Need for Data Acquisition Provisions. In recognition that the coordination of the system operations by the Parties may be facilitated by the sharing of power flow and other real-time information from meters and other equipment at the Interconnection Points, the Parties may agree to cooperate on the installation and operation of data acquisition system (“DAS”) equipment including, but not limited to, remote terminal units (“RTU”), meters, MW/MVAR and Volt transducers, telecommunication devices, lease lines, and any related equipment at points which shall from time to time be mutually agreed upon. Therefore, the Parties establish this Appendix III to govern the general principles of such DAS arrangements. Each of these general principles may be modified within and by a specific agreement for a specific DAS arrangement. Pursuant to a separately negotiated and executed agreement, a Party’s RTU, or equivalent devices, may be shared by the other Party. Therefore, pursuant to such agreement, the RTU shall support multiple dedicated communication ports with mutually agreed upon communication protocols. If a backup telemetry system or data is required by one Party for their own use, the requesting Party shall be responsible for installing and/or maintaining the field devices and associated telecommunication system at their cost. Where there are protocol restrictions because of existing legacy systems, industry standard protocols such as DNP 3.0 shall be offered. If a proprietary communication protocol is to be used solely for one Party, the requesting Party shall be responsible for the cost of adding the customized communication protocol to the RTU. The following real-time data shall be provided to all parties as minimum requirements: three phase bi-directional energy flows (e.g., MWh, MVARh), three phase instantaneous power flows (e.g. MW, MVAR), per phase RMS voltages, per phase RMS currents, and frequency measurement with at least two decimal points resolution shall be provided. In addition to the real-time data, the status of all switching devices associated with the interconnection circuit(s) shall be provided. For the energy flow data, either or both accumulated data or hourly interval data shall be provided based on mutually agreed formats. If accumulated data is used, the owner of the RTU will freeze the accumulated data buffers at the beginning of each clock hour and the other Party shall read the frozen data. This shall be accomplished in a manner that provides both Parties with the same accu...
