Acciona­Energia applies blockchain to certify renewable energy origin

A “virtual notary” for clean power: real-time, tamper-proof proof of exactly where every megawatt-hour was made.

AccionaEnergia has become one of the first companies in the world to use blockchain technology to certify the origin of renewable energy. The company sees this as a powerful way to give its clients real-time access to fully transparent data about where their electricity actually comes from. In this initial phase, the technology is operating across two of its generation and storage facilities: the Barasoain wind farm and Acciona's Tudela solar plant, both located in Navarre, Spain.

AccionaEnergia believes that guaranteeing the integrity of renewable energy certificates is becoming more critical every day, and this project represents the first concrete step toward that kind of verifiable transparency. According to the company, the blockchain will function as a "virtual notary" — one capable of performing its verification role far more quickly and in real time. That higher level of assurance is precisely what stakeholders and investors are demanding as they work to build more credible and robust green-energy profiles.

The blockchain acts as a “virtual notary” — certifying the origin of every unit of clean electricity, in real time.

Because the data resides on a blockchain platform, clients can consult it at any time and from anywhere. According to further reports, the initiative forms part of a broader programme known as Greenchain. Over time, Greenchain is intended to allow customers to verify the origin of renewable energy from any supplier — not just Acciona — making it a genuinely open and industry-wide tool.

Those are the core details of AccionaEnergia's initiative to create a transparent and accountable environment for its clients. There is no question that climate change and global warming represent enormous challenges, and transitioning toward renewable energy remains one of the most reliable ways to address them. The problem is that far too few companies and countries are still taking meaningful steps like these — which is precisely why the ones that do deserve to be recognized and highlighted.
