Item 8.01 Other Events.

On April 9, 2018, Nevada Power Company (the “Company”), a wholly-owned subsidiary of NV Energy, Inc., an indirect wholly-owned subsidiary of Berkshire Hathaway Energy Company, entered into an Underwriting Agreement between the Company and the underwriters named therein regarding the issuance and sale of $575 million of the Company’s 2.75% General and Refunding Mortgage Notes, Series BB, due 2020 (the “Notes”). The Underwriting Agreement contains certain customary representations, warranties and covenants concerning the Company and the registration statement relating to the offering of the Notes. In addition, the Company has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended, and the Securities Exchange Act of 1934, as amended. The Company expects the transaction to close on April 12, 2018, subject to the satisfaction of customary closing conditions, as further described in the Underwriting Agreement.

The Company will pay interest on the Notes April 15 and October 15 of each year, beginning on October 15, 2018. The Notes, which will be issued under and secured by the General and Refunding Mortgage Indenture, dated as of May 1, 2001, as amended and supplemented (the ‘‘G&R Indenture’’), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee, will mature on April 15, 2020. The Company intends to use the net proceeds from the sale of the Notes to repay the Company’s $325 million 6.50% General and Refunding Mortgage Notes, Series O, maturing in May 2018, to repay a portion of the Company’s $500 million 6.50% General and Refunding Mortgage Notes, Series S, maturing in August 2018, and for general corporate purposes.

At any time prior to April 15, 2020, the Company may redeem the Notes at its option, in whole at any time or in part from time to time, at a redemption price equal to the greater of (a) 100% of the principal amount of the Notes being redeemed and (b) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes being redeemed (excluding the portion of any such interest accrued to the date of redemption) discounted to the redemption date on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate (as defined in the Officer’s Certificate) plus 10 basis points, plus, in each case, accrued interest thereon to the date of redemption.

The foregoing discussion of the Notes is qualified in its entirety by reference to the Officer’s Certificate establishing the terms of the Notes under the G&R Indenture, a copy of which is attached hereto as Exhibit 4.1 and incorporated into this Item 8.01 by reference.
