INDIANAPOLIS (AP) — Duke Energy asked state regulators Friday to approve a nearly $2 billion upgrade of its Indiana electric grid, improvements the utility said would help reduce power outages by adding “self-healing” smart technologies to the grid.

Duke is Indiana’s largest electric utility, with more than 800,000 customers. The Charlotte, North Carolina-based company asked the Indiana Utility Regulatory Commission in Friday’s filing to approve a seven-year, $1.9 billion plan to replace substations, utility poles, power lines, transformers and other aging parts of its electric grid. That upgrade would include installing new, advanced utility meters the company said would mean fewer and shorter electrical outages for its customers.
