Sec. 15.113  Power line carrier systems.



    Power line carrier systems, as defined in Sec. 15.3(t), are subject 

only to the following requirements:

    (a) A power utility operating a power line carrier system shall 

submit the details of all existing systems plus any proposed new systems 

or changes to existing systems to an industry-operated entity as set 

forth in Sec. 90.63(g) of this chapter. No notification to the FCC is 

required.

    (b) The operating parameters of a power line carrier system 

(particularly the frequency) shall be selected to achieve the highest 

practical degree of compatibility with authorized or licensed users of 

the radio spectrum. The signals from this operation shall be contained 

within the frequency band 9 kHz to 490 kHz. A power line carrier system 

shall operate on an unprotected, non-interference basis in accordance 

with Sec. 15.5 of this part. If harmful interference occurs, the 

electric power utility shall discontinue use or adjust its power line 

carrier operation, as required, to remedy the interference. Particular 

attention should be paid to the possibility of interference to Loran C 

operations at 100 kHz.

    (c) Power line carrier system apparatus shall be operated with the 

minimum power possible to accomplish the desired purpose. No equipment 

authorization is required.

    (d) The best engineering principles shall be used in the generation 

of radio frequency currents by power line carrier systems to guard 

against harmful interference to authorized radio users, particularly on 

the fundamental and harmonic frequencies.

    (e) Power line carrier system apparatus shall conform to such 

engineering standards as may be promulgated by the Commission. In 

addition, such systems should adhere to industry approved standards 

designed to enhance the use of power line carrier systems.

    (f) The provisions of this section apply only to systems operated by 

a power utility for general supervision of the power system and do not 

permit operation on electric lines which connect the distribution 

substation to the customer or house wiring. Such operation can be 

conducted under the other provisions of this part.
