The basic metric for any generating plant is the levelised cost of electricity (LCOE). Some of the cost is usually debt financed. [48] Some analysts argue (for example Steve Thomas, Professor of Energy Studies at the University of Greenwich in the UK, quoted in the book The Doomsday Machine by Martin Cohen and Andrew McKillop) that what is often not appreciated in debates about the economics of nuclear power is that the cost of equity, that is companies using their own money to pay for new plants, is generally higher than the cost of debt. According to the report, a typical nuclear power plant may operate in a relatively rural area and contribute upward of $400 million annually to the local and regional economics. Re-licensing is but one factor that affects nuclear power economics. The worst case nuclear accident costs are so large that it would be difficult for the private insurance industry to carry the size of the risk, and the premium cost of full insurance would make nuclear energy uneconomic.[101]. Similar efforts have been utilizing weapons-grade plutonium to produce mixed oxide (MOX) fuel, which is also produced from reprocessing used fuel. In deregulated wholesale electricity markets the economic justification for any capital investment has been decreasing while the actual need increases due to the ageing of existing plants. This is the LCOE as outlined above. This issue was addressed in a February 2015 World Nuclear News editorial. [140][141] Some have suggested that this poses a bottleneck that could hamper expansion of nuclear power internationally,[142] however, some Western reactor designs require no steel pressure vessel such as CANDU derived reactors which rely on individual pressurized fuel channels. However, the impact of intermittent electricity supply on wholesale markets has a profound effect on the economics of base-load generators, including nuclear, that is not captured in the levelised cost comparisons given by the International Energy Agency (IEA) - Nuclear Energy Agency (NEA) reports. U.S. law permits type-licensing of reactors, a process which is being used on the AP1000 and the ESBWR.[65]. Gas combined cycle (550 MWe) capital cost was $700 to $1300/kW and LCOE $41 to $74/MWh. In 2009, the Obama administration announced that the Yucca Mountain nuclear waste repository would no longer be considered the answer for U.S. civilian nuclear waste. A November 2018 report from Lazard compared the LCOE for various generation technologies on the basis of its estimates, related to input from "a wide variety of industry participants". One country, South Korea, experiences sustained construction cost reductions throughout its nuclear power experience. The total cost of the project was expected to be about $14 billion. Many more recent reactor designs have been proposed, most of which include passive safety systems. With electricity, the direct (private) costs of generating power at the plant do not usually include the external costs (e.g. In several countries, notably the UK, there is a trend towards greater vendor involvement in financing projects, but with an intention to relinquish equity once the plant is running. "SMRs are expected at best to be on a par with large nuclear if all the competitive advantages … are realised," the report noted. Merchant generating plants rely on selling power into a commodity market which is shaped by policies including those which may favour particular sources of power regardless of their immediate and longer-term deficiencies in relation to the public good. The UK imposes a Climate Change Levy, which continues to 2023. Individual reactor units ranged from 48 MWe to 1650 MWe. [4] Additionally, measures to mitigate climate change such as a carbon tax or carbon emissions trading, would favor the economics of nuclear power over fossil fuel power. US Energy Information Administration, 2013, Levelized Cost of New Generation Resources in the Annual Energy Outlook 2013 Large and rapid increases in cost occurred during the 1970s, especially in the United States. The overall cost competitiveness of nuclear, as measured on a levelised basis (see figure below on Comparative LCOEs and System Costs in Four Countries), is much enhanced by its modest system costs. Any new power plant likely requires changes to the grid, and hence incurs a significant cost for power supply that must be accounted for. Large infrastructure projects of all kinds tend to be over budget and late in most parts of the world, according to research by the University of Lincoln (UK) and the European Union's Megaproject. These decisions are based on long-term planning processes