We're thrilled to announce a new project with Google looking at 24/7 carbon-free Power Purchase Agreements (PPAs). Traditional PPAs for renewable energy have seen rapid growth in recent years, but they only match supply and demand on average over a longer period such as a year. There is increasing interest from corporations such as Google to match their demand with clean energy supply on a truly 24/7 basis, whether that is using variable renewables paired with storage, or using dispatchable clean sources such as geothermal power. In 2020 Google committed to operating entirely on 24/7 carbon-free energy (CFE) at all of its data centres and campuses worldwide by 2030. In this project we will explore different designs for a 24/7 carbon-free PPA, and how their deployment affects the rest of the energy system.
