PMUs The PMU shall be installed on the Large Facility on the low high side of the generator step-up transformer, unless it is a non-synchronous generation facility, in which case transformer for the PMUs shall be installed on the Developer side of the Point of InterconnectionLarge Facility. The PMUs PMU 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 Developer or Connecting Transmission Owner 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. Developer or Connecting Transmission Owner shall be required to install and maintaininstall, at its Developer’s expense, PMU equipment 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’s data concentrator. Connecting Transmission Owner and the NYISO; as well as will store the PMU data locally for thirty days. Developer The Developer’s and Connecting Transmission Owner’s responsibilities concerning the PMU and PMU equipment shall provide be set forth in Appendix A to this Agreement. Connecting Transmission Owner and shall provide the NYISO all necessary and requested information through the Connecting Transmission Owner’s its and the NYISO’s synchrophasor system, including the following: (a) xxxxx XX and MVAR measured at the Developer high side of the generator step-up transformer (or, for a non-synchronous generation facility, to be measured at the Developer side of the Point of Interconnection)Large Facility; (b) generator terminal voltage and current magnitudes and angles; (c) generator terminal frequency and frequency rate of change; andand (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 its data concentrator to the NYISO, consistent with ISO Procedures detailing the obligations related to SCADA data.
