Home Building FAQ
When building a new home there are many things
to consider when it comes to connecting electric service to your
new home. Questions are asked about the cost of service, and who
will cover those costs. Are there incentives for building a new
total electric home? Who
installs the underground cables? Who digs the trench? Here are some
common questions along with the answers from BHP Distribution Services...
Q. What
is the cost to obtain electric service for my new home?
A. For most new customers
we extend our electric facilities at no charge. Our practice is
to install new electric facilities that cost up to four (4) times
the Standard Annual Revenue. If the cost exceeds this amount,
then you will be required to make a refundable contribution prior
to the installation of any electric facilities.
Q. How can
I determine the Standard Annual Revenue and Line Extension Allowance
for my new home?
A. We have three (3) rate
options for new year-round residential customers:
|
Standard
Annual Revenue |
Line

Please visit with a BHP representative to determine

NOTE: These allowances can only be given
after the foundation has been started.

the cost of extending electric facilities to my home be determined?

to new residences:

Q. What
is a refundable contribution and how is it refunded?
A. When the cost estimate
exceeds the Line Extension Allowance for your new home you will
be required to make a refundable contribution equal to the difference.
You will be eligible for refunds up to the refundable contribution
paid for a period of four (4) years. Please visit with a BHP representative
for a detailed explanation of the refund procedure provided for
in the Application and Agreement for Electric Service Extension.
Refunds may result from additional extensions and the actual electric
revenue associated with your new home.
Q. Can
I request underground electric service?
A. Yes, overhead or underground
extensions are covered by the Line Extension Allowance for your
new home. You will, however, be required to provide the trench,
bedding, and back-fill for both primary and secondary lines according
to BHP and National Electric Safety Code Specifications.
Q. What
are the trench specifications?
A. The diagrams show the
depth specifications for both primary and secondary trenches.


Four inches of washed masonry sand will be placed
beneath, on both sides, and over the conductors before back-filling.
Use extreme caution while back-filling. Rocks on or near the wires
may cause cable failure.
Q. Can the
phone, gas, cable and television wires go in the same trench?
A. Yes, they can be laid directly
with the power cable in the trench, or placed as shown.

Q. What about
water, sewer and gas lines?
A. Gas lines can be placed
in the same trench as power cables. Gas, water and sewer lines must
maintain 12 inches minimum separation from power line trench specifications.
Q. Is it
okay to use a foundation excavation for part of my buried service
trench?
A. No, it is difficult to repair
services along a foundation wall. The service must be away from
the house in its own trench.
 
Q. Does it
matter if my buried service goes under a driveway or patio?
A. Every effort should be
made by the homeowner to locate the service in areas that will not
be paved. In the event this is not possible, a grey electrical 2"
Schedule 40 PVC conduit is to be laid in the trench beneath the
pavement so that the wire can be pulled out in case of cable failure.
This method speeds up repairs and eliminates the necessity to damage
the pavement to repair cable failures.

Q. Who
is responsible for the maintenance of the service line?
A. Black Hills Power maintains
both overhead and underground services up to the customer connection.
Customers are responsible for keeping tree branches clear of overhead
service lines.
Q. Where
is the customer connection?
A. For overhead services,
the connecting point is the customer owned weatherhead. For underground
services, the connecting point is the customer owned meter-can.
Shown is a diagram which indicates what the customer is required
to provide for their electric service. Black Hills Power provides
the meter as part of the monthly service charge.

Q. Is there
a preferred location for the meter?
A. Yes. Having the meter in
an easily accessible location for service access.
Normally the side or front of the house works best. It is important
not to locate the meter within a fenced area or inside a building
Q. How much
electrical capacity do I need in my new home?
A. The average new home should
have a 200 ampere service panel. If you plan a large home, you should
consider a 400 ampere service panel. Correct sizing should be done
with the advice of an engineer or your electrical contractor.
Q. Is
temporary construction power available?
A. Every attempt will be made
by Black Hills Power to provide temporary service for construction
power. Normally, temporary service for construction power is made
available for a service charge of $85 plus Tax. However, in some
cases, construction power is not available on site which could result
in additional costs to the customer.
