Scheduling Coordinator Metered Entity

Participating in the CAISO Market

Resources that participate in the CAISO market, be they generation or load, establish their metering requirements as being either a CAISO Metered Entity (CAISO ME) or a Scheduling Coordinator Metered Entity (SCME). Until recently, the majority of the SCMEs have been resources representing load, both bundled and direct access customers. However, with changes to the CAISO Tariff, opportunities have opened for more to participate as SCMEs in the CAISO market.

Is an SCME Right for You?

Entities that CAISO will consider for can be SCMEs include new load entities, participating generators, demand response resources, Energy Imbalance Market (EIM) participants and Community Choice Aggregations (CCA). An SCME is responsible for obtaining, processing and submitting their Settlement Quality Meter Data (SQMD) directly to the CAISO for market settlement. To assure the quality and integrity of the SQMD being submitted, CAISO requires a SQMD Plan.

The SQMD Plan, once approved by CAISO, provides information of the entities’ equipment, processes, testing and maintenance that assures that the SQMD provided to CAISO will be accurate and correct. Specifically, the SQMD Plan requires the participant to provide information on the market resource attributes, a description of the meter data processing, plans for audits and tests, and metering device details. Unique for Demand Response resources, a similar plan – a Demand Response Template – is used to document the method for baseline and performance measurements.
