The state of Indiana is filing a motion to stop Indianapolis Power and Light Company’s request to raise customer rates. IPL is asking for a rate hike of more than $67 million a year. The Indiana Utility Consumer Counselor wants the state regulatory commission to first finish an investigation into last week’s underground explosions that sent manhole covers flying into the air across downtown Indianapolis. They say the incident is of important significance to both rate payers and to the public interest at large. As of now, IPL has brought in contractors to help inspect the manhole covers because each one needs to be inspected before the Final Four weekend–an NCAA event that will be hosted in the city drawing thousands to downtown. About 50 workers have arrived to answer the power company’s call for help from Chicago, Dayton and Cincinnati. They will check cables, vaults and other equipment. While they’re doing that, IPL crews will continue to repair damage from last week’s blasts.
