Electricity Liberalisation in Britain: the quest for a satisfactory wholesale market design

Britain was the exemplar of electricity market reform, demonstrating the importance of ownership unbundling and workable competition in generation and supply. Privatisation created de facto duopolies that supported increasing price-cost margins and induced excessive (English) entry. Concentration was ended by trading horizontal for vertical integration in subsequent mergers. Competition arrived just as the Pool was replaced by New Electricity Trading Arrangements (NETA) intended to address its claimed shortcomings. NETA cost over £700 million, and had ambiguous market impacts. Prices fell dramatically as a result of (pre-NETA) competition, generating companies withdrew plant, causing fears about security of supply and a subsequent widening of price-cost margins.electricity, liberalisation, market design, market power

Auctions and trading in energy markets -- an economic analysis

Auctions are playing an increasingly prominent role in the planning and operation of energy markets. Comparing the New Electricity Trading Arrangements to the former electricity Pool in England and Wales requires some analysis of the relative merits of uniform versus discriminatory pricing rules, and use of the gas network in Britain and electricity interconnectors around Europe is allocated on the basis of auction results. In this paper we discuss the changes in the trading arrangements in the electricity industry in England and Wales as well as some of the results to date. We also look at the wider issue of using auctions to replace regulation by market solutions for managing the natural monopolies in energy markets.auctions, electricity, gas, interconnectors, networks

Why Tax Energy? Towards a More Rational Energy Policy

The same fuels are taxed at widely different rates in different countries while different fuels are taxed at widely different rates within and across countries. Coal, oil and gas are all used to generate electricity, but are subject to very different tax or subsidy regimes. This paper considers what tax theory has to say about efficient energy tax design. The main factors for energy taxes are the optimal tariff argument, the need to correct externalities such as global warming, and second-best considerations for taxing transport fuels as road charges, but these are inadequate to explain current energy taxes. EU energy tax harmonisation and Kyoto suggest that the time is ripe to reform energy taxation.tax, energy, oil, optimal tariff, externalities, exhaustible resources, global warming, road charges

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.Electricity, reform, restructuring, regulation, developing countries

Regulatory Challenges to European Electricity Liberalisation

The European Commission proposed to reform the Electricity and Gas Directives to improve access to transmission, increase cross-border capacity, and fully open the electricity and gas markets. The California electricity crisis has weakened support for liberalisation, removed the commitment to full market opening, and raised concerns over supply security. Providing adequate reserve capacity is risky in a competitive wholesale electricity market without suitable contracts, and unattractive to oligopolists unless they face a credible entry threat from IPPs. Ending the domestic franchise could remove the counterparty for the contracts required for adequate investment to sustain competitive pricing. Gas liberalisation is key to making electricity markets contestable and reducing pressures on scarce electricity interconnection capacity. Environmental concerns increase uncertainty and further deter entry, while raising other policy issues that need to be addressed. Compared to the US, much of the EU lacks the necessary legislative and regulatory power to mitigate generator market power. Unless markets are made more contestable, transmission capacity expanded and adequate generation capacity ensured, liberalisation may lead to higher prices.Competition, regulation, electricity, contracts, market power

Missing money and missing markets: Reliability, capacity auctions and interconnectors

In the energy trilemma of reliability, sustainability and affordability, politicians treat reliability as over-riding. The EU assumes the energy-only Target Electricity Model will deliver reliability but the UK argues that a capacity remuneration mechanism is needed. This paper argues that capacity auctions tend to over-procure capacity, exacerbating the missing money problem they were designed to address. The bias is further exacerbated by failing to address some of the missing market problems also neglected in the debate. It examines the case for, criticisms of, and outcome of the first GB capacity auction and problems of trading between different capacity markets.This is the author accepted manuscript.

Reforming UK energy policy to live within its means

Abstract The present pattern of taxation, charging, and providing support has accumulated over time in a haphazard way without the kind of strategic thinking that a long-term economic plan requires. This note sets out the sound economic and public finance principles that could guide the reform of energy taxes and supports primarily in the electricity sector. It argues for ending the RO and Feed-in Tariff schemes and replacing them by demonstrably successful CfD auctions which have dramatically lowered the cost of financing renewables. It argues for a state development bank to leverage cheap finance for low-carbon investments, reforming the form of the contracts, replacing the current alphabet soup of charges by the strandard rate of VAT on all energy and instead funding climate change policies from general taxation, thus exempting the productive sector from distortive charges, and allowing the Carbon Price Support to resume its trajectory, restoring fiscal sanity and balance. Ending all support for the cheapest renewable electricity (on-shore wind) makes no sense and it would be better to have a single auction for all renewables that create learning benefits - which would rule out any subsidies to tidal lagoon

The long-run equilibrium impact of intermittent renewables on wholesale electricity prices

High levels of low variable cost intermittent renewables lower wholesale electricity prices, and the depression of these prices could legitimately be recovered from consumers, preferably through capacity payments. Given that renewables are frequently subsidized for their learning benefits and carbon reduction, this paper asks what part of these subsidies should be recovered from final consumers. In long-run equilibrium, renewables have no impact on the number of hours peaking capacity runs, and its impact is to displace largely baseload capacity. The fall in competitive prices is considerably less than the fall in fossil operating costs and provides a case for only a modest share of total subsidies to be charged to electricity consumers. The paper quantifies the amount that can legitimately be charged

'Core Indicators for Determinants and Performance of Electricity Sector in Developing Countries’

Since the early 1990s, substantial resources and effort have been spent on implementing market-oriented electricity reform in developing countries. Important sectoral, economic, and social dimensions are involved in electricity reform, but empirical analysis and evaluation have been of limited use for testing the economic rationale of reform and policy advice. This may partly be attributed to a lack of generally accepted and measured indicators for monitoring progress, impact and performance, unlike areas such as health, education, environment, sustainable development. In this paper we propose a set of indicators as a first step towards filling this gap and developing a coherent framework for studying electricity reform in developing countries covering resource and institutional endowments, key reform steps, market structure, performance, and various impacts.Electricity, Reform, developing countries
