(10) "Siting area," that area within ten miles in any direction of a proposed energy conversion facility, AC/DC conversion facility, or which is determined by the commission to be affected by a proposed energy conversion facility;
(11) "Trans-state transmission facility," an electric transmission line and its associated facilities which originates outside the State of South Dakota, crosses this state and terminates outside the State of South Dakota; and which transmission line and associated facilities delivers electric power and energy of twenty-five percent or less of the design capacity of such line and facilities for use in the State of South Dakota;
(12) "Utility," any person engaged in and controlling the generation or transmission of electric energy and gas or liquid transmission facilities as defined by § 49-41B-2.1;
(13) "Wind energy facility," a new facility, or facility expansion, consisting of a commonly managed integrated system of towers, wind turbine generators with blades, power collection systems, and electric interconnection systems, that converts wind movement into electricity and that is designed for or capable of generation of one hundred megawatts or more of electricity. A wind energy facility expansion includes the addition of new wind turbines, designed for or capable of generating twenty-five megawatts or more of electricity, which are to be managed in common and integrated with existing turbines and the combined megawatt capability of the existing and new turbines is one hundred megawatts or more of electricity. The number of megawatts generated by a wind energy facility is determined by adding the nameplate power generation capability of each wind turbine;
(14) "Solar energy facility," a new facility, or facility expansion, consisting of a commonly managed integrated system of solar panels, power collection systems, electric interconnection systems, and associated facilities, that converts solar energy into electricity and is designed for or capable of generating one hundred megawatts AC or more of electricity. A facility expansion includes the addition of new solar panels, designed for or capable of generating twenty-five megawatts AC or more of electricity, that are to be managed in common and integrated with existing solar panels, and the combined megawatt capability of the existing and new solar panels is one hundred megawatts AC or more of electricity.

49-41B-2.1. Transmission facility defined.
For the purposes of this chapter, a transmission facility is:
(1) An electric transmission line and associated facilities with a design of more than one hundred fifteen kilovolts. However, if the transmission line is less than two thousand six hundred forty feet, does not cross any public highway, and eminent domain is not used to obtain right of way, the transmission line is not a transmission facility for purposes of this chapter; or
(2) A gas or liquid transmission line and associated facilities designed for or capable of transporting coal, gas, hydrogen, liquid hydrocarbons, liquid hydrocarbon products, or carbon dioxide, excluding any gas or liquid transmission lines or associated facilities which meet any of the following criteria:
(a) Lines or facilities that are used exclusively for distribution or gathering;
(b) Steel pipe and associated facilities that cannot be operated at a hoop stress of twenty percent or more of specified minimum yield strength as defined by 49 C.F.R. § 192.3 (January 1, 2024) or plastic pipe and associated facilities that cannot be operated at a design pressure of fifty percent or more as determined by the formula specified in 49 C.F.R. § 192.121 (January 1, 2024); or
(c) Pipe which has nominal diameter of less than four inches and not more than one mile of the entire line is constructed outside of public right-of-way.
Nothing in this section precludes a utility from applying to the commission for a permit for the construction of an electric transmission line and associated facilities with a design of one hundred fifteen kilovolts or less. The transmission line and associated facilities is a transmission facility for the purposes of this chapter.

49-41B-2.2. Modified facility defined.
For the purposes of this chapter, a facility is considered to be modified if:
(1) A gas or liquid transmission line that did not meet the definition of a transmission facility prior to building the line is to be modified in such a way that the line will meet the definition of a transmission facility after the modification is complete. No permit is required for steel pipe and associated facilities, as described in subsection 49-41B-2.1(2)(b), operating on July 1, 2010, that have been historically calculated at an ongoing constant pressure of less than twenty percent of specified minimum yield strength unless the pipeline operator intends to increase the ongoing constant pressure to twenty percent or more. No permit is required for plastic pipe and associated facilities, as described in subsection 49-41B-2.1(2)(b), operating on July 1, 2010, that have been historically calculated at an ongoing constant pressure of less than fifty percent of the design pressure unless the pipeline operator intends to increase the ongoing constant pressure to fifty percent or more;
(2) An electric transmission line that does not meet the definition of a transmission facility prior to building the line is to be modified in such a way that the line will meet the definition of a transmission facility after the modification is complete or the nameplate carrying capacity of an electric transmission facility is to be increased by an additional twenty kilovolts or greater; or
(3) The nameplate generating capacity of an energy conversion facility is to be increased by a net additional one hundred megawatts or greater.
