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 the Calvert Cliffs plant to the 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.

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 41,919 conductor miles of distribution lines, including 19,985 conductor miles of overhead lines and 21,934 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 194 company owned locations with 447 installed transformers. Total transformer capacity is approximately 27,605 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:
