Summary
This Planning Guide Revision Request (PGRR) aligns the Planning Guide with 1/27/17 ERCOT comments to NPRR562, Subsynchronous Resonance, by accounting for potential Subsynchronous Resonance (SSR) vulnerability in the transmission project planning process, providing references and citations to the appropriate Protocol sections related to SSR, and removing the definition of SSR from the Planning Guides as it is relocated to the Protocols.
