Renewable Electricity Policy and Market Integration

Thomas P. Tangerås

Year: 2015
Volume: Volume 36
Number: Number 4
DOI: 10.5547/01956574.36.4.ttan

Abstract:
I analyze renewable electricity policy in a multinational electricity market with transmission investment. If national policy makers choose support schemes to maximize domestic welfare, a trade policy motive arises operating independently of any direct benefit of renewable electricity. The model predicts electricity importing (exporting) countries to choose policies which reduce (increase) electricity prices. A narrow pursuit of domestic objectives distorts transmission investment, and thereby market integration, below the efficient level. Distortions cannot be corrected by imposing national renewable targets alone. Instead, subsidies to transmission investment and a harmonization of and reduction in the number of policy instruments can improve welfare.



Promoting CCS in Europe: A Case for Green Strategic Trade Policy?

Abstract:
According to IEA (2018), there is a huge gap between the first-best social optimal utilization of Carbon Capture and Storage (CCS) technologies to lower global CO2 emissions and the current, negligible diffusion of this technology. This calls for a financial support mechanism for CCS. We study to what extent promotion of CCS in Europe should be through subsidizing development and production of CCS technologies—an upstream subsidy—or by subsidising the purchasers of CCS technologies—a downstream subsidy. This question is examined theoretically in a stylized model and numerically by using a new approach that integrates strategic trade policy with an economic model of the European energy markets. The theory model suggests that upstream subsidies should clearly be preferred, and this is confirmed by the numerical simulations. For the European power market, the numerical simulations suggest that subsidies to CCS coal power should exceed subsidies to CCS gas power.



A Practitioner's Perspective on Modeling Prices and Trade in a Globalizing Natural Gas Market

Robert D. Stibolt

Year: 2009
Volume: Volume 30
Number: Special Issue
DOI: 10.5547/ISSN0195-6574-EJ-Vol30-NoSI-2
View Abstract

Abstract:
This paper advances some principles for practical application of natural gas models that were used during the EMF 23 study. These principles emphasize a decision-focused perspective, embrace uncertainty, demand consistency of model results with observable facts, are capable of navigating the complexity of systems, and distinguish insight from unattainable precision. The principles are designed to foster the assistance of better decision making by models and modelers.
