PRR 548

Settlement for Mismatched Inter-QSE Energy Schedules

slide2

From PRR 548, section 4.7.2 (2),

(a) If ERCOT detects a mismatch in the scheduled quantities or Congestion Zone designation for an Inter-QSE Trade for energy, ERCOT shall promptly notify both the receiving QSE and sending QSE that a mismatch exists and shall allow them fifteen (15) minutes to resolve the mismatch and submit modified schedules.

Operationally, nothing changes. Parties with mismatched schedules still receive mismatch notifications

slide3

From PRR 548, section 4.7.2 (2),

(b) If mismatched Inter-QSE Trades are not resolved in the allotted time, then ERCOT shall consider any amount of a mismatched Inter-QSE energy schedule submitted by a QSE as a Resource which exceeds the corresponding Inter-QSE energy schedule submitted by a QSE as a Load as a “mismatched amount delivered to ERCOT.” ERCOT shall also consider any amount of a mismatched inter-QSE energy schedule submitted by a QSE as a Load which exceeds the corresponding Inter-QSE energy schedule submitted by a QSE as a Resource as a “mismatched amount received from ERCOT.” ERCOT will use these amounts to settle with each offending QSE as specified in Section 6.9.8, Settlement for Mismatched Inter-QSE Energy Schedules. Additionally, ERCOT will charge a mismatched schedule-processing fee for providing this service.

slide4

From PRR 548, section 6.9.8

The mismatch amount delivered to ERCOT for each QSE for each zone shall be any amount in the mismatched inter-QSE energy schedules submitted by the QSE as a Resource which exceeds the corresponding Inter-QSE energy schedule submitted by a QSE as a Load. The mismatch amount received from ERCOT for each QSE for each zone shall be any amount in the mismatched inter-QSE energy schedules submitted by the QSE as a Load which exceeds the corresponding Inter-QSE energy schedule submitted by a QSE as a Resource.

operations
Mismatch notification sent to parties with mismatched schedule starting at 11:00 and continuing until:

Mismatch is cleared

End of the adjustment period

Both parties receive a mismatch notification

No change due to PRR 548

Settlement

  • Currently three scenarios:
  • Mismatch due to no counter-party
  • Mismatch due to different zones submitted by QSEs
  • Mismatch due to scheduling different amounts between counter-parties
  • PRR 548 only addresses Scenario 3.
  • Scenarios 1 and 2 will continue to be resolved in settlements as they are today.

Current Mismatch Settlement

To clear the mismatch, ERCOT replace the counterparty with a schedule to or from ERCOT. Each party then pays, or is paid by the market for the power.

MCPE = $20

QSE A

MISD = -1 * MISAMTD * MCPE

MISD = -1 * 250MWh * 20

MISD = -$5,000

QSE A is paid $5,000

QSE B

MISR = MISAMTR * MCPE

MISR = 300MWh * 20

MISR = $6,000

QSE B pays $6,000

The extra $1,000 goes to purchase 50MWh of balancing necessary
