Imposes 10 percent electric public utility windfall surtax on taxpayers with allocated taxable net income in excess of $10 million under CBT.

This bill imposes a 10% surtax on electric public utilities with allocated taxable net income exceeding $10 million annually. The surtax applies in addition to existing corporation business taxes and must be paid by qualifying utilities. All revenue collected, except for constitutionally dedicated funds, is required to be annually appropriated to the Board of Public Utilities to fund existing utility assistance programs like the Winter Termination Program and Lifeline Credit Program. The bill explicitly prohibits utilities from passing the cost of this surtax to ratepayers through future rate increases.
