                           ENERGY MANAGEMENT SERVICES

- -  Frost & Sullivan's estimates are focused on the primary competitors of the
   ESCOs

- -  The market estimates do NOT include:

   -  Commodity sales (natural gas, electricity, etc.)
   -  Non-energy facility management
   -  Utility-sponsored demand side management
   -  Third-party project financing
   -  Energy management software
   -  Sales of energy management efficiency equipment where the primary reason
      for purchase was not energy management

- -  Frost & Sullivan's estimates assume that equipment revenues will grow
   slightly higher than services due to anticipated technology innovations that
   will drive the retrofit market

- -  Projections for 2006-2010 based on a 9.1 percent CAGR and a 33/67 percent
   total revenue split between equipment and services and consulting,
   respectively

ANALYSIS  MARKET SIZE    SEMPRA'S TARGET MARKET
- --------------------------------------------------------------------------------

A NUMBER OF ASSUMPTIONS WERE MADE TO CONVERT THE TOTAL MARKET TO SEMPRA'S TARGET
MARKET.

     Assumptions

- -    Focus on attractive regions
- --------------------------------------------------------------------------------
     -    Regions with a significant contestable power market

     -    Regions likely to have attractive future generation opportunities
          (capacity needs, spark spreads, etc.)

- -    Exclude segments which are difficult to penetrate (petroleum refining,
     primary metals, commodity chemicals, small commercial)

     -    Exclusions of 35 percent for Industrial and 34 percent for Commercial
- --------------------------------------------------------------------------------
- -    Focus non-commodity services in the same states/segments as commodity
     supply

- -    Exclude equipment from non-commodity market

Note: During our corporate strategy discussions, it was concluded that:

      -  Generation is required to support the C&I market

      -  Generation will need to be able to 'stand alone' in terms of economic
         returns

      As a result marketing areas selected are judged to be likely
      attractive generation locations

ANALYSIS Gross Margins
- --------------------------------------------------------------------------------
WHEN THE DIFFERENT MARGINS ARE APPLIED ACROSS THE SEGMENTS IT IS CLEAR THAT,
WHILE THE COMMODITY DOMINATES REVENUE, A VERY LARGE PROPORTION OF THE GROSS
MARGINS WILL BE REALIZED FROM NON COMMODITY OFFERINGS.

ANALYSIS  Segment Costs
- --------------------------------------------------------------------------------

USING SOME SIMPLIFYING ASSUMPTIONS, WE ESTIMATED OPERATING COSTS FOR EACH OF

     9 percent of revenues by 2010

[ILLEGIBLE]

- -    Administration, sales, and support staff expensed outside of gross margin
     assumption

     - Initially 50 staff growing to 140 by 2010
