Is It Worth It?" /><p>€180 less per year for charging the EV – that&rsquo;s not a promise from a provider, but a concrete real-world calculation: anyone who charges their car at home and has the right tariff simply pays less, because electricity is significantly cheaper at night or when there&rsquo;s plenty of wind and solar energy on the grid.</p> <p>That&rsquo;s exactly what dynamic electricity tariffs make possible. Whether it makes sense for you depends on one key factor.</p> <div class="video-wrapper"> <div class="video-placeholder" onclick="loadIframe(this)"> <img src="https://smarthome-aber-sicher.de/img/sas_youtube.png" alt="YouTube Video"> <div class="play-button"></div> <div class="privacy-notice" style="color: var(--card-text-color-main);"> To load the video, please click the image.

Unlike traditional fixed-price tariffs or time-of-use tariffs with fixed peak and off-peak windows, prices under a dynamic tariff can change every hour or even every quarter-hour.</p> <p>For such a tariff to work, you need either a <strong>smart meter</strong> or an additional device that records your electricity consumption in real time. Only then can your provider match your actual usage data to the dynamic prices.</p> <h2 id="pros-and-cons-of-different-electricity-tariffs">Pros and Cons of Different Electricity Tariffs </h2><table> <thead> <tr> <th>Tariff type</th> <th>Price changes</th> <th>Price guarantee</th> <th>Savings potential</th> </tr> </thead> <tbody> <tr> <td><strong>Fixed tariff</strong></td> <td>None</td> <td>Fixed</td> <td>Low</td> </tr> <tr> <td><strong>Time-of-use tariff</strong></td> <td>Fixed time windows</td> <td>Partial</td> <td>Medium</td> </tr> <tr> <td><strong>Dynamic tariff</strong></td> <td>Hourly / every 15 minutes</td> <td>None</td> <td>High</td> </tr> </tbody> </table> <p>A dynamic tariff is most worthwhile if you own <strong>high-consumption devices</strong> such as washing machines, tumble dryers, dishwashers, or electric vehicles that you can run flexibly.</p> <h2 id="calculation-examples-how-much-can-you-save">Calculation Examples: How Much Can You Save? </h2><h3 id="1-washing-machine-and-tumble-dryer"><strong>1.

For example, you can set your EV to automatically charge during the cheapest hours while still being ready to drive in the morning.</p> <h2 id="my-recommendation-tibber">My Recommendation: Tibber </h2><p>One provider offering dynamic electricity tariffs is <strong>Tibber</strong>. With a monthly base fee of only €3.99 and transparent pricing, Tibber is an excellent choice. Particularly handy: the <strong>Tibber app</strong> shows you hourly electricity prices in advance and makes it easy to reach customer support.</p> <p>If you don&rsquo;t have a smart meter yet, you can use the <strong>Tibber Pulse</strong> device to track your consumption hourly.</p> <h2 id="bonus-100-for-smart-home-devices">Bonus: €100 for Smart Home Devices </h2><p>Tibber currently offers a <strong>refer-a-friend promotion</strong>:</p> <ul> <li><strong>Until 17 January 2024</strong>: €100 for you and €100 for me in the Tibber Store.</li> <li><strong>From 18 January 2024</strong>: Still €50 for both sides.</li> </ul> <p>With this bonus you can buy smart home devices to make your home even smarter.
