UGI Corp. detailed plans to cut customer bills at its UGI Central Penn Gas Inc. and UGI Penn Natural Gas Inc. utilities in Pennsylvania as a result of federal corporate tax cuts and lower purchased gas costs.

Under a plan filed with the Pennsylvania Public Utility Commission, UGI Penn's residential customers would see bills decrease by an average of $2.01 per month, to $89.14, starting July 1, according to a June 15 news release. The utility also projected a 2.8% decrease due to lower gas costs starting Dec. 1.

The utility serves 172,000 customers in northeast Pennsylvania.

UGI Central Penn would implement a tax relief credit averaging $4.50 per month, reducing the average residential bill to $85.84 starting July 1, according to a separate news release. UGI Penn also projected a 3.7% decrease starting Dec. 1 from reduced gas costs.

The PUC ordered utility companies in Pennsylvania to provide a credit to customers based on the federal tax overhaul in 2017, which reduced corporate tax rates to 21% from 35%.

UGI Central Penn Gas serves about 83,000 customers in 37 Pennsylvania counties.
