                          SUPPLEMENTAL DESCRIPTION OF
                            THE 1994 SERIES A BONDS
 
     This Prospectus Supplement relates to the offer and sale of $140,000,000
principal amount of First and Refunding Mortgage 5 1/2% Bonds, 1994 Series A,
due February 1, 1999 (1994 Series A Bonds) of The Connecticut Light and Power
Company (the Company). The 1994 Series A Bonds are the second series of New
Bonds that are covered by the accompanying Prospectus (the Prospectus). The
section of the Prospectus entitled "Description of the New Bonds" contains
detailed information about the New Bonds. Below is set forth supplemental
information that more specifically relates to the 1994 Series A Bonds.
 
GENERAL
 
     The 1994 Series A Bonds will be issued under a Supplemental Indenture dated
as of February 1, 1994 and will bear interest from the date of original issuance
at the rate of 5 1/2% per annum. Interest will be payable semi-annually in
arrears on February 1 and August 1 of each year, commencing August 1, 1994, to
registered owners as of the close of business on the January 15 or July 15 next
preceding the interest payment dates, or if January 15 or July 15 falls on a day
on which banks are authorized to close in New York City, then as of the next
preceding banking day.
 
     The 1994 Series A Bonds will be issued initially under a book-entry only
system in the form of one fully registered certificate, registered in the name
of Cede & Co., as registered bondholder and nominee of The Depository Trust
Company, New York, New York (DTC).  DTC will act as securities depository for
the 1994 Series A Bonds. So long as Cede & Co., as nominee of DTC, or any
successor nominee of DTC, is the registered bondholder of the 1994 Series A
Bonds, references herein and in the Prospectus to the bondholders or registered
owners of 1994 Series A Bonds will mean Cede & Co. or such successor nominee.
See "Book-Entry Only System" herein for certain information regarding DTC and
the book-entry only system.
 
     For information concerning the requirements of the Indenture and for
additional general information about the Indenture and the New Bonds issuable
thereunder, see "Description of the New Bonds" in the Prospectus.
 
EARNINGS COVERAGE
 
     The section of the Prospectus entitled "Description of the New Bonds --
Issuance of Additional Bonds, Earnings Coverage" sets forth information about
earnings coverage requirements of the Indenture. Based on the bonds and prior
lien obligations outstanding as of December 31, 1993 and after giving effect to
the Company's redemption of $125,000,000 principal amount of bonds on January 7,
1994 and the sale of the 1994 Series A Bonds and $140,000,000 principal amount
of 1994 Series B Bonds due February 1, 2004 (1994 Series B Bonds) being sold
concurrently herewith, the earnings coverage would be 3.67 for the twelve months
ended December 31, 1993.
 
REDEMPTION PROVISIONS OF THE 1994 SERIES A BONDS
 
     The 1994 Series A Bonds will not be redeemable as a whole or in part at any
time.
 
     If the Company seeks to eliminate or modify the requirements of the annual
sinking and improvement fund, and subject to the receipt of any required
regulatory approvals, the holders of the New Bonds, including the 1994 Series A
Bonds, will be deemed to have consented to any such amendment or amendments of
the Indenture. See "Description of the New Bonds--Sinking and Improvement Fund"
in the Prospectus.
 
DIVIDEND RESTRICTIONS
 
     See "Description of the New Bonds--Dividend Restrictions" in the Prospectus
for information about dividend limitations binding on the Company so long as
certain prior series of bonds are outstanding. The most restrictive provisions
currently binding on the Company are set forth in the Supplemental Indenture
dated as of July 1, 1992, under which $100,000,000 principal amount of Series VV
Bonds due July 1, 1999 were issued. Under these provisions, which are applicable
so long as any Series VV Bonds are outstanding, unrestricted earned surplus at
December 31, 1993 would have been $210,623,483.
 
                                      S-3
 

OTHER FINANCIAL RESTRICTIONS
 
     For information on financial restrictions applicable to the Company, see
"Description of the New Bonds-- Other Financial Restrictions" in the Prospectus
and the Company's 1992 Annual Report on Form 10-K under the caption "Item 1.
Business--Financing Program--Financing Limitations." At December 31, 1993, the
Company's equity ratio (calculated in accordance with the DPUC decision
approving NU's acquisition of PSNH, which decision requires the inclusion or
short-term debt in excess of 7% of total capitalization) was 39.1%
 
USE OF PROCEEDS
 
     The net proceeds from the issue and sale of the 1994 Series A Bonds and the
1994 Series B Bonds, plus the proceeds of short-term debt, will be used to
redeem $310,000,000 principal amount of bonds previously issued by the Company
and HELCO. The bonds to be redeemed include 10 series of bonds with maturities
ranging from April 1, 1997 to May 1, 2003 and interest rates ranging from 5.625%
to 7.625%. The weighted average interest rate of all bonds to be redeemed is
7.11%.
 
                             BOOK-ENTRY ONLY SYSTEM
 
     The description which follows of the procedures and recordkeeping with
respect to beneficial ownership interests in the 1994 Series A Bonds, payments
of principal of, and premium, if any, and interest on, the 1994 Series A Bonds
to DTC and its Participants or Beneficial Owners, in each case as defined below,
confirmation and transfer of beneficial ownership interests in the 1994 Series A
Bonds and other related transactions by and among DTC, the DTC Participants and
Beneficial Owners is based solely on information furnished by DTC.
 
     DTC is a limited-purpose trust company organized under the New York Banking
Law, a "banking organization" within the meaning of the New York Banking Law, a
member of the Federal Reserve System, a "clearing corporation" within the
meaning of the New York Uniform Commercial Code, and a "clearing agency"
registered pursuant to the provisions of Section 17A of the Securities Exchange
Act of 1934. DTC holds securities that its participants (Participants) deposit
with DTC.  DTC also facilitates the settlement among Participants of securities
transactions, such as transfers and pledges, in deposited securities through
electronic computerized book-entry changes in Participants' accounts, thereby
eliminating the need for physical movement of securities certificates. Direct
Participants (Direct Participants) include securities brokers and dealers,
banks, trust companies, clearing corporations and certain other organizations.
DTC is owned by a number of its Direct Participants and by the New York Stock
Exchange, Inc., the American Stock Exchange, Inc. and the National Association
of Securities Dealers, Inc. Access to the DTC system is also available to others
such as securities brokers and dealers, banks and trust companies that clear
through or maintain a custodial relationship with a Direct Participant, either
directly or indirectly (Indirect Participants). The rules applicable to DTC and
its Participants are on file with the Securities and Exchange Commission.
 
