Chairman's Letter:

A Letter from Branko

This year -- a year of transition for your company, Yankee Energy
System, Inc. -- earnings from our regulated subsidiary, Yankee
Gas Services Company, were strong (despite the warm weather). Yet
losses from last year s startup diversification effort in Yankee
Energy Services Company (YESCo) meant our total earnings for the
year were less than anticipated.

The earnings for 1997 of $1.62 a share were down from the
previous year s earnings of $2.10, based on warmer weather and
other variables. The prior year s figure benefited from a $0.24
per share gain on the sale of our interest in the Iroquois
Pipeline. As an additional point of reference, 1995 earnings were
$1.20 per share (this included a one-time charge of $0.30 per
share related to the company s business re-engineering efforts).

Focused strategy, improved management

I take responsibility for our results and wish to inform you that
Yankee Energy is applying the lessons learned from our experience
this past year. As we begin a new fiscal year, strategic focus
has been sharpened, managerial improvements have been made, and
operating performance has improved. Our strategy to increase
shareholder wealth has not deviated from its path. We will
continue to improve the efficiency and sales effectiveness of
Yankee Gas Services Company while creating new earnings in our
YESCo subsidiary by focusing on energy-related mechanical
services, first in Connecticut and then in the rest of New
England.

This strategy fits well with the changes now driving the energy
sector of the U.S. economy. As I reported in last year s letter,
all indicators point to increased competition in the energy
industry. Thus, Yankee Energy s prospects continue to be
influenced by often unpredictable changes in state and federal
regulation of natural gas and electricity.

Deregulation and increased opportunities

Last year, competition was introduced in Connecticut by a
Department of Public Utility Control (DPUC) decision allowing
commercial and industrial customers to purchase commodity gas on
the market. This year, the DPUC has opened a proceeding to take
evidence and testimony on the issue of residential customer
choice in gas purchased from other marketers. Since Yankee Gas
has successfully implemented transportation services to
commercial and industrial customers, we are well-positioned to
provide residential gas transportation services. This new service
will be boosted by use of our automatic meter reading capability
and new informational technology investments.

Changes in electric regulation -- particularly new laws
facilitating distributed electric generation -- will present a
number of opportunities for Yankee Energy subsidiaries. As the
largest gas distribution system in Connecticut, Yankee Gas is
ready to provide gas sales or gas delivery services to newly
constructed gas-fired electric generation facilities. Any new
construction of small distributed power plants also creates a
market for YESCo, which can provide installation, operation and
maintenance services for these types of energy conversion
technologies.

Diversification moves Yankee closer to customers

In contrast to the strategies of many other utilities, Yankee
Energy System has chosen to offer "technicians and trucks"
through our YESCo subsidiary. Many national companies advertising
"energy services" through telemarketing or direct mail are not
able to provide these capabilities. Yankee Energy System s
diversification strategy is to extend services beyond gas
delivery. This means we will offer services on the customer s
side of the meter for energy conversion, control, and gas-using
devices. Thus, YESCo revenues will increase by providing highly
trained and well-equipped field personnel to meet customers 
needs on-site.

YESCo has chosen as its initial service area a region that will
benefit from the proximity of Yankee Gas Services. YESCo has
chosen as its market segment industrial and commercial targets
whose need for mechanical and energy-related services will,
within a short time, enable YESCo to become a regional market
leader. To enhance our competitive position further, YESCo
customers will have the convenience of one-stop financing from
its affiliate, Yankee Financial Services Company.

Our mission is to increase shareholder value. Yankee Energy will
accomplish that mission by the creation of service offerings that
will provide our customers with "imaginative and responsive
energy solutions."

Everyone at Yankee Energy clearly understands that mission. We
believe our plan to be well-designed with an appropriate balance
of risk and growth. Recent additions to management have
strengthened our organization and increased our prospects for
financial success even more.

I am keenly aware of your expectations as shareholders and of my
own responsibilities as Chief Executive Officer of your company.
Please feel free to contact me at any time with your critiques,
comments, or suggestions concerning your company s performance.

Upper Right:   We're closer to customers, and our sales show it.


Growth is the principal indicator of the health of any business,
and 1997 sales results clearly show the strength of our anchor
company, Yankee Gas, and the improved economic conditions in the
areas we serve. We have reorganized our sales force under
experienced sales and marketing professionals and doubled our
historic rate of customer growth, adding more than 2,300 new
customers. We exceeded our sales growth projections by more than
52 percent. Even as we meet the growing demands of almost 160,000
residential energy customers, we added 30 percent more
appliance-service customers in 1997.

Yankee Gas also was Connecticut s leader in promoting firm
transportation services, making our infrastructure available to
customers who choose to buy their own gas, and rely upon our
distribution system to deliver it. We identified gas-fired
electricity generation opportunities and effectively marketed
them to businesses throughout the state. Our gas cooling, air
compression, infrared heating and natural gas vehicle programs
all moved forward.

As we grew the business, we tightly controlled operating,
maintenance, and capital expenditures. Aggressive goals set for
all areas of operations were mostly met or exceeded.

That was last year. To succeed in 1998 and the longer term, we
need to have a clear understanding of what we are and must be to
our customers. We are a quality provider of natural gas
distribution and utilization services. We sell gas to those
customers who want to buy from us, and we deliver gas for other
customers who want to buy their own gas. We provide appliance and
equipment installation, maintenance and service directly to our
residential customers.

To prosper in the future, Yankee Gas must consistently be named
by customers as one of the top service companies with which they
do business. We no longer compare ourselves only to public
utilities, because our customers ceased doing that long ago. We
are now compared to the package delivery company, the lawn
service, and the local building contractor. Our service must
rival that of the "best in its class" of any type of company
serving consumers.

Because the price of energy is a primary customer concern, we
must keep our prices competitive with those of other energy
providers. We will do this through aggressive cost management and
sales efforts focused in areas where we already have distribution
facilities. Yankee Financial will continue to support our ability
to make natural gas an affordable option.

As changes in regulation require our customers to make choices,
we will be the source for clear, reliable information. Technology
does and will continue to play a major role in our customer
interactions, as is evidenced by our comprehensive Web site and a
new customer information system, scheduled for completion next
Fall. But technology will not replace the motivated,
well-trained, and courteous employees who have come to exemplify
Yankee Gas. Rather, it will enable them to delight our customers.

Customer delight, not customer satisfaction, is the new target at
which we are aiming.

Yankee Energy Services Company (YESCo) is being positioned in the
marketplace to provide a full range of energy equipment
mechanical services to commercial, industrial, and institutional
customers through YESCo s three divisions: Power, Controls, and
Services. 

YESCo s Power division designs, builds and maintains on-site
facilities for the production of thermal and/or electric power.
This includes fuel cells, of which YESCo Power installed two in
the fourth quarter of fiscal 1997, and began its third
installation in the first quarter of 1998. YESCo Controls
specializes in the engineering, installation, and maintenance of
building control systems. Controls is an authorized installer of
Andover Controls, a leading building controls product that we are
now installing in major projects for customers such as Southern
New England Telecommunications (SNET) and the University of
Connecticut. YESCo Services now operates out of three locations,
two in Connecticut and one in Massachusetts, to provide
comprehensive HVAC, boiler, and refrigeration equipment services
and installation.

