Nuclear Privatisation Nuclear Privatisation Research Paper 96/3 15 January 1996 The proposed privatisation of the bulk of the nuclear electricity generation industry raises a number of questions, many of which have been the subject of a recent House of Commons Trade and Industry Committee inquiry. Much of the debate which followed the publication, in May 1995, of the Government's white paper (The Prospects for Nuclear Power in the UK, Cm 2860) has focused on safety and regulatory issues as well as the allocation of liabilities. This paper discusses these specific aspects and summarises the arguments for and against privatisation.

These included the first generation Magnox stations, the second generation Advanced Gas- cooled Reactors, and the Sizewell B Pressurised Water Reactor which has recently become operational. Significantly, the Government also announced a moratorium on the construction of a family of PWR stations similar to Sizewell B. In March 1990, the nuclear-related assets and liabilities of the CEGB and the SSEB were vested respectively in Nuclear Electric plc and Scottish Nuclear Ltd, both government-owned companies. Five years on, the Government has re-examined the commercial case for new nuclear stations, and considered whether part of the industry is now fit for privatisation. A. Terms of reference The Minister for Industry and Energy (Mr Tim Eggar) announced the terms of reference for the nuclear review in a written answer last May:2 Mr. Yeo : To ask the President of the Board of Trade if he will make a statement on the terms of reference for the nuclear review. Mr. Eggar : I am now in a position to announce the terms of reference, timing and format of the nuclear review. This answer has been agreed with my right hon. Friend the Secretary of State for Scotland, who has responsibility for the nuclear power generating industry in Scotland. The Government believe that the future role of nuclear power in the United Kingdom's electricity supply will depend on it proving itself competitive while maintaining rigorous standards of safety and environmental protection. The coal review established that there is a sound economic basis for continuing to operate existing nuclear stations. The nuclear review will not consider whether Sizewell B should be brought on stream. Sizewell B is on course to start operating this year, subject to the receipt by Nuclear Electric of such consents as are required by law. Decisions on these consents are matters for the appropriate Ministers and authorities and are not matters for the review. The review will, however, take into account the decisions made on Sizewell B, whether the consents are granted or refused. The nuclear review will focus on the future prospects for nuclear power. It will examine the economic and commercial viability of new nuclear stations in the United Kingdom, against the background of the Government's energy policy as set out in the White Paper "The Prospects for Coal", Cm. 2235. 1 HC Deb 9 November 1989 cc 1171-79 2 HC Deb 19 May 1994 cc 543-4W 5 Research Paper 96/3 The Government have asked the nuclear generating industry to make the commercial case for new nuclear generating capacity and to make that case publicly available. Whether any new nuclear station could be built with private sector finance will be a key test of that case. The Government would welcome comments on the industry's case, which will be published shortly. The Government also invite submissions from interested parties on whether new nuclear power stations offer particular diversity, security of supply and environmental benefits or disadvantages. The review will examine possible options for introducing private sector finance into the nuclear industry. As part of this, the Government are prepared to consider without commitment representations on whether privatisation would in principle be feasible, and what a practical timescale might be. The review will address the question of how best to manage the substantial nuclear waste and decommissioning liabilities which are currently the responsibility of the public sector, so as to secure value for money for the taxpayer while ensuring necessary safety and environmental standards are met. The review will also assess the existing arrangements to enable the full costs of nuclear power in the United Kingdom to be met, taking account of the Trade and Industry Committee's recommendations on the fossil fuel levy in its report, "British Energy Policy and the Market for Coal," HC 236. Submissions on these issues should be made in writing both to my Department and the Scottish Office, to be received by 30 September. All substantive submissions received by the Government will be made publicly available. Copies will be placed in the Libraries of this House and of the House of Lords. Commercially confidential information in submissions received by the Government, internal papers and advice and reports internal to Government, and advice from external advisers will not be made publicly available in this way. The review will be undertaken by the Department of Trade and Industry and the Scottish Office Industry Department, in consultation with other Government Departments as appropriate. The Government may appoint consultants to advise it on matters relevant to the review as the need arises. My right hon. Friend the Secretary of State for the Environment is announcing today a separate review of radioactive waste management policy, to be conducted in parallel with the nuclear review. The final conclusions of the Review of Radioactive Waste Management Policy3, referred to in the final paragraph of Mr Eggar's written answer, were published in July 1995 following the issue, for consultation, of preliminary conclusions4 the previous year. Many of the areas covered in this radioactive waste review directly impinge on the commercial prospects of 3 Cm 2919, July 1995 4 Review of Radioactive Waste Management Policy. Preliminary Conclusions Department of the Environment, August 1994 6 Research Paper 96/3 nuclear power, most particularly "back-end" costs such as decommissioning redundant plant and disposing of the radioactive waste produced by nuclear stations. A focus of this library research paper is the Conclusions of the Government's Nuclear Review5 which addressed the points outlined in the above terms of reference. Of particular interest are the proposals for privatising a large part of the nuclear industry, though to put these in their proper context it will be necessary to summarise briefly the other areas covered. Notably, these consist of the case for new nuclear generating capacity and the management of radioactive waste including the arrangements for financing the ultimate decommissioning of nuclear facilities. B. The case for new nuclear stations Under Section 36 of the Electricity Act 1989 (cap 29) the Secretary of State's consent is required before any sizeable6 power station is constructed. The Government believes that "public sector support for new nuclear power stations can only be justified by compelling strategic needs"7, making the prospects for new construction heavily dependent on the willingness of private investors to finance new build. The attractiveness to potential shareholders of the present day industry is likely to be influenced by the strength of the commercial case for new nuclear stations. 1. Costs of nuclear power The cost of nuclear power stations, and the competing alternatives such as coal and gas-fired power stations, is usually expressed in pence per kilowatt-hour (p/kWh). This total unit cost takes into account the capital required to construct the power station and decommission it at the end of its operating life. Recurrent costs, such as fuel, operation and maintenance, are also taken into account. Because nuclear power stations are relatively expensive to build, the total unit cost of the electricity generated is particularly sensitive to a combination of interest rates and the amortisation period, or pay-back time.8 A relatively small rise in interest rates could make a new nuclear power station commercially non-viable. 5 The Prospects for Nuclear Power in the UK Cm 2860, May 1995 6 For the purposes of the Act a "sizeable" power station is one with a capacity in excess of 50 megawatts. The Secretary of State may modify this definition by order. 7 The Prospects for Nuclear Power in the UK Cm 2860 para 4.50 8 Nuclear Power in the UK IEE November 1993 7 Research Paper 96/3 Commercial decisions on whether to build a new nuclear station are based on an estimate of the lifetime levelised cost.

