Some RTOs also have retail-level competition and consumer choice of electricity providers.

Each ISO has its own FERC-approved governance structure. An ISO/RTO does not own any of the transmission or generation assets it manages. An RTO also: assures non-discriminatory open access to transmission forecasts, schedules and dispatches generation to meet demand manages interconnection of new generation administers the region's competitive wholesale electricity markets monitors the fairness and neutrality of markets for all participants and provides reliability planning for the bulk electricity system. RTOs (or ISOs) вЂ“ 7 Regional Transmission Pools with Wholesale Electricity MarketsД®ach ISO or RTO (they are very similar) is an independent body that operates the high-voltage Transmission grid of all Transmission owners within its region. ERCOT (most of Texas - 1 balancing authority - within a single state, so not regulated by the FERC).

Western Interconnection (37 balancing authorities, including 3 in Canada and Mexico).Eastern Interconnection (36 balancing authorities, including 5 in Canada).ISOs/RTOs also oversee organized wholesale electricity markets, whereas most individual utilities are vertically-integrated monopolies that control all electricity generation, transmission, and distribution within their territory. Most Balancing Authorities are individual utilities, while most of the total power flow is managed by 7 larger regional entities (ISOs or RTOs) that perform the balancing function. 'Balancing Authorities' that each operate a portion of the grid, balancing supply and demand at all times, and assuring Federal reliability standards are met. The physical electrical system consists of 3 'Interconnections' that are largely independent with minimal power exchange (colored regions in figure).
