and certain other matters about us and our financial condition. The second part, the base prospectus, provides general information about the first mortgage bonds and other securities that we may offer from time to time, some of which may not apply
to the bonds we are offering hereby. Generally, when we refer to the prospectus, we are referring to both parts of this document combined. If the description of the bonds varies between this prospectus supplement and the accompanying base
prospectus, you should rely on the information in this prospectus supplement. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">References in this prospectus to &#147;Southern California

for listing of the bonds on any securities exchange or for quotation on any automated dealer quotation system. The liquidity of any market for the bonds will depend on the number of holders of the bonds, the interest of securities dealers in making
a market in the bonds, and other factors. Accordingly, we cannot assure you as to the development or liquidity of any market for the bonds. If an active trading market does not develop, the market price and liquidity of the bonds may be adversely
affected. If the bonds are traded, they may trade at a discount from their initial offering price depending upon prevailing interest rates, the market for similar securities, general economic conditions, our performance and business prospects, and

the collateral securing the bonds. The trustees shall take any action if requested to do so by the holders of a majority in interest of the first mortgage bonds then outstanding under the first mortgage bond indenture and if indemnified to the
trustees&#146; reasonable satisfaction. Thus, you may not be able to exercise any control over the trustees&#146; exercise of remedies unless you can obtain the consent of holders of a majority of the total amount of first mortgage bonds

benefit of all holders of other series of our first mortgage bonds. The value of the pledged assets in the event of a liquidation will depend upon market and economic conditions, the availability of buyers, and similar factors. No independent
appraisals of any of the pledged property have been prepared by us or on our behalf in connection with this offering. Although our first mortgage bond indenture only allows us to issue first mortgage bonds with an aggregate principal amount at any

all amounts due on your bonds, you would have only an unsecured claim against our remaining assets. By their nature, some or all of the pledged assets might be illiquid and might have no readily ascertainable market value. Likewise, we cannot assure

mortgage bond indenture is likely to be significantly impaired by applicable bankruptcy law if a bankruptcy case were to be commenced by or against us before the indenture trustees repossessed and disposed of the pledged assets. Under Title 11 of
the United States Code (the &#147;Bankruptcy Code&#148;), a secured creditor is prohibited from repossessing its security from a debtor in a bankruptcy case, or from disposing of security repossessed from such debtor, without bankruptcy court
approval. Moreover, the Bankruptcy Code permits the debtor to continue to retain and to use collateral, including capital stock, even though the debtor is in default under the applicable debt instruments, provided that the secured creditor is given
&#147;adequate protection.&#148; In view of the lack of a precise definition of the term &#147;adequate protection&#148; and the broad discretionary powers of a bankruptcy court, it is impossible to predict (1)&nbsp;how long payments under the bonds
could be delayed following commencement of a bankruptcy case, (2)&nbsp;whether or when the indenture trustee could repossess or dispose of the pledged assets or (3)&nbsp;whether or to what extent holders of the bonds would be compensated for any
delay in payment or loss of value of the pledged assets through the requirement of &#147;adequate protection.&#148; </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>The ability of the indenture

(&#147;ARRC&#148;) convened by the Board of Governors of the Federal Reserve System and the Federal Reserve Bank of New York identified the SOFR as the rate that, in the consensus view of the ARRC, represented best practice for use in certain new
U.S. dollar derivatives and other financial contracts. SOFR is a broad measure of the cost of borrowing cash overnight collateralized by U.S. Treasury securities, and has been published by the Federal Reserve Bank of New York since April&nbsp;2018.
The Federal Reserve Bank of New York has also begun publishing historical indicative Secured Overnight Financing Rates from 2014. Investors should not rely on any historical changes or trends in SOFR as an indicator of future changes in SOFR. </P>

