This project intends to modify the System Operating Limit (SOL) Methodology to accomplish the following objectives:
To better align the SOL Methodology with the new NERC TOP and IRO Reliability Standards that have an effective date of April 1, 2017.
To better align the SOL Methodology with the NERC SOL White Paper, which served as a conceptual basis for the development of the new NERC TOP and IRO Reliability Standards.
To effectively implement the WECC OC-approved Path Operator Task Force (POTF) Recommendation issued on September 5, 2014.
NERC mandatory Reliability Standards FAC-011-3 and FAC-014-2 require Reliability Coordinators (RC) to have a documented methodology for developing SOLs, including Interconnection Reliability Operating Limits (IROLs), which are used in the operations horizon in the RC Area. The Standards also require Transmission Operators (TOP) to establish SOLs consistent with the RC’s SOL Methodology.
The last major revision to the SOL Methodology occurred on August 30, 2013 as part of the SOL Methodology Phase II Task Force initiative. The 2016 SOL Methodology Revision Project represents the next major revision to the System Operating Limit (SOL) Methodology.
To complete this project, Peak has employed a strategy similar to that of the IRO-017-1 Outage Coordination Project:
Peak has established a list of stakeholders comprised of two individuals representing each NERC-registered TOP in the RC Area.
Peak has created a small team of fifteen individuals from those stakeholders to work with Peak on more granular level to revise the SOL Methodology.
