IPL Downtown Underground Network

Beneath the streets of downtown Indianapolis is a complex system of transformers, cables and control equipment that make up the underground network. IPL’s underground facilities are also joined by infrastructure from other utilities, including steam, water, natural gas, storm and sanitary sewer, fiber optics, cable TV and telecommunications. This complex infrastructure serves more than 2,600 customers with power. IPL’s skilled underground technicians work every day to maintain a safe and reliable network.   

IPL takes steps year-round to inspect and maintain our downtown network. The protective initiatives we’ve put in place include inspections of manholes every three years and vaults every two years. In March of 2015, IPL announced efforts to accelerate the installation of locking manhole covers in the downtown area. These covers are designed to pop up only a few inches if there is ever an over-pressurization incident in a manhole. As of mid-November 2015 all manhole covers in the downtown network have been replaced with locking covers.  To see the areas of downtown Indianapolis where these lids have been installed, click here

The safety of our community, customers and employees remains IPL’s top priority. We cannot completely eliminate the risk of incidents occurring where there is underground electrical infrastructure. However, we are committed to taking the necessary actions to reduce the likelihood and impact of any future occurrences. Here is a snapshot of our completed and ongoing efforts.
