           SJI Posts 18% Increase in Income from Continuing Operations
              Reports Record Earnings for a Fifth Consecutive Year

[Folsom, NJ] - Today, South Jersey Industries (NYSE: SJI) announced record
earnings from continuing operations for 2003 of $34.6 million, or $2.73 per
share, an increase of $29.4 million, or $2.43 per share from 2002 results. This
performance reflects an 18% increase in net income from continuing operations
and a 12% increase in earnings per share from continuing operations. Both
utility and non-utility business lines contributed to SJI's record performance.

"Exceptional earnings performance in 2003 marks our fifth consecutive year of
record earnings and our fifth year in a row of increasing SJI's dividend," said
SJI Chairman of the Board and CEO Charles Biscieglia. "Our performance clearly
indicates that our focused strategy of growing SJI in energy related markets has
been successful in achieving our goal of sustained, consistent earnings and
dividend growth. Our $0.08 annual dividend increase and the dividend policy of
3% to 6% annual growth announced in November of 2003, demonstrate our confidence
to SJI shareholders in our ability to continue the trend of record earnings
growth in the future."

Highlights For 2003 Include:
SJI Provides Strong Total Returns to Shareholders: Stock price appreciation,
combined with dividends paid in 2003, provided SJI shareholders with a total
return of 28% on their investment. For the 5-year period ending December 31,
2003, SJI's investors enjoyed a 14.5% annualized total return, which compares
very favorably to negative 2.5% and negative 0.6% returns from the S&P Utility
Index and S&P 500 Index, respectively.

Utility Business Produces Record Performance: South Jersey Gas' net income of
$26.6 million in 2003 was 15% higher than last year when it produced $23.2
million. Key contributing factors were:

o                 SJG added 8,188 customers to its customer base during 2003.
                  Customer growth of 2.8% continues to be well above the
                  national average of 1.8%. The growth rate is also the highest
                  of any gas utility in New Jersey. Dynamic economic development
                  in our service area, aided by an anticipated stream of
                  conversions from electricity and oil, the latter of which is
                  heavily driven by environmental issues, should help SJG
                  duplicate 2003's growth rate this year. These new customers
                  will add approximately $1.8 million to net income in 2004.
o                 Weather was 12.5% colder in 2003 than 2002. Significantly
                  colder weather in 2003 compared to the prior year, added $2.9
                  million to net income while the temperature adjustment clause
                  reduced gas costs to our customers by the same amount.
o                 Off-system sales activities added 9% to net income over last
                  year. Income from this business line grew by $550,000 in 2003
                  to $6.7 million. Higher profit margins per unit sold and
                  increased capacity release activity were the primary
                  contributors. To maximize the value of its pipeline and
                  storage assets, SJG actively markets these assets to third
                  parties when they are not needed by utility customers. Through
                  a sharing formula under which SJG splits proceeds of its
                  off-system sales with customers, SJG returned $11.0 million to
                  customers in 2003.
o                 Interest expense decreased by 8% in 2003. SJG realized lower
                  interest rates on both short-term and new long-term debt,
                  producing nearly $1 million in savings. We financed
                  redemptions of $75 million of higher rate debt with a
                  combination of equity and debt. The debt carries an average
                  rate of 4.98% and an average maturity of 17 years. Included in
                  the total redeemed was $35 million of SJG's 8.35% Preferred
                  Securities called in November 2003. These actions will provide
                  significantly greater future interest savings when in place
                  for a full year.

Non-Utility Income Contribution Jumps 28% Percent: Non-Utility operations
accounted for 23% of SJI's 2003 earnings, increasing to $7.9 million from $6.2
million in 2002. Reasons for the substantial performance hike include:

o                 Marina Energy delivered $1.1 million to SJI's bottom line.
                  This represented an $800,000 increase compared with 2002. The
                  major contributor to that improvement was the thermal energy
                  plant in Atlantic City, N.J. becoming fully operational in
                  July 2003. Plant operations have exceeded our expectations to
                  date.

                  We expect Marina's contribution in 2004 to double with a full
                  year of operation from the thermal plant and other projects
                  coming on-line.

o                 SJE's customer base increased by 23 percent. In 2003 South
                  Jersey Energy reaped the benefits of strong customer growth in
                  its retail gas marketing activities. SJE's customer count
                  increased to just over 93,400 customers from 76,200 at the end
                  of 2002. Commencement of electric marketing activities also
                  contributed positively to earnings. SJE was awarded a contract
                  to supply all electricity to many central and northern New
                  Jersey school districts through May 2005. SJE's net income
                  increased by almost $700,000 in 2003 to $3.2 million.

o                 Wholesale gas marketing profits grow by 19 percent. Higher
                  volumes of gas marketed, additional pipeline capacity and
                  storage assets, and favorable market conditions helped South
                  Jersey Resources Group grow net income from continuing
                  operations by almost $500,000, to $3 million, compared with
                  2002.

SJI Strengthens Balance Sheet: To maintain the financial flexibility necessary
to take advantage of the many growth opportunities present at SJI's utility and
non-utility operations, we strengthened our balance sheet during 2003. SJI
raised $36 million of equity through its dividend reinvestment program,
replacing $35 million of preferred securities. The result was a reduction of
SJI's debt-to-capitalization ratio from 65.3% at the end of 2002 to 58.8% at
year-end 2003. SJI's leverage typically peaks due to seasonal working capital
needs in the fourth quarter. SJI projects a debt-to-capitalization ratio of
approximately 50% during the first half of 2004.