In fiscal 1997, YESCo incurred startup costs at new locations
associated with building a sales and marketing infrastructure,
and initiated negotiations that led to acquisitions just after
the end of the fiscal year. Several on-site energy generation
projects expected to begin in fiscal 1997 were also delayed to
early 1998. Nonetheless, our identity as a provider of
comprehensive energy-related mechanical services is taking shape
as we continue to provide excellent service.

Substantial progress was made against our aggressive multi-year
business plan. In the third quarter we established two additional
operations service centers, one in southern Connecticut and one
in eastern Massachusetts. Late in the fourth quarter we completed
two acquisitions that enhance our technical capabilities in both
our Controls and Services divisions. 

Our goal is to become the largest provider of comprehensive
mechanical services in Connecticut and adjacent markets. In
fiscal 1998 we plan continued growth internally through targeted
sales efforts and acquisitions. All the necessary managerial,
financial, and cultural components are in place to enable us to
create real shareholder value and continue our acquisitions
program.

Our strategy of "technicians and trucks" dispatched to provide
on-site solutions for customers remains sound. In keeping with
the character of Yankee Energy System, YESCo is set for
long-term, steady growth.

Thanks to a state-of-the-art Microsoft NT-based client/server
system, more customer information will be at the fingertips of
Yankee Gas service personnel, helping them serve customers more
quickly and accurately. The system, created by IBM Global
Services, is a first in the natural gas industry and will provide
fast access to data on customer billing, sales, credit, repairs
and maintenance. Yankee believes the system will enhance the
company s growth strategies.

Charles Gooley, president of Yankee Gas, pointed out that
"utility customers will compare their utility providers' service
to all other service providers. The IBM-CSS system will help us
provide the service that will distinguish us from everyone else."
The installation is scheduled for completion in late 1998.

The growth of gas-appliance service contracts sold by Yankee Gas
skyrocketed this past year, exceeding all expectations. "We
marketed more aggressively than ever," said Yankee Vice President
of Marketing Steve Laden. "Seasonal specials and add-on contracts
for installations, conversion projects and new homeowners
resulted in thousands of new service contract customers."

Laden added that service contracts do more than provide another
revenue stream. "Having a contractual relationship with customers
encourages them to communicate with us," he said. "It s another
way of listening to them and staying in touch with what they
want."

CAD keeps Yankee Service running on time

When a request for service comes in to Yankee Gas, vehicles are
responding more efficiently because of Computer Aided Dispatch
(CAD). The system, installed last summer, coordinates a fast
response by linking service headquarters to computer terminals in

service vehicles. Yankee personnel are directed to the customer 
and already informed about the nature of the problem when they
arrive. As the Yankee customer base expands in number and in
geographic distribution, CAD will keep Yankee service pointed in
the right direction.



Yankee OnCall completes customer service loop

Graphic of Yankee OnCall logo

Yankee Gas has traditionally provided natural gas to its
customers and provided service or repair work when needed. But
when residential customers wanted to buy and install natural-gas
equipment, Yankee could only recommend a contractor. 

Yankee OnCall changes all that. Yankee OnCall is an
equipment-acquisition and installation service for residential
customers. "The customer benefits from better, more competitive
service through Yankee," said David Ferrante, director of
customer service. "And we re now able to provide energy solutions
seamlessly, from acquisition to installation, delivery, service,
and repairs."

Yankee helps Martha Stewart feel right at home

Center left:   Photo inset of Martha Stewart cooking at stove

Center right:

When it comes to the quest for the perfect home, one woman leads
the way. Martha Stewart has the last word on how to address
domestic dilemmas, from making artichoke dip to baking zucchini
bread. And she wouldn't  cook with anything but natural gas.

"For precision cooking, nothing comes close to natural gas," she
said from her studio in Norwalk, where Yankee recently completed
a conversion that enabled the construction of two
commercial-grade kitchens. With gas now on-line for her new daily
television show, "Martha Stewart Living," the star will saute,
bake, broil, and boil with the accuracy for which she s known.

"We worked closely with our customer on this project," said
Yankee Gas Sales Representative Mike Collins. "We designed
subfloor lines to suit the studio layout. Once it was done, we
convinced Ms. Stewart to make her heating system natural gas,
too, and converted the whole building."  Look for Martha
Stewart s new syndicated television show, and look for the Yankee
Gas name when the credits roll.


Yankee answers the need for cleaner power

The problem at the Laurel Gardens apartments wasn't that oil heat
was costly. It was that oil heat created maintenance problems and
environmental issues for the community.

Enter Rick Hughes, the Yankee Gas sales representative who called
the Director of Danbury's Housing Authority last February. He
showed the Director how natural gas could help improve air
quality, and today has converted 90 units in five apartment
buildings. "The tenants get cleaner heat. And Yankee gets more
satisfied customers on-line," said Hughes. Yankee Gas is now
focused on similar properties in Danbury -- and the other 67
towns in the service area -- that could use cleaner energy.

Stonegate finds a cure for the common cold


Stonegate was a cold neighborhood. Ninety single-family Stamford
homes, all with poor insulation, all heated by electric heat
pumps. Each winter, kids got sick and the electric bills soared.

Yankee Gas Sales Representative Greta Mead connected with a
resident who wanted to sell his home, but because of the electric
heat, couldn't get the price he wanted. Together, they attended
neighborhood meetings, stuffed flyers in mailboxes, and
discovered a market ripe for natural gas.

"It was a domino effect," said Mead. "Momentum built on word of
mouth, and eventually we converted 60 of the 90 homes to natural
gas." Now natural gas furnaces, fireplaces, and water heaters are
getting hot. And kids are staying warmer.

Transportation Services keeps Yankee right in the middle of
things

As Yankee Gas "unbundles," separating its gas supply and gas
delivery services, more of Yankee s commercial and industrial
customers will purchase natural gas on the open market. The move
is expected to reduce Yankee s role as seller of natural gas, and
open up new sales opportunities in gas transportation. Hence the
formation of a new department: Transportation Services.

Transportation Services makes Yankee a partner with customers who
need gas and with those who supply gas, by providing the
infrastructure that enables gas to arrive at its destination. No
matter where customers buy their gas, Yankee gets it there. 

The new department will also coordinate with Sales to identify
transportation-related business opportunities. "We can
communicate with people who need gas, and people who supply it,"
said Richard Tardif, manager of Transportation Services. "This
will keep our sales staff supplied with the market information
they need, and administer customer requests more effectively."

EBB and flow. 
On-line natural gas ordering heats up.

Now that marketers are opening up natural gas sales, they rely on
Yankee Gas more than ever for timely delivery of the product. For
this reason, Yankee has established an Electronic Bulletin Board,
operational since last summer.

The EBB keeps communications with marketers constant, current,
and paperless. Orders for natural gas arrive instantly. Marketers
receive daily summaries of account activity. The database
information is entered once (instead of twice, under the previous
faxing method). And, since EBB uses the Internet, no additional
hardware or software is required. Bottom line:  Customers get the
gas they need at competitive prices when they need it.

Two markets open up for natural gas.


Infrared heats up; air compression performs under pressure.