     Purchases of 1994 Series A Bonds under the DTC system must be made by or
through Direct Participants, which will receive a credit for the 1994 Series A
Bonds on DTC's records. The ownership interest of each actual purchaser of 1994
Series A Bonds (Beneficial Owner) is in turn to be recorded on the Direct and
Indirect Participants' records. Beneficial Owners will not receive written
confirmation from DTC of their purchase, but Beneficial Owners are expected to
receive written confirmations providing details of the transaction, as well as
periodic statements of their holdings, from the Direct or Indirect Participant
through which the Beneficial Owner entered into the transaction. Transfers of
ownership interests in the 1994 Series A Bonds are to be accomplished by entries
made on the books of Participants acting on behalf of Beneficial Owners.
Beneficial Owners will not receive certificates representing their ownership
interests in the 1994 Series A Bonds, except in the event that use of the
book-entry system for the 1994 Series A Bonds is discontinued. SO LONG AS CEDE &
CO., AS NOMINEE FOR DTC, IS THE SOLE HOLDER OF THE 1994 SERIES A BONDS, THE
TRUSTEE SHALL TREAT CEDE & CO. AS THE ONLY HOLDER OF THE 1994 SERIES A BONDS FOR
ALL PURPOSES UNDER THE INDENTURE, INCLUDING RECEIPT OF ALL PRINCIPAL OF, AND
PREMIUM, IF ANY, AND INTEREST ON SUCH BONDS, RECEIPT OF NOTICES, AND VOTING AND
REQUESTING OR DIRECTING THE TRUSTEE TO TAKE OR NOT TO TAKE, OR CONSENTING TO,
CERTAIN ACTIONS UNDER THE INDENTURE.
 
     To facilitate subsequent transfers, all 1994 Series A Bonds deposited by
Participants with DTC are registered in the name of DTC's partnership nominee,
Cede & Co. The deposit of 1994 Series A Bonds with DTC and their registration in
the name of Cede & Co. effect no change in beneficial ownership. DTC has no
knowledge of the
                                      S-4
 

actual Beneficial Owners of the 1994 Series A Bonds; DTC's records reflect only
the identity of the Direct Participants to whose accounts such 1994 Series A
Bonds are credited, which may or may not be the Beneficial Owners. The
Participants will remain responsible for keeping account of their holdings on
behalf of their customers.
 
     Conveyance of notices and other communications by DTC to Direct
Participants, by Direct Participants to Indirect Participants, and by Direct
Participants and Indirect Participants to Beneficial Owners will be governed by
arrangements among them, subject to any statutory or regulatory requirements as
may be in effect from time to time.
 
     Redemption notices, if any, shall be sent to Cede & Co. If less than all of
the Securities within an issue are being redeemed, DTC's practice is to
determine by lot the amount of the interest of each Direct Participant in such
issue to be redeemed.
 
     Neither DTC nor Cede & Co. will consent or vote with respect to the 1994
Series A Bonds. Under its usual procedures, DTC mails an Omnibus Proxy to the
Company as soon as possible after the record date. The Omnibus Proxy assigns
Cede & Co.'s consenting or voting rights to those Direct Participants to whose
accounts the 1994 Series A Bonds are credited on the record date (identified in
a listing attached to the Omnibus Proxy).
 
     Principal of, and premium, if any, and interest payments on the 1994 Series
A Bonds will be made to DTC. DTC's practice is to credit Direct Participants'
accounts on the applicable payment date in accordance with their respective
holdings shown on DTC's records unless DTC has reason to believe that it will
not receive payment on such date. Payments by Participants to Beneficial Owners
will be governed by standing instructions and customary practices, as is the
case with securities held for the accounts of customers in bearer form or
registered in "street name," and will be the responsibility of such Participant
and not of DTC, the Trustee or the Company, subject to any statutory or
regulatory requirements as may be in effect from time to time. Payment of
principal, and premium, if any, and interest to DTC is the responsibility of the
Company or the Trustee, disbursement of such payments to Direct Participants
shall be the responsibility of DTC, and disbursement of such payments to the
Beneficial Owners shall be the responsibility of Direct and Indirect
Participants.
 
     DTC may discontinue providing its services as securities depository with
respect to the 1994 Series A Bonds at any time by giving reasonable notice to
the Company or the Trustee. Under such circumstances, in the event that a
successor securities depository is not obtained, individual bond certificates
are required to be printed and delivered.
 
     The Company may decide to discontinue use of the system of book-entry
transfers through DTC (or a successor securities depository). In that event,
individual bond certificates will be printed and delivered.
 
     The information in this section concerning DTC and DTC's book-entry system
has been obtained from sources that the Company believes to be reliable
(including DTC), but the Company takes no responsibility for the accuracy

                                  UNDERWRITING
 
     Subject to the terms and conditions set forth in the Underwriting
Agreement, the Company has agreed to sell to Goldman, Sachs & Co. (Goldman
Sachs), and Goldman Sachs have agreed to purchase, the entire principal amount
of the 1994 Series A Bonds.
 
     Under the terms and conditions of the Underwriting Agreement, Goldman Sachs
are committed to take and pay for all the 1994 Series A Bonds, if any are taken.
 
     Goldman Sachs propose to offer the 1994 Series A Bonds in part directly to
retail purchasers at the public offering price set forth on the cover page of
this Prospectus Supplement and in part to certain securities dealers at such
price less a concession of .200% of the principal amount of the 1994 Series A
Bonds. Goldman Sachs may allow, and such dealers may reallow, a concession not
in excess of .125% of the principal amount of the 1994 Series A Bonds to certain
brokers and dealers. After the 1994 Series A Bonds are released for sale to the
public, the offering price and other selling terms may from time to time be
varied by Goldman Sachs.
 
