Functional Entities: 4.1.1 Generator Owner 4.1.2 Transmission Planner 4.2. Facilities: For the purpose of the requirements contained herein, Facilities that are directly connected to the Bulk Electric System (BES) will be collectively referred as an “applicable unit” that meet the following: 4.2.1 Generation in the Eastern or Quebec Interconnections with the following characteristics: 4.2.1.1 Individual generating unit greater than 100 MVA (gross nameplate rating). 4.2.1.2 Individual generating plant consisting of multiple generating units that are directly connected at a common BES bus with total generation greater than 100 MVA (gross aggregate nameplate rating). 4.2.2 Generation in the Western Interconnection with the following characteristics:
Compliance Assessment Approach Specific to MOD-026-1, R5 This section to be completed by the Compliance Enforcement Authority Review the response to the Question, if the response was Yes, then: Verify the Entity received a dated technically justified request from the Transmission Planner to perform a model review as specified in R5. Verify the Entity provided the written response to its Transmission Planner containing the following information: Details of plans to verify the model (in accordance with Requirement R2), or Corrected model data including the source of revised model data such as discovery of manufacturer test values to replace generic model data or updating of data parameters based on an on-site review of the equipment. Verify the response was provided within 90 calendar days of receipt of the request. Note to Auditor: Effective date of R5 is 7/1/14. Review footnote 7 regarding how technical justification is achieved. Per FERC Order 796 P16, MOD-026-1 Applicability Section 4.2.4 allows Transmission Planners to request that Generator Owners who otherwise are not covered by the Applicability Section (i.e., whose MVA ratings are lower than the applicability thresholds specified in Section 4 but meet or exceed the Registry Criteria) provide model verifications or correct model data. Auditor Notes: R6 Supporting Evidence and Documentation Each Transmission Planner shall provide a written response to the Generator Owner within 90 calendar days of receiving the verified excitation control system or plant volt/var control function model information in accordance with Requirement R2 that the model is usable (meets the criteria specified in Parts 6.1 through 6.3) or is not usable. The excitation control system or plant volt/var control function model initializes to compute modeling data without error, A no-disturbance simulation results in negligible transients, and For an otherwise stable simulation, a disturbance simulation results in the excitation control and plant volt/var control function model exhibiting positive damping. If the model is not usable, the Transmission Planner shall provide a technical description of why the model is not usable.