Background text:    infrared


Owners of large facilities like warehouses, garages, and airplane
hangars have traditionally paid a premium to keep their vast
space warm enough to work in during cold, drafty winter months.
Until recently, that is. 

Natural gas-based infrared heating is now replacing older, colder
convection heating systems by putting warm air into cold work
areas. Infrared heaters heat buildings the same way the sun heats
the Earth s surface. Ceiling-mounted units radiate heat that
warms walls, floors, equipment and people. Comfort is increased
and heat loss is minimized. This explains why infrared heat is
now warming an Air National Guard hangar, a large auto-service
garage, and a manufacturing facility, all in Connecticut. 

Other firms are recognizing the benefits of natural gas as a
power source for air compression, important in many manufacturing
processes.  Natural gas-fired air compression is cheaper than
electricity, and more reliable, too, since it keeps manufacturers
going during power outages. These are just a few reasons why
Yankee Gas sees great potential in both these technologies, and
will market them aggressively in 1998.

NGV's hit the road

Natural Gas fleets expand


United Parcel Service and the U.S. Postal Service have added
natural gas-powered trucks to their Connecticut fleets, leading
the movement toward more fuel-efficient vehicles on our roads and
providing Yankee Gas Services sustained growth in the business of
engine conversions and fuel supply.

Federal laws mandate that certain fleets begin using alternative
fuels, so companies like UPS and the Postal Service are preparing
for the future. Ford, GM, and Chrysler all have plans for natural
gas vehicle (NGV) production as well.

For many companies, the reasons go beyond federal law. Natural
gas is less expensive -- about 90 cents a gallon -- and
cleaner-burning than gasoline, emitting approximately 90 percent
less carbon monoxide. Maintenance costs are lower and safety is
higher, since natural gas combusts at twice the temperature of
gasoline. That s smart driving.

NGVs are especially well-suited to fleet service, since such
vehicles rely on central fueling stations, of which Yankee now
has five in Connecticut. The latest, at Danby's Exxon station in
Meriden, was constructed by Yankee Gas Services last year, adding
a critical centrally located link in the state s natural gas fuel
network. Check out our web site for other locations.

Natural gas goes in, premium AC power comes out.

Fuel cells first caught the attention of NASA, which is always
looking for new ways to supply power in outer space. Back here on
Earth, YESCo is marketing fuel cell technologies for business,
highlighting the company s drive to fill the demands for
non-traditional, reliable, premium power generation. Fuel cells
are currently operating at the Naval Submarine Base in Groton as
well as Yankee s corporate headquarters.

Fuel cells create AC power by separating the hydrogen and oxygen
in natural gas. Thermal energy is also produced, and can be
recovered and re-used. The power output from one fuel cell can
reach 200 kilowatts at 85 percent efficiency, enough power for
about 150 homes.

Right now the up-front cost of fuel cells is steep, but the
federal government subsidizes their development, making them more
affordable. Still, the appeal of fuel cells remains high. They
ensure clean, high-quality power even during power outages,
eliminate the need for expensive backup systems, and because the
current is steady, fuel cells extend the life of the equipment
they power. Natural gas fuel cells produce no emissions, so
they re easy on Mother Nature. 

As the demand for fuel cells in the premium power market  grows,
YESCo will be there to meet it.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

Financial Condition

OVERVIEW

Yankee Energy System, Inc. (YES or the Company) headquartered in
Meriden, Connecticut, is a diversified company specializing in
the distribution, conversion, and control of energy to meet our
customers' needs.  Our principal operating subsidiary is Yankee
Gas Services Company (Yankee Gas).  Yankee Gas provides retail
distribution of natural gas to a service area of 68 cities and
towns in Connecticut.  The Company's other operating subsidiaries
support our core business in natural gas, or allow us to expand
our growing businesses in energy-related services.  Yankee Energy
Services Company (YESCo) provides comprehensive energy-related
services through three principle divisions.  YESCo Power designs,
builds and maintains on-site facilities for the production of
thermal and/or electric power.  YESCo Controls is in the business
of engineering, installing, and maintaining building control
systems.  YESCo Services provides comprehensive HVAC, boiler and
refrigeration equipment services and installation.  Other
subsidiaries support the operations of Yankee Gas and YESCo. 
NorConn Properties, Inc. (NorConn) owns selected system real
estate, which it leases to Yankee Gas.  Yankee Energy Financial
Services (Yankee Financial) provides energy equipment financing. 
R.M. Services, Inc. (RMS) provides receivables management
services.

The Company reported consolidated net income of $16.9 million, or
earnings per share of $1.62, for its fiscal year ended September
30, 1997.  This compares with consolidated net income of $21.9
million and $12.4 million, reflecting earnings per share of $2.10
and $1.20, respectively, for fiscal years ended September 30,
1996 and 1995.  Fiscal 1996 earnings include a gain of $2.5
million or an after-tax effect of $0.24 per share resulting from
the Company's sale of its Iroquois Gas Transmission System
(Iroquois) investment.  Fiscal 1995 earnings reflect a one-time
operating charge of $5.4 million related to the Company's
business transformation efforts, or an after-tax effect of $0.30
per share.  Earnings for fiscal year 1997 decreased primarily due
to operating losses incurred by the Company's non-regulated
subsidiaries.  Delays in bringing new business on line and
integrating these companies into the Yankee Energy organization
have contributed to losses which are expected to be eliminated in
the next fiscal year.  These losses were partially offset by
strong operating performance at Yankee Gas during the fiscal year
due primarily to a reduction in Operation and Maintenance expense
principally as a result of cost controls implemented by the
Company.  The increase in 1996 earnings from fiscal 1995 was due
primarily to colder weather in fiscal 1996, the gain realized on
the sale of the Company's 10.5 percent equity interest in
Iroquois, and lower expenses relating to the Company's business
transformation.

Earnings on the Company's investment in Iroquois for the first
six months of fiscal 1996 were approximately $1.5 million and
contributed $0.14 to earnings per share as compared to $0.4
million in fiscal 1995, or $0.04 per share.  On April 30, 1996,
the Company announced the sale of its entire 10.5 percent
interest in Iroquois.  Earnings for fiscal 1996 reflect a $2.5
million net after-tax gain from the sale, or $0.24 per common
share, realized in the third quarter of fiscal year 1996.  Thus,
total earnings related to the investment in Iroquois, including
the gain on sale, were $0.38 per common share.  

The Company increased dividends paid per share to $1.32 in 1997,
up 3.1 percent from the $1.28 per share in 1996, the seventh
straight year the Company has increased its dividend.

Fiscal 1997 earnings per share are based on 10,451,165 weighted
average common shares outstanding.  Earnings per share were based
on 10,435,231 and 10,322,447 weighted average common shares
outstanding for fiscal years 1996 and 1995.  During fiscal 1997,
the Company issued 4,860 new shares of common stock under its
Long-term Incentive Plan.  In fiscal 1996, the Company issued
52,212 new shares under its Shareholder Investment Plan and 820
shares under its Long-term Incentive Plan.


