Powerline Questions

New Construction/Line Extensions

If you need a line extension to provide electric service to a new site, you must schedule an on-site appointment with our Line Superintendent, Kent Larson or Staking Engineer Wade Bollinger. The following information will be required:

  1. Name and contact information.

  2. Proposed location of your metering package.

  3. The location of any buildings, sheds, wells, septic systems, sprinkler systems, paved areas, and so forth (existing and proposed), which may interfere with the routing of the new electric cable. Whenever practical, new service wires will be overhead.

  4. Anticipated date the new service will be required.

No line extension or new service will be staked or built unless a viable power load exists. Examples: a functioning well, footings or improvements to property to show that a new electrical service will be used. Service will be placed next to or nearby the power load.


In addition, applicants for service requiring a line extension in excess of one thousand (1,000) feet shall be required to make a contribution in aid to construction for each foot in excess of one thousand (1,000) fee in an amount equal to:

a)   $1.50 per foot for a single phase line extension up to 1,000 ft.

b)   Four dollars ($4.00) per foot for a single-phase line extension over 1,000 ft.

c)   Ten Dollars ($10.00) per foot for multi-phase line extension.

d)   Ten Dollars ($10.00) per foot for an irrigation line extension.

1. Consumers making application for an irrigation account shall be required to sign a five (5) year service contract.

Meter Testing for Accuracy

Electric watt-hour meters are highly accurate measuring devices. Moreau-Grand Electric Cooperative follows a routine plan of testing meters for accuracy. Each meter on our system is tested within an eight-year period. Records of meter tests are kept for all meters currently in use.

Occasionally, an inaccurate meter is found. Often, its inaccuracy is due to meter tampering.

Meter tampering is a crime and will not be tolerated!

Some people are shocked by what they find when they dig in their yards. New trees, shrubs, fence posts, or mail boxes all require some digging a hole from a foot to several feet deep. The problem is that you don’t really know
what you are going to dig in to. It may only be a few earthworms or the ball point pen you lost a few years ago. On the other hand, it could be a buried utility line. So, call South Dakota One Call at (800) 781-7474 or Moreau-Grand at (800) 952-3158 or 865-3511 before you start to dig. They’ll help you avoid the shocks. Many power interruptions are caused by trees, either by limbs rubbing on wires or the wires being torn down by falling branches or trees. When this problem occurs on a primary line, it can cause a service interruption across a wide area. Fallen wires can still be energized and should never be touched. Warn others to stay clear and call our office immediately, should you discover this situation.

Proper Tree Selection and Planting

Where to plant:

  1. Plant the right tree in the right place
    Determine location of overhead and underground utility lines. Remember, trees are more than just what you see overhead. Often, the root area becomes larger than the branch spread above ground.

    Since many different types of utility services are now buried, please call South Dakota One Call before you begin to dig. The location of these facilities should directly correlate to your choices of tree type and site selection. Do not assume that utility lines and facilities are buried deeper than you plan to dig. In some cases, underground facilities are very close to the surface.
  2. Determine type of tree. Consider its height at full maturity and the root area it will require. Remember, trees grow in width as well as height.

    Trees that will reach 25 to 50 feet high at maturity should not be planted within 30 feet of overhead electric lines. Trees that will reach 50 feet or more at maturity should not be planted within 50 feet of overhead electric lines. Children or adults climbing in trees can receive severe or fatal injuries if they come in contact with the overhead wires.

    Low-growing trees that will not grow taller than 20 feet may be planted closer to overhead power lines. However, Moreau-Grand Electric Cooperative asks that you do not plant trees or shrubs in close proximity to our poles or any pad mount transformer or junction box, as the tree will limit access to equipment by our crews. Please maintain a buffer zone of about 15 feet from all utility lines and equipment.

Consult your local nursery or the County Extension office for information to help you select trees that will be appropriate for your property.

Tree Trimming and Removal

Occasionally, large and established trees may require trimming, or removal, to avoid hazardous conditions or service interruption problems. We appreciate your cooperation in allowing us to continue to provide safe, efficient and reliable service to you and your neighbors.
