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 (at 26-27), 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.
On May 15, 2000, the Operational Support Planning for Ohio Taskforce (OSPO) and Data Exchange Work Groups, which were comprised of representatives from each Ohio electric distribution utility, potential marketers and generation suppliers, and other interested parties, filed a stipulation (word version) and pro forma certified supplier tariff (word version) in Case No. 00-813-EL-EDI which were subsequently adopted by the Commission on July 19, 2000. The OSPO Taskforce was active until 2002. (Download the December 19, 2000 through November 22, 2002 OSPO Meeting Summaries in .ZIP format.)
The OSPO Data Exchange Workgroup (OSPOData) was a subgroup of the OSPO Taskforce charged with the development and implementation of the EDI transaction codes and rules to enable electric retail customers to choose an alternative generation supplier. The OSPOdata group was active from 2000 until 2004 (Download the OSPOdata Meeting Minutes from 2000 through 2004 in .ZIP format), and was reconstituted in 2010 under the OEWG name to update EDI documentation and resolve issues.
