WILMINGTON, Del. — Delaware’s Public Advocate says the new tax law recently signed by President Donald Trump should lead to lower water and electricity bills.

The News Journal in Wilmington reported Friday that Delaware Public Advocate Andrew Slater is charged with lobbying on behalf of ratepayers. He filed a petition Thursday with state regulators arguing that lower corporate tax rates will benefit utilities. Slater said they should pass on those savings to consumers.

Regulators and at least one utility company agree, at least in principle. But they say it may take a year of negotiations to determine how much savings there will be. There are also questions about whether consumers will see lower rates or new and better infrastructure.
