Common use of Phasor Measurement Units Clause in Contracts

Phasor Measurement Units. ‌ A Interconnection Customer shall cause KIAC to install and maintain, at its expense, phasor measurement units (“PMUs”) if it meets the following criteria: (1) completed a Class Year after Class Year 2017; and (2) proposes a new Large Facility that either (a) has a maximum net output equal to or greater than 100 MW or (b) requires, as Attachment Facilities or System Upgrade Facilities, a new substation of 230kV or above. PMUs shall be installed on the Large Facility on the low side of the generator step-up transformer, unless it is a non-synchronous generation facility, in which case the PMUs shall be installed on the Interconnection Customer side of the Point of Interconnection. The PMUs must be capable of performing phasor measurements at a minimum of 60 samples per second which are synchronized via a high-accuracy satellite clock. To the extent Interconnection Customer installs similar quality equipment, such as relays or digital fault recorders, that can collect data at least at the same rate as PMUs and which data is synchronized via a high-accuracy satellite clock, such equipment would satisfy this requirement. Interconnection Customer shall cause KIAC to install and maintain, at its expense, PMU equipment which includes the communication circuit capable of carrying the PMU data to a local data concentrator, and then transporting the information continuously to the Connecting Transmission Owner and the NYISO; as well as store the PMU data locally for thirty days. Interconnection Customer shall cause KIAC to provide to Connecting Transmission Owner and the NYISO all necessary and requested information through the Connecting Transmission Owner’s and the NYISO’s synchrophasor system, including the following: (a) xxxxx XX and MVAR measured at the Interconnection Customer side of the generator step-up transformer (or, for a non-synchronous generation facility, to be measured at the Interconnection Customer side of the Point of Interconnection); (b) generator terminal voltage and current magnitudes and angles; (c) generator terminal frequency and frequency rate of change; and (d) generator field voltage and current, where available; and (e) breaker status, if available. The Connecting Transmission Owner will provide for the ongoing support and maintenance of the network communications linking the data concentrator to the Connecting Transmission Owner and the NYISO, consistent with ISO Procedures detailing the obligations related to SCADA data.