REGULATORY MATTERS 

On August 25, 1996, Yankee Gas filed an application with the
Connecticut Department of Public Utility Control (DPUC) for a
Financial and Operational Review (Review).  This Review was
required under Connecticut statute since Yankee Gas had not
undergone a rate proceeding within the previous four years. 
Yankee Gas' last rate approval was on August 26, 1992, and this
Review was necessary to comply with the statute.  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 Clause (PGA),
during the period November 1997 through March 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 to
its base rates.

On January 3, 1996, the DPUC issued a Final Decision in reopened
Docket No. 92-02-19 to approve a rate agreement Yankee Gas
reached with the Office of Consumer Counsel (OCC).   The
agreement states that Yankee Gas may apply a portion of credits
received from pipeline refunds, excess interruptible margin,
deferred gas costs, capacity release agreements and off-system
sales margin to reduce or eliminate certain deferred regulatory
assets.  These credits are provided by a mechanism established by
the DPUC for the Connecticut Local Distribution Companies (LDCs)
to recover the gas supply transition costs relating to Federal
Energy Regulatory Commission (FERC) Order No. 636.

Through September 30, 1997, Yankee Gas has paid approximately
$19.5 million of gas supply transition costs and an additional
$3.5 million are anticipated.  To date, Yankee Gas has collected
$44.2 million through a combination of credits received from
pipeline refunds, capacity release agreements, deferred gas
costs, off-system sales margin, and excess interruptible margin. 
These excess collections of approximately $24.7 million have been
applied against certain regulatory assets in accordance with the
January 3, 1996 DPUC decision.

On August 2, 1995, the DPUC issued a Final Decision in Docket No.
94-11-12, DPUC Review of Connecticut Local Distribution
Companies' Cost of Service Study Methodologies.  The DPUC
investigated the issues surrounding the development of firm
transportation (FT) rates at the state level in response to FERC
Order No. 636.  The Decision provided guidelines for the
development of FT rates to be offered by the state's three LDCs. 

On January 24, 1996, the DPUC issued a Final Decision on Docket
No. 92-02-19 Reopen I.  This Decision enabled Yankee Gas to
implement FT rates and services as contemplated in the DPUC
August 2, 1995 decision referenced above.  The Decision allows
Yankee Gas to offer a broad array of service options to
commercial and industrial FT customers.  Yankee Gas implemented
these new FT rates and services on April 1, 1996, and as of
September 30, 1997, Yankee Gas had approximately 1,460 customers
under the new FT service.  Existing customers who switch to
transportation tariffs will result in decreased revenues for
Yankee Gas as that portion of revenues representing gas costs
will now be borne directly by those customers who buy their gas
directly.  Yankee Gas does not expect customer conversions to
transportation services to affect its net income because the cost
of gas has traditionally been a pass through item with no income
impact.

RESULTS OF OPERATIONS

OPERATING REVENUES

Operating revenues decreased $14.9 million from 1996 to 1997 and
increased $45.9 million from 1995 to 1996.  The components of the
change in operating revenues for the past two years are provided

                                   _____               _____




The change in operating revenues primarily reflects a decrease in
firm sales volumes of approximately 10.5 percent in fiscal 1997
compared to fiscal 1996. This change primarily related to the
shift of firm sales to firm transportation and a decrease in
residential sales volumes related to warmer weather.  Firm
transportation increased approximately $7.2 million from 1996 to
1997.  The increase in firm and other revenues from 1995 to 1996
was due primarily to weather that was 13 percent colder in 1996,
partially offset by an 11.5 percent decrease in off-system sales,
interruptible sales and transportation from 1995 to 1996. 
Revenues from non-regulated operations increased $5.2 million
from 1996 to 1997 and $0.9 million from 1995 to 1996 due to the
growth of nonutility subsidiaries during those years.

Gas cost recoveries decreased in fiscal 1997 compared to fiscal
1996 due to lower firm sales, offset by higher per-unit gas
costs.  Gas cost recoveries increased in fiscal 1996 compared to
fiscal 1995 due to higher firm sales and higher per-unit gas
costs.  

OPERATING EXPENSES


Total operating expenses decreased $11.2 million in 1997 compared
to 1996 and increased $34.1 million in 1996 compared to 1995 as a
result of the following items:

     Cost of gas decreased $16.4 million in 1997 compared to 1996
     and increased $33.8 million in 1996 compared to 1995. 
     Yankee Gas defers differences between actual purchased gas
     costs and the current cost recovery and recovers or refunds
     such differences in future periods.  This deferral results
     in an increase or decrease to gas costs in each fiscal year.
     The 1997 decrease was due primarily to lower firm sales as a
     result of the warmer weather, partially offset by higher
     per-unit gas costs.  The 1996 increase was primarily due to
     higher volumes of gas purchased as a result of the colder
     weather and full recovery of the prior year undercollection
     of gas costs.  Cost of goods sold increased $3.6 million in
     1997 compared to 1996, due to increased YESCo activity.

     Operation and maintenance expense increased $0.1 million in
     1997 compared to 1996 and decreased $0.6 million in 1996
     compared to 1995.  The 1997 increase was primarily due to
     increased expenses related to nonutility operations,
     partially offset by a decrease in Yankee Gas operation and
     maintenance expense. 

     Depreciation expense increased $0.9 million in 1997
     compared to 1996 and increased $0.1 million in 1996 from
     1995 levels. The 1997 increase was primarily due to
     additions in plant assets.

     Taxes other than income taxes increased $0.6 million in
     1997 compared to 1996 and increased $0.5 million in 1996
     compared to 1995.  The 1997 increase was primarily due
     to higher Connecticut unemployment taxes and municipal
     taxes, partially offset by lower gross earnings taxes
     resulting from lower revenues in 1997 compared to 1996.  The
     1996 increase was primarily due to higher gross earnings
     taxes which resulted from higher revenues in 1996 compared
     to 1995, and higher municipal taxes, partially offset by a
     reduction in Connecticut state unemployment taxes.  The
     1997 increase and 1996 decrease in Connecticut unemployment
     taxes was due to a decision by the Connecticut Supreme
     Court concerning the Company's 1992 work stoppage which
     allowed the Company to reverse, in fiscal 1996, an accrual
     for unemployment tax expense associated with claims paid to
     Yankee Gas bargaining unit employees in 1992.  

Other income decreased $5.4 million in 1997 compared to 1996 and
increased $2.7 million in 1996 compared to 1995.   The 1997
decrease was primarily due to the absence of earnings associated
with the Company's interest in Iroquois, while the 1996 increase
was primarily due to the gain on the sale of the Company's
interest in Iroquois.

Interest expense in 1997 decreased $2.1 million as compared to
1996 primarily due to lower levels of debt and lower interest
expense on Yankee Gas' deferred fuel balance.   Interest expense
in 1996 decreased $0.2 million as compared to 1995 primarily due
to lower debt, offset by higher interest on Yankee Gas' deferred
fuel balance.

Federal and state income taxes decreased $2.0 million in 1997
compared to 1996, and increased $5.2 million in 1996 compared to
1995.  The 1997 decrease was primarily due to lower taxable
income as a result of operating losses incurred by Yankee
Energy's nonutility subsidiaries.  The 1996 increase was
primarily due to increased earnings from operations over fiscal
1995.  Please refer to Note 2 to the Consolidated Financial
Statements for additional information concerning the components
of federal and state income taxes.


