)NOTICE OF
)MODIFIED PROCEDURE
)ORDER NO.34467
On September 13,2019,Rocky Mountain Power ("Company")applied for authority to
revise paragraph 1 of Electric Service Regulation No.6 -Company's Installation-to include a
new option for customers to receive single-phase 240/480 volt secondary service.The Company
asked the Commission to review its Application under Modified Procedure.
The Commission now issues this Notice of Application and Notice of Modified
Procedure establishing a public comment period and Company reply deadline.
NOTICE OF APPLICATION
YOU ARE HEREBY NOTIFIED the Company estimates 40%of its distribution lines
are single phase 120/240 volt service.The lack of a three-phase service can make it difficult for
customers to operate equipment with large electric motors-such as irrigation pumps,sewage-lift
stations,and mine-ventilation equipment-because that equipment typically runs on three-phase
power.
YOU ARE FURTHER NOTIFIED where capacity is available on existing single-phase
120/240 volt lines,a three-phase supply can be derived using a variable frequency drive or rotary
phase converter to provide 240/480 volt service.
YOU ARE FURTHER NOTIFIED on average 480 volt converters and motors are 10%
to 25%less expensive to operate than 240 volt converters.
YOU ARE FURTHER NOTIFIED accommodating single-phase 240/480 volt service
will have little impact on the Company's construction standards,practices,and inventory
requirements,but adding three-phase service is cost prohibitive.2
Electric motors over 7.5 horsepower have limited commercial availability on single-phase service.
2 The Company estimates that building or extending three-phase primary lines would cost $60,000 to $150,000 per mile.
