In order for the equipment to be acceptable for interconnection to the utility system without additional protective devices, the interface equipment must be equipped with the minimum protective function requirements listed in the table in Section II.A.5 and be tested by a Nationally Recognized Testing Laboratory (NRTL) recognized by the United States Occupational Safety and Health Administration (OSHA) in compliance with the most current revision of UL 1741, including supplement B (UL 1741 SB) , with settings as specified in the utility’s technical requirements document .
For each interconnection application, documentation including the proposed equipment certification, stating compliance with the most recent version of UL 1741, including UL 1741 SB, with settings as specified in the utility’s technical requirements document , by an NRTL, shall be provided by the applicant to the utility. Supporting information from an NRTL website or UL’s website stating compliance is acceptable for documentation.
If an equipment manufacturer, vendor, or any other party desires, documentation indicating compliance as stated above may be submitted to the Department of Public Service for listing under the certified equipment list on the Department of Public Service website (www.dps.ny.gov) at the Distributed Generation/Interconnections tab.
Certification information for equipment tested and certified to the most current revision of UL 1741, including UL 1741 SB, with settings as specified in the utility’s technical requirements document , by a non-NRTL shall be provided by the manufacturer, or vendor, to the contacts listed on the Department of Public Service website for review before final acceptance and posting under the certified equipment list. Utilities are not responsible for reviewing and approving equipment tested and certified by a non-NRTL.
If a NRTL certifies equipment to the most current version of UL 1741, including UL 1741 SB , with settings as specified in the utility’s technical requirements document , and compliance documentation is submitted to the utility, the utility shall accept such equipment for interconnection in New York State. All equipment certified to the most current revision of UL 1741, including UL 1741 SB , with settings as specified in the utility’s technical requirements document , by an NRTL shall be deemed ‘certified equipment’ even if it does not appear on the Commission’s website under the Certified Equipment list.
Utility grade relays need not be certified per the requirements of this section. For DG systems that are already interconnected with the utility’s electrical system and seek to use the New York State Standardized Interconnection Requirements and Application Process in order to qualify for net metering, no DG system will be required to obtain recertification the latest equipment certification standards, as long as the DG system met the equipment certification requirements by the utility in effect at the time of the DG unit’s interconnection.
