Background
| Status: | Approved |
|---|---|
| Date Posted: | Nov 20, 2012 |
| Sponsor: | Planning Working Group (PLWG) |
| Urgent: | No |
| Sections: | 3.10.2, 3.11.4.1 |
| Description: | This Nodal Protocol Revision Request (NPRR) adds a sixth year (Year 6) to the Steady State Working Group (SSWG) Data Set B base cases. Revisions to the Transmission Project and Information Tracking (TPIT) and Annual Load Data Request (ALDR) procedures will be required as result of this NPRR. The Planning Working Group (PLWG) has submitted Planning Guide Revision Request (PGRR) 026, Addition of Year 6 to the SSWG Base Cases, to revise related sections of the Planning Guide. |
| Reason: | The present bases cases (Data Set B) cover a planning period of five years. This timeframe is not sufficient to address large regional projects with scopes requiring long-lead time consideration (i.e., 345-kV and certification). In many cases, the entire project spectrum including initial assessments, identification of alternatives, project selection, certification, and implementation takes longer than five years. Additionally, near-term economic projects potentially having reliability drivers beyond the five-year planning horizon can be supported with this additional base case. Similarly, this additional Year 6 base case can help provide direction to the selection of a longer term solution potentially resulting in a more cost-effective near-term plan development. Lastly, proposed North American Electric Reliability Corporation (NERC) Reliability Standard TPL-001-2, Transmission System Planning Performance Requirements, requires assessment for one of the years in the "Long-Term Transmission Planning Horizon (years 6-10)." |
