Survey Exposes Grid Connection Woes for German Solar Plants and Storage

A recent survey by the German Solar Association (BSW-Solar) has revealed significant issues in the grid connection process for photovoltaic power plants and battery storage systems. 72% of participants rated communication during this process poorly, with 63% of planned projects facing delays or rejections.

BSW-Solar has called for urgent simplification, standardization, and digitization of grid access for large photovoltaic plants and storage systems. The association proposes the introduction of non-binding network connection information, binding reservation options, and digitization of network connection requests in the Energy Industry Act (EnWG).

Carsten Koernig, CEO of BSW-Solar, has emphasized the need for political accountability and enforcement of deadlines for grid operators. Currently, the average time for a grid connection request to assignment is nearly four months, with extreme cases taking years. Developers of photovoltaic open-space plants and standalone battery storage projects, 90% and 79% respectively, face similar issues due to lack of grid capacity transparency and non-compliance with response time limits.

The German Federal Government has plans to simplify, standardize, and digitize grid connection for large photovoltaic systems and storage systems. These plans are scheduled to be discussed in the Bundestag soon, with relevant legislative activity referenced in 2025. BSW-Solar's proposals aim to improve the grid connection process, ensuring timely and efficient access for renewable energy projects.