     The 1994 Series A Bonds are a new issue of securities with no established
trading market. The Company has been advised by Goldman Sachs that they intend
to make a market in the 1994 Series A Bonds but are not obligated to do so and
may discontinue market making at any time without notice. No assurance can be
given as to the liquidity of the trading market for the 1994 Series A Bonds.
 
     The Company has agreed to indemnify Goldman Sachs against certain
liabilities, including liabilities under the Securities Act of 1933.

                                  THE COMPANY
 
     The Company is a wholly-owned subsidiary of Northeast Utilities (NU). The
four wholly-owned operating subsidiaries of NU -- the Company, Public Service
Company of New Hampshire, Western Massachusetts Electric Company and Holyoke
Water Power Company -- furnish electric service in portions of Connecticut and
New Hampshire and in western Massachusetts. The Company is a Connecticut
corporation, organized in 1907, and is qualified as a foreign corporation in
Massachusetts and New Hampshire. The Company is the largest electric utility in
Connecticut and is engaged principally in the production, purchase,
transmission, distribution and sale of electricity at retail for residential,
commercial, industrial and municipal purposes within Connecticut.
 
     The principal executive offices of the Company are located at Selden
Street, Berlin, Connecticut 06037 (telephone 203-665-5000).
 
                                USE OF PROCEEDS
 
     The net proceeds from the issue and sale of the New Securities will be used
to refund, either through redemptions or open market purchases, outstanding
first mortgage bonds bearing relatively high interest rates and preferred stock
bearing relatively high dividend rates (collectively, the High Cost Securities)
or to refinance maturing debt and/or to fund sinking funds. The Company will
calculate a breakeven rate for each series of High Cost Securities, which is a
discount rate that equates the present value of the cash flow associated with
the new series of bonds (inclusive of call premiums and new issue expenses) to
the present value of the cash flow associated with the issue being redeemed
(assuming comparable maturities or average lives). The Company will not enter
into a proposed refunding transaction unless the breakeven rate for a series of
bonds or preferred stock to be refunded exceeds the then current market rate for
New Bonds or New Preferred Stock of similar amount and maturity or average life.
 
     The outstanding series of the Company's securities that may, depending on
prevailing interest rates, be considered High Cost Securities and therefore
candidates for redemption or purchase with the net proceeds from the issue and
sale of the New Bonds include First Mortgage Bonds with interest rates ranging
from 4.50% to 9.75% and maturities ranging from April 1, 1997 to September 1,
2019 and series of Preferred Stock with dividend rates ranging from 3.80% to
9.00% and average lives ranging from 11 years to perpetual. Since a series of
High Cost Securities may be refunded prior to the issuance of a series of New
Securities, short-term debt may be temporarily used to finance the refunding or
redemption and the proceeds from the issue and sale of the New Securities would
be used to repay this short-term debt.
 
     If a series of the New Securities is sold in advance of the maturity date
of the Company's short-term borrowings or the refunding of High Cost Securities,
the Company may temporarily invest the net proceeds from the sale of the New
Securities in the NU system money pool. The NU system money pool was established
by certain subsidiaries of NU, including the Company, to provide a more
efficient use of the cash resources of the system and to reduce outside
short-term borrowings. Short-term borrowing needs of member companies are first
met with available funds of other member companies and funds may be withdrawn or
repaid to the pool at any time without prior notice. Investing and borrowing
subsidiaries receive or pay interest based on the average daily Federal Fund
rate, except that borrowings based on loans from NU bear interest at NU's cost.
 
                          DESCRIPTION OF THE NEW BONDS
THE INDENTURE AND THE TRUSTEE
 
     Each Series of the New Bonds is to be issued under and secured by the
Indenture of Mortgage and Deed of Trust dated as of May 1, 1921 between the
Company and Bankers Trust Company, Trustee, as heretofore supplemented and
amended and which, as it is to be further supplemented by one or more
Supplemental Indentures, each of which would relate to a series of the New Bonds
(each of which is hereinafter referred to as a New Supplemental Indenture), is
hereinafter called the Indenture. The summary description of the provisions of
the Indenture which follows does not purport to be complete or to cover all the
provisions thereof; however, all material terms of the New Bonds are described
herein or, with respect to the specific terms of each series of New Bonds, will
be described more fully in the prospectus supplement relating to such series.
                                       3
 

Copies of the Indenture (exclusive of the New Supplemental Indentures) and a
form of New Supplemental Indenture have been filed as exhibits to, or
incorporated by reference in, the registration statement of which this
Prospectus is a part (the Registration Statement) and reference is made thereto
for a complete statement of the applicable provisions. Article and section
references herein are to provisions of the original Indenture as heretofore
amended unless otherwise indicated.
 
     The Trustee acts as a depository bank of, makes loans to, and performs
other services for the Company and other companies in the NU system in the
ordinary course of business.
 
GENERAL TERMS OF BONDS
 
     Each series of New Bonds will mature on the date provided for such series
and will bear interest from the date of original issuance at the rate per annum
shown in the series title. Interest will be payable semiannually at the
principal office of the Trustee in New York City, to registered owners at the
close of business on the record date set for each series, or if such record date
is a day on which banks are authorized to close in New York City, on the next
preceding banking day. The Prospectus Supplement with respect to each series of
New Bonds will set forth the maturity date, interest rate, interest payment
dates and record dates for such series.
 
     The New Bonds are to be issued only in the form of fully registered bonds
without coupons in denominations of $1,000 or multiples thereof and may be
presented for exchange for a like aggregate principal amount of the same series
of New Bonds of other authorized denominations and for transfer at the principal
office of the Trustee in New York City without payment in either case of any
charge other than for any tax or other governmental charges required to be paid
by the Company.
 
