Standard Attachments
Attachment A
Attachment A is illustrative only; it is not a requirement. Requirement R1 calls for an amount of Contingency Reserve to be maintained, predicated on an amount of generation and load required in Requirement R1, Part 1.1., specifically:
“1.1 The greater of either:
-
- The amount of Contingency Reserve equal to the loss of the most severe single contingency;
- The amount of Contingency Reserve equal to the sum of three percent of hourly integrated Load plus three percent of hourly integrated generation.”
Attachment A illustrates one possible way to account for and calculate the amount of generation upon which the Contingency Reserve amount is predicated.
Below is a practical illustration showing how the generation amount may be calculated under Requirement R1 for Balancing Authorities (BA) and Reserve Sharing Groups (RSG).
| BA1 / RSG 1 | Generation | Part of Generator |
| Generator 1 | 300 MWs online | Yes |
| Generator 2 | 200 MWs online | Yes |
| Generator 3 (Pseudo-Tied out to BA2) | 100 MWs online | No |
| Generator 4 QF (has backup contract) | 10 MWs online | No |
| Generator 5 QF in EMS | 10 MWs online | Yes |
| Generator 6 | 0 MWs online | Yes |
| Dynamic Schedule to BA2 from BA11 | (50 MWs) | |
| Generation | 620 MWs | (The sum of gen 1–6) |
| BA generation (EMS) | 510 MWs | (The sum of gen 1, 2, and 5) |
| Generation to use Under BAL-002-WECC-1 | 460 MWs** | (The sum of gen 1, 2, and 5 minus Dynamic Schedule) |
** Assumes BA1 and BA2 agree on Dynamic Schedule treatment. If no agreement, BA1 would maintain reserves based on 510 MWs Generation.
| BA2 / RSG2 | Generation | Part of Generator |
| Generator 11 | 100 MWs | Yes |
| Generator 12 | 100 MWs | Yes |
| Generator 3 (Pseudo-Tied in from BA1 | 100 MWs | Yes |
| Dynamic Schedule from BA1 to BA2 | 50 MWs | Yes |
| Generation | 300 MWs | (The sum of gen 11, 12 and 3.) |
| BA generation (EMS) | 300 MWs | (The sum of gen 11, 12 and 3.) |
| Generation to use Under BAL-002-WECC-1 | 350 MWs** | The sum of gen 11, 12 and 3 plus Dynamic Schedule) |
** Assumes BA1 and BA2 agree on Dynamic Schedule treatment. If no agreement, BA1 would have to maintain reserves based on 510MWs Generation and BA2 would determine its generation to be 300 MWs.
1Note: This Dynamic Schedule is not the same as the Generator 3 Pseudo-Tie.
