26 Del. C. § 204

(a) The Commission may, after hearing, upon notice, by order in writing, require every public utility to establish, construct, maintain and operate any reasonable extension of its existing facilities where, in the judgment of the Commission, such extension is reasonable and practicable and will furnish sufficient revenue to justify the construction and maintenance of the same, and when the financial condition of the public utility reasonably warrants the original expenditures required in order to make and operate such extension; provided, however, the Commission shall consider, among other things, the size and amount of additional and potential customers to be served, whether the new customers will contribute to any capital expenditures required by the extension and whether the public utility must borrow funds to provide the extension of service.

(b) Notwithstanding any other provision of law, a telecommunications service provider is not required to establish, construct, maintain, operate or extend its existing facilities where the potential customers to be served have service available from 1 or more alternative providers of wireline or wireless communications. Further, notwithstanding any other provision of law, if the Commission makes a determination under subsection (a) of this section requiring such extension, a telecommunications service provider may fulfill such obligation through the use of any and all available wireline, wireless or other technologies. The use of wireline, wireless or other technologies may not be construed to grant any additional jurisdiction or authority to the Commission over such technologies.
