Identifying options for regulating the coordination of network investments with investments in distributed electricity generation

This paper analyses two effects of the current Dutch regulation on the system operators of the electricity network and on teh decentralised generators of electricity, and suggests a number of improvements in the tariff regulation. The increase in the distributed generation of electricity, with wind turbines and solar panels, necessitates investments in the distribution network. The current tariff regulation in the Dutch electricity industry, with its ex post evaluation of the efficiency of investments and the frontier shift in the x-factor, delays these investments. In the unbundled electricity industry, the investments in the network need to be coordinated with those in the distributed generation of electricity to enable the DSOs to build enough network capacity. The current Dutch regulations do not provide for a sufficient information exchange between the generators and the system operators to coordinate the investments. This paper analyses these two effects of the Dutch regulation, and suggests improvements to the regulation of the network connection and transportation tariffs to allow for sufficient network capacity and coordination between the investments in the network and in the generation of electricity. These improvements include locally differentiated tariffs that increase with an increasing concentration of distributed generators.

Restructuring Russia's Electricity Sector: Towards Effective Competition or Faux Liberalisation?

Russia in 2003 embarked on the restructuring of its electricity sector. The reform is intended to introduce competition into electricity production and supply, leaving dispatch, transmission and distribution as regulated natural monopolies with non-discriminatory third-party access to the networks. The ultimate aim of the reform is to create conditions that will encourage both investment in new capacity and greater efficiency of both production and consumption. The overall approach embodied in the reform is promising. However, there remains a serious risk that its aims could be subverted by special-interest lobbying during the lengthy implementation phase. If the reform is to succeed, the marketised segments of the sector must be characterised by real competition based on economically meaningful prices. There are two dangers here. The first is that private-sector interests will secure strategic holdings that allow them to exercise market power or even local monopoly power. The second is that, even after the wholesale market is liberalised, the state will retain considerable capacity to hold down electricity prices, if it so chooses, and it could do so in ways that unduly distort the signals the market is sending and deter the very investment that the reform is meant to attract

Are Antidumping Duties an Antidote for Predation?

Since price discrimination and selling below cost arise in the normal course of business and are usually legal for home firms, countering these practices by foreign firms provides a very weak rationale for antidumping duties. If antidumping duties were to provide a systematic defense against predation by foreign firms, however, a strong ''fair-trade'' justification would remain. This paper adapts the classic entry-deterrence analysis of Dixit (1979) and Brander and Spencer (1981) to provide a simple treatment of predation, which is applicable with price leadership as well as quantity leadership. Although situations of cross-border predation appear to be quite rare, foreign firms may sometimes find themselves in leadership positions if they have to make shipments and/or set prices before their home rivals. This paper shows that, in the context of such an international leadership game, predation ma y occur without dumping and vice versa. Further, when dumping and predation do coexist, a sophisticated form of antidumping duty would prevent predation, but the simple antidumping duties that are generally observed in practice will often be insufficient. Consequently, the paper challenges the ''fair-trade'' view of antidumping policy as an antidote for predation and strengthens the foundation of the counter-argument that antidumping constitutes a new insidious form of protectionism and trade harassment, which is of particularly serious concerns for small countries.trade, duopoly, Stackelberg, Cournot, antidumping, predation

Issues and Options for Restructuring Electricity Supply Industries

The electricity supply industry is highly capital-intensive, whose success depends critically upon the management of its investment. In most developing countries investment is poorly managed, poorly maintained, and often inadequate. Inadequate regulation or political control lead to low prices that undermine the finance of investment and give poor incentives for management and operation. The paper argues that regulation must be carefully designed to provide efficient incentives and adequate guarantees to sustain investment and operations and only then will privatisation improve performance and benefit consumers. The paper discusses the evidence for these claims, the circumstances required for full unbundling and liberalisation to be successful, and those where the Single Buyer Model or continued, ideally reformed, state ownership, may be preferable, at least until conditions improve

How Far Does Economic Theory Explain Competitive Nonlinear Pricing in Practice?

