Finnish energy companies have started selling on “Hybrid plans” as fixed price c/kWh plus consumption based flexible part c/kWh.
Monthly flex add-on price is calculated as:
(A-B) / E = c/kWh
A = hourly energy consumption (kWh) x hourly market price (c/kWh)
B = monthly energy consumption (kWh) x monthly average market price (c/kWh)
E = monthly energy consumption (kWh)
The flex part is only calculated at the end of month that will be put on the invoice as a separate line. So there will be one line for each:
- Fixed price consumption
- Flex price consumption
- Energy tax
- VAT
- Monthly service fee
Should be noted the for the current active month the values are always estimates, as the flex price for the invoice is only known at the end of month. Meaning that the actual price for monthly energy can only be accurate for the past month. However having the estimates available helps improve the steering of consumption towards cheeper hours.
I would like to have for
Energy DAP device:
- Value for the current rolling (num days of month) average price
Avg. price this month.- This is only a estimate during the month and only valid at the
- Value for the monthly average price of the prev month
Avg. price prev. month.
