Scheduling Coordinator Metered Entity

CAISO requires that resource owners select a Meter Data Management Agency (MDMA) to submit Settlement Quality Meter Data (SQMD) on behalf of the Scheduling Coordinator (SC). This is in lieu of the former requirement to provide a certified and inspected revenue meter from which CAISO would process settlement quality revenue data directly.

Trimark’s SCME MDMA Services

  • SQMD initiation
  • SQMD plan development
  • SQMD implementation
  • Ongoing SCME MDMA services
  • Meter maintenance services
  • Controls
  • Incentive program data reporting services (optional)
  • Meter data communications services (optional)


Based on Trimark’s certifications as a MDMA throughout California, Trimark provides MDMA services to meet this requirement with a Scheduling Coordinator agreement. Trimark can ensure resource owners that Settlement Quality Meter Data (SQMD) will be submitted in a manner that avoids Rule of Conduct Penalties for late or inaccurate SQMD.

Trimark’s process produces meter data that is acceptable for billing or generation settlements.
