## **What Are Dynamic Electricity Tariffs?**

**Dynamic electricity tariffs** adjust hourly based on electricity market fluctuations. Prices vary according to **supply and demand**— **electricity often costs less when there's abundant wind, sun, or during nighttime**. Tariffs like our [**_SimplyDynamic_**](/content/dynamic-pricing/index.html), offering electricity **at cost price**, provide exceptional value. Prices may even **become negative**, though taxes and levies remain applicable.

By combining our dynamic tariff with the Solar Manager, you can maximize your solar power self-consumption and draw grid electricity only during low-price periods – resulting in greater energy independence and reduced electricity costs.

### **Solar Manager & Dynamic Electricity Tariffs: The Best Solution for Home Storage, Heat Pumps, and Electric Cars**

If you have the **HEMS from Solar Manager**, you can use **dynamic tariffs** to operate energy-intensive devices **during the most cost-effective times**. This means that you can automatically adjust your electricity consumption to the [**_spot market electricity prices_**](https://join.ostrom.de/strompreis?language=en) and thus reduce your electricity costs.

Here's how you benefit:

- **Charge your electric car with solar surplus**: Your **EV** charges automatically when electricity prices are lowest or when you have excess solar power.
- **Control your heat pump with a dynamic tariff**: Your heating and cooling cycles run during optimal **tariff times**.
- **Smart charging of home storage**: Your **battery storage** charges with low-cost grid electricity when solar power is insufficient.

Through this **intelligent control**, you save money, reduce grid dependence, and maximize your self-generated power usage.

## **Step-by-Step: How to Link Your Hourly Electricity Prices with the Solar Manager**

In the **Solar Manager app**, you can select the **"EPEX Spot" tariff under "Settings" → "Tariff Settings" → "Dynamic"**. The **_EPEX spot exchange_** is the exchange where Ostrom buys your electricity. Thus, the **dynamic prices of SimplyDynamic and the "EPEX Spot" tariff match**, and you can use this tariff for your optimizations.

You can then decide whether your devices should be powered by **solar energy** or **tariff-optimized with grid electricity**. **This flexibility allows for maximum savings.**

📌 **Note:** The EPEX spot prices **do not include taxes, fees and levies**. We are already working with the **Solar Manager team** on a native integration for Ostrom customers to ensure prices include all costs. If you want to speed up the integration process, contact the Solar Manager team.