focused on ensuring reliable operation while minimising total costs over the long-term. The 2014 Ecofys report for the European Commission on subsidies and costs of EU energy purported to present a complete and consistent set of data on electricity generation and system costs, as well external costs and interventions by governments to reduce costs to consumers. The Olkiluoto project has been claimed to have benefited from various forms of government support and subsidies, including liability limitations, preferential financing rates, and export credit agency subsidies, but the European Commission's investigation didn't find anything illegal in the proceedings. In Illinois, in December 2016 the Future Energy Jobs Bill was passed, with a core feature being the establishment of the Zero Emission Standard (ZES) to preserve the state’s at-risk nuclear plants, saving 4,200 jobs, retaining $1.2 billion of economic activity annually and avoiding increases in energy costs. Economics of Nuclear Power - Week 7: Nuclear Power Problems and Solutions | Coursera Video created by University of Illinois at Urbana-Champaign for the course "Energy, Environment, and Everyday Life". The recent liberalization of the electricity market in many countries has made the economics of nuclear power generation less attractive,[57][58] and no new nuclear power plants have been built in a liberalized electricity market. While nuclear power in China has been cheaper than solar and wind power, these are getting cheaper while nuclear power costs are growing. The nuclear LCOE is largely driven by capital costs. Where investors add a risk premium to the interest charges applied to nuclear plants, the impact of financing costs will be substantial. Front end fuel cycle costs of 1 kg of uranium as UO2 fuel. [72] The cost of raw uranium contributes about $0.0015/kWh to the cost of nuclear electricity, while in breeder reactors the uranium cost falls to $0.000015/kWh. Generic approaches to fix market failure include imposing costs on negative externalities such as CO2 emissions, providing compensation to support positive externalities, and government ownership of sectors likely to experience market failure. LCOE figures at a 3% discount rate range from $29/MWh in Korea to $64/MWh in the UK, at a 7% discount rate from $40/MWh (Korea) to $101/MWh (UK), and at a 10% rate $51/MWh (Korea) to $136/MWh (UK). For a five-year construction period, a 2004 University of Chicago study shows that the interest payments during construction can be as much as 30% of the overall expenditure. For nuclear power (2200 MWe plant), capital cost including financing (at a high discount rate) ranged from $6500 to $12,250 per kilowatt, and the LCOE accordingly varied from $112 to $189/MWh. Funding is available and has been collected since 1978 under the Canadian Nuclear Fuel Waste Management Program. [30], Some independent reviews keep repeating that nuclear power plants are necessarily very expensive,[31][32] and anti-nuclear groups frequently produce reports that say the costs of nuclear energy are prohibitively high.[33][34][35][36]. It works within a very tight 50g CO2 per kWh emission constraint for electricity, as required to achieve the targets to combat climate change under the 2016 Paris Agreement. China has 25 reactors under construction,[156][157] However, according to a government research unit, China must not build "too many nuclear power reactors too quickly", in order to avoid a shortfall of fuel, equipment and qualified plant workers. Geographically the total broke down to include EU support of €3.26 billion, and UK €2.77 billion, which was acknowledged as including military legacy clean-up. The amount of uranium present in all currently known conventional reserves alone (excluding the huge quantities of currently-uneconomical uranium present in "unconventional" reserves such as phosphate/phosphorite deposits, seawater, and other sources) is enough to last over 200 years at current consumption rates. OECD electricity generating cost projections for year 2015 on – 5% discount rate, c/kWh. Long-term electricity storage solutions (when/if the technology becomes available) face the same financing problem because these will also be capital-intensive. So while there is some impact, it is minor, especially by comparison with the impact of gas prices on the economics of gas generating plants. Seven UO2 fuel assemblies give rise to one MOX assembly plus some vitrified high-level waste, resulting in only about 35% of the volume, mass and cost of disposal. Ron Cameron, OECD/NEA, July 2013 presentations to Australian Academy of Technological Sciences & Engineering conference in Sydney Rosatom will initially have full ownership of the project company, on a build-own-operate basis, and hopes to reduce that to 51%. Sustaining nuclear viability in the interim is a reasonable and cost-effective insurance policy in the longer term.”