The analysis “EEG reform 2027 and the network package: What will happen to renewable energy sources?” examines how selected measures proposed in the draft EEG 2027 and the grid package could affect investment decisions regarding renewable energy sources (RES). It focuses on measures that influence price bids in EEG auctions and are therefore relevant for both the continued expansion of RES and the development of EEG costs. The analysis distinguishes between measures that affect price bids directly and those that do so indirectly.
Indirect measures affect price bids through the design of auction parameters. As long as competition in the RES auction remains strong, cost-efficient bids can still be expected. If competition weakens, however, price bids may rise and undersubscription may become more pronounced. Direct measures, by contrast, take the form of mark-ups or discounts on price bids and may be differentiated by location. Overall, the reforms could help align renewable energy expansion more closely with cost efficiency and grid compatibility. At the same time, they entail risks of higher bids, more frequent undersubscription, and rising EEG costs.
