Information for Retail Gas Suppliers

The PUCO, Ohio utilities and interested stakeholders have adopted Electronic Data Interchange (EDI) as the standard electronic communication method for exchanging data between utilities and certified suppliers. EDI is the standard communication method between the certified supplier and Duke Energy Ohio for end-use customer enrollment, drop, reinstate, change, billing, payment, account maintenance, transfer of usage information and other business transactions.

What Is EDI?

EDI is the electronic exchange of business information in a standard format between certified suppliers and Duke Energy Ohio. For customer choice, certified suppliers and Duke Energy Ohio will communicate through EDI for end-use customer enrollments, drops, billing, payments, account maintenance, transfer of usage information and other business transactions. EDI transactions are designed to automate and streamline the typical repetitive business transactions that occur between Duke Energy Ohio and a certified supplier. EDI has its own set of terms that are specific to EDI. A list of these terms and specific definitions can be found in Appendix C: Detailed EDI Information.

What is a Trading Partner?

For customer choice, Duke Energy Ohio and certified suppliers are trading partners. Certified suppliers must have a signed Trading Partner Agreement in order to transact business directly with Duke Energy Ohio using EDI. For the EDI Trading Partner Agreement Form, see Appendix E: Registration and Participation Forms.

How does EDI work?

EDI passes data from Duke Energy Ohio's systems to the certified supplier's systems via North American Energy Standard Board (NAESB) Electronic Delivery Mechanism (EDM) data transport protocols using transaction sets and EDI translators.
- The EDI translator is software used to translate data to a corporate proprietary format and vice versa.
- A Transaction Set is the EDI term used for a business document. Duke Energy Ohio uses transaction set guidelines established by the Ohio EDI Working Group (OEWG). Members of the OEWG include representatives from the PUCO, Ohio utilities, electric suppliers and the EDI service providers. These guidelines provide a standard methodology for conducting business in an electronic environment in Ohio.
Summary of EDI Transactions Sets

The business transaction sets between Duke Energy Ohio and the certified supplier are:
- Ohio814E Enrollment/Historical Usage Request
  An enrollment request is used for Duke Energy Ohio to process an end-use customer’s request for electric service from a specific certified supplier. A certified supplier may also request historical usage separate from the enrollment process. A request for historical usage notification (Ohio814E for history) is used.
- Ohio814C Change Request
  The change request is used for Duke Energy Ohio to notify a certified supplier of a change in end-use customer information. The change request is also used by a certified supplier to notify Duke Energy Ohio of a change in certain end-use customer information.
- Ohio814D Drop Request
  The drop request is used by a certified supplier to notify Duke Energy Ohio that it is discontinuing supply services to an end-use customer. In this case, Duke Energy Ohio will return the end-use customer to standard service offer, provided there have been no enrollment requests received from other suppliers. The drop request is also used by Duke Energy Ohio to process an end-use customer’s request to return to a previous supplier or to standard service offer. When Duke Energy Ohio receives an enrollment from a new supplier, Duke Energy Ohio will send a drop request to the existing supplier. Duke Energy Ohio will also use a drop request when it disconnects service to an end-use customer served by a certified supplier. If the end-use customer wishes to select another certified supplier, they must contact that certified supplier.
- Ohio814R Reinstate Request
  Duke Energy Ohio will use this transaction to reinstate an end-use customer with a previous certified supplier. This scenario assumes that Duke Energy Ohio has received an enrollment notification from a certified supplier for an end-use customer and that the end-use customer has requested that Duke Energy Ohio rescind the request. The Ohio814R is also used for reinstating an active supplier from a pending drop that was sent in error to Duke Energy Ohio by the certified supplier. The certified supplier who originally sent the 814D may submit an 814R to rescind the 814D.
- Ohio814 Response
  An Ohio814 Response is used to notify a certified supplier of Duke Energy Ohio's acceptance or rejection of an enrollment request, which includes notice of effective date, plus code of reason for rejection.
- Ohio867 Meter Data
  When historical usage data is requested, it will be sent by Duke Energy Ohio using the historical usage transaction. The Ohio867 transaction is used to transmit end-use customer usage information as captured from the meter for 12 months of history and for ongoing monthly metered data. It is also used to transmit unmetered usage for non-metered accounts.

Duke Energy/State of Ohio Differences in Standards

Listed below are items that represent differences between Duke Energy Ohio's processes and Ohio state standards:
- The state standard to validate EDI Transactions requires two validation points, end-use customer account number and the first four characters of the customer's last name or business name. Duke Energy Ohio will utilize only one validation point – end-use customer's account number
- The Ohio814 enrollment transaction has a field for the certified supplier to indicate a budget billing dollar amount for the supplier's portion of the bill. Duke Energy Ohio does not support a supplier requested budget billing amount. When customers request budget billing from Duke Energy, the asking amount on Duke Energy bill incorporates a budget billing amount for the certified supplier's portion of the bill.
- Duke Energy Ohio limits the number of rates a certified supplier may assign to an account to one, no matter how many meters the account may have. If a supplier submits multiple rates for the same enrollment or change request, Duke Energy Ohio will select the last rate on the request and use it for the entire account. This will be reflected in the EDI response document sent back to the supplier.
- Duke Energy Ohio will charge certified suppliers a fee for ongoing detailed monthly interval meter data and 12-month detailed data. A supplier who does not want to receive the ongoing detailed interval data and the corresponding charge should request summary data only on the original enrollment transaction or after enrollment via a change transaction.