Liberalisation of the British electricity market, in which previously monopolised regional markets were exposed to large-scale entry, is used to test the propositions of several recent theoretical papers on oligopolistic nonlinear pricing. Consistent with those theories, each oligopolist offered a single two-part electricity tariff, and a lump sum discount to consumers who purchased both electricity and gas. However, inconsistent with those theories, firms’ two-part tariffs are heterogeneous in ways that cannot be attributed to cost. We establish a series of stylised facts about the nature of these asymmetries between firms and use them to confront established theory

Origins and efficiency of the electric industry regulation in Spain, 1910-1936

The aim of this paper is to discover the origins of utility regulation in Spain, and to analyse, from a microeconomic perspective, its characteristics and the impact of regulation on consumers and utilities. Madrid and the Madrilenian utilities are taken as a case study. The electric industry in the period studied was a natural monopoly2. Each of the three phases of production, generation, transmission and distribution, had natural monopoly characteristics. Therefore, the most efficient form to generate, transmit and distribute electricity was the monopoly because one firm can produce a quantity at a lower cost than the sum of costs incurred by two or more firms. A problem arises because when a firm is the single provider it can charge prices above the marginal cost, at monopoly prices. When a monopolist reduces the quantity produced, price increases, causing the consumer to demand less than the economic efficiency level, incurring a loss of consumer surplus. The loss of the consumer surplus is not completely gained by the monopolist, causing a loss of social surplus, a deadweight loss. The main objective of regulation is going to be to reduce to a minimum the deadweight loss. Regulation is also needed because when the monopolist fixes prices at marginal cost equal marginal revenue there would be an incentive for firms to enter the market creating inefficiency. The Madrilenian industry has been chosen because of the availability of statistical information on costs and production. The complex industry structure and the atomised demand add interest to the analysis. This study will also provide some light on the tariff regulation of the period which has been poorly studied and will complement the literature on the US electric utilities regulation where a different type of regulation was implemented.

Complementary Patents and Market Structure

Many high technology goods are based on standards that require several essential patents owned by different IP holders. This gives rise to a complements and a double mark-up problem. We compare the welfare effects of two different business strategies dealing with these problems. Vertical integration of an IP holder and a downstream producer solves the double mark-up problem between these firms. Nevertheless, it may raise royalty rates and reduce output as compared to non-integration. Horizontal integration of IP holders solves the complements problem but not the double mark-up problem. Vertical integration discourages entry and reduces innovation incentives, while horizontal integration always benefits from entry and innovatio

Russia's gas sector: the endless wait for reform?

The gas industry is perhaps Russia’s least reformed major sector. Prices are regulated, exports are monopolised and the domestic market is dominated by a state-controlled, vertically integrated monopolist, OAO Gazprom. Gazprom combines commercial and regulatory functions, and maintains tight control over the sector’s infrastructure and over information flows within it. The sector as it is currently constituted is highly unlikely to be able to sustain sufficient output growth to satisfy both rising export commitments and domestic demand. There is significant potential for accelerating the growth of non-Gazprom production and making gas supply in Russia more competitive, but this will require fundamental reform. The proposals for reform advanced in the paper address two sets of issues. First, there is an urgent need to increase transparency in the sector and transfer many of the regulatory functions now performed by Gazprom to state bodies. Secondly, there is a longer-term need for a considerable degree of unbundling of Gazprom. In particular, it would be desirable to remove control of the sector’s transport infrastructure from the company and to revise the arrangements governing gas exports to non-CIS states, which are currently monopolised by Gazprom. At the same time, recent increases in domestic gas tariffs must continue until internal gas prices rise above full, long-term cost-recovery levels

Trade, Foreign Direct Investment or Acquisition: Optimal Entry Modes for Multinationals

We examine multinationals’ optimal entry modes into foreign markets as a function of market size, FDI fixed costs, tariffs and transport costs. Our results highlight why large countries are more likely to attract acquisition investment, while intermediate-sized countries may be served predominantly through trade, even in the presence of high tariffs. Small countries are most likely to experience either FDI or no entry. We also show how these results vary with the competition intensity in the host country. FDI fixed costs, tariffs and transport costs are crucial not only in determining whether to engage in FDI or trade, but they are also shown to influence the acquisition choice as trade and FDI threats influence the acquisition price. Finally we explore the welfare implications of tariff reductions for both the local firm and the multinational and investigate political motives to impose endogenous tariffs that influence not only the welfare of a local firm, but also the entry mode of the multinational

Pricing Structures in the Deregulated UK Electricity Market

As residential energy markets open to competition, consumers can choose from a range of tariffs offered by different suppliers. We examine the relationship between the fixed charge levied on each consumer, and the variable charge per unit of energy used across all these tariffs. Data are the tariffs offered in April 2002 in the 14 electricity regions of Great Britain by seventeen suppliers, seven of whom operate nationally. Our analysis focuses on the revenue trade-off for the company. We identify the effect of payment method on the relationship between fixed and variable charge. We find significant effects of the distribution and transmission charges which the suppliers pay in each area, as well as the size of the market both by number of customers and area; and confirm that incumbents charge significantly more that entrants. We also find significant differences between the prepayment and credit tariffs