. Globally, around 50 nuclear power plants were under construction in 20 countries as of April 2020, according to the IAEA. Grid purchase price is expected to exceed CNY 0.45/kWh at present costs, and drop to 0.43/kWh with reduced capital cost. The FIT can take several forms. This has been tackled differently in various countries. fuel costs and capital cost. The long service life and high capacity factor of nuclear power plants allow sufficient funds for ultimate plant decommissioning and waste storage and management to be accumulated, with little impact on the price per unit of electricity generated. These are without attempting to include the external costs of global warming. Government support is needed to mitigate these risks and make new projects bankable. Thus, once a nuclear power plant has been built, it may make economic sense to keep the plant in service even if the overall cost of generation, including the construction cost, is But LCOE does not take account of the system costs of integrating output into a grid to meet demand, and is therefore a very poor metric for comparing dispatchable generation (coal, gas, nuclear) with intermittent renewables (wind, solar) from any policy perspective. [138] For example, the Areva EPR can slew its electrical output power between 990 and 1,650 MW at 82.5 MW per minute.[139]. The typical front end nuclear fuel cost is typically only 15-20% of the total, as opposed to 30-40% for operating nuclear plants. At the end of a nuclear plant's lifetime, the plant must be decommissioned. Nuclear power - Nuclear power - Economics: A convenient economic measure used in the power industry is known as the levelized cost of electricity, or LCOE, which is the cost of generating one kilowatt-hour (kWh) of electricity averaged over the lifetime of the power plant. In 2018 the UK government announced that it was considering a regulated asset base (RAB) model for future nuclear power plant projects as an alternative to CfDs. For the first two-year period nuclear generators received ZECs of $17.54/MWh, paid by the distribution utilities (and hence eventually ratepayers) but otherwise similar to the federal production tax credits applying to renewables since 1993 on an inflation-adjusted basis, though at a lower rate than its $23/MWh for wind. In China it is estimated that building two identical 1000 MWe reactors on a site can result in a 15% reduction in the cost per kW compared with that of a single reactor. Price signals in the spot market for electricity supply do not provide a guide on the return that might be achieved over the long-term, and fail to create an incentive for long-term investment in generation or transmission infrastructure, nor do they value diversity of supply. The operators were not injured. Nuclear plants create more jobs than other forms of energy. Existing plants function well with a high degree of predictability. [166][167] As of October 2011, plans for about 30 new reactors in the United States have been reduced to 14. Professor of science and technology Ian Lowe has also challenged the economics of nuclear power. Nadira Barkatullah, Financing Nuclear Power Projects: Challenges and Approaches, World Nuclear Association 2014 Symposium Additionally, since 2000, 12–15% of world uranium requirements have been met by the dilution of highly enriched weapons-grade uranium from the decommissioning of nuclear weapons and related military stockpiles with depleted uranium, natural uranium, or partially-enriched uranium sources to produce low-enriched uranium for use in commercial power reactors. Nuclear power plants are expensive to build but relatively cheap to run. Jessica Lovering, Arthur Yip, Ted Nordhaus, Historical construction costs of global nuclear power reactors, Energy Policy, 91, p371-382 (April 2016) Analysis of the economics of nuclear power must take into account who bears the risks of future uncertainties. To pay for the cost of storing, transporting and disposing these wastes in a permanent location, in the United States a surcharge of a tenth of a cent per kilowatt-hour is added to electricity bills. The system cost is minimal with dispatchable sources such as nuclear, but becomes a factor for intermittent renewables whose output depends on occassional wind or solar inputs. It found, after reviewing trends in nuclear power plant construction