Duke estimates that by 2020, customers will save an average of about $7, or 5.6 percent, on their average monthly electric bill.

Indiana's largest electric utility company credits the 2017 GOP tax overhaul for what it estimates will be about $7.33 savings per month for the average customer using 1,000 kilowatt-hours a month.

State environmental officials must approve Duke's disposal plans, which include testing the site's groundwater monitoring wells at least twice a year.
