           In addition, Constellation Energy Group, Inc. owns 100% of the stock
of 46 shell, inactive subsidiaries incorporated in each state except Maryland,
Ohio, Pennsylvania and Hawaii under the name Constellation Energy Group, Inc.

     2.    A brief description of the properties of claimant and each of its
subsidiary public utility companies used for the generation, transmission, and
distribution of electric energy for sale, or for the production, transmission,
and distribution of natural or manufactured gas, indicating the location of
principal generating plants, transmission lines, producing fields, gas
manufacturing plants, and electric and gas distribution facilities, including
all such properties which are outside the State in which claimant and its
subsidiaries are organized and all transmission or pipelines which deliver or
receive electric energy or gas at the borders of such State.

Electric

     Baltimore Gas and Electric Company (BGE), a subsidiary public utility of
claimant, owns 1,268 miles of transmission consisting of 215 circuit miles of
500 kV lines; 320 circuit miles of 230 kV lines; 54 circuit miles of 138 kV
lines, and 679 circuit miles of 115kV lines, located throughout Central
Maryland.

     BGE's 500 kV transmission consists of two circuits which connect to the
Calvert Cliffs plant to BGE load center as well as five circuits which
interconnect with and are part of the Pennsylvania - New Jersey - Maryland (PJM)
500 kV system. These circuits form a partial 500 kV transmission ring around the
Baltimore metropolitan area. Additionally, the Calvert Cliffs-Chalk Point,
Calvert Cliffs-Waugh Chapel, and Waugh Chapel-High Ridge circuits are part of
the "500 kV Loop", a full 500 kV transmission ring around the Washington
metropolitan area with several transformation points to 230 kV.

                                       19



        BGE's 230 kV transmission connects at two locations via transformation
with the 500 kV system and at ten locations via transformation with our 115 kV
network, throughout Central Maryland.

        BGE owns approximately 40,715 conductor miles of distribution lines,
including 19,915 conductor miles of overhead lines and 20,800 conductor miles of
underground lines, throughout Central Maryland. These figures only include
circuits operating at 34.5, 13.8 and 4 kV.

        BGE's transmission and distribution systems are comprised of 211 company
owned locations with 427 installed transformers. Total transformer capacity is
approximately 28,252 MVA throughout Central Maryland. These figures do not
include BGE-owned facilities located on customer premises. In addition,
generator step-up and other customer-owned transformers are not included in
these figures.

        BGE's transmission system is connected to other systems via the
following transmission tie lines:

            (1) two connections at the Maryland-Pennsylvania state line near
Delta, PA with PECO Energy Company transmission lines.

            (2) four connections with the Pennsylvania Power and Light Co. at
the Maryland-Pennsylvania state line, three connections near Graceton, Md., and
one near Norrisville, Md.

            (3) one connection with the Metropolitan Edison Co. at the Maryland-
Pennsylvania state line near Twin Farms, Md.

            (4) six active connections with Potomac Electric Power Company, two
near Burtonsville, Md., two near Bowie, Md., one near Mt Airy, Md., and one near
Eagle Harbor, Md.

Gas

        BGE owns 9 gate stations located at various points in its service
territory where natural gas is received from suppliers. Natural gas is delivered
to customers through approximately 6,120 miles of mains and 6,920 miles of

        .     a liquefied natural gas facility for the liquefaction and storage
              of natural gas with a total storage capacity of 1,092,977 Dth and
              a daily capacity of 311,500 Dth located at Spring Gardens, MD, and

        .     a propane air facility with a total storage capacity equivalent to
              554,200 Dth and a daily capacity of 85,000 Dth located at Notch
              Cliff, MD.

        BGE's current pipeline firm transportation entitlements to serve our
firm loads are 284,053 Dth per day during the winter period and 259,053 Dth
during the summer period.

        BGE has 235,080 Dth per day of pipeline natural gas storage
