There is a clear and strong energy sector dynamic driving production from large centralized units to smaller, decentralized ones, thus opening a world of opportunities and needs for new types of services. Blockchain technology has the potential to become the digital infrastructure that will support this fast-evolving market and will be a key enabler for new emerging use cases such as peer-to-peer trading, crowdfunding, demand-side management, traceability, etc. However, retrieving green energy data securely and integrating it in the blockchain continues to be a major challenge. That’s why we have designed a secure hardware blockchain device to fill the existing void and build a robust and reliable bridge between the physical world of energy production and consumption and the digital world of blockchain.

You want to have a more positive impact on the environment and shift towards cleaner and greener energy sources. You buy green energy or invest in new renewable assets. But how do you prove that your daily consumption is green? How to quantify the overall impact on the planet? How do you know precisely where your green electricity originates from? To answer these questions, The Energy Origin (TEO) was born.

How it works

This autonomous device can be plugged into any type of meter on production and consumption sites to instantly start collecting data in real-time. With the device, the data is then signed and can be registered on any blockchain for decentralized application.

Combining ENGIE’s expertise in the energy sector with LEDGER’s security expertise in the blockchain environment, the device also ensures the data is trustworthy, thanks to an in-built anti-tampering solution and secure elements imbedded into the device. This guarantees the authenticity of data put on the blockchain and its usage in new innovative solutions.

We record in real-time the kWh generated and consumed on-site. Based on your preferences, our matching engine calculates the volumes of energy exchanged between the renewable assets and your sites and the impact in terms of CO2 avoided.

This information is registered in tamper-proof certificates on the blockchain and accessible on TEO with all other production and consumption data.

ENGIE offers

  • Compatibility with the most important blockchain solutions and platforms used in the energy world
  • Real-time access to production and consumption data
  • Enhanced data integrity thanks to an anti-tampering solution



Focus : with TEO tool, you can:

  • Be 100% green