SECURITY
 
     Except as to The Hartford Electric Light Company (HELCO) property referred
to below, the Indenture constitutes a first mortgage lien (subject to liens
permitted by the Indenture, including liens and encumbrances existing at the
time of acquisition by the Company) on substantially all of the Company's
physical property and franchises, including the Company's generating stations
(but not including the Company's interest in the plants of the four regional
nuclear generating companies described under "Item 1. Business -- Electric
Operations -- Nuclear Generation -- General" of the Company's Annual Report on
Form 10-K for 1992) and its transmission and distribution facilities. Subject to
the provisions of the Federal Bankruptcy Code, the Indenture will also
constitute a lien on after-acquired property, although in Massachusetts it may
be necessary to comply with applicable recording requirements to perfect the
lien on after-acquired real property. The Indenture permits after-acquired
property to be subject to liens prior to that of the Indenture, and as a result
of the merger of HELCO into the Company as of the close of business on June 30,
1982, the lien of HELCO's first mortgage indenture remains a first lien on all
former HELCO property and additions to such property, with the Indenture
constituting a second lien on such HELCO properties. The security afforded by
the Indenture is for the equal and ratable protection of all the Company's
presently outstanding bonds and any bonds which may hereafter be issued under
the Indenture, including each series of New Bonds. (The granting clauses and
SectionSection6.04 and 6.05.)
 
     Under certain limited circumstances, the lien of the Indenture on real
property in Connecticut acquired by the Company after June 3, 1985 could be
subordinated to a lien in favor of the State of Connecticut pursuant to a
Connecticut law (Connecticut General Statutes Section 22a-452a) providing for
such a lien for reimbursement for expenses incurred in containing, removing or
mitigating hazardous waste.
 
     Also, under certain limited circumstances the lien of the Indenture on real
property in Massachusetts could be subordinated to a lien in favor of the
Commonwealth of Massachusetts pursuant to the Massachusetts Oil and Hazardous
Materials Release Prevention and Response Act, commonly known as the
Massachusetts Superfund.
 
     Further, under certain limited circumstances, the lien of the Indenture on
real property in New Hampshire, personal property located thereon and business
revenues generated therefrom could be subordinated to a lien in favor of the
State of New Hampshire pursuant to New Hampshire Revised Statutes Annotated
                                       4
 

147B:10-b, as amended, for expenses incurred in containing or removing hazardous
waste or materials, and any necessary mitigation of damages with respect to
hazardous waste or materials.
 
REDEMPTION PROVISIONS
 
     Unless otherwise provided in the Supplemental Indenture under which a
series of the New Bonds is issued, each series of the New Bonds will be
redeemable at the option of the Company as a whole or in part at any time upon
at least 30 days' prior written notice at redemption prices (expressed in
percentages of principal amount) that will be set forth in the New Supplemental
Indenture and the Prospectus Supplement with respect to such series, together in
each case with accrued and unpaid interest to the redemption date; provided,
however, that no New Bond of any series may be redeemed at the applicable
General Redemption Price prior to a date, approximately five years from the date
of issuance of such series and to be set forth in the Prospectus Supplement with
respect to such series, if such redemption is for the purpose of or in
anticipation of refunding such New Bond through the use, directly or indirectly,
of funds borrowed by the Company having an effective interest cost to the
Company (computed in accordance with generally accepted financial principles) of
less than the effective interest cost of New Bonds of such series. If the bonds
of any series of the New Bonds have a maturity of five or fewer years, they
would not be refundable with lower cost funds throughout the life of the bonds.
Unless otherwise provided in the Supplemental Indenture under which a series of
the New Bonds is issued, this refunding limitation will not be applicable to
redemptions of New Bonds at a Special Redemption Price. The Special Redemption
Prices will be applicable to redemptions at the option of the Company through
the use of sinking and improvement fund or replacement fund moneys or other
trust moneys representing insurance proceeds or the proceeds of the sale,
condemnation or other disposition of property. The Supplemental Indenture under
which a series of the New Bonds is issued may prohibit redemption before
maturity, in which case sinking and improvement fund moneys may not be applied
to the redemption of such New Bonds. Otherwise, for each of the first five
consecutive twelve-month periods, if the bonds of a series of New Bonds have a
maturity of more than five years, or for every twelve-month period, if the bonds
of a series of the New Bonds have a maturity of five or fewer years, redemption
of the New Bonds of such series with sinking and improvement fund moneys at the
Special Redemption Price will be limited to one percent (1%) of the aggregate
principal amount of the New Bonds of such series, commencing with the first day
of the month in which a series of New Bonds is issued. The General Redemption
Prices will be applicable to all other redemptions.
 
ISSUANCE OF ADDITIONAL BONDS; EARNINGS COVERAGE
 
     The Indenture permits, subject to various conditions and restrictions set
forth therein, the issuance of an unlimited amount of additional first mortgage
bonds. Additional bonds may be issued under the Indenture (a) to refund other
bonds or certain prior lien obligations, or (b) on the basis of a certification
of unbonded property additions, or (c) against the deposit of an equal amount of
cash with the Trustee. The aggregate amount of First Mortgage Bonds outstanding
on September 30, 1993 was $1,407,000,000.
 
     Additional bonds may be issued to the extent of 60% (or such greater
percent, not exceeding 66 2/3%, as may be authorized by the SEC under the Public
Utility Holding Company Act of 1935 (the Holding Company Act)) of unbonded
property additions (Section3.54). Additional bonds may also be issued to finance
60% (or such greater percent, not exceeding 66 2/3%, as may be authorized by the
SEC under the Holding Company Act) of the bondable amount of the Company's
interest in the inventory of nuclear fuel required for a nuclear generating
plant (Section3.55).
 
     Except in the case of certain refunding issues, the Company may not issue
additional bonds unless its net earnings, as defined and as computed without
deducting income taxes, for 12 consecutive calendar months during the period of
15 consecutive calendar months immediately preceding the first day of the month
in which the application to the Trustee for authentication of additional bonds
is made were at least twice the annual interest charges on all the Company's
outstanding bonds, including the proposed additional bonds, and any outstanding
prior lien obligations (Section3.58).
 
     On the basis of this formula, based on the bonds and prior lien obligations
outstanding as of September 30, 1993, the earnings coverage was 4.20. Giving
effect to the issuance of $325 million principal amount of
                                       5
 

New Bonds at an assumed rate of 7.25%, $125 million principal amount of New
Bonds at an assumed rate of 6.00% and $70 million principal amount of New Bonds
at an assumed rate of 4.625%, and assuming that $520 million of the proceeds are
used to refund High Coupon Bonds having a breakeven rate of 5.08% or above, the
earnings coverage for the twelve months ending September 30, 1993 would be 4.51.
 
