Curve entered at the end of the Adjustment Period become effective in ERCOT systems at the next Operating Period. Therefore, if Non-Spin is moved from one Generation Resource to another in the QSE's portfolio during an Operating Hour, any change to the Energy Offer Curve will be effective in the next Operating Period.
There will not be any validation rules to verify the requirements added by this NPRR. The onus is on all QSEs to make the submission/telemetry changes needed to implement these new requirements.
Currently when the Resource stack becomes scarce, energy prices do not steadily increase in relation to increased reliability risk. Rather, they remain relatively low due to competitive forces, right up to the point of market exhaustion, and then rise sharply to the cap. Cushioning the binary nature of the market will facilitate trading in the ERCOT markets, better supports passive Demand response, and can dampen price reversals that can be caused by emergency Load curtailment.
