Wind PPAs, Negative Prices and the Role of Battery Storage

The marketing of wind energy is changing: although long-term EEG subsidies offer a certain degree of planning security, they are increasingly coming into conflict with low subsidy rates, short-term market developments and the growing prevalence of negative electricity prices. These developments present operators and energy marketers with new challenges – but at the same time open up new opportunities.

A promising approach could be to bundle long-term power purchase agreements (PPAs) with co-located battery storage, that is battery storage that shares the location and grid connection of an existing wind turbine. These enable generation and flexibility to be bundled, allowing for swift responses to price signals and thus opening up new marketing strategies.

We will examine how PPAs, price developments and storage technologies interact. The aim is to provide practical insights into what co-location marketing could look like.
