s <br />DUKE POWER COMPANY <br />UNDERGROUND DISTRIBUTION <br />INSTALLATION PLAN <br />AVAILABILITY <br />Normally, the Company's distribution and service facilities are installed above-ground on poles, towers, or other <br />fixtures. At the request of an owner (including builders, developers, contractors and customers), the Company will <br />install, own and maintain underground facilities under the terms and conditions of this Plan. <br />At the determination of the Company, in those areas where it is physically or economically infeasible, or impractical, <br />to place facilities above-ground due to structural or geographical congestion or load density, the Company may place <br />its facilities underground at its own option and expense. <br />DEFINITIONS <br />The term "overhead facilitie3 as used in this Plan, means an electrical distribution system having all components <br />installed above ground level. <br />The term "underground facilities as used in this Plan, means an electrical distribution system having some, or all, <br />components installed below ground level. <br />A "bulk feeder is a conductor system transporting the total electrical requirements of a large area from a substation <br />or other supply point into such an area, which may consist of several residential developments and other loads. A <br />"subfeedei' is a conductor system branching off of the bulk feeder to supply the requirements of a certain portion of <br />the area. The subfeeder may terminate in a given development, but the bulk feeder may, or may not, pass through the <br />development to serve adjacent areas. <br />A "primary voltage loop system" of conductors provides multiple supply routes to more than one transformer serving <br />the load requirements. A "primary voltage radial extension" of underground facilities consists of a single supply <br />route to a single transformer serving the load requirements. <br />"Secondary facilitie3' consist of equipment necessary to provide secondary voltage from the Company's transformer <br />to the owner's delivery point. "Primary facilitids consist of equipment, including transformation, to supply primary <br />voltage into the owner's property or development. <br />"Cost differene~' is the amount by which the estimated cost of underground facilities exceeds the estimated cost of <br />comparable overhead facilities, but not less than zero. <br />"Loss due to early retirement" is the original cost of the facilities involved, less accrued depreciation, less salvage, <br />plus the cost of removal. <br />SERVICE CATEGORIES <br />I. <br />RESIDENTIAL SERVICE <br />At the request of an owner, the Company will install, own and maintain underground facilities for service to single <br />residences, apartments, condominiums, and manufactured homes following these Plan provisions. Any charge to the <br />owner is for the cost difference of the necessary underground facilities requested and is non-refundable. The signed <br />agreement with the owner for underground service shall specify the payment arrangements. <br />A. Permanent Residences <br />Residences which are to be permanent customer locations on a residential rate schedule of the Company will be served <br />from underground facilities as shown below. <br />(1) New Service Installations Located in New <br />Developments <br />Service to new residences on lots averaging an acre <br />(43,560 sq. ft.), or less <br />Service to new residences on lots averaging more <br />than one acre <br />No Charge <br />No charge except for cost difference of new primary <br />facilities exceeding 300 feet per lot. <br />(Page 1 of 4) <br />