LIQUIDITY AND CAPITAL RESOURCES

Expenditures for plant, property and investments totaled $35.2
million in 1997 reflecting a $5.2 million increase from 1996, and
was funded primarily through cash generated from current
operations and short-term borrowings.

Cash flow (defined as net income adjusted for non-cash items such
as depreciation, deferred income taxes and the Company's non-cash
equity earnings from investments) represents the cash generated
from operations available for capital expenditures, dividends and
other needs.  Cash flows from operating activities decreased $7.8
million in fiscal 1997 compared to fiscal 1996 primarily due to
lower net income and changes in working capital, and decreased
$2.1 million in fiscal 1996 compared to fiscal 1995.

The seasonal nature of gas revenues, inventory purchases and
construction expenditures create a need for short-term borrowing
to supplement internally generated funds.  Yankee Gas has
arranged a $60 million revolving line of credit with a group of
four banks whereby funds may be borrowed on a short-term
revolving basis using either fixed or variable rate loans. 
Yankee Gas also has an additional $27 million of credit lines
available on an uncommitted basis.  Yankee Gas had $36.3 million
outstanding under its agreements at September 30, 1997 and $20.3
million outstanding at September 30, 1996.  In addition, Yankee
Energy had $2.7 million outstanding as of September 30, 1997 and
no amounts outstanding at September 30, 1996 on a $15 million
line of credit, which is available to fund the development of the
Company's unregulated businesses.  The weighted average interest
rates on short-term borrowings at September 30, 1997 and 1996
were 6.0 percent and 5.6 percent, respectively.

The long-term credit needs of Yankee Gas are being met by a first
mortgage bond indenture that provides for the issuance of bonds
from time to time as the need arises, subject to certain
restrictions.  At September 30, 1997, indenture requirements,
including the required coverage ratio, would allow for the
issuance of an additional $216 million of bonds at an assumed
interest rate of 7.4 percent.   

On February 1, 1996, the Company's system real estate subsidiary,
NorConn, secured a $6 million bank term loan to refinance two
existing real estate loans.  Under the agreement, the interest
rate is fixed at 6.24 percent for the seven-year term of the loan
and requires an annual $250,000 sinking fund payment.

On April 1, 1997, Yankee Gas redeemed all $30 million Series A
Tranche C First Mortgage Bonds which matured on that date. 
Yankee Gas used cash on hand and the issuance of a $30 million
principal amount of Series E First Mortgage Bonds on April 1,
1997, through a private placement.  The bonds were sold by the
initial purchaser to "qualified institutional buyers" as defined
in and pursuant to Rule 144A under the Securities Act of 1933. 
The bonds will mature April 1, 2012 and interest is payable at an
annual rate of 7.19 percent. 

On November 4, 1994, Yankee Energy filed a Form S-3 registration
statement with the Securities and Exchange Commission to issue up
to 1,200,000 shares of common stock under its proposed
Shareholder Investment Plan (Plan).  The Plan, which became
effective January 25, 1995, provides existing shareholders and
their family members the ability to acquire shares of common
stock through dividend reinvestment or voluntary cash purchases. 
The Plan provides the Company the option to use new shares of
common stock or market purchases.  The Company issued 52,212 new
shares which provided approximately $1.0 million of new equity
funding in fiscal 1996.  No shares were issued under the Plan
during fiscal 1997.  The new equity was used primarily to provide
capital contributions to the Company's nonregulated subsidiaries.

The Company's estimated capital expenditures for the fiscal years
1998 through 2002 are $194 million, including $55 million for
1998.  Approximately $54 million, including $15 million for 1998
is for capital expenditures in nonutility operations. The 1998
utility capital expenditures, including the installation of a new
customer information system, are expected to be financed by a
combination of internally generated funds and short-term
borrowings.  For Yankee Gas, long-term debt maturities and
sinking fund requirements will total $3.4 million in 1998.

The Company is currently implementing new systems and enhancing
existing systems to address year 2000 issues.  Management
believes that all system changes will be installed and tested
prior to the manifestation of year 2000 issues.  Currently, all
such charges associated with system enhancements have and will
continue be expensed and the costs of new systems will be
capitalized as appropriate.  Expenditures are expected to
continue through the next two fiscal years.

In addition, Yankee Gas expects to incur expenditures for coal
tar remediation efforts, which is more fully discussed in Note 9
to the Consolidated Financial Statements.  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 September 30,
1997.
          



MANAGEMENT REPORT

The consolidated financial statements of Yankee Energy System,
Inc. and subsidiaries and other sections of this Annual Report
were prepared by management, which is responsible for their
integrity and objectivity.  These financial statements, which
were audited by Arthur Andersen LLP, were prepared in accordance
with generally accepted accounting principles using estimates and
judgement, where required, and giving consideration to
materiality.

The Company maintains a system of internal controls over
financial reporting, which is designed to provide reasonable
assurance to the Company's management and Board of Directors
regarding the preparation of reliable published financial
statements.  The system contains self-monitoring mechanisms, and
actions are taken to correct deficiencies as they are identified.
Even an effective internal control system, no matter how well
designed, has inherent limitations, including the possibility of
the circumvention or overriding of controls, and such systems can
provide only reasonable assurance with respect to financial
statement preparation. Further, because of changes in conditions,
internal control system effectiveness may vary over time.

Through established programs, the Company regularly emphasizes to
its management employees their internal control responsibilities
and policies prohibiting conflicts of interest.  The Audit
Committee of the Board of Directors is composed entirely of
outside directors.  This Committee meets periodically with
management, the internal auditors and the independent auditors to
review the activities of each and to discuss audit matters,
financial reporting and the adequacy of internal controls.

Management believes that its system of internal accounting
controls and control environment provide reasonable assurance
that its assets are safeguarded from loss or unauthorized use and
that its financial records, which are the basis for the
preparation of all financial statements, are reliable.

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

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

We have audited the accompanying consolidated balance sheets and
consolidated statements of capitalization of Yankee Energy
System, Inc. (a Connecticut corporation) and subsidiaries (the
Company) as of September 30, 1997 and 1996, and the related
consolidated statements of income, common shareholders' equity
and cash flows, for each of the three years in the period ended
September 30, 1997.   These financial statements are the
responsibility of the Company's management.  Our responsibility
is to express an opinion on these financial statements based on
our audits.

We conducted our audits in accordance with generally accepted
auditing standards.  Those standards require that we plan and
perform the audits to obtain reasonable assurance about whether
the financial statements are free of material misstatement.  An
audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements.  An
audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating
the overall financial statement presentation.  We believe that
our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements referred to above
present fairly, in all material respects, the financial position
of Yankee Energy System, Inc. and subsidiaries as of September
30, 1997 and 1996 and the results of their operations and their
cash flows for each of the three years in the period ended
September 30, 1997, in conformity with generally accepted
accounting principles.

(a) Consistent with the terms of the Non-Employee Directors'
Restricted Stock Plan, incentive awards of 3,817 shares and 900
shares of restricted common stock were granted to Directors
during 1997 and 1996, respectively. Under the Long-term Incentive
Compensation Plan the market value of the restricted stock awards
has been recorded as unearned compensation and is shown as a
separate component of shareholders' equity.  The earned
compensation is charged to administrative and general expense as
shares become vested. Earned compensation was approximately
$66,000 for fiscal 1997 and $117,000 for fiscal 1996.

