What is Displayed and Why?

This display demonstrates our daily patterns of demand, namely, those morning and afternoon peaks driven primarily by heating of air and water in our homes.  When we get up in the morning, our home heat (or air conditioning) turns on and showers cause our hot water tanks to reheat.  Before dinner time, we come home, use the stove to cook our dinner and heat water to wash dishes and clothes.  These periods drive the two daily peaks in demand.  In the middle of the night and mid-day, our home energy systems are at a low point, demonstrated by dips in demand.  What do you make of the the patterns of demand shown for each substation?  Are they the same or different?

This display shows the current power consumed by all residences and business connected to each of the substations based on real-time data retrieved by Positive Energy from Puget Sound Energy. On these displays 100% capacity represents 29 MW of power demand. We want to avoid being in the RED zone at any substation, but particularly want to avoid both Winslow and Murden Cove being in the red simultaneously

If the needle is in the red for any substation, consider what action your home or business can take to reduce demand. During the peak times, as shown by the orange and red coloring on the clock, we can all lower our demand by putting off hot water usage (showers, clothes and dish washing) and clothes drying to a later time. We can also lower the thermostat 1-2 degrees and turn off unused lights.

Winter Months: During the winter months, our Island electrical energy use (“power” or Megawatts or MW) is highest due to heavy use of electric heaters, electric heat pumps and electric hot water heaters in the morning when we get up (6-9 am) and early evening when we come home (5-8 pm).  On particularly cold days, we may exceed the capacity of our three substations (Winslow, Murden Cove, Port Madison). To avoid the need for a costly additional substation, Puget Sound Energy has said that the sum of power provided Winslow plus Murden Cove substations should not exceed 58 MW, or roughly 29 MW each.

Spring, Summer, Fall Months: During these months, the display will highlight our overall consumption of energy by homes and businesses. The displays will be yearly, monthly, weekly and/or daily graphs of energy consumption as well as our progress towards energy savings.
