Section 62-9-1 - New construction; ratemaking principlesA. No public utility shall begin the construction or operation of any public utility plant or system or of any extension of any plant or system without first obtaining from the commission a certificate that public convenience and necessity require or will require such construction or operation. This section does not require a public utility to secure a certificate for an extension within any municipality or district within which it lawfully commenced operations before June 13, 1941 or for an extension within or to territory already served by it, necessary in the ordinary course of its business, or for an extension into territory contiguous to that already occupied by it and that is not receiving similar service from another utility. If any public utility or mutual domestic water consumer association in constructing or extending its line, plant or system unreasonably interferes or is about to unreasonably interfere with the service or system of any other public utility or mutual domestic water consumer association rendering the same type of service, the commission, on complaint of the public utility or mutual domestic water consumer association claiming to be injuriously affected, may, upon and pursuant to the applicable procedure provided in Chapter 62, Article 10 NMSA 1978, and after giving due regard to public convenience and necessity, including reasonable service agreements between the utilities, make an order and prescribe just and reasonable terms and conditions in harmony with the Public Utility Act to provide for the construction, development and extension, without unnecessary duplication and economic waste.B. If a certificate of public convenience and necessity is required pursuant to this section for the construction or extension of a generating plant or transmission lines and associated facilities, a public utility may include in the application for the certificate a request that the commission determine the ratemaking principles and treatment that will be applicable for the facilities that are the subject of the application for the certificate. If such a request is made, the commission shall, in the order granting the certificate, set forth the ratemaking principles and treatment that will be applicable to the public utility's stake in the certified facilities in all ratemaking proceedings on and after such time as the facilities are placed in service. The commission shall use the ratemaking principles and treatment specified in the order in all proceedings in which the cost of the public utility's stake in the certified facilities is considered. If the commission later decertifies the facilities, the commission shall apply the ratemaking principles and treatment specified in the original certification order to the costs associated with the facilities that were incurred by the public utility prior to decertification.C. The commission may approve the application for the certificate without a formal hearing if no protest is filed within sixty days of the date that notice is given, pursuant to commission order, that the application has been filed. The commission shall issue its order granting or denying the application within nine months from the date the application is filed with the commission. Failure to issue its order within nine months is deemed to be approval and final disposition of the application; provided, however, that the commission may extend the time for granting approval for an additional six months for good cause shown.D. In an application for a certificate of public convenience and necessity for an energy storage system, the commission shall approve energy storage systems that:(1) reduce costs to ratepayers by avoiding or deferring the need for investment in new generation and for upgrades to systems for the transmission and distribution of energy;(2) reduce the use of fossil fuels for meeting demand during peak load periods and for providing ancillary services;(3) assist with ensuring grid reliability, including transmission and distribution system stability, while integrating sources of renewable energy into the grid;(4) support diversification of energy resources and enhance grid security;(5) reduce greenhouse gases and other air pollutants resulting from power generation;(6) provide the public utility with the discretion, subject to applicable laws and rules, to operate, maintain and control energy storage systems so as to ensure reliable and efficient service to customers; and(7) are the most cost effective among feasible alternatives. E. As used in this section: (1) "energy storage system" means methods and technologies used to store electricity; and(2) "mutual domestic water consumer association" means an association created and organized pursuant to the provisions of:(a) Laws 1947, Chapter 206; Laws 1949, Chapter 79; or Laws 1951, Chapter 52; or(b) the Sanitary Projects Act [Chapter 3, Article 29 NMSA 1978].Laws 1941, ch. 84, § 46; 1941 Comp., § 72-701; 1953 Comp., § 68-7-1; Laws 1965, ch. 289, § 10; 1967, ch. 96, § 1; 1990, ch. 95, § 1; 2000, ch. 51, § 1; 2005, ch. 340, § 1.Amended by 2019, c. 65,s. 25, eff. 6/14/2019.
