Metering and telemetry ensure operational accuracy
Accurate metering of electricity generated or consumed provides key data inputs for accurate settlement calculations. Direct measurement of a generator or load participant through telemetry allows the ISO to manage and monitor power generation in real-time.
Process and requirements
Operating procedures - 5700 metering process
Meter data represents the energy generated or consumed during a settlement interval. The ISO, ISO metered entities, and scheduling coordinator metered entities follow prescribed processes and procedures to ensure the data is settlement quality. These procedures complement, but do not replace, section 10 of the ISO Tariff and Business Practice Manual for Metering.

Additional information, required forms and lists for metered entities
Generating units and load participants must establish and maintain a data processing gateway between plant facilities and the ISO energy management system for the purpose of generation control and monitoring. The ISO requires direct telemetry of participating generators and load by installing a remote intelligent gateway (RIG) for generating units providing regulation energy or a data processing gateway (DPG) or other ISO-approved technology for resources providing non-regulation ancillary services or supplemental energy.
Application access
The ISO and its market participants must adhere to rigorous requirements to help ensure the integrity and confidentiality of commercially sensitive or proprietary information and data, as well as to protect the ISO grid and its assets.
