Power Lines and Pipeline Corrosion – A Quick MDN Primer

MDN told you yesterday about a story in the anti-drilling Albany Times Union newspaper that seeks to spread FUD–fear, uncertainty and doubt–about the proposed Kinder Morgan Northeast Extension Direct pipeline (see Albany Times Union Says Electric Lines will Corrode NED Pipeline). The meme trying to be spread by the TU is that if Kinder moves forward with a plan to co-locate the pipeline along miles and miles of high voltage power line corridors, the power lines will eat away the pipeline and turn it into a ticking time bomb that will one day explode. That’s our words, not the TU’s words, but that’s clearly the impression the TU reporter attempts to convey in the article. We poked fun at the notion that electric lines corrode pipelines. However, it does happen! No less than three sharp MDN readers, one of them from the federal government, emailed with information about the phenomenon of pipeline corrosion from AC power lines. The upshot is that a) this is a known issue, b) there are ways to safely mitigate any potential corrosion from AC power lines, and c) pipelines have been co-located along power line corridors for decades–safely…
