Topic: The IE’s conclusion that Xcel’s use of “Flicker Charts” or the “Flicker curve approach” from IEEE 141-1993 (R1999) as standards for voltage fluctuation has been superseded by IEEE P1453
Topic: The IE’s conclusion the Xcel is in violation of Tariff Section 10, F, Original Sheet 139 for not complying with the latest revisions of the ANSI/IEE standards.
Topic: The IE’s determination that it is reasonable that Xcel use a value of 2.0 % for Flicker in both its “aggregate” and “individual” PV systems for the computer models used in the Tariff Section 10, step 3 and 4 feasibility study computer models for the SunShare-Becker Interconnection.
Topic: Whether the IE’s determination that Xcel perform cost estimates to a +/- 20% certainty level departs from the Xcel’s tariff process and/or requires a change to the tariff.
Topic: Whether the IE’s determination that Xcel perform cost estimates to a +/- 20% certainty level was necessary to resolve the dispute concerning the SunShare-Becker interconnection.
Topic: Whether the IE’s determination that Xcel may not charge SunShare for costs that are above the +20% cost estimate departs from Xcel’s tariff.
Topic: The IE’s determination that SunShare may not use the Advanced Functionality Inverters to perform Flicker Mitigation without Xcel’s explicit permission, until such time as the inverter functions have been tested and certified by UL/IEEE standards.
Topic: The IE’s determination that it is “reasonable for SunShare to pay for a radio or wireless based path between the SunShare Bartlett Interconnection and Xcel SCADA system for the purposes of meeting NERC compliant data transmission requirements, rather than a dedicated telephone line, provided that it can clearly demonstrate that such a data path can meet the provisions of the latest edition of NERC CIP-005-5 Standard and related Standards.”
Topic: At what point in the interconnection study process must the applicant demonstrate compliance with applicable telemetry-related NERC standards, if these standards are provided?
