(a) An electric utility may not directly or indirectly provide service to the public under a franchise or permit unless the utility first obtains from the commission a certificate that states that the public convenience and necessity requires or will require the installation, operation, or extension of the service.
(b) Except as otherwise provided by this chapter, a retail electric utility may not furnish or make available retail electric utility service to an area in which retail electric utility service is being lawfully furnished by another retail electric utility unless the utility first obtains a certificate that includes the area in which the consuming facility is located.

(c) Notwithstanding any other provision of this chapter, including Subsection (a), an electric cooperative is not required to obtain a certificate of public convenience and necessity for the construction, installation, operation, or extension of any generating facilities or necessary interconnection facilities.
(c-1) Notwithstanding any other provision of this title except § 11.009, and except as provided by Subsection (c-2), a person, including an electric utility or municipally owned utility, may not interconnect a facility to the ERCOT transmission grid that enables additional power to be imported into or exported out of the ERCOT power grid unless the person obtains a certificate from the commission stating that public convenience and necessity requires or will require the interconnection. The person must apply for the certificate not later than the 180th day before the date the person seeks any order from the Federal Energy Regulatory Commission related to the interconnection. The commission shall apply § 37.056 in considering an application under this subsection. In addition, the commission must determine that the application is consistent with the public interest before granting the certificate. The commission may adopt rules necessary to implement this subsection. This subsection does not apply to a facility that is in service on December 31, 2014.
(c-2) The commission, not later than the 185th day after the date the application is filed, shall approve an application filed under Subsection (c-1) for a facility that is to be constructed under an interconnection agreement appended to an offer of settlement approved in a final order of the Federal Energy Regulatory Commission that was issued in Docket No. TX11-01-001 on or before December 31, 2014, directing physical connection between the ERCOT and SERC regions under Sections 210, 211, and 212 of the Federal Power Act (16 U.S.C. Sections 824i, 824j, and 824k). In approving the application, the commission may prescribe reasonable conditions to protect the public interest that are consistent with the final order of the Federal Energy Regulatory Commission.
(c-3) Nothing in Subsection (c-1) or (c-2) is intended to restrict the authority of the commission or the independent organization certified under § 39.151 for the ERCOT power region to adopt rules or protocols of general applicability.

(g) A municipally owned utility or a municipal power agency created under Chapter 163 may not directly or indirectly construct, install, or extend a transmission facility outside of the municipal boundaries of the municipality that owns the municipally owned utility, or the power agency’s boundaries, which for the purposes of this subsection consist of the municipal boundaries of the participating public entities, unless the municipally owned utility or power agency first obtains from the commission, through the application process provided by § 37.053, a certificate that states that the public convenience and necessity requires or will require the transmission facility. § 37.056 applies to an application under this subsection.

(1) upgrades to an existing transmission line that do not require any additional land, right-of-way, easement, or other property not owned by the municipally owned utility; and
(2) the construction, installation, or extension of a transmission facility that is entirely located not more than 10 miles outside of a municipally owned utility’s certificated service area that occurs before September 1, 2021.
(i) The commission, not later than the 185th day after the date the application is filed, shall approve an application filed under Subsection (g) for a facility that is to be constructed under an interconnection agreement appended to an offer of settlement approved in a final order of the Federal Energy Regulatory Commission that was issued in Docket No. TX11-01-001 on or before December 31, 2014, directing physical connection between the ERCOT and SERC regions under Sections 210, 211, and 212 of the Federal Power Act (16 U.S.C. Sections 824i, 824j, and 824k). In approving the application, the commission may prescribe reasonable conditions to protect the public interest that are consistent with the final order of the Federal Energy Regulatory Commission.