SOFR is an overnight rate, while LIBOR is a forward-looking rate that represents interbank funding over different maturities (e.g., three&nbsp;months). As a result, there can be no assurance that
SOFR (including Compounded SOFR) will perform in the same way as LIBOR would have at any time, including, without limitation, as a result of changes in interest and yield rates in the market, market volatility or global or regional economic,
financial, political, regulatory, judicial or other events. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>SOFR may be more volatile than other benchmark or market rates. </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Since the initial publication of SOFR, daily changes in SOFR have, on occasion, been more volatile than daily changes in other benchmark or
market rates, such as U.S. dollar LIBOR. Although changes in Compounded SOFR generally are not expected to be as volatile as changes in daily levels of SOFR, the return on and value of the Floating Rate Bonds may fluctuate more than floating rate
debt securities that are linked to less volatile rates. In addition, the volatility of SOFR has reflected the underlying volatility of the overnight U.S. Treasury repo market. The Federal Reserve Bank of New&nbsp;York has at times conducted
operations in the overnight U.S. Treasury repo market in order to help maintain the federal funds rate within a target range. There can be no assurance that the Federal Reserve Bank of New York will continue to conduct such operations in the future,
and the duration and extent of any such operations is inherently uncertain. The effect of any such operations, or of the cessation of such operations to the extent they are commenced, is uncertain and could be materially adverse to investors in the
Floating Rate Bonds. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Any failure of SOFR to gain market acceptance could adversely affect the Floating Rate Bonds. </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">According to the ARRC, SOFR was developed for use in certain U.S. dollar derivatives and other financial contracts as an alternative to U.S.
dollar LIBOR in part because it is considered a good representation of general funding conditions in the overnight U.S. Treasury repurchase agreement market. However, as a rate based on transactions secured by U.S. Treasury securities, it does not
measure bank-specific credit risk and, as a result, is less likely to correlate with the unsecured short-term funding costs of banks. This may mean that market participants would not consider SOFR a suitable replacement or successor for all of the
purposes for which U.S.&nbsp;dollar LIBOR historically has been used (including, without limitation, as a representation of the unsecured short-term funding costs of banks), which may, in turn, lessen market acceptance of SOFR. Any failure of SOFR
to gain market acceptance could adversely affect the return on and value of the Floating Rate Bonds and the price at which investors can sell the Floating Rate Bonds in the secondary market. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">In addition, if SOFR does not prove to be widely used as a benchmark in securities that are similar or comparable to the Floating Rate Bonds,
the trading price of the Floating Rate Bonds may be lower than those of securities that are linked to rates that are more widely used. Similarly, market terms for floating-rate debt securities linked to SOFR, such as the spread over the base rate
reflected in interest rate provisions or the manner of compounding the base rate, may evolve over time, and trading prices of the Floating Rate Bonds may be lower than those of later-issued SOFR-based debt securities as a result. Investors in the
Floating Rate Bonds may not be able to sell the Floating Rate Bonds at all or may not be able to sell the Floating Rate Bonds at prices that will provide them with a yield comparable to similar investments that have a developed secondary market, and
may consequently suffer from increased pricing volatility and market risk. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>The interest rate on the Floating Rate Bonds is based on a Compounded SOFR
rate and the SOFR Index, both of which are relatively new in the marketplace. </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">For each interest period (as defined below), the
interest rate on the Floating Rate Bonds is based on Compounded SOFR, which is calculated using the SOFR Index (as defined below) published by the Federal Reserve Bank of New York according to the specific formula described under &#147;Certain Terms
of the Bonds&#151;Interest and Maturity&#151;Floating Rate Bonds&#151;Compounded SOFR,&#148; not the SOFR rate published on or in respect of a particular date during such interest period or an arithmetic average of SOFR rates during such period. For
this and other reasons, the interest rate on the Floating Rate Bonds during any interest period will not necessarily be the same as the interest rate on other SOFR-linked investments that use an alternative basis to determine the applicable interest
rate. Further, if the SOFR rate in respect of a particular date during an interest </P>

use SOFR as the interest rate and the method for calculating an interest rate based upon SOFR in those precedents varies. In addition, the Federal Reserve Bank of New York only began publishing the SOFR Index on March&nbsp;2, 2020. Accordingly, the
use of the SOFR Index or the specific formula for the Compounded SOFR rate used in the Floating Rate Bonds may not be widely adopted by other market participants, if at all. If the market adopts a different calculation method, that would likely
adversely affect the liquidity and market value of the Floating Rate Bonds. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Compounded SOFR with respect to a particular interest period will only be
capable of being determined near the end of the relevant interest period. </B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">The level of Compounded SOFR applicable to a particular
interest period and, therefore, the amount of interest payable with respect to such interest period will be determined on the Interest Payment Determination Date (as defined below) for such interest period. Because each such date is near the end of
such interest period, you will not know the amount of interest payable with respect to a particular interest period until shortly prior to the related Floating Rate Interest Payment Date and it may be difficult for you to reliably estimate the
amount of interest that will be payable on each such Floating Rate Interest Payment Date. In addition, some investors may be unwilling or unable to trade the Floating Rate Bonds without changes to their information technology systems. An inability
to reliably estimate accrued and unpaid interest as well as potential need for some investors to change their information technology systems could both adversely impact the liquidity and trading price of the Floating Rate Bonds. </P>

