June 1, 2020 Ms. Trisha Osborne Assistant Commission Secretary Public Utilities Commission of Nevada 1150 East William Street Carson City, Nevada 89701-3109 RE: Nevada Power Company d/b/a NV Energy’s Application addressing its annual revenue

requirement for general rates charged to all classes of electric customers, in Docket No. 20-06___ Dear Ms. Osborne: Accompanying this letter is an application by Nevada Power Company d/b/a NV Energy (“Nevada Power” or “Company”) fulfilling its previously announced commitment to seek a revenue requirement decrease of $120 million, despite analysis that indicates the revenue requirement reduction should be $95.5 million. The Company makes this request as part of its multipart plan to assist Nevada in its economic recovery efforts. NRS § 704.110(3)(a) requires that by the first Monday in June every 36 months, Nevada Power must file an application requesting a review of its general rate. Nevada Power’s last general rate review application was filed in the spring of 2017. Accompanying this letter is Nevada Power’s 2020 Application Addressing Its Electric Utility Annual Revenue Requirement. This 2020 rate review application is mandated by statute and is filed in compliance therewith. Chapter 703 of the Nevada Administrative Code (“NAC”) sets forth the body of regulations implementing NRS § 704.110. Specifically, NAC § 703.2201 through NAC § 703.2481, inclusive, prescribe the manner in which general rate applications are to be prepared and filed. The entire filing is contained in twenty-five volumes, which are numbered sequentially and are individually indexed. Volumes sixteen through nineteen set forth responses to the Commission’s Master Data Request (“MDR”). Workpapers are provided in volumes twenty to twenty-five. These materials, along with all required application exhibits, statements, schedules and prepared direct testimony, are incorporated into and together constitute the Company’s prima facie direct case. A complete index of the entire filing by volume is attached to this transmittal letter. The Commission’s Regulatory Operations Staff (“Staff”), and the Attorney General’s Bureau of Consumer Protection (“BCP”) will be served today with electronic copies of the filing, along with the executable electronic copies and schedules and statements, as well as responses to all MDRs. In addition, Nevada Power is preparing hard copies for Staff’s Carson City office and the Las Vegas office. Similarly, the BCP will have hard copies for their Las Vegas office, and for their Carson City office. These will be delivered as they become available. Accompanying this transmittal letter are excerpts of the filing that are to be kept under seal pursuant to NAC § 703.527 et seq. This information is contained in a sealed envelope, appropriately marked, and contains the unredacted versions of the following:

Protective agreements with the Staff and BCP have already been executed and are in place. Staff and BCP will be served today with confidential unredacted versions of the above-described material. Please also note that NRS § 704.110(2) provides that the Commission must issue a written order approving or disapproving, in whole or in part, a general rate review application within 210 days of its filing or the application is deemed approved.
