Smart Meter Initiative

Ostrom is part of the Smart Meter Initiative, launched by Octopus Energy, Tibber, and RABOT Charge, which aims to accelerate the deployment of smart meters in Germany.

Under the "Digital Restart for the Energy Transition" law, all German households will be guaranteed the right to smart meters from 2025.

We are already working with local network operators to develop efficient processes to enable a smooth rollout.

Smart meters play a crucial role in the energy transition. Combined with a dynamic electricity tariff, electricity can be consumed precisely when it is most affordable and typically also the greenest.

As our customers, you not only save money but also enable the shifting of loads to more favorable hours, relieving the grid, and balancing the volatility of renewable energies which are all necessities for the energy transition in Germany.

What is a smart meter?

A smart meter is a device that can accurately monitor and transmit your energy consumption in real time. In contrast to conventional meters, which require manual readings and often result in estimations, smart meters provide detailed and precise information about your energy usage. This data can be transmitted directly to your utility provider, eliminating the need for manual meter readings andensuring that you are only billed according to your actual consumption.

What is a dynamic tariff?

The electricity price on the wholesale energy market varies hourly. We always pass on the wholesale electricity price plus taxes and levies directly to you. In times of heavy winds, sunshine, or at night, electricity is cheaper. We at Ostrom enable you to take advantage of this and consume electricity at the cheapest time.
