                  SJI Reports Record First Quarter 2005 Results
                   Income from Continuing Operations Jumps 10%
            Earnings per Share from Continuing Operations Rises 5.5%

[Folsom, NJ] --South Jersey Industries (NYSE: SJI) today reported record
earnings from continuing operations for the first quarter of 2005 of $26.9
million, a 10% increase over first quarter 2004 results of $24.5 million.
Earnings per share from continuing operations rose 5.5% to $1.92 as compared
with $1.82 for the prior year period. SJI's utility and non-utility operations
were both significant contributors to the performance improvement. "I am pleased
to report that SJI continues to deliver the strong performance that our
shareholders have come to expect," said SJI CEO Edward Graham. "Performance such
as that achieved in this record first quarter, combined with a number of actions
and initiatives that provide long-range benefits, position SJI to meet its goal
of producing 6-7% average long-term earnings per share growth," stated Graham.

Highlights For First Quarter 2005 Include:

Utility Business Income Contribution Increases 9%: Income at South Jersey Gas
rose $1.9 million to $22.6 million in the first quarter compared with $20.7
million for the same period in 2004. Key contributing factors were:

                                   Cover Page

o        SJG added 9,054 customers since March 2004. Our 3% customer growth rate
         is almost double the national average for gas utilities. Our
         expectation is that customer growth will remain at this pace for the
         remainder of 2005. Customer additions added $850,000 to income for the
         quarter.
o        Utility margins continue to benefit from rate case. SJG continued to
         benefit in the first quarter of 2005 from the July 2004 base rate case
         settlement. Restructured rates added $3.9 million to income for the
         quarter. The case was also responsible for a reduction in depreciation
         expense recorded by SJG that contributed $650,000 to net income for the
         period. While base rates increased as a result of the settlement,
         customer bills actually declined as certain cost recovery clauses were
         revised or eliminated to reflect current conditions.
o        Weather negatively impacted quarterly comparisons. Degree days that
         were 1.5% warmer than last year combined with less favorable use
         factors to reduce net income by $600,000. SJG has a weather
         normalization clause in its rates that protects both the company and
         its customers from the impacts of temperatures that vary significantly
         from normal.

Non-Utility Income Contribution Up 15%: Earnings from non-utility operations
increased to $4.3 million for the first quarter of 2005, up from $3.8 million in
the same quarter last year. Performance benefited from the following:

o        Commodity marketing results up 15%. Commodity marketing added $3.2
         million to SJI's bottom line during the first quarter of 2005, up from
         $2.8 million for the same period in 2004. The improved performance was
         due to higher margins produced by SJI's wholesale activities. That
         performance offset declines in retail commodity marketing that resulted
         from lower customer levels. Market conditions for gas prices made it

                                     SJI-2

         more economical for consumers to purchase gas from the utility, rather
         than marketers. Also, a reserve established for receivables from a
         customer that filed for Chapter 11 bankruptcy protection resulted in a
         $650,000 after-tax charge.

o        On-site energy production adds one new facility and signs two more.  In
         March 2005, commercial operations commenced at our landfill gas-fired
         electric generation facility in Atlantic County, NJ. We also recently
         signed contracts for two additional projects. In March 2005, we reached
         an agreement with the Borgata Casino, Hotel & Spa to provide for all of
         the energy needs for their previously announced 500,000 sq. ft.
         expansion project into 2026. We will expand our existing thermal energy
         facility to provide this service and expect this project to be
         operational by mid-2006. In April 2005, we entered into an agreement
         with the Pollution Control Financing Authority of Warren County (NJ) to
         develop and operate another landfill gas generation facility, similar
         to the project we just completed in Atlantic County. These contracts
         bring our total number of projects in development to three, including
         the energy facility being developed for Seneca Gaming's Niagara Falls
         casino. Marina currently has four operating projects. This business
         line delivered $640,000 to SJI's bottom line for the quarter.
         Contribution to net income declined by about $270,000 compared with the
         first quarter of 2004, primarily due to the non-recurrence of a State
         of New Jersey thermal energy credit received in the first quarter of
         2004.

o        Appliance Service contribution jumps 54%. Higher levels of appliance
         service contracts, price increases implemented in the fall of 2004, an
         expanding installation business, and productivity initiatives combined
         to boost income from our appliance service business to $420,000 for the
         quarter.

                                      SJI-3

Balance Sheet Improvement Continues: The strength of SJI's financial position,
as measured by the equity-to-total capitalization ratio, continued to improve
during the first quarter of 2005. The combination of strong earnings and new
equity, raised primarily during 2004, resulted in an equity ratio of 51% at
March 31, 2005, compared with 48% at the same point in 2004. Our target is to
maintain an average annual equity ratio of close to 50%. Management remains
committed to maintaining SJI's current low-to-moderate risk profile, even while
taking advantage of the many growth opportunities present for both SJI's utility
and non-utility operations. SJI is particularly focused on managing risk at our
non-utility operations. Examples include our plan to maintain fully hedged
positions in our commodity marketing businesses and ensuring project revenue
streams with long-term contracts.