(b) On July 20, 1989, Yankee Energy became guarantor of a term
loan agreement between the Trustee for the Company's 401(k)
Employee Stock Ownership Plan (ESOP), and a commercial bank, in
the amount of $4,000,000.  The proceeds were used by the Trustee
exclusively to acquire outstanding shares of Yankee Energy common
stock pursuant to the terms of the Company's ESOP.  The final
maturity date of the agreement is July 1, 1999 with sinking fund
requirements of $400,000 for the fiscal year 1998 and $600,000
for the 1999 fiscal year.

(c) Long-term debt maturities and cash sinking fund requirements
on debt outstanding at September 30, 1997 for each of the fiscal
years 1998 through 2002 (excluding the ESOP sinking fund
requirement) are $3,617,000, $3,617,000, $4,567,000, $4,567,000,
and $4,567,000 respectively.

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


Note 1)   Summary of Significant Accounting Policies


The Company: Yankee Energy System, Inc. (YES or the Company)
headquartered in Meriden, Connecticut, is a diversified company
specializing in the distribution, conversion, and control of
energy to meet our customers' needs.  Our principal operating
subsidiary is Yankee Gas Services Company (Yankee Gas).  Yankee
Gas provides retail distribution of natural gas to a service area
of 68 cities and towns in Connecticut.  The Company's other
operating subsidiaries support our core business in natural gas,
or allow us to expand our growing businesses in energy-related
services.  Yankee Energy Services Company (YESCo) provides
comprehensive energy-related services through three principle
divisions.  YESCo Power designs, builds and maintains on-site
facilities for the production of thermal and/or electric power. 
YESCo Controls is in the business of engineering, installing, and
maintaining building control systems.  YESCo Services provides
comprehensive HVAC, boiler and refrigeration equipment services
and installation.  Other subsidiaries support the operations of
Yankee Gas and YESCo.  NorConn Properties, Inc. (NorConn) owns
selected system real estate, which it leases to Yankee Gas. 
Yankee Energy Financial Services (Yankee Financial) provides
energy equipment financing.  R.M. Services, Inc. (RMS) provides
receivables management services.

Principles of Consolidation:  The consolidated financial
statements of Yankee Energy include the accounts of all
subsidiaries.  Intercompany transactions have been eliminated in
consolidation.

Public Utility Regulation:  Yankee Gas is subject to regulation
for rates and other matters by the Connecticut Department of
Public Utility Control (DPUC) and follows accounting policies
prescribed by the DPUC.  The Company prepares its financial
statements in accordance with generally accepted accounting
principles which include 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, the Company 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.

Yankee Gas continues to be subject to cost-of-service-based rate
regulation by the DPUC.  Based upon current regulation and recent
regulatory decisions, the Company believes that its use of
regulatory accounting is appropriate and in accordance with the
provisions of FAS 71. 

Revenues:  Utility revenues are based on authorized rates applied
to each customer's use of gas.  Rates can be changed only through
a formal proceeding before the DPUC.  At the end of each
accounting period, a revenue estimate for the amount of gas
delivered but unbilled is accrued.

Depreciation:  The provision for utility depreciation is
calculated using the straight-line method based on estimated
remaining useful lives of depreciable utility plant in service,
adjusted for net salvage value and removal costs as approved by
the DPUC.  The depreciation rates for the several classes of
plant in service are equivalent to an overall composite rate of
3.3 percent in fiscal year 1997, 3.3 percent in fiscal year 1996
and 3.4 percent in fiscal year 1995.

Purchased Gas Adjustment Clause (PGA):  The DPUC-approved rates
include an adjustment clause under which gas costs above or below
base rate levels are charged or credited to customers.  As
prescribed by the DPUC, differences between the actual purchased
gas costs and the current cost recovery are deferred and
recovered or refunded over future periods. 

Equity Accounting:  The Company accounts for YESCo's investments
in energy production facilities using the equity method,
recording their proportionate share of earnings (losses) with
corresponding increases (decreases) in their investment. 
Distributions received reduce the carrying amount of these
investments. 

Income Taxes:  Differences exist between the periods in which
transactions affect income in the financial statements and the
periods in which they affect the determination of income subject
to tax.  The tax effect of such timing differences is accounted
for in accordance with the ratemaking treatment required by the
DPUC. 

Additionally, in accordance with FAS 71, as of September 30,
1997, the Company has a deferred tax liability and a
corresponding regulatory asset of approximately $11.0 million,
due to the effect of Statement of Financial Accounting Standards
No. 109, "Accounting for Income Taxes".                          

                               
Reclassifications:  Certain prior year amounts have been
reclassified to conform with current year classifications.

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.
          
Impairment of Long-Lived Assets: Yankee Energy adopted Statement
of Financial Accounting Standards No. 121, "Accounting for the
Impairment of Long-Lived Assets and for Long-Lived Assets to Be
Disposed  Of" (FAS 121), in fiscal 1997.  The implementation of
FAS 121 did not have a material adverse effect on the
consolidated financial statements of Yankee Energy.

Earnings per Share:  Earnings per share is computed based on the
weighted average number of common shares outstanding during each
year.  The Financial Accounting Standards Board issued Statement
of Financial Accounting Standards No. 128, "Earnings per Share"
(FAS 128).  FAS 128 specifies the computation, presentation and
disclosure requirements for basic and diluted earnings per share.
Yankee Energy will adopt FAS 128 in  fiscal 1998, and the Company
expects that this statement will have no material effect on
earnings per share.

Company and the statutory federal tax rate are as follows:

$1,939,000 and $1,751,000, respectively.
 
Future minimum rental payments, excluding associated costs
such as property taxes, state use taxes, insurance and
maintenance, under long-term noncancelable leases as of September
30, 1997, are approximately:

Note 4)  Postretirement Benefits

The Company has a noncontributory defined benefit retirement plan
covering employees of Yankee Gas, YESCo, and RMS.  Benefits are
based on years of service and employees' highest consecutive 60
months of compensation during the last 120 months of employment.
It is the Company's policy to fund annually an amount at least
equal to that which will satisfy the requirements of the Employee
Retirement Income Security Act and the Internal Revenue Code.  No
contributions were required or made in fiscal 1997 and fiscal
1996.  Pension assets are invested primarily in equity securities
and investment grade bonds.  

The components of net pension cost (credit) were:

In addition, in fiscal 1995 a cost of $2,734,000 was recognized
as a result of special termination benefits under the pension
plan and is included in the Company's 1995 Statement of Income
under the Operations category.   

Total pension cost resulted in income of $420,000 for the year
ended September 30, 1997, income of $13,000 for the year ended
September 30, 1996 and expense of $62,000 for the year ended
September 30, 1995.  Pension cost for 1997, 1996, and 1995
includes $85,000 in cost of living increases each year for
Northeast Utilities (NU) retirees who were previously employed in
the gas business operated by The Connecticut Light and Power
Company (CL&P), a subsidiary of NU.  These payments were agreed
to at the time of divestiture from NU.  