     Where cash is deposited with the Trustee as a basis for the issue of bonds,
it may be withdrawn against 60% (or such greater percent, not exceeding 66 2/3%,
as may be authorized by the SEC under the Holding Company Act) of bondable
property additions or against the deposit of bonds or prior lien obligations
that would otherwise be available to be made the basis of the issue of
additional bonds. Such cash may also be used to purchase or redeem bonds of any
series as the Company may designate (Section3.56).
 
     As of September 30, 1993, the Company had unbonded property additions
available that would support the issuance of additional bonds in the principal
amount of $535,467,707.
 
OTHER FINANCIAL RESTRICTIONS
 
     In addition to the foregoing restrictions, there are additional limitations
upon the creation and/or issuance by the Company of long-term debt securities.
Under certain bank and bank reimbursement agreements, lenders are not required
to make additional loans or the maturity of indebtedness can be accelerated if
the Company does not meet an equity ratio that requires, in effect, that the
Company's common equity (as defined) be at least 27 percent of its total
capitalization.
 
     Other than the security afforded by the lien of the Indenture, and the
requirements with respect to minimum equity ratios described above, there are no
provisions of the Indenture that afford holders of the New Bonds protection in
the event of a highly leveraged transaction involving the Company. However, such
a transaction could require approval by the SEC under the Holding Company Act
and by other regulatory authorities. Given the SEC's mandate under the Holding
Company Act to protect utility company investors, management of the Company
believes that approval by the SEC would be unlikely in a highly leveraged
context.
 
     On March 31, 1992, the Connecticut Department of Public Utility Control
(DPUC) issued a decision approving NU's acquisition of Public Service Company of
New Hampshire (PSNH), which occurred on June 5, 1992. The DPUC's approval
included several conditions designed principally to insulate the Company's
customers from possible financial risks associated with NU's investment in PSNH.
Among the conditions is a requirement that the Company use its best efforts to
maintain the amount of common equity in the Company's capital structure
(including short-term debt in excess of 7 percent of total capitalization) above
36 percent. The Company must notify the DPUC if the ratio is projected to fall
below 36 percent, in which case the DPUC may conduct a review of the Company's
financial condition. At September 30, 1993, the Company's equity ratio (so
calculated) was 37.0%. Also, in future rate cases, the Company will be required
to accept a methodology for determining the Company's cost of capital for
ratemaking purposes without regard to NU's cost of capital if the DPUC finds
that the Company's actual debt costs are unduly influenced by effects of the
PSNH acquisition. These conditions are to remain in effect until the later of
May 15, 1998 and the time at which PSNH achieves investment grade ratings for
its first mortgage bonds and a common equity to total capitalization ratio of at
least 30 percent.
 
SINKING AND IMPROVEMENT FUND
 
     The Indenture specifies an annual sinking and improvement fund requirement
equal to 1% of the aggregate principal amount of the bonds of all series
outstanding at the applicable time of computation, except that bonds which have
been retired out of the proceeds of money deposited with the Trustee on a
release of property or which have been retired in other similar ways need not be
taken into account (Section6.14).
 
     The annual requirement must be met on or before May 1 in each year, and may
be satisfied by any of the following: (i) deposit of cash with the Trustee, (ii)
a certification of unbonded property additions taken at 60% (or such greater
percent, not exceeding 66 2/3%, as may be authorized by the SEC under the
Holding Company Act) of the amount certified, or (iii) a deposit of bonds or
prior lien obligations that would otherwise be available to be made the basis of
the issue of additional bonds. Cash so deposited may be withdrawn or applied
                                       6
 

to the purchase or redemption (at the applicable Special Redemption Price) of
bonds of any series designated by the Company or otherwise applied, as more
fully stated below under "Withdrawal or Application of Cash" (Section6.14).
 
RENEWAL AND REPLACEMENT FUND
 
     If, as at the end of any year, the aggregate amount expended by the Company
for property additions since December 31, 1966 is less than the "replacement
fund requirement" (referred to below) for the same period, the Company is
required to make up the deficit by depositing cash with the Trustee, or by
depositing with the Trustee bonds or prior lien obligations which would
otherwise be available as a basis for the issue of additional bonds or by
certifying unbonded property additions taken at 100% of the amount certified. At
the request of the Company, any cash so deposited may be used to purchase or
redeem (at the applicable Special Redemption Price) bonds of such series as the
Company may designate. A replacement fund deficit may thereafter be offset by
expenditures in a later year in excess of the requirement for such year and
thereupon the Company will be entitled, to the extent of such offset, to the
return of cash, bonds or prior lien obligations deposited to make up the deficit
or to reinstate as bondable any property additions certified for such purpose
(Section6.06).
 
     The replacement fund requirement is computed on an annual basis, and is
equal, for each year, to 2.25% of the average of the amounts carried on the
Company's books for depreciable property at the beginning and end of the year
(Section1.01(pp)). As of December 31, 1992, the Company's expenditures for
property additions had exceeded the replacement fund requirement by
$4,282,827,734.
 
WITHDRAWAL OR APPLICATION OF CASH
 
     Cash deposited with the Trustee pursuant to the sinking and improvement
fund or replacement fund requirements may, at the Company's option, be withdrawn
against a certification of unbonded property additions, or against the deposit
of bonds or prior lien obligations which would otherwise be available to be made
the basis of the issue of additional bonds or may be applied to the purchase or
redemption (at the applicable Special Redemption Price) of bonds of such series
as the Company may designate (SectionSection6.06, 6.14 and 9.04). Where cash to
be withdrawn against a certification of unbonded property additions has been
deposited pursuant to the sinking and improvement fund requirement, a withdrawal
is permitted equal to 60% (or such greater percent, not exceeding 66 2/3%, as
may be authorized by the SEC under the Holding Company Act) of the amount
certified (Section6.14). When the cash to be withdrawn has been deposited under
the replacement fund requirement, a withdrawal equal to 100% is permitted
(Section6.06).
 
     Restrictions on the redemption of New Bonds at the applicable Special
Redemption Price with moneys deposited with the Trustee pursuant to the annual
sinking and improvement fund are set forth in "Redemption Provisions."
 