  • The UK Experience: Privatization with Market Power
    The UK Experience: Privatization with Market Power David M Newbery Department of Applied Economics Cambridge, UK 8 February 1999 1. Introduction The UK has three quite distinct electricity supply industries (ESIs) in the three different jurisdictions of England and Wales, Scotland and Northern Ireland. In England and Wales (with a population just over 50 million and a peak demand of just over 49 GW) the industry was under public ownership from 1948-90, and for most of this period, the Central Electricity Generating Board (CEGB) operated all generation and transmission as a vertically integrated statutory monopoly, with 12 Area Boards acting as regional distribution monopolies. The CEGB had interconnectors to Scotland and France, with whom it traded electricity. Scotland (with a population of 5.1 million and peak demand of 5.6 GW, including exports of 800 MW to England) has always retained a degree of autonomy (in law and government) within Britain, while England and Wales are normally treated as a single jurisdiction.1 In Scotland there were two vertically integrated geographically distinct utilities, combining generation, transmission, distribution and supply, one serving the north, the other serving the south. Northern Ireland (with a population of 1.7 million and peak demand of 1.5 GW) is physically separate from the mainland, and the grid connection with Eire in the south had been severed by terrorist activity so that it was a small isolated system. It included all four functions within a single vertically integrated state-owned company, Northern Ireland Electricity (NIE). 2. Restructuring and ownership changes The Electricity Act 1989 divided the CEGB, with its 74 power stations and the national grid, into four companies.

    ELECTRICITY PRIVATIZATION IN THE UNITED KINGDOM AND ITS RESULTS Colin ROBINSON Institute of Economic Affairs & University of Surrey －153－ 1. A brief history 1.1 The nationalised period The electricity supply industry in Britain was nationalised by the Electricity Act of 1947, as part of the sweeping programme of nationalising the ‘commanding heights’ of the economy carried out by the 1945-51 Labour Government under Prime Minister Clement Attlee. Prior to nationalisation the industry had been regulated by the state almost from its beginnings in the late nineteenth century and the degree of regulation had grown in the interwar period.1 In 1919, Electricity Commissioners, responsible to the Minister of Transport, were appointed and in 1926 a Central Electricity Board was established to construct and own an electricity grid; the Board could give directions to power station owners and the Commissioners could determine the price of electricity from power stations if the Board and the owners could not agree. Nationalisation was seen at the time as the logical next step in this trend towards greater state involvement in the industry. The initial structure of the industry under nationalisation was a development of earlier regulatory schemes, designed to cope with what was perceived to be a rather complex industry. Most nationalised industries were run by a single corporation with Board members appointed by the responsible Minister. In electricity, however, there were a number of corporations. 1 The history of British electricity supply from the late nineteenth century to 1968 is summarised in R. Kelf-Cohen, Twenty Years of Nationalisation: The British Experience, Macmillan, 1969, especially Chapter 4.

