Ampere (amps) A unit of electric current.
Battery Battery A device for generating an electric current.
Charge Electricity produced by a surplus (positive) or shortage (negative) of electrons in an object.


Circuit The complete path electricity follows from a source through a connection to an output device.


Current The amount of electric charge.


Conductor Conductor An object that permits an electric charge to flow easily.
Delivery Charge Delivery Charge A charge assessed to recover a TDU’s allowance to delivery electricity.
Deregulation The removal of pricing and competition barriers for natural gas and electricity providers in a given market, encouraging competition and customer choice.


Distribution The delivery of natural gas or electricity to your home or business through local gas pipelines or electrical lines.
Electricity Electric current used as a power source.


Energy The ability to do work. Two types of energy are kinetic and potential energy.


Energy source The primary source of providing power. The energy could be converted to electricity through chemical, mechanical, or other means. Common energy sources are coal, petroleum, gas, water, uranium, wind, sunlight, geothermal, etc.
Fixed rate plan A fixed rate plan ensures your supply rate is fixed over a period of time. This type of plan provides protection from market price volatility.


Fossil fuel A natural fuel (formed in the earth from plan or animal remains), such as petroleum, coal, and natural gas.


Fuel Fuel Any substance that can be consumed to produce energy.
Generator A machine that produces electric current.


Geothermal energy The heat energy from below the earth’s surface.


Grid The power network for electricity. This includes high-voltage transmission lines and substations.
Hydroelectricity Hydroelectricity A change of energy produced from running water into electricity.



Kilowatt (kW) A unit that measures electrical energy. 1,000 watts = 1 kW


Kilowatt Hour (kWh) The use of 1,000 watts of electricity in one full hour. 1 kWh = ten 100 watt bulbs all burning at the same time for one hour. 10 bulbs x 100 watts each x 1 hour = 1 kWh Kinetic energy- The energy of motion.



Lightning Lightning A visible flash of light produced by electrical discharge.



Mechanical energy The energy of motion uses to perform work


Meter Meter A device that monitors the amount of electricity passing through it. Power companies read meters to determine how much electricity each customer uses.


Megawatt A unit of power equal to one million watts.



Nuclear power The energy produced by splitting atoms in a nuclear reactor.



Potential energy Potential energy The capability of something to do work.


Power The force or energy used to do work (measured in watts).



Renewable energy A form of energy generated from a natural source, such as the sun, wind, tides, or waves.



Solar energy Energy produced by the sun.


Static electricity The collection of like charges.



Transformer Transformer A device that changes the voltage to AC electricity.



Variable Rate Variable Rate (Also known as a month to month rate) a rate that fluctuates based on changes in the commodity market.


Voltage The force that moves electric current through a conductor (measured in volts).


Volt Volt A unit that measures the force of an electric current.



Watt Watt A unit that measures electric power. 1kW= 1,000 watts. 1 Megawatt (MW) = 1,000,000 watts.


Wind Power Wind Power Wind power is electricity obtained by harnessing the energy of wind.