For calculating the plan's cost and year-end funded status, the
following assumptions were used:

During fiscal 1994, the Company adopted an Excess Benefit Plan
(EBP) that provides retirement benefits to executive officers and
other key management staff.  The EBP recognizes total
compensation and service that would otherwise be disregarded due
to Internal Revenue Code limitations on compensation in
determining benefits under the regular retirement plan.  The EBP
is not funded and benefits are paid when due from general
corporate assets.  

Note 5)  Postretirement Benefits Other Than Pensions

The Company provides certain health care and life insurance
benefits to its retired Yankee Gas, YESCo, and RMS employees. On
July 1, 1990, in accordance with terms of the divestiture, Yankee
Gas began compensating the NU System for a portion of the NU
System's liability for certain health care and life insurance
expenses of retirees or surviving spouses.  Yankee Gas and the NU
System will share costs in a defined manner until June 30, 2005. 
The cost of providing those benefits for NU retirees was
approximately $1,103,000 for the fiscal year ended September 30,
1997 and $1,104,000 and $1,070,000 for the comparable periods in
1996 and 1995, respectively. 

Yankee Gas has established two Internal Revenue Code Section
501(c)(9) Voluntary Employee Beneficiary Association (VEBA)
Trusts, one for union employees and one for non-union employees,
to fund its future liabilities for retiree health care and life
insurance benefits.  Contributions to the VEBA Trusts totaled
$1.728 million for both fiscal 1997 and fiscal 1996.  Assets of
the VEBA Trusts are invested primarily in equity securities and
investment grade bonds.  

The Company recognizes the cost of postretirement benefits over
the employment period that encompasses eligibility to receive
such benefits.

The components of net postretirement benefits costs were:

For Yankee Gas, the DPUC is allowing $1.728 million of associated
expenses to be recovered in rates and up to an additional $1.5
million annually which is being collected through the rate
settlement process further described under Note 9, as part of 
the DPUC re-opened Docket No. 92-02-19.

For calculating the plan's year-end funded status, as well as the
ensuing year's postretirement benefits costs, the following
assumptions were used:

      

                    
       
 Years Ended September 30,             1997           1996

                                                
Discount rate                           7.50%          7.75%
Expected long-term rate of return       9.00%          9.00%
Health care cost trend rate
     - First year                       8.00%          9.00%
     - Ultimate                         5.00%          5.00%



Trend rates are assumed to decrease one percent per year until
they reach the ultimate rate.  A one percent increase in the
weighted average trend rate assumption of health care claims
would result in a 16 percent increase in accumulated benefit
obligations and a 35 percent increase in net periodic
postretirement benefits costs.

The following table represents the postretirement benefit plan's
funded status reconciled to the consolidated balance sheets:

Note 6)  Stock-Based Compensation  

Yankee Energy established Long-term Incentive Compensation Plans,
in 1991 and 1996. Options on 65,600 shares of common stock were
granted under the 1991 plan and options on 63,800 shares of
common stock were granted under the 1996 plan. Under the terms
of the options granted, the exercise price of any option may not
be less than 100 percent of the fair market value of the common
stock on the date of grant. The stock options vest over a five
year period, with 20 percent becoming exercisable on each of the
first five anniversaries of the grant. All stock options expire
ten years from the date of grant.   

The Company accounts for stock options in accordance with
Accounting Principles Board Opinion No. 25, under which no
compensation costs have been recognized for stock option awards.
Had compensation costs of option awards been determined under a
fair value alternative method as stated in Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based
Compensation", the Company would have been required to value such
options and record such amount in the financial statements as
compensation expense.  Proforma net income and net income per
share for fiscal 1997 and fiscal 1996 would have been $16,919,000
and $1.62 and $21,881,000 and $2.10, respectively. Yankee Gas
arrived at the fair value of the stock grants at the date of the
grant by using the Black Scholes option pricing model with the
following weighted average assumptions: risk-free interest rate
of 5.375 percent, expected life of 5.0 years, expected volatility
of 18.0 percent and a dividend yield of 5.7 percent.


The following summarizes stock option transactions for the fiscal
years ended September 30, 1997 and 1996:

At September 30, 1997 and 1996 there were exercisable 38,136
options and 21,000 options, respectively, which have weighted
average exercise prices of $22.20 per share and $21.58 per share,
respectively.


Note 7)  Short-Term Debt
               
Yankee Gas has arranged a $60 million revolving line of credit
with a group of four banks whereby funds may be borrowed on a
short-term revolving basis using either fixed or variable rate
loans.  Yankee Gas also has an additional $27 million of credit
lines available on an uncommitted basis.  Yankee Gas had $36.3
million and $20.3 million outstanding under its agreements at
September 30, 1997 and 1996, respectively.  In addition, Yankee
Energy had $2.7 million outstanding at September 30, 1997 and no
amounts outstanding at September 30, 1996 on a $15 million line
of credit.  The weighted average interest rates on short-term
debt at September 30, 1997 and 1996 were 6.0 percent and 5.6
percent, respectively.   


Note 8)  Fair Value of Financial Instruments
               

The following methods and assumptions were used to estimate the
fair value of each of the following financial instruments:

Cash and Temporary Cash Investments:  The carrying amount
approximates fair value. 

First Mortgage Bonds:  The fair value of the Company's fixed rate
long-term debt is based upon borrowing rates currently available
to the Company.  Adjustable rate securities are assumed to have a
fair value equal to their carrying value.

The carrying amount of the Company's financial instruments and
the estimated fair value at September 30, 1997 and 1996 are as
follows:
                         




September 30,          1997                   1996

The fair values shown above have been reported to meet the
disclosure requirements of Statement of Financial Accounting
Standards No. 107, "Disclosures About Fair Values of Financial
Instruments," and do not purport to represent the amounts at
which those obligations would be settled.
 

Note 9)   Commitments and Contingencies
          
Construction Program:  The Company's estimated capital
expenditures for the fiscal years 1998 through 2002 are $194
million, including $55 million for fiscal 1998.  The Company
intends to use $140 million over this period, including $39
million for fiscal 1998, of these estimated expenditures to
maintain the reliability of the distribution system and in
projects that will generate or support gas sales and
transportation activities, including the installation of a new
customer information system.  The remaining $54 million,
including $15 million for fiscal 1998, is expected to be invested
in energy related projects and businesses.

Environmental Matters:  Fourteen sites containing coal tar became
the property of Yankee Gas at divestiture from Northeast
Utilities.  Contamination at these sites was caused by operations
of former manufactured gas plants at those locations.  Yankee Gas
has reported the results of its environmental studies to the
Connecticut Department of Environmental Protection (DEP).  The
DEP has not required that any remedial action be undertaken to
date.  However, of the fourteen, eight sites are presently listed
on the Connecticut Inventory of Hazardous Waste Sites.  Inclusion
of a site on this list indicates that remediation may be required
in the future.

Remediation has been conducted at three of these properties.  In
addition, Yankee Gas has developed a cost estimate for the
remaining sites based on various factors including the
probability of clean-up.  As a result of this effort, Yankee Gas
recorded a liability of $35 million in fiscal 1993 for future
environmental clean-up.  

