Since 2025, smart meters have been introduced for some households, promising energy savings through dynamic electricity tariffs. The goal is to help consumers save money by using these intelligent electricity meters.
Despite the potential, adoption remains limited. In 2023, Germany had approximately 570,000 smart meters installed out of a total of 52 million electricity meters. These smart meters, also known as intelligent electricity meters, transmit consumer electricity consumption data to the electricity supplier and network operator via the internet.While the intention is to save energy, the impact has been minimal. Nevertheless, the government continues to promote their installation, with the aim of making them available to every private household.
How Smart Meters Function
A smart meter comprises a digital electricity meter and a gateway, which acts as a connection node for transmitting data to third parties. These systems can both send and receive data, with the aim of connecting household appliances in a smart home. This includes electric car sockets,solar systems,and heat pumps. By responding to cheaper electricity rates at different times of the day or night, these devices could be automatically switched on or off. Smart meters store data and can provide precise billing on a minute-by-minute or hourly basis, potentially leading to lower costs and greater energy efficiency.
Smart Meter Mandates
For most consumers, smart meter installation remains voluntary. However, it is already mandatory for households with high electricity consumption exceeding 6,000 kilowatt-hours per year. It also applies to consumers operating electricity or controllable systems, such as photovoltaic systems with a nominal output of more than seven kilowatts, heat pumps, charging stations for electric cars, and night storage heaters. The goal is to have at least 90% of all households in Germany equipped with a smart meter by 2033.
The digital or intelligent electricity meter does not provide any information where electricity could be saved. In order to actually lower your own energy consumption, you need an additional app that makes the power consumption visible live or gives tips for saving energy. This is the only way to understand which devices are power eaters. Such apps offer free competitors A,but usually no network operators.
One disadvantage of smart meters is that they themselves use significantly more electricity than the old Ferraris power meters. Aretz estimates that the operation of a smart meter consumes about 20 to 25 kilowatt hours more a year than previous points. together with all other additional expenses, consumers would have to save 40 kilowatt hours so that the installation and operation of the intelligent electricity meter would expect.
Nevertheless, the IÖW advocates using the smart meter. “You have to swallow the toad because the technology is necessary for the energy transition,” says Aretz. As more renewable energies would be fed into the power grids in the future, flexibility is critically important.Energy from the sun and wind are susceptible to fluctuations. smart meters can adapt favorable times for electricity consumption in dynamic electricity tariffs. In addition, a network relief can be brought about with the technology if less is used up at determination times.

Smart Meters: Are They Saving You Money?
Since 2025, smart meters have been rolling out to homes, promising energy savings through dynamic electricity tariffs. The intent is to help consumers reduce their energy bills using thes smart electricity meters.
What are Smart Meters?
smart meters, also known as intelligent electricity meters, are digital devices that measure and transmit yoru electricity consumption data to your electricity supplier and network operator via the internet. They consist of a digital electricity meter and a gateway, which acts as a connection node.
How Do Smart Meters Work?
Smart meters are designed to work with smart home appliances like electric car sockets, solar systems, and heat pumps. They store data and can provide detailed billing on a minute-by-minute or hourly basis. This allows for potential savings by responding to fluctuating, cheaper electricity rates at different times of the day or night by automatically turning appliances on or off.
Are Smart Meters Mandatory?
While the goal is to have at least 90% of households in Germany equipped with a smart meter by 2033, installation remains mostly voluntary. However, there are some exceptions. Smart meters are *mandatory* for:
- Households with high electricity consumption exceeding 6,000 kilowatt-hours per year.
- Consumers operating electricity or controllable systems, such as:
- Photovoltaic systems with a nominal output of more than seven kilowatts.
- Heat pumps.
- Charging stations for electric cars.
- Night storage heaters.
Do Smart Meters Actually Save Energy?
While the intention is to help you save energy,the impact has been minimal.The digital electricity meter itself does not provide any data on where you can save electricity. You need a separate app that gives you live power consumption data or provides energy-saving tips. This helps you identify “power-eaters” in your home.These apps are often available from competitors but usually not from network operators.
What are the Disadvantages of Smart Meters?
One notable disadvantage is that smart meters consume more electricity than older Ferraris power meters. Aretz estimates that a smart meter uses approximately 20 to 25 kilowatt-hours more per year. Considering this and other additional costs, consumers need to save about 40 kilowatt-hours to justify the installation and operation costs of the intelligent electricity meter.
Are smart Meters Worth It?
Despite the potential drawbacks, the IÖW advocates for using smart meters. The technology is deemed necessary for the energy transition. As renewable energy sources (like solar and wind) become more prevalent,flexibility in the power grid is crucial. Smart meters can help consumers adapt to dynamic electricity tariffs and take advantage of favorable times for electricity consumption. They also offer the potential for network relief by reducing consumption during peak times.
key takeaways: Smart Meters at a Glance
Hear’s a rapid summary of the pros and cons of smart meters:
| Feature | Description |
|---|---|
| Function | measure and transmit electricity consumption data via the internet. Use a digital electricity meter and a data gateway. |
| Potential Benefits | Allows using smart home appliances to take advantage of lower electricity rates. Enables detailed billing for energy consumption. |
| Drawbacks | Smart meters consume more electricity than older meters. The meter itself doesn’t identify energy-saving opportunities – only an additional app does. |
| Mandatory Installation | required for households with very high consumption and those with specific systems like solar panels or heat pumps. |
| Current Adoption | Limited. In 2023, Germany had approximately 570,000 smart meters installed. |
