Participants should agree a test plan with the system operator when they intend to conduct any tests on their assets while connected to the system, and when the tests may impact on the System Operator's ability to comply with its Principal Performance Objectives (PPOs).
Examples of the types of tests include distributors conducting drop load tests and generators conducting reactive capability and load rejection tests.
Asset Owners are to use the Test Plan Form to notify the system operator of their intention to conduct system tests. Completed forms are to be submitted at least 14 days in advance for Generator Load or AVR Tests, and 21 days in advance for all other tests. This allows the System Operator and Asset Owners to put in place any necessary operational plans to mitigate the effects of the tests. Where the required advance notice cannot be provided, you will need to contact the Duty Operations Manager.
If you are an Asset Owner and are unsure whether system tests will affect the system operator's ability to comply with the PPOs, please consult the Duty Operations Manager on 07 843 0618.
