What is a Channel?
- A channel
holds data of the same kind (such as kW, Power Factor, therms or degrees
- 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
following shows the selections that are available to you under Channels.
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.
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.
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
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.
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.
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.
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.
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
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/