DIVIDEND RESTRICTIONS
 
     The Indenture contains restrictions on the payment of common stock
dividends, which were included in Supplemental Indentures at the time of
issuance of prior series of bonds. If a dividend restriction is included for any
series of the New Bonds, the specific terms will be described in the Prospectus
Supplement for that series. The Supplemental Indenture dated as of July 1, 1992,
which contains restrictions applicable so long as any Series VV Bonds, maturing
July 1, 1999, are outstanding, currently contains the most restrictive
provision. Under this provision, the aggregate amount which may be declared,
paid or otherwise applied by the Company after the date of issuance of a series
of the New Bonds as dividends or other distributions on its common stock (other
than by way of stock dividends or when an equal amount of cash is received
concurrently as a capital contribution or on the sale of common stock) or to the
purchase or other acquisition of common stock may not exceed earned surplus (as
defined, and after deducting accrued preferred stock dividends) accumulated
after June 30, 1992, plus $207,000,000, plus such further amount as may be
authorized by the SEC under the Holding Company Act. Pursuant to these
provisions, unrestricted earned surplus at December 31, 1992 would have amounted
to approximately $208,721,000.
 
                                       7
 

     Similar dividend restrictions are binding on the Company so long as certain
prior series of the Company's bonds, and certain prior series of HELCO's bonds
that were assumed in connection with the merger of HELCO into the Company (see
"Security"), are outstanding.
 
DEFAULT
 
     The Indenture provides that the following events will constitute "events of
default" thereunder: failure to pay principal; failure for 90 days to pay
interest; failure to perform any of the other Indenture covenants for 90 days
after notice to the Company; failure to perform any covenant contained in any
lien securing prior lien obligations if such default permits enforcement of the
lien; and certain events in bankruptcy, insolvency or receivership
(Section10.02). The Indenture requires the Company to deliver to the Trustee an
annual officers' certificate as to compliance with certain provisions of the
Indenture (Section6.16).
 
     The Indenture provides that, if any event of default exists, the holders of
a majority in principal amount of the bonds outstanding may, after tender to the
Trustee of indemnity satisfactory to it, direct the sale of the mortgaged
property (Section10.04).
 
MODIFICATION OF THE INDENTURE
 
     The Indenture may be supplemented or amended to convey additional property,
to state indebtedness of companies merged, to add further limitations to the
Indenture, to evidence a successor company, or to make such provision in regard
to questions arising under the Indenture as may be necessary or desirable and
not inconsistent with its terms (Section14.01).
 
     The Indenture also permits the modification, with the consent of holders of
66 2/3% of the bonds affected, of any provision of the Indenture, except that
(a) no such modification may effect a reduction of such percentage or the
creation of a lien prior to or concurrent with that of the Indenture unless all
bondholders consent, (b) no bondholder who refuses to consent may be deprived of
his security and (c) the Company's obligations as to the maturities, payment of
principal, interest or premium and other terms of payment may not be modified
unless all affected bondholders consent (Section14.03).
 
                     DESCRIPTION OF THE NEW PREFERRED STOCK
GENERAL
 
     The Company's capital stock consists of shares of Common Stock, $25 par
value per share, as well as two classes of preferred stock, one designated
"Preferred Stock," having a par value of $50 per share, and the other designated
"Class A Preferred Stock," having a par value of $25 per share. The Preferred
Stock and the Class A Preferred Stock are hereinafter sometimes collectively
referred to as the Senior Stock.
 
     Shares of the Preferred Stock and shares of Class A Preferred Stock rank on
a parity in respect of dividends or payment in case of liquidation, and, to the
extent not fixed and determined by the Company's certificate of incorporation,
have the same rights, preferences and powers. Voting rights are the only
differences in rights between the two classes and are summarized below under
"Voting Rights."
 
     The Preferred Stock and the Class A Preferred Stock may be issued from time
to time in series when authorized by the Company's Board of Directors, up to the
number of authorized but unissued shares of Preferred Stock and Class A
Preferred Stock, respectively, set forth in the Company's certificate of
incorporation, as amended from time to time. The series designation, dividend
rate (or method of determining dividend rate), redemption prices and other terms
of each series are determined by the Board of Directors to the extent not fixed
by the Company's certificate of incorporation.
 
     The general provisions of the Senior Stock, applicable to all series of
Preferred Stock and Class A Preferred Stock, and the specific provisions
applicable to each series, including the New Preferred Stock, are set forth in
the certificate of incorporation. Copies of the applicable provisions of the
certificate of incorporation entitled Amended and Restated Provisions of
Statutory Certificate of Incorporation with Respect to Capital Stock of The
Connecticut Light and Power Company, and forms of the proposed amendments to the
certificate of incorporation establishing series of the New Preferred Stock, are
filed with or incorporated by
                                       8
 

reference in the registration statement of which this Prospectus is a part (the
Registration Statement), as exhibits.
 
     The provisions of the Company's Senior Stock are summarized below, and the
article references are to the provisions of Part II of the certificate of
incorporation. The summary does not purport to be complete or to cover all the
provisions thereof; however, all material terms of the New Preferred Stock are
described herein or, with respect to specific terms of each series of New
Preferred Stock, will be described more fully in the prospectus supplement
relating to such series. Reference is made to the aforementioned exhibits to the
Registration Statement for a complete statement of the Senior Stock provisions.
 
     The New Preferred Stock will be transferable at the offices of Northeast
Utilities Service Company (NUSCO), Berlin, Connecticut, Transfer Agent and
Registrar for the Senior Stock. Both the Company and NUSCO are wholly-owned
subsidiaries of Northeast Utilities.
 
