The Delaware Public Service Commission on Jan. 31 approved additional rate cuts for the state’s regulated utilities to account for over-collection associated with the federal tax reforms that slashed corporate income tax rates to 21 percent from 35 percent, effective Jan. 1, 2018.

• Overall rate reductions to regulated utilities to flow back excess taxes to customers total more than $18 million.
• The approval includes in 1.5 percent savings in residential bills of Chesapeake Utilities’ customers.
• Last June, the commission authorized a settlement resulting in a 1.4 percent decrease in costs for customers of Delmarva Power, a subsidiary of Exelon Corp., as result of the tax cut reforms, instead of a 4.7 percent increase the company initially proposed in its rate request.
