The Ohio Electronic Data Interchange Working Group (OEWG), formerly known as the Operational Support Data Exchange Workgroup, develops EDI transaction standards and procedures for customer choice in Ohio's electric service industry.
About the OEWG
In 1999, legislation was enacted to transform Ohio’s electric industry from a monopoly to a competitive market for retail electric generation service beginning in 2001. Pursuant to this legislation, the Commission's order of November 30, 1999 in Case No. 99-1141-EL-ORD, directed Ohio's investor-owned electric utilities and interested stakeholders to participate in a taskforce for the development of uniform business practices and electronic data interchange (EDI) standards.
