# Tariffs

The **Tariffs** tab shows the electricity tariff details assigned to this household. Tariff information is used by the platform's recommendation engine to calculate cost-based insights and personalise energy-saving recommendations — for example, suggesting that a user shift consumption to off-peak hours.

## Tariff Chart

The main area displays a **bar chart** that visualises the applicable electricity rate for every hour of the week.

* **Y-axis** — Price in EUR / kWh.
* **X-axis** — Hourly time slots from Monday 00:00 through Sunday 23:00.
* **Bar colour and height** — Taller, darker bars represent the **High Tariff** rate; shorter, lighter bars represent the **Low Tariff** rate.

A legend in the top-right corner of the chart shows the exact rates, for example:

| Band            | Rate            |
| --------------- | --------------- |
| **Low Tariff**  | 0.296 EUR / kWh |
| **High Tariff** | 0.385 EUR / kWh |

The chart makes it easy to see at a glance when expensive and cheap periods occur throughout the week. For a household on a dual tariff, the high-tariff periods typically correspond to daytime hours on weekdays, while nights and weekends fall under the low tariff.

## High Tariff Schedule

Below the chart, a table lists the exact **high-tariff windows** for each day of the week:

| Weekday   | High Tariff   |
| --------- | ------------- |
| Monday    | 07:00 – 19:00 |
| Tuesday   | 07:00 – 19:00 |
| Wednesday | 07:00 – 19:00 |
| Thursday  | 07:00 – 19:00 |
| Friday    | 07:00 – 19:00 |
| Saturday  | —             |
| Sunday    | —             |

All hours outside the listed windows are charged at the low-tariff rate. The schedule varies by tariff provider, so the exact windows may differ between households.

### Tariff Types

The platform supports different tariff structures depending on the household's electricity contract:

* **Single Tariff** — A flat rate applies at all times. The chart shows bars of uniform height.
* **Dual Tariff** — Two rate bands (high / low) apply depending on the time of day and day of the week, as shown in the example above. Households on a dual tariff are tagged with the `Dual Tariff` label in the sidebar.
* **Dynamic Tariff -** Any rate that can be applied outside of a single and dual tariff like 15min changed tariffs, tripple tariffs and so on.
