Abstract: This chapter aims to analysis the new dynamics at work in EU energy regulation. Since the publication of the European Commission’s ‘Sector Inquiry Report’ in January 2007, European energy companies have felt the cold wind of competition law - many for the first time. In addition, national competition authorities (NCAs) have been actively pursuing abusive market practices - sometimes making innovative use of competition law in the process. Certain energy giants have agreed to unbundle their transmission networks - even when their national governments opposed the inclusion of ownership unbundling in the draft ‘Third Package’ of electricity and gas legislation. In parallel, the Third Package envisages the creation of a new regulatory agency - ACER - to co-ordinate technical crossborder regulatory issues in the internal market. So who will be in the driving seat in the next decade - and will co-ordinated regulatory powers be the preferred approach to market design? Will regulatory rules co-exist alongside competition based controls or will the latter gradually supersede the former? This chapter will examine these critical issues.

Abstract: The creation of competitive wholesale electricity markets allows to evaluate the “arbitrage value” of an electricity storage unit, which stems from buying and storing electricity when prices are low, and selling it when prices are high. The focus of this paper is to demonstrate that the arbitrage value can be highly sensitive with respect to the dimensioning of an electricity storage unit. A simulation model is explored to calculate the arbitrage value of different storage units by finding the optimal hourly operating strategy during one-year period. The results of simulation show that optimizing the dimensioning of a storage unit is as important as choosing the fittest technology. Furthermore we provide evidence that the optimal set-up of a storage unit can adapt to exogenous factors such as grid tariff and local electricity price characteristics. These findings suggest that the maximisation of market value of electricity storage should be based on the optimisation of the dimensioning of the storage unit in specific economic and regulatory environment.

Abstract: How do changes in the market architecture affect the dynamics of deregulated electricity prices? We investigate this issue in the context of the Italian Power Exchange (IPEX), using data on the daily average day-ahead price (PUN) between April 2004 and December 2008. Estimates of baseline time series models (ARMAX and ARMAX-EGARCH) and their forecasting performances suggest that the trend in natural gas prices, deterministic weekly patterns, the impact of perceived temperatures, persistence in conditional volatility and the inverse leverage effect are essential features of the PUN dynamics. We then augment the best-performing models with dummies that account for changes in the market architecture, such as the introduction of contracts for differences (CfDs) to support renewables, trading of white certificates for energy efficiency, and the demandside liberalization. The findings show that changes in the market architecture have only affected the PUN volatility. Specifically, CfDs have mitigated volatility, while white certificates and demand liberalization have increased it. Moreover, after controlling for reforms the inverse leverage effect vanishes, and the persistence in volatility is lower than in the baseline estimates.

Abstract: This paper proposes a probabilistic model to evaluate if a proactive TSO that anticipates the connection of new generators with short construction duration compared to the time needed to reinforce the network is more efficient than a reactive TSO that does not make any anticipation but that may then face higher congestion while the network is being reinforced. This evaluation is made in presence of anticipation costs both related to the study of the project of network investment and to the administrative procedures needed to obtain the building agreement. Our results in terms of social costs clearly show a limit of probability for the connection of generators beyond which a proactive TSO is more efficient than a reactive TSO. Evaluated on realistic cases of connection, this limit of probability is found quite low, which indicates that the proactive behaviour for a TSO shall generally be the optimal one.

Abstract: Reducing the European Union GHG emissions by at least 80% by 2050 will require a near zero carbon electricity, road and rail transport industry, and heating and cooling in buildings. As compared to “business as usual” the amount of energy required will basically vary according to the level of energy efficiency: it is the “system scale”. Then it is the “system design” which will provide the needed carbon-free technologies consisting of renewable, nuclear and fossil fuels with carbon capture and storage. A zero carbon energy system by 2050 is then demonstrated to be feasible. However it is far from easy and requires immediate and substantial policy action. The main policy implications are addressed in this paper. The 5 years 2010-2015 will be decisive in establishing a regulatory environment whereby the EU will be in a position, by 2020, to take the next steps to achieve the 2050 goal.

Abstract: This paper provides an empirical analysis examining the effect of both transaction characteristics and the institutional environment on governance choice. Using a dataset of 237 corporate-specific value chains in the global LNG industry, we introduce inter-organizational trust as a shift parameter. Following transaction cost economics, it is hypothesized that specific investments under uncertainty provide incentives to integrate vertically. Second, it is argued that inter-organizational trust changes the relative costs of vertical integration and non-integration and supports less hierarchical organizational structures. These economic relationships are tested based on probit and ordered probit models. Estimation results provide broad support for both propositions.

