This Report is submitted in compliance with NRS 704.754. The Report compiles information on projects made known to the Commission through the Utility Environmental Protection Act ("UEPA") process and utility transmission plans filed with the Commission by regulated utilities over the last biennium. The Commission takes no position regarding whether the projects listed in the Report will be constructed. Please be advised that NRS 704.865(d) exempts from its requirements transmission projects involving utility facilities that will be wholly owned by cooperatives, nonprofit corporations, or associations on federal lands and are subject to the provisions of the National Environmental Policy Act of 1969, 42 U.S.C. 4321 §§ et seq. Consequently, the Commission has not been formally noticed of such projects, and they are not included with this Report. Finally, NRS 704.754 provides that the Commission submit all information about any transmission plan. The Commission respectfully submits that the transmission plans filed with the Commission discussed herein are voluminous, including detailed multi-volume engineering and environmental studies. Therefore, the Commission has not included all of the information submitted with transmission plans. However, this information is available within the respective dockets on the NORTHERN NEVADA OFFICE SOUTHERN NEVADA OFFICE 1150 East William Street 9075 West Diablo Drive, Suite 250 Carson City, Nevada 89701-3109 Las Vegas, Nevada 89148 (775)684-6101 • Fax (775) 684-6110 http://puc.nv.gov (702)486-7210 • Fax (702) 486-7206 Commission's website at www.puc.nv.gov.

The Public Utilities Commission of Nevada "Biennial Transmission Projects Report 2019-2020" (NRS 704.754) UEPA Application Projects Under the Utility Environmental Protection Act ("UEPA"), the Commission is able to assess the siting of utility facilities in Nevada, including electric transmission facilities. Nevada Revised Statute ("NRS") 704.860(2) (a) defines a transmission facility as a transmission line or substation in excess of 200 kilovolts ("kV"). This definition includes generation-tie ("gen-tie") lines that run from the generator to a utility's transmission grid. Gen-tie lines are not typically considered to be transmission facilities by the Federal Energy Regulatory Commission ("FERC"), which is responsible for the regulatory oversight of transmission facilities. From January 1, 2019, to December 31, 2020, the Commission has been made aware of the following UEPA projects related to new transmission projects. The Commission does not know which of the projects listed in the UEPA applications will be permitted and constructed.
