RTOs offer regional wholesale electric transmission services under one tariff. [ 8 ] FERC first required transmission owners to provide non-discriminatory access to their lines in Order Nos. 888 and 889 , building on the model it had used to require interstate natural gas pipelines to provide access to pipeline capacity.
The Texas Interconnection is one of the three minor alternating current (AC) power grids in North America. All of the electric utilities in the Texas Interconnection are electrically tied together during normal system conditions, and they operate at a synchronized frequency operating at an average of 60 Hz.
