Minn. Stat. § 412.351: COMMISSION, JURISDICTION.

The council shall, in the ordinance establishing the commission, decide which of the following public utilities shall be within the commission's jurisdiction: (1) the city water system; (2) light and power system, including any system then in use or later acquired for the production and distribution of steam heat; (3) gas system; (4) sanitary or storm sewer system or both, including the city sewage disposal plant; (5) public buildings owned or leased by the city; (6) district heating system. As used subsequently in sections 412.351 to 412.391, the term "public utility" means any water, light and power, gas or sewer system, or public buildings thus placed by ordinance under the jurisdiction of the public utilities commission. Any public utility not placed under the jurisdiction of the public utilities commission by the ordinance establishing the commission may be placed under the jurisdiction of the commission by an amendment to the original ordinance.
