NOTICE DATE: December 13, 2016 NOTICE TYPE: W-A121316-01 Operations SHORT DESCRIPTION: Upgrade of Resource Asset Registration Forms and addition of new required data fields INTENDED AUDIENCE: All Resource Entities DAY AFFECTED: February 11-17, 2017 (see below for details) LONG DESCRIPTION: ERCOT is updating the RARF to include the following Resource Registration Glossary Revision Requests (RRGRRs): * RRGRR003 - Modifications to Improve Wind Forecasting * RRGRR006 - Clarification of Descriptions and Alignment with Resource Asset Registration Forms * RRGRR007 - Adding Solar Resource Registration Inputs * RRGRR009 - Adding Voltage Limit Sets, Relay Loadability, MLSE, and GMD Data The full descriptions and supporting documentation for each of these RRGRRs can be found on the ERCOT website. (See the links below under Additional Information.) Structural changes to the RARF include the addition of fields supporting the above RRGRRs. This iteration also changes the Wind form into a Renewable form with support for both Wind and Solar Resources. This change will cause existing Solar Resources to review and add data that was previously on the Gen form or not previously collected for their resource, including detailed collector system and equipment data and models Important to all Resources is the data added in support of RRGRR009 for Geomagnetic Disturbance (GMD) issues. These changes are in support of PGRR046 (Addition of Geomagnetically Induced Current (GIC) Model Building Requirements), and will require Resources to provide some data that is now required and has not previously been collected and may be difficult to provide. Resource Entities are encouraged to plan for the acquisition of this data which will be due by end of March 2017. ACTION REQUIRED: Since much of the new required GIC data will take considerable time to conduct tests and perform calculations, Resource Entities are encouraged to start their review of the new GIC data requirements in RRGRR09 and to begin collecting the data in order to meet the March 31, 2017 due date. All Resource Entities will receive new, pre-populated RARF forms for all of their Resources. The new data fields should be populated and the forms submitted to ERCOT, with appropriate attachments. ERCOT requests that this be completed no later than April 1, 2017. Note that previous RARF versions will not be accepted once the transition has started. Due to the change-over of the RARF database, the last date to submit changes on the old RARF form is February 10, 2017 Submissions on the new RARF from may begin on February 17, 2017.
