| | NOVEMBER 20208CIOReviewIN MY OPINIONAt Acciona, we are always on the lookout for transformative technologies. We are in the business of sustainable infrastructure, supplying renewable energy to more than six million homes and building critical urban infrastructure such as mass transport systems, hospitals, and water treatment plants worldwide. In blockchain, we have found a technology that promises to be a catalyst of change for our businesses, and for our relationship with clients.Certifying the Renewable Origin of EnergyOne of the most exciting uses we have for blockchain is to guarantee the renewable origin of the energy we produce. Acciona's Greenchain platform is an energy traceability tool that allows our customers to track the origin of the power they consume. Given that one electron is very much like another By Diana Martin Romero, Manager of Blockchain. Digital Innovation Hub, AccionaBLOCKCHAIN: A CATALYST OF CHANGE Diana Martin Romeroelectron, and that all electrons travel down the same transmission networks--whatever their origin-- Acciona's Greenchain platform time stamps all the electrons leaving our renewable energy plants. Because this record is both unique and immutable, we can match the output of our plants to the daily assignments to our clients. Our clients get daily and accumulated monthly data of the energy we have supplied and the origin of that power, including, the location of the plants and a breakdown of renewable energy by source (solar, wind, hydro and so on).We are now testing the integration of social and environmental data on the Greenchain platform. This will allow our clients to measure the impact they create by choosing green energy over carbon-intensive alternatives. We see this as a valuable service, not only as a CSR auditing tool for our clients, but also as a way of getting them to share our commitment to building a more sustainable future. Singing From the Same Hymn SheetAcciona also sees enormous potential for blockchain platforms wherever there is a need for the greater traceability, safety, and transparency in our interaction with clients. Even on construction sites, blockchain can make us more efficient. We are testing the use of a blockchain platform for QR blueprint codes, to ensure that everyone on a project--from the client to the site manager--is working off the same blueprint and with the most up-to-date version of the project's specs.
