When an account that has multiple electric service points bills, why can the billing period be slightly different for each of the service points?
Regardless of the number of service points on an account, an Ameren delivery services bill and/or the corresponding EDI810 and EDI867 transactions are always produced together when the account bills. However, the service points that make up the account may have slightly different billing periods since service points bill independently of each other. For example, a DS5 lighting service point often bills on the first day of the four business day Ameren billing window. However, DS1, DS2, DS3, and DS4 service points may or may not bill on the first day of the Ameren billing window.
How many EDI 867M transactions will be produced when a RES-supplied account bills?
EDI 867M transactions are created per service point. So, if an account has one electric service point, then only one EDI 867M will be produced each time that the account bills. If an account has a DS2 service point as well as a DS5 (lighting) service point, then two EDI 867M transactions will be produced each time the account bills. Note that the number of meters associated with a service point has no impact on the number of EDI 867M transactions that are produced.
How is a subtractive meter denoted in the EDI 867 transaction?
There are a relatively small number of Ameren Illinois accounts that have one or more subtractive meters on them. The designation in the EDI 867 that a meter’s usage is subtractive can be found on the REF segment when element one is “JH” and element two is “S” (the “S” stands for “Subtractive”). Thus, a subtractive meter is denoted in the EDI 867 transaction as follows: REF*JH*S.
Conversely, a typical non-subtractive meter is noted as REF*JH*A in the EDI 867 transaction (where the “A” stands for “Additive”).
How may a RES change the billing option for an account that it is supplying?
A RES can change the billing option for an account via the EDI 814C transaction. The billing option change will always be effectuated for the billing period after the date requested in the EDI 814C transaction.
How is interval meter data handled in the EDI 867 transaction on the spring forward and fall back days (the days leading into and out of Daylight Saving Time)?
