IPL to replace 100 manhole covers

July 8, 2011

Indianapolis Power and Light said it has a new plan to prevent underground electrical explosions that send manhole covers several feet into the air. After a six-week investigation into several such events, IPL said it will replace about 100 manhole covers in the downtown area and begin inspecting manholes at least once every three years instead of five. IPL said its investigation didn't turn up a system-wide problem with manholes, but discovered several problems with the manholes where explosions took place.
