The Texas Interconnection is one of the three minor Alternating Current (AC) Power Grid s in North America. The other two minor interconnections are the Québec Interconnection and the Alaska Interconnection . The two major interconnections are the Eastern Interconnection and the Western Interconnection . All of the electric utilities in the Texas Interconnection are electrically tied together during normal system conditions and operate at a synchronized frequency operating at an average of 60Hz. The Texas Interconnection covers most of the State of Texas . Interconnections can be tied to each other via High Voltage Direct Current power transmission lines which permit a controlled flow of energy while also electrically separating the synchronized AC systems of each side. The Texas Interconnection is tied to the Eastern Interconnection with two High Voltage Direct Current (DC) ties, although there are a handful of intermediate voltage Alternating Current (AC) ties to the Eastern Interconnection which are normally opened but available for emergency purposes. The Texas Interconnection also has ties to non-NERC systems in Mexico , including a high voltage DC tie. SEE ALSO
