SCHEDULE 3 - DISTRIBUTED ENERGY RESOURCES INTERCONNECTION PROCESS <br />(1) Any time the interface hardware or software, including protective relaying and generation control <br />systems are replaced and/or modified, the Area EPS operator shall be notified. This notification <br />shall, if possible, be with sufficient warning so that the Area EPS personnel can be involved in the <br />planning for the modification and/or witness the verification testing. Verification testing shall be <br />completed on the replaced and/or modified equipment and systems. The involvement of the Area <br />EPS personnel will depend upon the complexity of the Generation System and the component <br />being replaced and/or modified. Since the Interconnection Customer and the Area EPS operator <br />are now operating an interconnected system. It is important for each to communicate changes in <br />operation, procedures and/or equipment to ensure the safety and reliability of the Local and Area <br />EPSs. <br />(2) All interconnection-related protection systems shall be periodically tested and maintained, by the <br />Interconnection Customer, at intervals specified by the manufacture or system integrator. These <br />intervals shall not exceed 5 years. Periodic test reports and a log of inspections shall be <br />maintained, by the Interconnection Customer and made available to the Area EPS operator upon <br />request. The Area EPS operator shall be notified prior to the period testing of the protective <br />systems, so that Area EPS personnel may witness the testing if so desired. <br />(a) Verification of inverter connected system rated 15kVA and below may be completed as <br />follows; The Interconnection Customer shall operate the load break disconnect switch and <br />verify the Generator automatically shuts down and does not restart for at least 5 minutes <br />after the switch is close <br />(b) Any system that depends upon a battery for trip/protection power shall be checked and <br />logged once per month for proper voltage. Once every four years the battery(s) must be <br />either replaced or a discharge test performed. Longer intervals are possible through the use <br /> approval. <br />352 <br />
