Economic Effects of Renewable Energy Expansion: A Model-Based Analysis for Germany

The increasing utilization of renewable energy sources (RES) is a major energy policy strategy in many countries worldwide. Germany is a forerunner in the deployment of RES and has ambitious goals for the future. The support and use of renewables affects the economy: It creates business opportunities in sectors producing renewable energy facilities, but comes with costs related to supporting its deployment. ...

Improving Congestion Management: How to Faciliate the Integration of Renewable Generation in Germany

In this paper the German congestion management regime is analyzed and future congestion management costs are assessed given a higher share of intermittent renewable generation. In this context, cost-based re-dispatching of power plants and technical flexibility through topology optimization are considered as market-based and technical congestion management methods. To replicate the current market regime ...

Endogenous Production Capacity Investment in Natural Gas Market Equilibrium Models

The large-scale natural gas equilibrium model applied in Egging, 2013 combines long-term market equilibria and investments in infrastructure while accounting for market power by certain suppliers. Such models are widely used to simulate market outcomes given different scenarios of demand and supply development, environmental regulations and investment options in natural gas and other resource markets.. ...

Comparing Three Models for Introduction of Competition into Railways

In this paper we report the use of the open source Spatiotemporal Epidemiological Modeler (STEM, www.eclipse.org/stem) to compare three basic models for seasonal influenza transmission. The models are designed to test for possible differences between the seasonal transmission of influenza A and B. Model 1 assumes that the seasonality and magnitude of transmission do not vary between influenza A and ...

Assessing the Strength and Effectiveness of Renewable Electricity Feed-in Tariffs in European Union Countries

In the last two decades, feed-in tariffs (FIT) have emerged as one of the most popular policies for supporting renewable electricity (RES-E) generation. A few studies have assessed the effectiveness of RES-E policies, but most ignore policy design features and market characteristics (e.g. electricity price and production cost) that influence policy strength. We employ 1992-2008 panel data to conduct ...

A Note on Allowing Negative Energy Prices in a Discretely Constrained MPEC

Renewable Electric Energy Integration: Quantifying the Value of Design of Markets for International Transmission Capacity

Integrating large quantities of variable renewable electricity generation remains a political and operational challenge. One of the main obstacles in Europe to installing at least 200 GWs of power from variable renewable sources is how to deal with the insufficient network capacity and the congestion that will result from new flow patterns. We model the current methodology for controlling congestion ...

The Integration of Renewable Energies into the German Transmission Grid: A Scenario Comparison

This article presents a quantitative assessment of the need for electricity transmission capacity investments in Germany for 2030. Congestion is analyzed and its possible relief through appropriate grid reinforcements as those described in the Ten Year Network Development Plan (TYNDP) of the European Commission. Congestion is investigated in three scenarios which differ in the location of power resources ...

Development Scenarios for the North and Baltic Seas Grid: A Welfare Economic Analysis

The North and Baltic Seas Grid is one of the largest pan-European infrastructure projects, increasing the potential of harnessing large amounts of renewable energy. This paper addresses the economic implications of different development scenarios of the North and Baltic Seas Grid on individual countries and stakeholders which may raise concerns about the implementation in largely nationally dominated ...

The Strategic Use of Private Quality Standards in Food Supply Chains

We explore the strategic role of private quality standards in food supply chains. Considering two symmetric retailers that are exclusively supplied by a finite number of producers and endogenizing the suppliers' delivery choice, we show that there exist two asymmetric equilibria in the retailers' quality requirements. Our results reveal that the retailers use private quality standards to improve their ...
