Duke Energy Corp. subsidiary Duke Energy Ohio Inc. has submitted a notice of intent to Public Utilities Commission of Ohio to file for a regulatory review of its distribution rate on March 2.

Duke Energy completed the deployment of its smart grid technologies, including smart meters, communications nodes and self-healing networks in 2015 to ensure better distribution, it said in a Feb. 1 news release.

Most of the costs incurred during the deployment have already been recovered from a separate rider on customers' bills.

The PUCO will review the distribution rates and decide whether to eliminate the rider and include any remaining costs in base rates.

If approved, the reviewed tariff will take effect in 2018 and raise electricity bills approximately by $1.15, less than 1%, based on a residential customer using 1,000 kWh per month, Duke Energy said.

The PUCO last approved a rate increase of $49 million on Duke Energy tariffs in 2013.
