YANKEE ENERGY SYSTEM, INC. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)



1)   GENERAL

     The accompanying unaudited consolidated financial statements
     should be read in conjunction with the Annual Report of
     Yankee Energy System, Inc. (the Company) on Form 10-K for
     the fiscal year ended September 30, 1997 (1997 Form 10-K),
     including the audited financial statements (and notes
     thereto) incorporated by reference therein and the Company's
     quarterly reports on Form 10-Q for the quarters ended
     December 31, 1997 and March 31, 1998.  In the opinion of the
     Company, the accompanying unaudited consolidated financial
     statements contain all adjustments (consisting only of
     normal recurring accruals) necessary to present fairly the
     financial position of the Company as of June 30, 1998, and
     its results of operations for the three and nine months
     ended June 30, 1998 and 1997 and cash flows for the nine
     months ended June 30, 1998 and 1997.  The results of
     operations for the three and nine months ended June 30, 1998
     and 1997 are not necessarily indicative of the results
     expected for a full year, due mainly to the highly seasonal
     nature of the gas business.


2)   ACCOUNTING FOR THE EFFECTS OF REGULATION

     The Company's wholly-owned subsidiary, Yankee Gas Services
     Company (Yankee Gas), is subject to regulation by the
     Connecticut Department of Public Utility Control (DPUC). 
     The Company prepares its financial statements in accordance
     with generally accepted accounting principles which includes
     the provisions of Statement of Financial Accounting
     Standards No. 71, "Accounting for the Effects of Certain
     Types of Regulation," (FAS 71).  FAS 71 requires a
     cost-based, rate-regulated enterprise such as Yankee Gas to
     reflect the impact of regulatory decisions in its financial
     statements.  The DPUC, through the rate regulation process,
     can create regulatory assets that result when costs are
     allowed for ratemaking purposes in a period other than the
     period in which the costs would be charged to expense by an
     unregulated enterprise.

     Following the provisions of FAS 71, Yankee Gas has recorded
     regulatory assets or liabilities as appropriate primarily
     related to deferred gas costs, pipeline transition costs,
     hardship customer receivables, environmental cleanup costs,
     income taxes and postretirement benefits costs.  The
     specific amounts related to these items are disclosed in the
     consolidated balance sheets.  For additional information
     about these items see the 1997 Form 10-K.

     Yankee Gas continues to be subject to cost-of-service based
     rate regulation by the DPUC.  Based upon current regulation
     and recent regulatory decisions, Yankee Gas believes that
     its use of regulatory accounting is appropriate and in
     accordance with the provisions of FAS 71.  
     
3)   EARNINGS PER SHARE
          
     In fiscal 1998, the Company adopted Statement of Financial
     Accounting Standards No. 128, "Earnings per Share" (FAS
     128), which changes the method for computing earnings per
     share and requires the Company to present basic and diluted
     earnings per share.  As a result, all prior periods have
     been restated to reflect application of FAS 128.  The effect
     of this accounting change on previously reported earnings
     per share data was immaterial.


4)   COMMITMENTS AND CONTINGENCIES
          
     The Company faces a number of contingencies which arise
     during the normal course of business and which have been
     discussed in Note 9 (entitled "Commitments and
     Contingencies") to the Consolidated Financial Statements
     included in the Company's 1997 Form 10-K Report.  Except as 
     disclosed below, for the nine months ended June 30, 1998,
     there have been no material changes in the matters discussed
     in Note 9, to the Company's 1997 Form 10K Report.
     
     Rate Review:  On July 9, 1997, the DPUC issued its decision
     in Docket No. 96-08-05.  The DPUC decision, which is not a
     rate order, called for a lowering of Yankee Gas' authorized
     Return on Equity (ROE) from 12.43 percent to 11.15 percent. 
     The DPUC believed that lower current interest rates and
     recently allowed rates of return for other Connecticut
     utilities justified a lower ROE for Yankee Gas.  On October
     1, 1997, the DPUC approved a settlement whereby Yankee Gas
     will credit approximately $3.2 million to firm sales
     customers through the Purchased Gas Adjustment (PGA) during
     fiscal year 1998.  As of June 30, 1998 the entire $3.2
     million has been accrued and approximately $2.9 million had
     been credited to firm sales customers.  The remaining $0.3
     million has been included in the Company's annual deferred
     fuel calculation and will be credited back to firm sales
     customers beginning in October 1998.  The settlement also
     allows Yankee Gas to maintain its base rates until the end
     of fiscal year 2000, resulting in an eight-year period in
     which Yankee Gas will have gone without an increase in its
     base rates.
                                               