relatively recent introduction, that the SOFR Index will not be discontinued or fundamentally altered in a manner that is materially adverse to the interests of investors in the Floating Rate Bonds. If the manner in which the SOFR Index is
calculated, including the manner in which SOFR is calculated, is changed, that change may result in a reduction in the amount of interest payable on the Floating Rate Bonds and the trading prices of the Floating Rate Bonds. In addition, the Federal
Reserve Bank of New York may withdraw, modify or amend the published SOFR Index or SOFR data in its sole discretion and without notice. The interest rate for any interest period will not be adjusted for any modifications or amendments to the SOFR

mortgage bonds outstanding (including $751.9&nbsp;million of first mortgage bonds issued to secure pollution control bonds). As of March&nbsp;31, 2021, we had the capacity to issue approximately $16.8&nbsp;billion of additional first mortgage bonds
on the basis of first mortgage bonds previously acquired, redeemed, or otherwise retired and the net amount of additional property acquired by us and not previously used for the issuance of first mortgage bonds or other purposes under the first
mortgage bond indenture. The first mortgage bond indenture&#146;s net earnings coverage test provides that additional first mortgage bonds may not be issued unless our net earnings (as defined in the first mortgage bond indenture) for a period of
twelve months ending no more than 60 days prior to the delivery of the bonds shall have been at least two <FONT STYLE="white-space:nowrap">and&nbsp;one-half&nbsp;(2.5x)</FONT> times our total annual first mortgage bond interest charge. Under the net
earnings test, the amount of additional first mortgage bonds we currently could issue is approximately $21.7&nbsp;billion (based on net earnings as of March&nbsp;31, 2021, and not taking into account the issuance of the bonds). See &#147;Description

part of UK domestic law by virtue of the European Union (Withdrawal) Act 2018 (&#147;EUWA&#148;); or (ii)&nbsp;a customer within the meaning of the provisions of the Financial Services and Markets Act 2000 (&#147;FSMA&#148;) and any rules or

the first mortgage bond indenture pursuant to clause (a)&nbsp;above. The net amount of additional property against which bonds might be issued under the first mortgage bond indenture pursuant to clause (c)&nbsp;above was approximately
$28.3&nbsp;billion, resulting in the ability to issue $18.9&nbsp;billion of Bonds pursuant to clause (c) (<I>i.e. </I>$28.3&nbsp;billion x .6666 = $18.9&nbsp;billion). The aggregate amount of bonds which we could issue under clauses (a)&nbsp;and (c)
above would, if other conditions were met, be approximately $18.9&nbsp;billion. As of June&nbsp;30, 2018, we had $12.4&nbsp;billion of our first mortgage bonds outstanding (including the first mortgage bonds issued to secure $751.9&nbsp;million of

<FONT STYLE="white-space:nowrap">one-half</FONT> (2.5x) times our total annual first mortgage bond interest charge. At June&nbsp;30, 2018, under the net earnings test we could issue $20.4&nbsp;billion of additional first mortgage bonds (based on net
earnings for the year ended June&nbsp;30, 2018). Notwithstanding the net earnings requirement, additional first mortgage bonds may be issued under the provisions referred to in (a)&nbsp;and (b) above under some circumstances involving, among other
things, issuance of bonds not bearing a higher interest rate than the bonds to be retired, issuance of bonds to pay or redeem bonds maturing within two years and issuance of bonds on the basis of acquisition, redemption or other retirement of

duty to resign is not inconsistent with the interests of the holders of the outstanding bonds. In certain cases, the first mortgage bond indenture and the Trust Indenture Act require an indenture trustee to share the benefit of payments received as

payment in full of the senior debt of Southern California Edison, to the extent and in the manner set forth in the applicable prospectus supplement for the securities. (See &#147;Subordination&#148; below.) </P>

mortgage bonds are issued under and secured by the first mortgage bond indenture, which creates a lien on substantially all the properties of Southern California Edison for the benefit of the holders of the first mortgage bonds. The debt securities
other than first mortgage bonds that we are offering by this prospectus are not secured by any assets or property of Southern California Edison. </P>
