    16. 16. Use Case 1: Fixed Submeter Electricity Usage Data BillingUtility = Electric Commodity Provider (One to One EVSP) Master Meter Usage Submeter UsageCustomer of Record for the Fixed Submeter is the Premise Owner Premises Usage Premises 1 PU1 Utility Systems Stagin MM1 FSubA Open Back g DMA EV Office FSubA1 Server AMI Implications – Assumes 3rd Party sends data from their Data Management Agent (DMA) to the utility via the OpenEV interface OpenEV – Requires 3-way association among customer, 3rd party, and utility prior to accurate subtractive billing (i.e. no ad-hoc associations) – Submeter adheres to the same certification and requirements as a utility master meter based on national standards – OpenEV standard must be established, and 3rd Party DMA is certified to it – AMI network is not used to transport submeter data Project Green On Ramp Paul Stith SUM – Sustainable Unlimited Mobility December 10, 2011 16
