Rule 24 Data ProcessA Simple Example

Introduction
In this example we start with a DRP that is registered with the CPUC and has a DRP service agreement.
We will follow a single, individually metered service account, a 300kW Supermarket, from first contact by a DRP to meter data delivery to CAISO. Our example will illustrate the steps involved and use of forms as well the key players.
Then we will follow another single, individually metered service account, a 300kW Supermarket, from first contact by a DRP to meter data delivery to CAISO.
Our example will ultimately illustrate the challenges to provide the necessary information required.

Pacific Gas and Electric Company, San Diego Gas & Electric Company, and Southern California Edison Company, as the Meter Data Management Agent, are responsible for providing the actual Settlement Quality Meter Data to the demand response provider’s Scheduling Coordinator to facilitate final data submission in accordance with the CAISO tariff.

RQMD is a routine processthat MDMAs perform.

SQMD requires meter data plus registration data. MDMAs provide the meter data, but do not yet have access to the DRS registration data.

For ExampleFor Example
• DRP (Muir’s DRP Co)– Signs up a supermarket– Registers the supermarket in Resource B – Registration B1
• Processes– UDC CISR form– CAISO Demand Response System (DRS)
• UDC “ok”• LSE “ok”• CAISO “ok”
– Meter Data• MDMA1
– RQMD– SQMD

Example continuedExample continued
• DRP (Muir’s DRP Co)– Signs up another supermarket
• MDMA2
– Also registers the supermarket in Resource B – New Registration B2
• Processes– UDC CISR form– CAISO DRS
• UDC “ok”• LSE “ok”• CAISO “ok”
– Meter Data• MDMA2
– RQMD– No SQMD (different MDMAs)

Muir Co establishes Registration B1, containing one SA (Fantastic Basket). In this case SQMD = RQMD.

For an MDMA to keep track of the registration changes, it will need access to the CAISO’s DRS.
The addition of “Play Foods” requires a new registration B2. Here the RQMD is not the same as SQMD.

There is a need to consolidate the RQMD information from the MDMAs as defined by the registrations from the DRS to produce the SQMD. This could be done by the DRP or a consolidating MDMA.
The DRS information is critical for producing the SQMD necessary for supporting each registration. There may be times where there are multiple registrations requiring SQMD for the same DR resource.