     Legal Issues:  In November 1995, a purported class action
     suit was filed against Yankee Gas and the state's two other
     Local Distribution Companies (LDCs) by the Connecticut
     Heating and Cooling Contractors' Association, Inc. et al,. 
     The action alleges that the LDCs unfairly competed with
     licensed plumbers and contractors by performing customer
     service work using customer service employees who did not
     possess state trade licenses.

     On January 27, 1998, the judge in this matter struck 31 out
     of the plaintiffs' 32 counts contained in their complaint
     leaving only one count alleging violations of Connecticut's
     anti-trust statute.  The judge also noted that although the
     plaintiffs' action purports to be a class action, the
     plaintiffs have failed to obtain certification as such. 
     Thereafter, the plaintiffs' filed another purported class
     action against all three LDCs alleging unfair trade
     practices and additional separate actions against each LDC
     alleging various business torts.  While the ultimate
     resolution of the actions cannot be predicted, management
     does not expect that they will have a material adverse
     effect on the Company's consolidated results of operations
     or financial position.

     In fiscal 1996, Yankee Gas received revised property tax
     bills from the City of Meriden, Connecticut (the City).  The
     City is asserting a claim for approximately $5.0 million for
     back taxes and interest resulting from a retroactive
     reassessment and revaluation of Yankee Gas' personal
     property filings.  The City did not locate or identify any
     property which Yankee Gas omitted from its filings.  The tax
     bills reflect a reassessment of property at higher rates
     than those previously accepted by the City.  Yankee Gas is
     currently in the process of litigating this retroactive
     reassessment and the judge in this matter has recently
     recommended that the parties attempt mediation/arbitration
     of the issue.  Although it is anticipated that the outcome
     of this claim will not have a material impact on the
     Company, based on the information available at this time,
     management cannot predict what the ultimate impact might be.

     Tax Audits:  The Company is currently under audit by the
     State of Connecticut regarding its Gross Earnings Tax
     returns for the calendar years 1994, 1995, and 1996, by the
     City of Naugatuck, Connecticut regarding its Personal
     Property Tax Schedules for the years 1995, 1996, and 1997,
     and by the Internal Revenue Service regarding its Federal
     Income Tax Return for the calendar year 1995.  All of these
     audits are in preliminary stages, and therefore the Company
     does not have sufficient information to determine the
     amount, if any, of additional liability that may result from
     these proceedings.  However, the Company does not anticipate
     any of these audits to have a material effect on its
     financial position.
          

5)   FORWARD-LOOKING STATEMENTS

     This report may contain statements which, to the extent they
     are not recitations of historical fact, constitute
     "forward-looking statements" within the meaning of the
     Private Securities Litigation Reform Act of 1995 (Reform
     Act).  Such forward-looking statements involve risks and
     uncertainties. Actual results may differ materially from
     such forward-looking statements for reasons including, but
     not limited to, changes to and developments in the
     legislative and regulatory environments affecting the
     Company's business, the impact of competitive products and
     services, changes in the natural gas industry caused by
     deregulation and other factors, and certain environmental
     matters, as well as such other factors as set forth in the
     Company's Form 10-K for the year ended September 30, 1997.
     

6)   USE OF ESTIMATES
     
     The preparation of financial statements in conformity with
     generally accepted accounting principles requires management
     to make estimates and assumptions that affect the reported
     amounts of assets and liabilities and disclosure of
     contingent assets and liabilities at the date of the
     financial statements and the reported amounts of revenues
     and expenses during the reporting period.  Actual results
     could differ from those estimates.


7)   RECLASSIFICATIONS

     Certain prior year amounts have been reclassified to conform
     with current year presentation.





            REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS


To the Board of Directors and Shareholders of
     Yankee Energy System, Inc.:


We have reviewed the accompanying consolidated balance sheet of
Yankee Energy System, Inc. (a Connecticut corporation) and
subsidiaries (the Company) as of June 30, 1998, and the related
consolidated statements of income for the three-month and
nine-month periods then ended, and cash flows for the nine-month
period then ended.  These financial statements are the
responsibility of the Company's management.

We conducted our review in accordance with standards established
by the American Institute of Certified Public Accountants.  A
review of interim financial information consists principally of
applying analytical procedures to financial data and making
inquiries of persons responsible for financial and accounting
matters.  It is substantially less in scope than an audit
conducted in accordance with generally accepted auditing
standards, the objective of which is the expression of an opinion
regarding the financial statements taken as a whole. 
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material
modifications that should be made to the financial statements
referred to above for them to be in conformity with generally
accepted accounting principles.

We have previously audited, in accordance with generally accepted
auditing standards, the consolidated balance sheet of Yankee
Energy System, Inc. as of September 30, 1997 (not presented
herein), and, in our report dated November 7, 1997, we expressed
an unqualified opinion on that statement.  In our opinion, the
information set forth in the accompanying consolidated balance
sheet as of September 30, 1997 is fairly stated, in all material
respects, in relation to the balance sheet from which it has been
derived.

ITEM 2.   Management's Discussion and Analysis of Financial
Condition and  Results of Operations


RESULTS OF OPERATIONS

Consolidated net losses were $1.9 million for the three months
ended June 30, 1998 compared to $0.4 million for the same period
a year earlier.  The corresponding basic and diluted losses per
share were $0.18 and $0.04 for the three months ended June 30,
1998 and 1997, respectively.

Earnings for the third quarter of fiscal year 1998 decreased
primarily due to weather that was 29 percent warmer than the same
period last year and 14 percent warmer than normal.  The Company
estimates that warmer than normal weather reduced earnings by
$0.9 million or $0.09 per share in the current quarter as
compared with the prior year's quarter which experienced colder
than normal weather which impacted earnings by $1.5 million or
$0.15 per share.  In addition, earnings decreased by
approximately $0.4 million or $0.04 per share for the three
months ended June 30, 1998, due to customer bill credits which
were the result of a rate review settlement reached with the DPUC
in October 1997.  Yankee Energy Services Company (YESCo), the
Company's major non-regulated subsidiary, was positively affected
by the continued demand for HVAC and control services.  These
positive effects were offset by delays in gaining regulatory
approvals for power projects.

For the nine months ended June 30, 1998 both the diluted and
basic earnings per share were $1.72 compared to $2.10 for the
nine months ended June 30, 1997.  The decrease in earnings is due
to customer bill credits of approximately $1.9 million or $0.18
per share for the nine months ended June 30, 1998 and weather
that was 7 percent warmer than the same period last year and 10
percent warmer than normal.  Management estimates that warmer
than normal weather reduced earnings by $4.5 million or $0.43 per
share for the nine months ended June 30, 1998, and by $0.9
million or $0.9 per share for the nine months ended June 30,
1997.


COMPARISON OF THE THIRD QUARTER OF FISCAL 1998 WITH THE THIRD
QUARTER OF FISCAL 1997 


OPERATING REVENUES

Utility revenues decreased $12.0 million, or 21 percent, in the
third quarter of fiscal 1998 compared with the same period in the
prior fiscal year.  This decrease was partially offset by a $6.9
million increase in operating revenues from nonutility
operations.  The components of the change in operating revenues
are as follows:

                         _______   ______      _____ 


                         
                         
The change in utility revenues was due primarily to weather that
was 29 percent warmer than the prior year and customer bill
credits of $0.7 million  which are reflected in the third quarter
of fiscal 1998.  In addition, an increasing number of commercial
and industrial customers continue to shift from sales gas to
transportation service resulting in a decrease in operating
revenue.  Interruptible revenues have decreased primarily as a
result of lower oil prices in the current third quarter compared
to the same period in the prior year.  The increase in nonutility
revenues in the third quarter of fiscal 1998 compared to the same
period in fiscal 1997 is primarily due to additional activity
resulting from acquisitions. 

