The Johnson City Power Board is an electric power distributor located in Johnson City, Tennessee, serving over 75,000 customers in 5 counties.

JCPB operates and maintains over 2000 miles of 13KV distribution lines and over 120 miles of 69KV transmission. The peak system load on JCPB’s system is 550 MW. JCPB has 30 distribution substations with over 100 distribution feeders.

JCPB purchases power from the Tennessee Valley Authority. In March 2010, TVA converted their billing structure to include demand power charges for each distributor. Therefore JCPB decided to implement a conservation voltage reduction plan during peak loading times in order to save on peak demand charges.
