UL 1741 Listed. The Underwriters’ Laboratories (UL) 1741 standard (Inverters, Converters, Controllers and Interconnection System Equipment for Use With Distributed Energy Resources) addresses the electrical interconnection design of various forms of generating equipment. Many manufacturers submit their equipment to a nationally recognized testing laboratory that verifies compliance with UL 1741. This "listing" is then marked on the equipment and supporting documentation.

3.1 Applicability The Fast Track Process is available to an Interconnection Customer proposing to interconnect its Generating Facility with the Cooperative's System if the Generating Facility’s capacity does not exceed the size limits identified in the table below. Generating Facilities below these limits are eligible for Fast Track review. However, Fast Track eligibility is distinct from the Fast Track Process itself, and eligibility does not imply or indicate that a Generating Facility will pass the Fast Track screens in Section 3 .2 below or the Supplemental Review screens in Section 3.4 below. Fast Track eligibility is determined based upon the generator type, the size of the generator, voltage of the line and the location of and the type of line at the Point of Interconnection. All Generating Facilities connecting to lines greater or equal to 35 kilovolt (kV) are ineligible for the Fast Track Process regardless of size. For inverter-based systems, only certified inverter-based systems are eligible for the Fast Track Process and the size limit varies according to the voltage of the line at the proposed Point of Interconnection. Certified inverter-based Generating Facilities located within 2.5 electrical circuit miles of a substation and on a mainline (as defined in the table below) are eligible for the Fast Track Process under the higher thresholds set forth in the table below. In addition to the size threshold, the Interconnection Customer's proposed Generating Facility must meets the codes, standards, and certification requirements of Attachments 4 and 5 of these procedures, or the Cooperative has to have reviewed the design or tested the proposed Generating Facility and be satisfied that it is safe to operate. < 5 kV ≤ 20 kW ≤ 50 kW ≥ 5 kV and < 35 kV ≤ 50 kW ≤ 100 kW 1 Must be an UL certified inverter.
