The climate change problem drives a global effort to rapidly decarbonise electricity systems across the globe. Many public and private energy buyers join this effort and highlight their sustainable credentials by procuring renewable energy through Power Purchase Agreements (PPAs). PPAs typically allow for renewable energy to match supply and demand on average over a long period of time. A growing number of public and private energy buyers are interested in 24/7 carbon-free energy (CFE) matching, which means that every kilowatt-hour of electricity consumption is met by carbon-free sources at all times.

We use energy system modeling to investigate the means, costs, and system-level impacts of 24/7 carbon-free energy matching. There are three working packages in the project, each of which looks at a specific aspect in depth. Working package 1 examines the costs and means of pursuing different clean electricity procurement strategies in the European context. Additionally, we examine how the 24/7 clean energy matching affects the rest of the European electricity system. The aim of working package 2 is to analyze the role of space-time load shifting in reducing the resources and costs of 24/7 CFE matching; we also explore the signals companies can use to shape their load. Working package 3 examines the role of 24/7 CFE in accelerating advanced clean energy technologies.

This project is done in a spirit of open and reproducible research. We use only publicly available input data. The whole scientific workflow from the raw input data to optimized electricity system, visualizations and compilation of individual studies is available at GitHub.
