Europäische Energiewirtschaft: hoher Investitionsbedarf für Nachhaltigkeit und Versorgungssicherheit

Damit die Europäische Union ihre selbstgesteckten Energie- und Klimaziele erreichen kann, sind umfangreiche Investitionen in die Stromerzeugung, die Strom- und Erdgasinfrastruktur sowie in die Energieeffizienz notwendig. Eine zentrale Bedeutung kommt dabei dem Stromsektor zu. Dieser DIW Wochenbericht liefert einen Überblick über verschiedene Kostenschätzungen des Investitionsbedarfs im Energiesektor ...

Optimal Infrastructure Investments for Renewable Energy Integration in Germany

We analyze optimal infrastructure investments for the integration of variable renewables in the German electricity system. Using a combined dispatch, transmission, and investment model, we compare four scenarios with different investment options, including gas-fired power plants, pumped hydro storage and transmission lines. In a reference scenario of the year 2024, geographically optimized investments ...

All Quiet on the Eastern Front? Disruption Scenarios of Russian Natural Gas Supply to Europe

The Russian-Ukrainian crisis has revitalized the European concerns of supply disruptions of natural gas as experienced in 2006 and 2009. However, the European supply situation, regulation and infrastructure have changed since: imports aremore diversified, EU member states better connected and a common regulation on the security of supply has been introduced. Nevertheless, several East European countries ...

Network Expansion to Mitigate Market Power: How Increased Integration Fosters Welfare

Lack of transmission capacity hampers the integration of the European electricity market, and thereby precludes reaping the full benefits of competition. We investigate the extent to which transmission grid expansion promotes competition, efficiency and welfare. This work proposes a three-stage model for grid investment: a benevolent planner decides on network upgrades, considering welfare benefits ...

National-Strategic Investment in European Power Transmission Capacity

The transformation of the European energy system requires substantial investment in transmission capacity to facilitate cross-border trade and to efficiently integrate renewable energy sources. However, network planning in the EU is still mainly a national prerogative. In contrast to other studies aiming to identify the pan-European (continental) welfare-optimal transmission expansion, we investigate ...

FTR Allocations to Ease Transition to Nodal Pricing: An Application to the German Power System

A shift from zonal pricing to smaller zones and nodal pricing improves efficiency and security of system operation. Resulting price changes do however also shift profits and surplus between and across generation and load. As individual actorscan lose, they might oppose any reform. We explore how free allocation of financial transmission rights to generation and load can be used to mitigate the distributional ...

Power System Transformation toward Renewables: Investment Scenarios for Germany

We analyze distinctive investment scenarios for the integration of fluctuating renewables in the German power system. Using a combined model for dispatch, transmission, and investment, three different investment options are considered, including gas-fired power plants, pumped hydro storage, and transmission lines. We find that geographically optimized power plant investments dominate in the reference ...

Is There Still a Case for Merchant Interconnectors? Insights from an Analysis of Welfare and Distributional Aspects of Options for Network Expansion in the Baltic Sea Region

Despite the ongoing appetite of financial investors for merchant investments into the European electricity network, the EC is reluctant to approve such undertakings, thus implicitly favoring regulated investments. Based on a two-level model, we analyze the impact of profit-maximizing merchant transmission investment as compared to welfare-maximizing regulated transmission investment. We apply the model ...

Technical Greenhouse-Gas Mitigation Potentials of Biochar Soil Incorporation in Germany

Biochar is a carbon-rich solid obtained from the heating of biomass in the (near) absence of oxygen in a process called pyrolysis. Its deployment in soils is increasingly discussed as a promising means to sequester carbon in soils and, thus, to help mitigate climate change. For a wide range of feedstocks and scenarios and against the baseline of conventional feedstock management, we calculate the technical ...
