How we send the power to you

At our substations, through 69kv transmission lines we take delivery of our power from Southwest Power Administration as well as City Utilities of Springfield. In these substations we have equipment sophisticated enough to step down the 69kv voltage to a very minimal voltage, which can be conveniently connected to measuring and recording instruments. This type of equipment allows us to see anything that may happen on our line throughout the system. We also have 69kv breakers which protect these transmission lines from any possible faults such as: lightning, trees, or ice. Through large transformers inside the substation we reduce the voltage from 69kv to 12.4kv. At this point voltage is directed throughout the city to even smaller transformers near your home or business. Finally, these transformers step down the voltage to a safe and usable voltage to bring indoors. We call this lower, usable, voltage secondary voltage. This secondary voltage can be supplied at different amounts depending on a customers needs.

Energy Saving Tips for Seasonal Weather


Energy Saving Tips Around the Home

    Doors and Windows

  • Check the seals around doors and windows.  Air leaks can cause your electric bill to be higher.  It also makes your heater and air conditioner work hard which can shorten their lifespan.
  • In hot weather, shut curtains and shades to keep out natural solar heat.  In cold weather, open them during the day.

    In the Kitchen

         The Dishwasher

  • Run the dishwasher only when it is full.
  • In the winter run the dishwasher while at home.

        Oven and Stove

  • When using the oven, open it as little as possible.  Reheat foods in the microwave.
  • Use glass cookware in the oven.  Glass retains heat more than metal pans, which cooks your food faster.
  • Don't line oven racks with foil.  This will prevent heat from circulating around the food.
  • When using the stop top don't use small pots on big burners.  When boiling water, put a lid on the pot.

        The Refrigerator

  • Check seals of the refrigerator with "the dollar bill" test.  Take a dollar bill and shut it in the door with about half of it sticking out.  Pull the bill out while the door is closed.  If the bill pulls out easily, you should replace the seal.
  • Check the temperature setting of your freezer.  If ice cream is too hard to scoop out, then your setting is too low. 

    The Laundry Room

  • According to the Department of Energy, almost 85% of electricity for washing clothes goes towards heating water.  Wash in cold water whenever possible. 
  • Wash full loads.  If you have to wash a load that isn't full, make sure the water setting matches your load size. 
  • When possible, run the washer and dryer at night.  These units generate heat as they run, making your air conditioner run more in the summer. 

    Light Bulbs and Electronics

  • Use fluorescent bulbs instead of regular incandescent bulbs.  They use 75% less electricity and last ten times longer.
  • Turn off all TVs, stereos, computers and all other appliances when not in use.
  • Turn lights off when leaving a room.
  • Keep the thermostat at 78º in the summer and 68º in the winter.
  • Don't leave fully charged devices plugged in.
