4. Saving energy and optimizing
electricity use
4.1. Your electricity contract
Your electricity contract tells the Asema system data needed to calculate an estimate of your
electricity bill. This data is used in drawing you the graphs that show what the use of each appliance
and your home as a whole actually costs at different points of time.
Asema E supports the following types of electricity contracts
1.
Fixed price
. A simple fixed price, you pay the same amount per each consumed kWh.
2.
Peak/off-peak
. A variable rate that changes twice per day at predefined hours. Peak hour price
(typically daytime rate) is higher than the off-peak price.
3.
Market rate (spot)
. A spot price changes dynamically depending on the market price at the
Nordic electricity exchange NordPool. Note that different utilities employ different formulas on
how the eventual price is charged. It may be charged per each hour or averaged over a period
of time (day, week or month).
For information on how to enter these settings into your Asema E, please read Section 6.5.3,
“Energy Contract”.
4.2. Price preferences
The price preferences tell the system what you actually consider a "cheap" or "expensive" electricity
price. The default setting is to analyze the daily rate at the NordPool exchange and set the limit
as a percentage of that price. You can however tweak those percentages as you wish or set an
absolute limit in your currency. To define your price preferences, please read Section 6.5.4, “Price
Limits”.
