Updating renewable energy certificate markets via integration of smart meter data, improved time resolution and spatial optimization

This paper illustrates the processes and properties of the German guarantees of origin register (GOR) as well as its properties and European integration. Evaluations and figures about guarantees of origin show the general lack of scaling due to the increasing amount of unsubsidized renewables starting in 2020. Therefore a new platform-based system is proposed, supplementing the trade of guarantees of origin with an ex-post optimization of certificate allocation to increase transparency, accuracy and achieve a steering effect. This optimization is formally introduced and includes spatial information as well as high time resolutions. Additional use cases are presented and their type of mathematical implementation is shown. The shift of the current register design towards a platform-based system finally leads to further added value, as shown in the paper.
