Our pricing model sets the amount of your monthly deposit and is based, in addition to your electricity usage in kWh, on these components:
Yearly Consumption kWh
The yearly consumption in kWh is how much electricity you use per year.
Working Price in ct/kWh
The Working Price is calculated as cents per kilowatt/hour. At Ostrom, this is the energy at cost price, with no markups.
Grid Fees
The Grid Fees comprise all taxes and levies that are needed to get electricity from a power plant to your home.
Basic Fee
The Basic Fee is our flat 6€ per month fee at Ostrom. Unlike other providers, we only have this flat fee and do not earn more on your Unit Price.
Example
For example, a unit price of 30 ct/kWh at a yearly consumption rate of 1200 kWh, grid fees of 4€, plus the basic fee of 6€ would calculate a monthly cost of:
1200 kWh / 12 months = 100 kWh/month
100 kWh x 30 ct/kWh = 30€
30€ + 4€ grid fees + 6€ flat fee= 40€
→ 40€ final monthly price (example)
