  • Electric choice: customers who have individually signed a contract or agreement with a competitive retail electric service (CRES) provider, and purchase electric generation service from that competitive supplier under the terms and conditions of the agreement or contract; or, are part of an electric aggregation group purchasing electric supply from a CRES provider.
  • Electric non-choice: customers who purchase electric generation service under arrangements made by the electric distribution utility (EDU), known as the standard service offer (SSO).
  • Natural gas choice: customers who have individually signed a contract or agreement with a competitive retail natural gas service (CRNGS) provider, and purchase gas supply from that competitive supplier under the terms and conditions of the agreement or contract; or, are part of a gas aggregation group purchasing gas supply from a CRNGS provider.
  • Natural gas non-choice: customers who purchase natural gas under arrangements made by the local distribution company (LDC), known as the standard choice offer (SCO) or gas cost recovery (GCR) offer.



Ohio Administrative Code 4901:1-25-02 requires EDUs, CRES marketers and aggregators, and governmental aggregators to report monthly market monitoring information to the PUCO on a quarterly basis. Specifically:

  • 4901:1-25-02(A)(2) for electric utilities (known as 1.2 data)
  • 4901:1-25-02(A)(3) for certified retail electric services companies (1.3 data)
  • 4901:1-25-02(A)(4) for certified aggregators and governmental aggregators (1.4 data)

Additionally, Ohio’s EDUs submit similar data pursuant to Ohio Revised Code 4935 and Ohio Administrative Code 4901:5 (known as SE-1 or forecasting data). The PUCO may use any of these data sources in assessing whether effective competition exists for retail electric service in Ohio.

Ohio’s LDCs and CRNGS marketers and aggregators are not subject to the same market monitoring reporting requirements as those participating in the electric choice program. However, Ohio’s LDCs report data pursuant to Ohio Revised Code 4935 and Ohio Administrative Code 4901:5 (known as SG-1 or forecasting data) and additionally natural gas choice data voluntarily. The PUCO uses these data sources to compile the natural gas choice dashboard. 

Ohio's retail market measurements

Effective competition includes the existence of the following characteristics: (1) participation in the market by multiple sellers so that an individual seller is not able to significantly influence the market price of the commodity; (2) participation in the market by informed buyers; (3) lack of substantial barriers to supplier entry into and exit from the market; (4) lack of substantial barriers that may discourage customer participation in the market; and (5) sellers offering buyers a variety of products.

Pursuant to Ohio Revised Code 4928.06, the PUCO considers various factors in determining whether there is effective competition in the provision of retail electric service, including: (1) number of certified CRES providers statewide and by EDU service territory; (2) number of active CRES providers by EDU service territory; (3) number of customers shopping by class and by EDU service territory; (4) percentage of load shopping by class and by EDU service territory; (5) all EDUs having at least structural separation; (6) 100 percent of the SSO load procured via a competitive process for all EDUs; and (7) whether customers are engaged and informed about the products and services they receive.


These retail market measurements are intended to present a broad picture of the state of retail competition in Ohio. Appropriate calculations made for other purposes may be based on different data, and may yield different results. No individual metric is determinative of the lack of effective competition or implies that action needs to be taken. Rather, the collective results of the metrics can be used for monitoring purposes to evaluate the effectiveness of competition at a particular time.
