What is the SimplyFair12 tariff?
SimplyFair12 is a variant of our classic SimplyFair plan - based on the same core principle:
👉 100% renewable electricity, market-based pricing, full cost transparency, and fair contract terms.
The key difference:
👉 You receive a 12-month price guarantee for your energy price (ct/kWh).
This makes SimplyFair12 ideal for anyone who values planning security.
How is the price structured in the SimplyFair12 tariff?
1. Base fee
7 € Ostrom base fee per month
plus the fixed grid fees charged by your local grid operator
2. Energy price (ct/kWh)
Market-based energy price
12-month price guarantee: Your energy price remains fixed for the entire guarantee period and does not change.
🧮 How is billing handled in SimplyFair12?
Monthly deposit payments
You pay a monthly advance payment based on your expected annual consumption.
📊 Annual consumption statement (annual invoice)
Once per year, we compare your actual consumption with the advance payments (monthly deposit payments) you’ve made:
If you consumed less → you receive a refund
If you consumed more → an additional payment is due
The billing mechanism is the same as with SimplyFair - with the added benefit of a fixed energy price for 12 months.
🧮 How is the monthly deposit calculated?
Your monthly deposit is based on:
Your estimated yearly consumption
The SimplyFair12 energy price (with 12-month guarantee)
The monthly base fee (7 € + grid operator fee)
Formula:
(Estimated annual consumption × energy price) + (12 × base fee) ÷ 12
You can adjust your monthly deposit at any time in the app if your usage changes.
