Optimized Renewable Grid Connections: Overplanting Cuts Costs

Netzausbaukosten könnten zukünftig stark ansteigen, nicht zuletzt durch den Anschluss erneuerbarer Energien. Wie sich durch Überbauung der Netzanschlüsse Netzausbaukosten einsparen und Effizienzgewinne heben lassen, zeigt eine Kurzstudie des EWI.

Voltage measurement can improve the quality of supply

The current electricity grid regulation hardly incentivises grid operators to systematically measure and maintain voltage quality. A short study by EWI and Fraunhofer-IEG shows options for regulating voltage quality.

Reserves returning to the market: Price dampening comes with side effects

The coalition agreement foresees the reintegration of reserve power plants to the electricity market. However, a new Policy Brief by the EWI shows: The price effect depends on the specific design, while grid charges may increase and investment incentives could decline.
