Channels
 

What is a Channel?

  • A channel holds data of the same kind (such as kW, Power Factor, therms or degrees Fahrenheit).

 

  • Energy Analysis provides information about the channel (Channel Detail), provides numeric interval data for each channel (Tab Detail), allows you to select which channel(s) you wish to display (Account/Channel Preferences) and provides graphs of the channels (Graphics).

 

  • The following shows the selections that are available to you under Channels.

 

 

 

Electric Accounts

 

 

  • Total, Peak, Time of Peak, and Average Demand are for the time period selected. Note how these values change if a day is selected as compared to a week.
  • Total lists the kWh for the indicated time period. It is calculated by adding all kW 15-minute time periods for the selected time and dividing by 4 to convert kW to kWh.

 

    • If there is more than one meter and you have selected the channels for each meter, you can see the usage for each meter. In the above example, meter A used 75,423.6 kWh, meter B used 63,771.1 kWh for a total (Summary channel) of 139,194.7 kWh for the week starting on Monday, Feb 23, 2009.

 

  • Peak and Time of Peak values are for the highest consumption for the time period selected. The Peak and Time of Peak values may occur at any time during the day and are NOT tied to on and off peak billing time periods. In the above example, the peak demand for meter A was 602.9 kW on February 23, 2009 at 9:15 a.m. for the week starting on Feb 23, 2009. The peak demand for both meters was 1,126.1 kW on February 25, 2009 at noon.
  • Average Demand is calculated by dividing the total kWh by the number of intervals in the selected time period. For the above example for meter A, 75,423.6 kWh is divided by 168 (24 hours times 7 days = 168) which equals an average demand of 448.9 kW for the week.

 

  • Interval Start Date and Interval End Date will show you the length of time that data is available for your account in Energy Analysis. Be sure to check the Interval End Date before doing a Bill Calculation to verify that the data that you need is available.

 

  • Data updates are done by manual processes. Data for most of the primary accounts is updated several times per month. Data for most general secondary accounts is updated monthly after the meter has been read.

 

  • Occasionally, there are problems with data collection and the data cannot be updated. Meters will retain data for several months, so if the data is not obtained one month, it may be available for the next month. Sometimes interval data is corrupted or was not obtained due to a meter change and the data cannot be provided.

 

Gas Accounts

 

 

 

  • Total, Peak, Time of Peak, and Average Demand are for gas days for the time period selected. Note how these values change if a day is selected as compared to a week.

 

  • Total lists the total therms for the gas days for the time period selected.

 

  • Peak and Time of Peak values are for the highest consumption for the gas day(s) for the time period selected.

 

  • Average Demand is calculated by dividing the total therms by the number of intervals in the selected time period. For the above example, 758 therms is divided by (24 hours) which equals an average demand of 31.58333 therms for the day.

 

  • Interval Start Date and Interval End Date indicate when data starts and stops.

 

  • Gas days begin and end at 9 p.m. central time.

 

  • Gas usage for accounts on gas transportation rates is automatically updated at about 5 p.m. each day.

 

  • Pool data for gas transportation accounts is automatically updated about midnight each day.

 

Electric and Gas Accounts

 

(E) in Channel will appear in front of some channels. This means that a start date field has a date in it. It occurs during set up for some accounts due to the effective date of the data.

 

(T) in Channel will appear in front of all channels. It means that the data has been translated from raw pulses to show energy values, such as kW, kVar, therms, etc.

 

Weather Data A channel with hourly temperature data has been added to each account and is automatically updated every day at about 11 a.m. The data is from the weather station data that We Energies has that is closest to the account. Peak and Time of Peak will list the highest temperature and the time of that temperature for the time period selected. Average Demand will list the average temperature for the selected time period. Total sums the temperatures listed for each interval and may not be useful.

 

Degree Day information is not available in Energy Analysis. However you may obtain degree day data for Wisconsin from the Wisconsin Department of Administration at the following web site: http://www.doa.state.wi.us/degreedays/
