A Competitive Fringe in the Shadow of a State Owned Incumbent: The Case of France

Jean-Michel Glachant and Dominique Finon

Year: 2005
Volume: Volume 26
Number: Special Issue
DOI: 10.5547/ISSN0195-6574-EJ-Vol26-NoSI-8
View Abstract

We examine what kind of competitive fringe has been built in France around the State owned incumbent without destroying it or significantly weakening its dominant position; what impacts has this particular reform process on the market in which the incumbent monopolist is still overly dominant; and what more can be done to strengthen the opening of the market while staying in this typical French policy framework (no industrial restructuring and no forced divestiture by the monopolist). We wonder if a larger window of opportunity will open up at some later date for contesting the position of the monopolist, especially when investment in generation resumes.

Carbon Price instead of Support Schemes: Wind Power Investments by the Electricity Market

Marie Petitet, Dominique Finon, and Tanguy Janssen

Year: 2016
Volume: Volume 37
Number: Number 4
DOI: 10.5547/01956574.37.4.mpet
View Abstract

This paper studies wind power development within electricity markets with a significant carbon price as the sole incentive. Simulation of electricity market and investment decisions by System Dynamics modelling is used to trace the evolution of the electricity generation mix over a 20-year period from an initially thermal system. A range of carbon prices is tested to determine the value above which market-driven development of wind power becomes economically possible. This requires not only economic competitiveness in terms of cost-price, but also profitability versus traditional fossil-fuel technologies. Results stress that wind power is profitable for investors only if the carbon price is significantly higher than the price required for making wind power MWh's cost-price competitive on the basis of levelized costs. In this context, the market-driven development of wind power seems only possible if there is a strong commitment to climate policy, reflected in a stable and high carbon price. Moreover, market-driven development of wind power becomes more challenging if nuclear is part of investment options. Keywords: Electricity market, Renewables, Investment, Carbon price, System dynamics modelling.

The Social Efficiency of Electricity Transition Policies Based on Renewables. Which Ways of Improvement?

Manuel Villavicencio and Dominique Finon

Year: 2022
Volume: Volume 43
Number: Number 6
DOI: 10.5547/01956574.43.6.mvil
View Abstract

Climate and energy policies use to be embedded in joint packages with seeming coherent goals on which the electricity sector is targeted. However, the complexity of power systems is rarely fully apprehended while setting up such packages, particularly when technical externalities from variable renewable energies (VRE) become widespread and different sources of flexibility need to be considered. We use a detailed power system model subject to a combination of RE goals and CO2 caps to seize their interplays and propose a methodology to rank the resulting equilibriums in terms of environmental effectiveness and economic efficiency. We show that: only modest levels of VRE develop without subsidies regardless the level of the CO2 cap; technical externalities create trade-offs between VRE penetration and environmental effectiveness; new flexibility technologies may correct or exacerbate these externalities, impacting effectiveness, costs, and coherence of such packages, requiring a sensitive target hierarchization and fine-tuning of such instruments.