Abstract: Cross-border trade remains a contentious issue in the restructuring of the European electricity market. Difficulties stem from the lack of a common market design, the separation between energy and transmission markets and the insufficient coordination between Transmission System Operators (TSOs). This paper analyzes the cross-border trade problem through a set of models that represent different degrees of coordination both between the energy and transmission markets and among national TSOs. We first present the optimal organisation, not implemented in Europe, where energy and transmission are integrated according to the nodal price paradigm and Power Exchanges (PXs) and Transmission System Operators (TSOs) are integrated. This is our reference case. We then move to a more realistic representation of the European electricity market based on the so-called marketcoupling design where energy and transmission are operated separately by PXs and TSOs. When considering different degrees of coordination of the national TSOs' activities, we unexpectedly find that some arrangements are more efficient than the lack of coordination might suggest. Specifically we find that even without a formal coordination of the TSOs' counter-trading operations, non discriminatory access to common counter-trading resources for all TSOs may lead to a partial implicit coordination of these TSOs. In other words, an internal market of counter-trading resources partially substitutes the lack of integration of the TSOs. While a full access to counter-trading resources is a weaker requirement than the horizontal integration of the TSOs, it is still quite demanding. We show that quantitative limitations to the access of these resources decrease the efficiency of counter-trading. The paper supposes price taking agents and hence leaves aside the incentive to game the system induced by zonal systems.

Abstract: Answering to the formidable challenge of climate change calls for a quick transition to a future economy with a drastic reduction in GHG emissions. And this in turn requires the development and massive deployment of new low-carbon energy technologies as soon as possible. Although many of these technologies have been identified, the critical issue is how to make them happen at the global level, possibly by integrating this effort into a global climate regime. This paper discusses the preferred approaches to foster low-carbon energy technologies from a regulatory point of view. Specific promotion policies for energy efficiency and conservation, renewable energy, carbon capture and sequestration, and nuclear power are examined, but the focus is on the regulatory instruments that will be needed for the deployment of enhancements to electricity grids and the associated control systems so that they are able to integrate intelligent demand response, distributed generation and storage in an efficient, reliable & environmentally responsible manner. The paper also comments on the interactions between technology and climate change policies and provides recommendations for policy makers.

Abstract: We investigate the political determinants of liberalization in OECD network industries, performing a panel estimation over thirty years, through the largest and most updated sample available. Contrary to traditional ideological cleavages, we find that right-wing governments liberalize less than left-wing ones. This result is confirmed when controlling for the existing regulatory conditions that executives find when elected. Furthermore, governments’ heterogeneity, proportional electoral rules, and European Union membership all show positive and statistically significant effects on liberalization. Our findings suggest that, despite the conventional wisdom, the political-economic rationale behind liberalization paths in network industries is far from being assessed.

Abstract: European energy policy is characterized by a complex allocation of authority between the European Union and its Member States which results in an intricate interplay of regulatory competence. Knowing the difficulties European countries face in coordinating and proposing common solutions in the area of energy, there is the urgent need to question the legal foundations underlying the decisionmaking process. Institutional paralysis, low reactivity to events and changes as well as systematic political horse-trading across all questions call for an alternative framework allowing some pioneering Member States to promote ad hoc common policies escaping the formal and procedural requirements of EU law. Our paper assesses the legal feasibility of short-run differentiation by means of partial international agreements inspired by the Schengen regime, namely entirely outside the EU framework. The key challenge from a legal point of view is to assess the substantive compatibility of such agreements in energy with the existing rules of the Union. Short run differentiation in energy cannot indeed be assessed at a high level of generalities. We therefore take two areas where legally-binding coordination at the sub-Union level is often called for: nuclear policy and gas security of supply. The possible substantive content of such cooperation is derived from the economic and political literature before legal feasibility is assessed. Our findings suggest that the scope for such agreements is limited for security of gas supply whereas it could be an improved cooperation device in certain areas of nuclear policy.

Abstract: In September 1989, as part of its privatization program, the Government laid down an eight year timetable for opening up to retail competition the entire electricity market of England and Wales, phased over the period 1990-1998. It might be assumed that the Government was in a position to specify all the arrangements, and that this was part of a considered policy to facilitate the introduction and implementation of competition. But previous accounts suggest that the outcome was part of a deal between generators and regional companies to limit competition (Henney 1994), or was intended to set targets to force companies, regulators and government to come up with practical solutions (Helm 2004). The Department of Energy’s internal History of Electricity Privatisation, only now available, shows that there is merit in these last two suggestions. However, it also documents the significantly evolving views within Government as the implications of retail competition became clearer, not least for electricity contracts and for privatization of the coal industry. Initially, retail competition was hardly worth mentioning, later it was a mild concern that could be met by a small tranche of spot-price contracts, by July 1989 the plan was to introduce full competition immediately with short-term instead of long-term contracts. But the industry resisted, and in September 1989 the Government accepted the industry proposal of a franchise monopoly to enable a mix of short, medium and long-term contracts, though it insisted that the franchise should have an eight year limit. The approach may not be a model for others, but it may not be atypical of how governments actually behave in balancing conflicting objectives and practical constraints, save perhaps for the distinctive commitment to competition exhibited by the leading actors here.