OPERATING EXPENSES

Total operating expenses decreased $3.0 million in the third
quarter of fiscal 1998 compared with the same period in the prior
year as a result of the following items:

     -    Cost of gas decreased $9.1 million, or 30 percent, for
          the three months ended June 30, 1998 compared to the
          three months ended June 30, 1997 due primarily to a 21
          percent reduction in utility revenues.

     -    Cost of goods sold increased $5.8 million in the third
          quarter of fiscal 1998 compared to the third quarter of
          fiscal 1997 due to increased nonutility activity
          resulting primarily from  acquisitions.

     -    Operations and maintenance expenses increased $0.6
          million, primarily due to increases in payroll, data
          center operations and  expenses related to
          non-regulated subsidiary activity, partially offset by
          a decrease in pension expense from the utility
          subsidiary.  

     -    Depreciation and amortization expense increased $0.3
          million, primarily due to additions in plant, property
          and investments.    
     
     -    Taxes other than income taxes decreased $0.6 million,
          primarily due to lower Connecticut gross earnings taxes
          in fiscal 1998 as a result of the reduction in
          revenues.

INTEREST EXPENSE

Interest expense increased $0.6 million primarily due to higher
short-term debt outstanding.  This increase was partially offset
by a decrease in long-term debt interest expense, primarily due
to refinancing of long-term debt at more favorable rates.



INCOME TAXES

Federal and state income taxes decreased $1.4 million primarily
due to lower pre-tax income for the three months ended June 30,
1998 compared to the three months ended June 30, 1997.

NINE MONTHS OF FISCAL 1997 


OPERATING REVENUES

Utility revenues decreased $29.8 million, or 11 percent, in the
first nine months of fiscal 1998 compared with the same period in
the prior fiscal year.  This decrease was offset by a $17.2
million increase in operating revenues from nonutility
operations.  The components of the change in operating revenues
are as follows:

The change in utility operating revenues primarily reflects
weather that was 7 percent warmer in fiscal 1998 and customer
bill credits of $3.2 million.  In addition, an increasing number
of commercial and industrial customers continued to shift from
sales gas to transportation service resulting in a decrease in
operating revenue.  Interruptible revenues have decreased
primarily as a result of lower oil prices in the nine months
ended June 30, 1998 compared to the same period in the prior
year.  Offsetting these changes was an increase in nonutility
revenues resulting from acquisitions. 

OPERATING EXPENSES

Total operating expenses decreased $8.0 million in the first nine
months of fiscal 1998 compared with the same period in the prior
year as a result of the following items:

     -    Cost of gas decreased $23.0 million, or 15 percent, for
          the nine months ended June 30, 1998 compared to the
          nine months ended June 30, 1997 due primarily to a 11
          percent decrease in utility revenues.
  
     -    Cost of goods sold increased $13.8 million in the first
          nine months of fiscal 1998 compared to the first nine
          months of fiscal 1997 due to increased nonutility
          activity.

     -    Operations and maintenance expenses increased $2.1
          million, primarily due to increases in data center
          operation expense and expenses related to nonutility
          activity, offset by decreases in uncollectible,
          maintenance and pension expenses, related to the
          utility subsidiary.   

     -    Depreciation and amortization expense increased $1.3
          million, primarily due to additions in plant, property
          and investments.    
     
     -    Taxes other than income taxes decreased $2.1 million,
          primarily due to lower Connecticut gross earnings taxes
          in fiscal 1998 as a result of the reduction in
          revenues.

INTEREST EXPENSE

Interest expense increased $0.9 million mainly due to higher
short-term debt outstanding.  This was partially offset by a
decrease in interest expense associated with lower long-term debt
outstanding and lower interest rates.

INCOME TAXES

Federal and state income taxes decreased $1.7 million primarily
due to lower pre-tax income for the nine months ended June 30,
1998 compared to the nine months ended June 30, 1997.

LIQUIDITY AND CAPITAL RESOURCES

Cash and temporary cash investments at June 30, 1998 totaled $3.1
million.  Principal sources of cash for the nine months ended
June 30, 1998 were from operations, common stock issued through
the dividend reinvestment plan, and short-term debt.  These funds
were used primarily for changes in working capital, dividend
payments, and investment in plant, property and investments. 
Expenditures for investment in plant, property and investments
totaled $28.1 million for the first nine months of fiscal 1998,
reflecting a $5.7 million increase over the first nine months of
fiscal 1997.

