Today’s LiveWire Spotlight looks at a report recently issued by the ERO Enterprise offering direction to Transmission Owners and Generator Owners responsible for calculating and maintaining accurate Facility Ratings used in the reliable planning and operation of the BES.  The document identifies four common themes that impact the ability of Facility owners to derive and sustain accurate Facility Ratings — lack of awareness, inadequate asset and data management, inadequate change management, and the inconsistent development and application of Facility Ratings methodologies.  

It is hard to overstate the attention that the ERO Enterprise gives to the accuracy of Facility Ratings.  A review of the 16 guides, webinars, workshops, Lessons Learned, and compliance expectation papers cited in Appendix A of this report provides a hint of their concern.
