Net-Metering Protocols—Spring 2013 The supplier’s anniversary month would be different from the Utilities anniversary month. Since PSE&G is bill ready the supplier is responsible to calculate the over generation credit to the Customer on the anniversary month. 5 Are there any notable Consolidated billing No No In a dual billed There are no differences between and dual billing should account, notable differences consolidated billing and work the same way. adjustments are dual billing situations? PSE&G will accept made immediately credit or negative 810 and a corrected bill Invoice transactions to accommodate any created. For credits due to the over consolidated billing, generated amount. there is a delay waiting for customer charges before adjustments and a corrected bill is created.
