Renewable Electricity Policy and Market Integration

Thomas P. Tangerås

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

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.



The Rise of Third Parties and the Fall of Incumbents Driven by Large-Scale Integration of Renewable Energies: The Case of Germany

Gert Brunekreeft, Marius Buchmann, and Roland Meyer

Year: 2016
Volume: Volume 37
Number: Bollino-Madlener Special Issue

Abstract:
The energy transition is dramatically changing the electricity supply industry in Germany implying two big trends. First, significant market entry by third parties (i.e., non-incumbents). Based on empirical evidence, we argue that the emergence of third parties is the immediate result of the large-scale integration of renewable energy sources. The electricity supply industry is changing quickly from a top-down, single-firm game to a decentralized multiple-player system, with far-reaching consequences for the governance and regulatory structure. Second, the incumbent players are facing disruptive challenges: under pressure of the energy transition, conventional centralized generation is losing profit margins very quickly. We analyze the disruptive challenges and sketch how the incumbents respond by splitting their activities into an old business, which is likely to be phased-out, and a new, future-oriented business: renewable energies, the distribution business, and customer-oriented solutions.



Cross-subsidies Tied to the Introduction of Intermittent Renewable Electricity. An Analysis Based on a Model of the French Day-Ahead Market

Jacques Percebois and Stanislas Pommeret

Year: 2018
Volume: Volume 39
Number: Number 3
DOI: 10.5547/01956574.39.3.jper

Abstract:
The introduction of renewable energy paid off-market disrupts the demand-price relationship in wholesale electricity markets. Drawing on 2015 hourly data from France's electricity transmission network operator (RTE) and the French day-ahead spot market, this paper attempts to quantify the disturbance observed and the transfers of revenues among consumers, producers and providers. This study calculates, through a modeling of the day-ahead market, the impact on conventional electricity producers in France in terms of the loss of economic value owing to the introduction of renewable energies. In the same time consumers benefit from lower electricity prices but have to pay for feed-in tariffs. Renewable electricity producers and electricity providers are also the winners. An estimation of the cross-subsidies induced by the injection of renewable electricity is given.



Co-firing Coal with Biomass under Mandatory Obligation for Renewable Electricity: Implication for the Electricity Mix

Vincent Bertrand

Year: 2019
Volume: Volume 40
Number: Number 4
DOI: 10.5547/01956574.40.4.vber
View Abstract

Abstract:
This paper analyses the effect of recognizing co-firing coal with biomass as renewable electricity. We provide simulations for the French and German electricity mix. Results indicate that, if co-firing is recognized as a renewable, coal may crowd-out traditional renewables with increased generation and additional investments. Regarding CO2 emissions, we find surges when co-firing is recognized as a renewable. The rise is more significant in Germany due to greater coal capacity. In France, the magnitude depends on the share of nuclear with a lower increase when old nuclear plants are prolonged. Finally, we find that recognizing co-firing as a renewable reduces the overall costs for electricity. We balance the cost saving with the increased social cost from higher CO2 emissions. Results show that the cost saving is lower than the increased carbon cost for society with carbon valuation around 100 Euros/tCO2, except in France when old nuclear plants are not decommissioned.



Distortions of National Policies to Renewable Energy Cooperation Mechanisms

Jelle Meus, Hanne Pittomvils, Stef Proost, and Erik Delarue

Year: 2022

Abstract:
The EU endeavors to stimulate the use of renewable energy cooperation mechanisms. These cooperation mechanisms can significantly reduce the policy cost for meeting renewable targets. Several authors, however, have raised concerns that such cooperation mechanisms can be subject to efficiency losses due to different national regulatory conditions, and due to an ill-advised selection of cross-border support instruments. A quantitative evaluation of these effects remains missing. To address this gap, we first introduce a unifying analytical framework to show how optimal cross-border renewable energy trade should be organized and how these mechanisms could be distorted. We then develop a partial equilibrium model, formulated as a large-scale mathematical program with equilibrium constraints, to assess the impact of (i) different national grid cost allocation regimes and (ii) different cross-border feed-in premium implementations. Our results indicate that EU-wide auctions for renewable electricity should (i) not be based on sliding feed-in premiums and should (ii) ideally be discriminatory if national regulatory conditions differ across Member States. We also consider country-level distributional effects and confirm that Member States can lose when engaging in renewable cooperation.



Design of Renewable Support Schemes and Windfall Profits: A Monte Carlo Analysis for the Netherlands

Daan Hulshof and Machiel Mulder

Year: 2022
Volume: Volume 43
Number: Number 5
DOI: 10.5547/01956574.43.5.dhul
View Abstract

Abstract:
This paper investigates to which extent the Dutch feed-in premium scheme for on-shore wind projects has resulted in windfall profits during 2003–2018, a period in which the design of the scheme changed several times. Using Monte Carlo simulations, for 2003, 2009 and 2018, years that represent distinct scheme designs, we estimate the distributions of the required subsidy across virtually all potential on-shore wind projects, and compare them to the granted subsidies. We find that the average windfall profits of randomly drawn projects from the pool of potential investments have decreased over time, largely as a result of differentiating in the subsidy level among projects on the basis of the wind speed at the turbine's location. Despite these improvements, actual investments still experience substantial windfall profits, implying that investors successfully seek out projects that yield the highest windfall profits. Overall, the results imply that accounting for heterogeneity by differentiating in the subsidy level contributes to mitigating windfall profits.