EARNINGS COVERAGE -- SENIOR STOCK PROVISION
 
     The Senior Stock Provisions of the Company's certificate of incorporation
require for the issuance of additional Senior Stock that Income Before Interest
Charges (as defined) be at least one and one-half times the pro forma annual
interest charges on all indebtedness and annual dividend requirements on the
Senior Stock to be outstanding after the issuance of the additional stock (see
"Voting Rights"). On the basis of the Income Before Interest Charges and the
indebtedness and the Senior Stock outstanding as of September 30, 1993, this
ratio was 1.82. Giving effect to the sale, on October 20, 1993, of $80 million
of 5.30% Preferred Stock, 1993 Series (1993 Series), the planned issuance of
approximately $36 million in short-term debt in conjunction with the 1993 Series
issuance and the planned redemption, on November 5, 1993, of $110 million of
preferred stock previously issued by the Company and HELCO, the September 30,
1993 ratio would be 1.87 (adjusted historical coverage ratio). Giving effect to
the issuance of $110 million of the New Preferred Stock at an assumed rate of
4.79% and application of the proceeds to the redemption of all the High Dividend
Stock that had a breakeven rate of 4.79% or higher ($110 million aggregate par
value), the adjusted historical coverage ratio would be 1.91.
 
DIVIDEND RIGHTS
 
     Holders of Senior Stock of each class and series are entitled to receive
cumulative dividends when declared by the Board of Directors at the rate
provided for such class and series. Dividends may not be declared or paid on a
particular class and series of the Senior Stock unless dividends have been or
are contemporaneously declared or paid on the Senior Stock of all other classes
and series for all dividend periods terminating on the same or an earlier date.
No dividend may be paid on the Common Stock or other stock of the Company
subordinate to the Senior Stock in respect of dividends or assets (which
together with Common Stock is defined as "junior stock") unless full cumulative
dividends to the last preceding dividend date have been paid or set apart for
payment of the Senior Stock (Article II, SectionSection1, 2 and 3).
 
     The Company is, in effect, prohibited from making payments on junior stock,
by way of dividends or otherwise (other than in shares of junior stock), in an
amount which, if the percentage of junior stock equity (as defined) to total
capitalization (as defined) is less than 20%, would, together with all other
junior stock payments made within the preceding 12 months, exceed 50% of net
income available for dividends on junior stock, or, if such percentage is
between 20% and 25%, would, together with all other junior stock payments made
within the preceding 12 months, exceed 75% of such net income (Article II,
SectionSection4, 5 and 6).
 
     Dividends on each series of New Preferred Stock will be payable quarterly
or otherwise at the rate provided for such series.
 
SINKING FUND PROVISIONS
 
     If a sinking fund is provided for a particular series of New Preferred
Stock, the Prospectus Supplement will describe the terms of the sinking fund for
that series. See "Redemption and Purchase" below for limitations on the
Company's right to redeem or purchase Senior Stock if the Company is in arrears
in the payment of dividends on any outstanding shares of Senior Stock.
 
                                       9
 

REDEMPTION AND PURCHASE
 
     All or any part of any series of Senior Stock outstanding may be redeemed,
subject to certain limitations, at any time at the redemption price established
for such series, except that no redemption of less than all shares of Senior
Stock outstanding may be made if the Company is in arrears with respect to
payment of dividends on any shares of Senior Stock outstanding (Article III,
SectionSection1 through 3).
 
     The Company may purchase any outstanding shares of Senior Stock upon the
best terms reasonably obtainable, but not exceeding the then current redemption
price of such shares, except that no such purchase may be made if the Company is
in arrears with respect to payment of dividends on any shares of Senior Stock
outstanding or if any event of default exists under the Senior Stock provisions
(Article III, Section6).
 
     Unless otherwise provided in the Prospectus Supplement, each series of the
New Preferred Stock will be redeemable for other than sinking fund purposes as a
whole or in part at any time, at the option of the Company, upon at least 30
days' prior written notice on the terms described in the Prospectus Supplement
for that series.
 
     See the Prospectus Supplement with respect to any particular series of New
Preferred Stock for more information concerning the redemption provisions for
that series.
 
LIQUIDATION RIGHTS
 
     The Senior Stock is entitled to receive upon voluntary liquidation the then
current redemption price for the particular series and, upon involuntary
liquidation, $50 per share in the case of the Preferred Stock and $25 per share
in the case of the Class A Preferred Stock, plus in each case all dividends
accrued and unpaid to the date of such payment, before any payment is made on
junior stock (Article IV).
 
VOTING RIGHTS
 
     Except as otherwise provided by law or, as described below, by the Senior
Stock provisions, holders of Senior Stock have no voting rights.
 
     Whenever the holders of the Senior Stock have the right to vote or consent
to an action as provided by law or by the Senior Stock provisions, both classes
of Senior Stock (except as described below) vote together as a single class,
with each outstanding share of Senior Stock entitled to vote enjoying voting
rights proportionate to the ratio of (i) the par value represented by such share
to (ii) the par value represented by all shares of Senior Stock then
outstanding. In accordance with such formula, each share of Preferred Stock ($50
par value) will be entitled to a weighted vote equal to twice the vote of each
share of Class A Preferred Stock ($25 par value). Whenever only one class of the
Senior Stock shall have the right to vote or consent to an action as provided by
law or, as described below, by the Senior Stock provisions, or whenever each
class of the Senior Stock shall be entitled or be required to vote as a separate
class on a matter, each outstanding share of such class entitled to vote shall
be entitled to one vote on each such matter (Article V, Section2).
 
     Whenever dividends on any share of Senior Stock are in arrears in an amount
equal to or exceeding full dividend payments for one year or whenever there
exists a default in the performance of any of the Senior Stock provisions or a
default on which action has been taken by bondholders or the trustee of any
mortgage of the Company, or whenever the Company has been declared bankrupt or a
receiver of its property has been appointed, the holders of both classes of
Senior Stock have the right, voting together as a single class, to elect the
smallest number of directors necessary to constitute a majority of the Board of
Directors. Such voting rights shall cease upon the termination of the condition
giving rise thereto (Article V, Section3).
 
     Without the consent of the holders of a majority of the aggregate voting
rights represented by shares of the Senior Stock then outstanding, or in the
event of dissent by or negative vote of holders of one-third of the aggregate
voting rights represented by shares of the Senior Stock then outstanding, the
Company may not (Article VI, Section4):
 
     1. Issue or assume unsecured notes, unsecured debentures or other
     securities representing unsecured debt (except to redeem all outstanding
     shares of Senior Stock or to refund or renew unsecured indebtedness) in
     excess of 20% of the Company's outstanding capital stock, surplus and
     secured indebtedness, or, with respect to unsecured indebtedness having
     maturities of less than 10 years, in excess of 10%
                                       10
 

     of outstanding capital stock, surplus and secured indebtedness. Payment due
     upon the maturity of unsecured debt having an original single stated
     maturity of 10 years or more is not regarded as unsecured debt with a
     maturity of less than 10 years until within three years of the maturity
     thereof, and each of the payments due upon any unsecured debt having an
     original stated maturity for the final serial payment of 10 years or more
     is not regarded as an unsecured debt of a maturity of less than 10 years
     until within three years of the maturity of the final serial payment.
 
