The charge for all overhead extensions shall be the total cost of installation as defined in §
263-40, less the average depreciated embedded cost. (See §
263-39D.)
In the event an extension is partially or completely supported
on structures used for supporting transmission circuits or in the
event the extension is built to serve both single-phase customers
and three-phase customers, the Utility will compute and apportion
among the customers served the extension contribution requirements
and contribution refund rights in a fair and equitable manner consistent
with the pertinent facts and will retain in its files a memorandum
of such computation and apportionment. The contribution requirement
of the single-phase customers shall not be greater than would have
been the case if an extension (complying with present engineering
standards) had been constructed to only serve single-phase customers.
The Utility will extend Utility-standard underground service
to all classes of retail customers requesting new service in all areas
served by the Utility.
The charge for all underground extensions shall be the total cost of the installation as defined in §
263-40, less the average depreciated embedded cost as defined in §
263-39D.
In accepting an application for underground electric service
under this schedule, the Utility does not undertake to avoid the construction
of overhead lines in the neighborhood which may be necessary to serve
customers who demand and have the right to receive service from overhead
lines. However, in order to avoid duplication of facilities, applicants
for electric service whose premises can be served from an underground
distribution system that has previously been installed adjacent to
the applicant's premises shall be required to be served by an
underground lateral from such system and shall pay the contributions
and charges required in these extension rules.
