  3. Capability is the maximum power output of the system at any one point in time. A megawatt (MW) is a measure of power, like horsepower. A typical, conventional light bulb uses 100 watts of power. A megawatt is one million watts.

  4. Peak demand is the greatest amount of electric power required at any one point in time during the year.
    Return to text above.
     
  5. System demand is the amount of power used over the year, as measured in kilowatt hours (kWh). (A 100-watt bulb burning for 1 hour uses 100 watt hours or 0.1 kilowatt hours. Ten light bulbs burning for an hour would use 1 kWh. Your home electricity bill is measures in kilowatt hours.)