The seasonal nature of gas revenues, inventory purchases and
construction expenditures create a need for short-term borrowing
to supplement internally generated funds.  As of June 30, 1998,
Yankee Gas had a revolving line of credit of $60 million with a
group of five banks.  Under the agreement, funds may be borrowed
on a short-term revolving basis using either fixed or variable
rate loans.  Yankee Gas also had uncommitted credit lines of $27
million as of June 30, 1998.  At June 30, 1998, Yankee Gas had
$26.7 million outstanding under its agreements. Yankee Energy had
$14.0 million outstanding at June 30, 1998 under its $25 million
committed line of credit which is used to fund acquisitions and
other capital requirements of the unregulated businesses. 
Management is currently contemplating new long-term debt
financing in fiscal 1999 for the purposes of replacing a portion
of the existing short-term debt outstanding and to refinance
Series A, Tranche D which becomes redeemable by the Company in
August 1999.

The long-term credit needs of Yankee Gas are being met by a first
mortgage bond indenture which provides for the issuance of bonds
from time to time, subject to certain issuance tests.  At June
30, 1998, indenture requirements, including the required coverage
ratio, would allow for the issuance of an additional $210 million
of bonds at an assumed interest rate of 6.6 percent.

Yankee Gas has entered into fixed revenue-rate contracts with two
customers for the delivery of natural gas.  Yankee Gas has hedged
these commitments with the purchase of natural gas swaps.  In
order to satisfy certain provisions of the arrangement, Yankee
Gas has provided a letter of credit for $1.5 million, as of June
30, 1998.  The Company's results of operations are unaffected by
the hedge transaction given that it passes through the cost of
the hedge to either the commodity trading firm or its customer
depending on the difference in the fixed and floating prices for
gas.

Yankee Gas expects to incur expenditures for coal tar remediation
efforts, which is more fully discussed in Note 9 to the
Consolidated Financial Statements, included in the Company's 1997
Form 10-K Report.  Yankee Gas  expects to finance such
expenditures through a combination of internally generated funds,
short-term debt, and through insurance settlements, which have
totaled $9.6 million as of June 30, 1998.

The Company is currently implementing new systems and enhancing
existing systems to address year 2000 issues.  As part of that
process, a detailed inventory of all hardware and software
currently utilized by the Company has been prepared and a
timetable has been established to commence testing of all
applications.  Management believes that all system changes will
be installed and tested prior to the manifestation of year 2000
issues.  However, if such changes are not completed timely, the
year 2000 issue may have a material impact on the operations of
the Company.  Currently, all such charges associated with system
enhancements have and will continue to be expensed and the costs
of new systems will be capitalized as appropriate and are not
expected to be material.

One of Yankee Gas' largest customers, the Foxwoods Hotel and
Casino (Foxwoods), operated by the Mashantucket Pequot Indian
Tribe, generates approximately $650,000 in annual margin.  The
City of Norwich, Connecticut has begun construction of a pipeline
extending from their distribution system to Foxwoods.  This will
provide an alternative source of supply to the Mashantucket
Pequots.  Yankee Gas believes that it will have the opportunity
to compete to retain gas throughput to Foxwoods.

RM Services (RMS), a wholly-owned subsidiary of the Company,
recently formed an alliance with Dun & Bradstreet Receivable
Management Services (D&B).  The alliance allows RMS to extend its
collection activities in the transitioning energy,
telecommunication and other industries by supporting the
extensive network of D&B in its pursuit of additional consumer
business.  RMS has extensive experience and specialized skills in
residential utility collection practices and computer-aided
calling technology. 

RECENT DEVELOPMENTS

On May 6, 1998, the Company filed an application with the DPUC to
discontinue on demand, non-contract service work.  Hearings have
been held on this matter and the Company is presently awaiting a
decision by the DPUC.  Regardless of the outcome, this change is
not expected to have a material impact on the Company's financial
condition.

The Company's wholly-owned, nonregulated subsidiary, Yankee
Financial Services Company, has recently sold its receivable
portfolio to an independent party and recognized a small gain as
a result of the sale.  The transaction was recorded as a sale for
financial reporting purposes.
