Prosumage of Solar Electricity: Tariff Design, Capacity Investments, and Power System Effects

We analyze how tariff design incentivizes households to invest in residential photovoltaic and battery systems, and explore selected power sector effects. To this end, we apply an open-source power system model featuring prosumage agents to German 2030 scenarios. Results show that lower feed-in tariffs substantially reduce investments in photovoltaics, yet optimal battery sizing and self-generation ...

DIETERpy: a Python framework for The Dispatch and Investment Evaluation Tool with Endogenous Renewables

DIETER is an open-source power sector model designed to analyze future settings with very high shares of variable renewable energy sources. It minimizes overall system costs, including fixed and variable costs of various generation, storage and sector coupling options. Here we introduce DIETERpy that builds on the existing model version, written in the General Algebraic Modeling System (GAMS), and ...

Urteil unterstreicht, wie teuer uns die Atomenergie kommt

Das Bundesverfassungsgericht rügt das Entschädigungsgesetz für die Atomkonzerne und gibt damit einer Klage von Vattenfall Recht. DIW-Energieökonomin Claudia Kemfert kommentiert dies wie folgt:

Linear and Nonlinear Granger Causality between Electricity Production and Economic Performance in Mexico

Understanding the Granger causality directions between electricity production (EP) and Gross Domestic Product (GDP) is helpful for policymakers in order to design, redesign, and implement effective energy policies. Although there are plenty of studies on this issue, no consistent conclusion about said relationship exists. In this paper, we provide an updated analysis for the case of Mexico in the context ...

Techno-Economic Criteria to Evaluate Power Flow Allocation Schemes

We develop novel quantitative techno-economic evaluation criteria for power flow allocation schemes. Such schemes assign which nodes are responsible for which proportion of power flows on a line in a meshed electricity transmission network. As this allocation is, as such, indeterminate, the literature has proposed a number of dedicated schemes. To better understand the implications of applying different ...

An Open Tool for Creating Battery-Electric Vehicle Time Series from Empirical Data: emobpy

There is substantial research interest in how future fleets of battery-electric vehicles will interact with the power sector. To this end, various types of energy models depend on meaningful input parameters, in particular on time series of BEV motor electricity consumption, grid availability, and grid electricity demand. As the availability of such data is highly limited, we introduce the open-source ...

Democratic Quality and Nuclear Power: Reviewing the Global Determinants for the Introduction of Nuclear Energy in 166 Countries

This paper analyzes the nature of democratic development in a nation on the process of introducing nuclear power over the period 1960 - 2017 for an unbalanced panel of 166 countries. Given the involved political process of introducing nuclear power and its political importance, as well as proposals to construct new nuclear reactors in currently about 30 countries, this question is both of historic ...

Costos de generación, inversión y precios del sector eléctrico en México

Electricity prices have seen a consistent upward trend since the implementation of Mexico’s electricity market reform (EMR). This has been interpreted by some as a failure of the EMR. In this paper we study the determinants of such price increases. We calculate the generation cost curve of the Federal Electricity Commission prior to the entry into force of the reform. We then construct daily data on ...

Green Hydrogen: Optimal Supply Chains and Power Sector Benefits

Green hydrogen can help to decarbonize transportation, but its power sector interactions are not well understood. It may contribute to integrating variable renewable energy sources if production is sufficiently flexible in time. Using an open-source co-optimization model of the power sector and four options for supplying hydrogen at German filling stations, we find a trade-off between energy efficiency ...
