From the power plant or wind turbines to the kitchen light bulb, is the path electricity takes as easy as going from point A to point B? Matt Lucas, a technician at Boone Electric Cooperative, explains the process is a little more complicated.
The electricity used in Missouri either starts in a power plant, wind farm or water dam. Missouri’s two power plants create electricity by burning coal, which heats water to steam. The steam turns turbines and magnets to create electricity. On wind farms the turbines are turned by the wind to produce electricity. Similarly, hydroelectric dams release water that flows through turbines.
Once the electricity is created it goes to a step-up substation. Missouri has one located in Springfield, which also serves parts of Iowa, Nebraska, Oklahoma and Kansas. Here, transformers take the energy, or voltage, and sends it long distances through high voltage transmitters, which can handle the 500,000 volts. Large insulators are used, preventing energy from going to the ground or structure. “They have helicopters and people hanging from ropes maintaining these [high voltage insulters],” said Lucas.
Energy is lost as electricity flows through the large high voltage poles on their way to a transmission sub-station. At the station, lines from the large poles drop into the transformers where voltage is reduced to 34,500 to 115,000 volts, making it suitable for local use. The voltage is sent out on local use poles. This process will repeat at another transmission sub-station where energy will be reduced to 7,200 to 13,200 volts.
The next step is residential electric delivery. The electricity reaches a transformer on a pole, ground box, or side of the house. At this local consumer level the meter measures kilowatts per hour used by the house.
“We have to pay for amount of energy we will possibly use,” explains Lucas. Once a year the electric company will project and provide the power plant with their ‘power potential,’ the amount of energy the electric company may possible need. The power plants run non stop and produce the amount of energy outlined in the contract. The electric company is being charged for the electricity that is being produced and on the lines, even if it the electricity not being used.
Missouri currently has three commercial wind farms, all located in Northwest part of the state. Bluegrass Ridge Wind Farm, located in Gentry County, has 27 turbines on 10,000 acres. On average, the farm produces 2.1 megawatts per turbine. Three of those turbines could produce enough energy for 45,000 houses or half the size of Columbia.
The Cow Branch Wind Energy Project, in Atchison County, has 24 turbines covering 7,000 acres with 35 landowners. Each landowner receives supplemental cash, equaling $5,000 per turbine on their property.
Nodaway County’s Conception Wind Energy Project, financed by John Deere Wind Energy, consists of 24 turbines on 7,000 acre with 28 landowners.
There is currently an energy scare among the electric companies. Demand for electricity has increased but sources for energy hasn’t. Electric providers are trying to get consumers to cut back and be more conservative with electric use since there is an energy scare in the state. While they are in the business to make money, they are also wary of the possible energy threat.
“We’ll have to cut back or create new energy because usage is going through the roof,” said Lucas who compared the current energy situation to balancing a checkbook. We either need cut back on our spending (usage) or find a new source of income (energy). In preparation for the possible future energy shortage in Missouri a new cal-burning power plant is being planned for Southern Missouri. A coal plant is being discussed because we have the technology for that. Right now, wind energy is a good idea, according to Lucas, but the technology to lower prices has yet to occur. “When technology catches up, prices drop.” Until that technology is able to catch up with the energy demand in Missouri, coal-burning plants will continue to produce a majority of our electricity.
