A new EWI study compares twelve concepts for coordinating decentralised flexibility. The most efficient are those with location- and time-dependent price signals, but they are also the hardest to implement.
Cost efficiency in the development of the German electricity system can be improved. The EWI shows, using its own electricity system model, that more than 70 billion euros could be saved, and identifies specific levers for improving cost efficiency.
Europe’s gas storage facilities are only around 55 percent full at the end of July 2026 – the second-lowest level for this point in time since 2016. To reach a winter buffer of 80 percent by November, LNG imports would have to more than double.
An EWI analysis compares policy instruments for the locational steering of power plant investments. All of them can improve siting, though often with trade-offs in dispatch efficiency and investment certainty. Combinations appear promising.
Based on the Federal Network Agency’s latest AgNes interim report, the reform of grid fees could make green hydrogen up to 32 ct/kg H2 more expensive. This is less than had been expected prior to the publication of the AgNes interim report.
A threefold faster expansion of large-scale battery storage could cut electricity costs for consumers by up to 2.8 billion euros per year in 2035. This is shown by a new EWI report.
During the 2022/2023 gas crisis, expenditures in the gas system doubled. Procurement and sales of natural gas, in particular, became much more expensive. This is shown in a new brief report by EWI on historical expenditures in the gas system in Germany.
Capacity markets are typically financed through consumer charges. Designing charges to be time-variable incentivises consumers to reduce consumption during periods of scarcity, thereby decreasing capacity requirements and increasing consumer surplus.
Various proposals are being discussed for implementing the RED III industry quota in Germany. A new analysis by EWI shows that the regulatory approach will determine competitiveness and the pace of the energy transition.
