The tax rate shall be at an amount equal to two and six-tenths (2.6) percent of the gross income from the business activity upon every person engaging or continuing in the business of producing, providing or furnishing utility services, including electricity, electric lights, current, power, gas (natural or artificial), or water to:
   (1)   Consumers or ratepayers who reside within the city.
   (2)   Consumers or ratepayers of this city, whether within the city or without, to the extent that this city provides such persons utility services, excluding consumers or ratepayers who are residents of another city or town which levies an equivalent excise tax upon this city for providing such utility services to such persons.
   (b)   Exclusion of Certain Sales of Natural Gas to a Public Utility. Notwithstanding the provisions of subsection (a) above, the gross income derived from the sale of natural gas to a public utility for the purpose of generation of power to be transferred by the utility to its ratepayers shall be considered a retail sale of tangible personal property subject to sections 19-460 and 19-465, and not considered gross income taxable under this section.
   (c)   Resale Utility Services. Sales of utility services to another provider of the same utility services for the purpose of providing such utility services either to another properly licensed utility provider or directly to such purchaser's customers or ratepayers shall be exempt and deductible from the gross income subject to the tax imposed by this section, provided that the purchaser is properly licensed by all applicable taxing jurisdictions to engage or continue in the business of providing utility services, and further that the seller maintains proper documentation, in a manner similar to that for sales for resale, of such transactions.
   (d)   Reserved.
   (e)   Exclusion of Sales of Utility Services to Nonprofit Primary Health Care Facilities.
