Describes methods of electrical coordination between pipelines and alternating current (ac) supply lines having line-to-line voltages greater than 60 kV that are simultaneously or separately installed as follows: a) a pipeline located on a power line right-of-way or a power line located on a pipeline right-of-way; b) a pipeline right-of-way located parallel to a power line right-of-way, or vice versa, where the adjacent right-of-way boundaries are within 300 m of each other; and c) laterals and extensions to the pipelines described in Item (a) or (b).
