Establishes a hydroelectric power tax credit

This bill creates a tax credit allowing taxpayers to offset 50% of licensing or relicensing fees paid to state or federal agencies for hydroelectric power projects. It directly affects businesses and developers subject to taxes under specific sections of the tax code (articles 9, 9-A, 22, and 33). The credit can be applied against income taxes, with unused portions carried forward to future tax years if it reduces taxes below minimum thresholds. The bill modifies multiple tax code sections to implement this credit and its carryover rules.