Recovery of remediation costs has been specifically allowed by
Yankee Gas' 1992 rate case decision.  Presently, $325,000 is
allowed annually in rates.  If costs are expected to exceed $2.5
million on an annual basis, Yankee Gas is required to go to the
DPUC for review.  The DPUC has stated that "to the extent that
coal tar remediation expenses are prudently incurred, they should
be allowed as proper operating expenses."

Yankee Gas has received funds from certain of its insurance
carriers in settlement of certain claims for actual or potential
contamination at certain sites that may give rise to
environmental liabilities.  The terms of the aforementioned
settlements are subject to confidentiality provisions in
agreements between Yankee Gas and its insurance carriers.  The
proceeds are being reflected as reductions in the regulatory
asset associated with recoverable environmental clean-up costs,
as shown in the accompanying balance sheets.

Transition Costs-Order No. 636:  On April 8, 1992, the FERC
issued Order No. 636 on pipeline restructuring.  In essence, the
FERC found that absent the unbundling of traditional merchant
services, pipelines would not be able to achieve the FERC's long-
term goal of open access and provide transportation services that
are indifferent to the seller of the gas.  Order No. 636,
therefore, required all pipelines to implement restructuring of
their services by the winter of 1993-94.  The three major
pipeline systems serving Yankee Gas (Iroquois, Tennessee Gas
Pipeline Company and Algonquin Gas Transmission Company and its
affiliate, Texas Eastern Transmission Company), have all
restructured pursuant to the FERC directive.  Yankee Gas has
concurrently replaced the gas supply traditionally obtained from
the pipeline companies' merchant services with firm purchases
directly from producers and/or marketing companies.  Yankee Gas 
present annual capacity commitment is approximately $82.7
million.

Order No. 636 acknowledges that the restructuring of the
pipelines' traditional services will cause pipelines to incur
transition costs in several areas and provides mechanisms for the
pipelines to fully recover prudently incurred transition costs
attributable to the implementation of Order No. 636.  

On July 8, 1994, the DPUC issued a decision on the implementation
of FERC Order No. 636 by the Connecticut Local Distribution
Companies (LDCs).  The DPUC is allowing the LDCs to offset the
transition costs billed by pipelines under Order No. 636 with
recoveries from capacity release activity, refunds of deferred
gas costs for the 1992-93 period and all subsequent annual
deferred gas costs, gas supplier refunds, off-system sales margin
and interruptible margin earned in excess of target amounts. 

Through September 30, 1997, Yankee Gas has paid approximately
$19.5 million of transition costs and an additional $3.5 million
are anticipated. To date, Yankee Gas has collected $44.2 million
through a combination of credits received from gas supplier
refunds, deferred gas costs, excess interruptible margin, off-
system sales margin, and capacity release agreements.

On January 3, 1996, the DPUC issued a Final Decision in reopened
Docket No. 92-02-19.  The Docket allows for recovery of certain
deferred regulatory assets with the stipulation that Yankee Gas
would not increase its rates before October 1, 1998, except in
the event of certain circumstances which would adversely affect
Yankee Gas' financial condition.  Yankee Gas may apply a portion
of excess transition credits received from pipeline refunds,
interruptible excess margin, deferred gas costs, capacity release
activity, and off-system sales margin to certain regulatory
assets.  As of September 30, 1997, excess collections of
approximately $24.7 million were applied against the deferred
regulatory assets specified in the decision.

Firm Transportation:  On August 2, 1995, the DPUC issued a Final
Decision in Docket No. 94-11-12, DPUC Review of Connecticut Local
Distribution Companies' Cost of Service Study Methodologies.  The
docket was intended to investigate the issues surrounding the
development of firm transportation (FT) rates at the state level
in response to FERC Order No. 636.  The Decision provides
guidelines for the development of FT rates to be offered by the
State's three LDCs, one of which is Yankee Gas.  

On January 24, 1996, the DPUC issued a Final Decision on Docket
No. 92-02-19 Reopen I.  This decision enabled Yankee Gas to
implement FT rates and services as contemplated in the August 2,
1995 decision referenced above.  The Decision allows Yankee Gas
to offer a broad array of service options to commercial and
industrial FT customers.  Yankee Gas implemented these new FT
rates and services on April 1, 1996, and as of September 30, 1997
had approximately 1,460 customers under the new FT service.  A
switch by existing sales customers to transportation tariffs will
result in decreased revenues for Yankee Gas as the portion of
revenues representing gas costs will now be borne directly by
those customers. Yankee Gas, however, does not expect customer
conversions to transportation services to affect its net income
because the cost of gas has traditionally been a pass through
item with no income impact.  This Decision did not address Yankee
Gas' revenue requirement; Yankee Gas has maintained the existing
margin recovery and rates of return established in the last rate
case decision issued for Yankee Gas in 1992.

Rate Review:  On August 25, 1996, Yankee Gas filed an application
with the DPUC for a Financial and Operational Review (Review). 
This Review was required under Connecticut statute since Yankee
Gas had not undergone a rate proceeding within the last four
years.  Yankee Gas' last rate application was approved on August
26, 1992, and this Review was necessary to comply with the
statute.  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 PGA during the period November
1997 through March 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.

Gas Supply Hedging Activities: Yankee Gas has gas service
agreements with two customers to supply gas at fixed prices. 
Because Yankee Gas purchases gas on a variable price basis, it
has found it necessary to hedge gas prices with derivatives to
respond to customers' needs for fixed pricing.  Both agreements
are similar in structure in that Yankee Gas executed a commodity
swap contract with a commodity trading firm.  Under a master
commodity swap agreement, the price of a specified quantity of
gas is fixed over the term of the gas service agreement with the
customer.  In both cases, Yankee Gas is acting as an agent using
its credit to provide fixed pricing to its customers using a
commodity swap.  Yankee Gas' 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.  Also, the customers are accountable for all costs incurred
by Yankee Gas to execute and maintain the commodity swap
contract.

Of the two gas service hedging agreements currently in force,
only one is material relative to the significance of gas volumes
being hedged.  This agreement has a ten-year term and requires
Yankee Gas to supply approximately one BCF of gas per year, with
relatively low margin, at a fixed price beginning August 1, 1995.
The price is allowed to escalate by a predetermined rate every
year after the first year.  The commodity swap contract for this
hedging agreement was executed August 17, 1994.  Yankee Gas is
responsible for margin calls collateralizing the commodity swap
contract from August 17, 1994 through the term of the gas service
agreement.  Currently, Yankee Gas has a letter of credit in the
amount of $2.0 million issued to the commodity trading firm
collateralizing the commodity contract.
                                                    
Tax/Legal Issues:  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.  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.

In November 1995, a class action suit was filed against Yankee
Gas and the state's two other LDCs by the Connecticut Heating and
Cooling Contractors' Association, Inc., claiming the LDCs engaged
in unfair trade practices.  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.

The LDCs have asserted that such licenses are not required for
this work based on a statutory exemption enacted in 1965 and
amended in 1967.  However, in a separate proceeding, a
Connecticut Superior Court has upheld an administrative ruling
against the LDCs' position, which was affirmed on appeal.  In
1995, the Connecticut General Assembly enacted legislation that
established, on a going-forward basis, a separate procedure for
state certification of gas service employees.

While the ultimate results of the class action suit cannot be
determined, management does not expect that it will have a
material adverse effect on the Company's consolidated results of
operations or financial position.