  • Privatisation RESEARCH PAPER 14/61 20 November 2014
    Privatisation RESEARCH PAPER 14/61 20 November 2014 This paper examines the economic policy which came to be known as ‘privatisation’ – the transfer of responsibility for an industry or the ownership of a company from the public to the private sector. From the 1980s until the mid-1990s, privatisation was an important component of economic policy. Privatisation continued after 1997, although there have only been a handful of instances since then and they have often been referred to by other names. After 2010, interest in the policy as an economic tool revived, particularly with the privatisation of Royal Mail. After defining ‘privatisation’, this paper presents a brief history of the policy. An analysis of the motivations behind the policy is followed by a discussion of the different methods of privatisation, including public flotations, management-led buyouts and private sales. We discuss the importance of regulation and competition in privatised industries and present data showing the scale of privatisation in each year since 1970. Finally, we review various strategies for assessing privatisation as a policy and present a chronological table showing each major privatisation by year. The annex to this paper is a collection of short articles which describe the main features of each major privatisation, including the type of sale, the proceeds to government, and other details.

  • Regulation of the Electricity Industry Research Paper 94/93
    Regulation of the Electricity Industry Research Paper 94/93 1 August 1994 This paper examines the regulation of the UK electric industry. It discusses the role of the Director General of Electricity Supply, and the effects of this on prices and competition within the industry. Christopher Barclay Science and Environment Section House of Commons Library REGULATION OF THE ELECTRICITY INDUSTRY I. Introduction The idea of a privatised industry regulated by an independent regulator dates back to the privatisation of the telecommunications industry in 1984. The basic principle has remained largely the same, with a licence being issued by the Secretary of State and the regulator ensuring that the licence conditions are complied with in subsequent years. However, the regulators have far more importance than that simple description would imply. None has a more complex job than the Director General of Electricity Supply, Professor Stephen Littlechild. Some of the complexities relate to the competitive structure in the industry while others stem from the fact that the electricity industry uses coal, nuclear power and gas as fuels, so that decisions about electricity have enormous consequences for other energy industries. It has become increasingly clear that major decisions have to be taken, going far beyond a simple refereeing role to ensure compliance with the terms of the licence. This role has become controversial, with some critics calling for a different system of regulation, either in the form of a Regulatory Commission or with a revised system incorporating greater democratic accountability. This paper sets out the statutory basis for the Director General of Electricity Supply (DGES) and describes how his powers have been used.

  • Regulation of the Uk Electricity Industry
    INDUSTRY BRIEF REGULATION OF THE UK ELECTRICITY INDUSTRY 2002 edition Gillian Simmonds REGULATION OF THE UK ELECTRICITY INDUSTRY 2002 edition CRI Industry Brief Gillian Simmonds Desktop published by Jan Marchant © The University of Bath All rights reserved ISBN PREFACE The CRI is pleased to publish the 2002 edition of its industry brief on the Regulation of the UK Electricity Industry, having updated it for developments since the 1998 edition. It has been prepared by Gillian Simmonds, a Research Officer at the CRI, and supersedes the first edition which was prepared by Carole Hicks, then a Research Officer at the CRI. The brief is part of a set of CRI industry briefs for the utilities and network industries, covering water, energy, transport and communications. The structure and regulation of the electricity industry has changed considerably since 1998, including developments such as the new electricity trading arrangements (NETA), competition in electricity supply and the Utilities Act 2000, which created, amongst other things, separate, independent arrangements for consumer representation (energywatch) and the Gas and Electricity Markets Authority (the ‘Authority’), which took over the powers and duties of the Director General. The new 2002 edition is, therefore, substantially a new document, rather than a ‘revision’. The CRI would welcome comments on the Brief, which can be taken into account as CRI Industry Briefs have to be updated from time to time in line with developments in the Industry, and will be published as a ‘revised’ or subsequent ‘edition’. Comments should be addressed to: Peter Vass Director – CRI School of Management University of Bath Bath, BA2 7AY The CRI publishes work on regulation by a wide variety of authors, covering a range of regulatory topics and disciplines, in its International, Occasional and Technical Paper series.

  • Market Power Mitigation in the UK Power Market
    Market Power Mitigation in the UK Power Market Richard Green* Institute for Energy Research and Policy University of Birmingham Birmingham B15 2TT UK Tel: (+44) 121 415 8216 Fax: (+44) 121 214 7377 Email: [email protected] September 2005 1. Introduction Market power has been a constant theme in the history of the electricity restructuring in England and Wales. When the industry was restructured, the government created three large generating companies, two of which shared almost all the stations capable of setting prices in the industry’s centralised spot market. It soon became apparent that these companies had the ability and the incentive to raise prices to undesirable levels. Over the course of the 1990s, the industry’s regulators attempted to mitigate the duopolists’ market power. They published reports on unacceptable behaviour, making it impossible for the companies to repeat those tactics, while defining what would be allowed in future. The generators twice divested plant to rival companies – once to avoid being referred to the Monopolies and Mergers Commission, once in return for being allowed to merge with electricity retailers. In the end, the regulator and the government together changed the market’s rules, abolishing the Pool that had been at the centre of the original restructuring. At the end of the Pool’s life, prices finally fell below the “competitive” level of new entrants’ costs. We may never know whether abolishing the Pool would have reduced prices, had the market still been concentrated, for it had reached a competitive structure just before it was abolished. This paper discusses market power and its mitigation in the electricity industry of England and Wales.
