We Energies continually produces electricity to meet our customer's needs. Electricity is
produced at power plants, which typically use fuel to produce heat to boil
water and create
steam to spin a large fan called a turbine. The turbine rotates a large
magnet to create an
electrical charge that is then delivered through a network of transmission
facilities to our customers. We Energies uses several different fuel sources to produce

- Coal-fueled plants are a lower-cost generation, used around the clock to meet
customer demand. The coal is transported to the plants by rail or ship. While coal is
plentiful and transportation dependable, new technology is continually developed to
improve the efficiency, cleanliness and safety of this type of generation.
Natural-gas-fueled plants are used only at times of the day when customer demand
is greatest, because it is a more costly fuel. Natural gas is transported to plants by
Nuclear plants run almost continuously to meet customer demand, because they have
no emissions and low fuel costs. They are fueled with uranium that releases heat when
split into microscopic pieces (nuclear fission).
Wind turbines use large propeller-like rotors to spin turbines. Steady winds of about 12
per hour are needed to economically generate electricity from wind power.
Hydroelectric plants use the force of falling water to spin the turbines.
Bio-mass plants are fueled by organic materials such as crop residue, construction
un-recyclable paper to produce the heat to drive the steam turbines. Other
bio-mass plants burn methane from landfills or farm waste.
Purchased energy is obtained from other power producers and then delivered through the
transmission and distribution facilities to help meet customer demand. Purchased power is
used when it is less costly than We Energies generation or when customer demand exceeds
We Energies generating capacity.
Step-up transformers increase the voltage so electricity can be delivered long distances
on transmission lines.
Transmission lines carry the high-voltage electricity from power plants to the customer.
The transmission system in Michigan 's Upper Peninsula, eastern Wisconsin and
Illinois is owned and operated by the American Transmission Company.
Step-down transformers are located at substations. They decrease the voltage to make
it acceptable for customer use.
Poles carry the distribution wires that lead from substations to homes and businesses. The
We Energies distribution system has more than 40,000 miles of power lines, 679,000 poles,
and 265,000 transformers.
Transformers are located on some poles to further reduce voltage.
We Energies provides electricity to approximately 95,000 small and medium size
that receive power through a wire called a service drop much like
through the service panel and is branched off to
a facility. Some equipment may require different voltages, or
We Energies provides as needed.
We Energies has approximately 1.3 million residential customers that receive power to their
homes through a service drop, which enters through an electric meter.

Some homes have equipment to generate some or all of their own electricity, such
panels and wind turbines. Customer choosing to do this can be
connected to the We
Energies distribution system.
Pad transformers are located on the ground and function the same as pole-mounted
transformers, which reduce the voltage for use in homes and businesses.
Underground cables are similar to overhead wires, which delivery electricity from
to homes and businesses.
Large businesses, such as factories, paper mills, or foundaries, have special power