     By the affirmative vote of the holders of a majority of the outstanding
     shares of Senior Stock at a stockholders' meeting held on January 25, 1989,
     the Company has been authorized, notwithstanding such limitations, to incur
     unsecured indebtedness, having maturities of not more than ten years, in
     excess of 10% of its capital stock, surplus and secured indebtedness,
     provided that (i) such indebtedness is issued on or before March 31, 1994,
     (ii) such indebtedness has maturities not later than March 31, 1995, and
     (iii) the limitation on all unsecured indebtedness of the Company to 20% of
     its capital stock, surplus and secured indebtedness is complied with.
 
     On December 15, 1993, a special meeting of holders of the Company's Common
     Stock and Senior Stock (Special Meeting) is scheduled to be held for the
     purpose of authorizing an amendment (Amendment) to the Company's
     certificate of incorporation relating to the limitation on indebtedness
     described above. If approved, and assuming the receipt of any necessary
     approval of the DPUC to be obtained subsequent to the meeting, the
     Amendment will eliminate the limitation on the incurrence or assumption of
     unsecured indebtedness having maturities of less than ten years in excess
     of 10% of capitalization, calculated as set forth above, but not in excess
     of 20% of capitalization. In the event the Amendment is not approved by the
     requisite vote of the holders of two-thirds of the shares of each class of
     the Company's stock (Common Stock voting as one class and the Senior Stock
     voting as a separate class), consideration will be given to a vote of the
     holders of the Company's Senior Stock to extend the Company's current
     five-year authorization to incur unsecured indebtedness above the 10%
     restriction for an additional ten-year period ending on March 31, 2004.
     Adoption of this proposal requires a majority vote of the shares of Senior
     Stock and not more than one-third of such shares voting against the
     proposal. NU has advised the Company that it intends to vote all of the
     shares of Common Stock of the Company, which constitute all such shares
     issued and outstanding, in favor of the Amendment.
 
     2. Issue, sell or otherwise dispose of any shares of then authorized but
     unissued Senior Stock or any other stock ranking on a parity with or having
     priority over the Senior Stock as to dividends or assets if (a) for a
     period of 12 consecutive calendar months within the 15 calendar months
     immediately preceding the month of issue Income Before Interest Charges (as
     defined) for said period available for the payment of interest (including,
     in any case in which stock is to be issued in connection with the
     acquisition of property, the Income Before Interest Charges of the property
     to be acquired) was not at least one and one-half times the sum of (i) the
     interest charges for one year on indebtedness to be outstanding immediately
     following the proposed issue, sale or other disposition, (ii) annual
     dividend requirements on shares of Senior Stock and stock ranking on a
     parity with or having priority over the Senior Stock outstanding and
     proposed to be issued and (iii) certain rental charges, or (b) such issue
     would bring the aggregate of the amount payable on involuntary liquidation
     of the Company with respect to all shares of Senior Stock and all shares of
     stock ranking on a parity with or having priority over the Senior Stock to
     an amount in excess of "junior stock equity" (as defined).
 
     Without the consent of the holders of at least two-thirds of the aggregate
voting rights represented by shares of the Senior Stock then outstanding, or at
least two-thirds of the outstanding shares of the class of Senior Stock affected
if only one such class is affected, the Company may not:
 
     1. Increase the authorized amount of the Preferred Stock or stock ranking
     on a parity with the Preferred Stock as to dividends or assets beyond
     9,000,000 shares and $450,000,000 aggregate par or stated value or increase
     the authorized amount of Class A Preferred Stock or stock ranking on parity
     with the Class A Preferred Stock as to dividends and assets beyond
     8,000,000 shares and $200,000,000 aggregate par or stated value (Article
     VI, Section3).
 
                                       11
 

     2. Authorize or issue any shares of any class of stock having priority over
     the Senior Stock as to dividends or assets or issue any shares of any such
     prior ranking stock more than 12 months after the date of the vote
     authorizing such prior ranking stock (Article VI, Section1).
 
     3. Change the rights, preferences or powers of the Senior Stock so as to
     affect adversely such rights, preferences or powers, provided that in no
     event may any reduction of the dividend rate or of amounts payable on
     redemption or liquidation with respect to any share of Senior Stock of
     either class be made without the consent of the holder thereof and that no
     such reduction with respect to shares of any particular series of either
     class of the Senior Stock may be made without the consent of all the
     holders of shares of such series (Article VI, Section2).
 
     The Senior Stock provisions require the consent of the holders of a
majority of the aggregate voting rights represented by shares of the Senior
Stock then outstanding for a merger or consolidation of the Company with or into
any other corporation or for a sale of all or substantially all of the Company's
assets unless such merger, consolidation or sale, or the issuance or assumption
of securities in the effectuation thereof, shall have been permitted under the
Public Utility Holding Company Act of 1935 (Article VII). The Connecticut Stock
Corporation Act presently requires, with minor exceptions, the affirmative vote
of the holders of at least two-thirds of the outstanding shares of each class of
the Company's capital stock, including the Preferred Stock and the Class A
Preferred Stock, each voting as a separate class, to approve such a merger,
consolidation or sale.
 
MISCELLANEOUS
 
     Except as otherwise expressly provided by law, the Senior Stock has no
preemptive or conversion rights and (except as provided with respect to a
particular series of either class of the Senior Stock) is not entitled to the
benefit of any sinking fund. See "Sinking Fund Provisions." Upon due issuance
and the receipt by the Company of the purchase price therefor, all shares of the
New Preferred Stock will be fully paid and nonassessable.

the New Securities against certain liabilities, including liabilities under the
Securities Act of 1933.
