Indianapolis Power and Light Co. is taking a closer look at its underground network following a series of explosions in downtown Indianapolis. The latest happened Tuesday when a faulty underground cable failed, sparking a small explosion near the governor's office in the Statehouse. Several staff members were evacuated and fire crews put out a small blaze. IPL said Wednesday it will accelerate plans to inspect its underground system, including key equipment, vaults and other infrastructure.