since 1951, that the average 1,000MW nuclear power plant would incur an average economic loss of 4.8 billion euros ($7.7 billion AUD). For all technologies, a $30 per tonne carbon price was included. Grid-level system costs for intermittent renewables are large ($8-$50/MWh) but depend on country, context and technology (onshore wind < offshore wind < solar PV). As fossil fuel generators begin to incur real costs associated with their impact on the climate, through carbon taxes or emissions trading regimes, the competitiveness of new nuclear plants will improve. For prospective new nuclear plants, the fuel component is even less significant (see below). Costs are incurred while the generating plant is under construction and include expenditure on the necessary equipment, engineering and labour, as well as the cost of financing the investment.The overnight cost is the capital cost exclusive of financing charges accruing during the construction period. A peer-reviewed study in 2017, undertaken by the Energy Innovation Reform Project (EIRP), with data collection and analysis conducted by the Energy Options Network (EON) on its behalf, compiled extensive data from eight advanced nuclear companies that are actively pursuing commercialization of plants of at least 250 MWe in size. This is particularly so where the comparison is being made with coal-fired plants, but it also applies, to a lesser extent, to gas-fired equivalents. 18: NRC Information Digest 2006–2007", "UxC Nuclear Fuel Price Indicators (Delayed)", "Uranium resources sufficient to meet projected nuclear energy requirements long into the future", "Uranium Supplies: Supply of Uranium – World Nuclear Association", "Processing of Used Nuclear Fuel – World Nuclear Association", "Military Warheads as a Source of Nuclear Fuel | Megatons to MegaWatts – World Nuclear Association", "Safe Transportation of Spent Nuclear Fuel", "Management of spent nuclear fuel and radioactive waste", "Fukushima two years on: the largest nuclear decommissioning finally begins", "Chernobyl nuclear plant to be decommissioned completely by 2013", "Nuclear Power:Still Not Viable without Subsidies", https://www.cnn.com/2018/03/15/asia/north-korea-nuclear-reactors-activity/index.html, "Embrittlement of Nuclear Reactor Pressure Vessels", "Providing all Global Energy with Wind, Water, and Solar Power, Part I: Technologies, Energy Resources, Quantities and Areas of Infrastructure, and Materials", "Fukushima: Consequences of Systemic Problems in Nuclear Plant Design", "Fukushima Crisis Worse for Atomic Power Than Chernobyl, UBS Says", "Viewpoint: Fukushima makes case for renewable energy", "Passively safe reactors rely on nature to keep them cool", "Nuclear Dilemma: Adequate Insurance Too Expensive", Publications: Vienna Convention on Civil Liability for Nuclear Damage, "Consolidated federal laws of canada, Nuclear Liability and Compensation Act", "Consolidated federal laws of canada, Nuclear Liability Act", "Civil Liability for Nuclear Damage – Nuclear Insurance", "Increase in the Maximum Amount of Primary Nuclear Liability Insurance", "Publications: International Conventions and Legal Agreements", "Press Communiqué 6 June 2003 – Revised Nuclear Third Party Liability Conventions Improve Victims' Rights to Compensation", A utility's credit quality could be negatively impacted by building a new nuclear power plant, "Update of the MIT 2003 Future of Nuclear Power Study", "Levelized Cost and Levelized Avoided Cost of New Generation Resources in the Annual Energy Outlook 2015", "Levelized Cost and Levelized Avoided Cost of New Generation Resources in the Annual Energy Outlook 2019", Lazard's Levelized Cost of Energy Analysis - Version 13.0, "Nuclear: Carbon Free, but Not Free of Unease", "German grid operator sees 70% wind + solar before storage needed", "New material promises 120-year reactor lives", "NRC: Backgrounder on Reactor License Renewal", https://www.lazard.com/media/438038/levelized-cost-of-energy-v100.pdf, "THE NET BENEFITS OF LOW AND NO-CARBON ELECTRICITY TECHNOLOGIES", "Comparing the Costs of Intermittent and Dispatchable Electricity-Generating Technologies", "Fourteen alleged magical properties coal and nuclear plants don't have", "Can high nuclear construction costs be overcome? But secondly it depends on the market into which the power is sold, where the producer and grid operator run into a raft of government policies often coupled with subsidies for other sources. The increasing involvement of reactor vendors is a recent development. The £100 million vessel, the Akademik Lomonosov, is the first of seven plants (70 MWe per ship) that Moscow says will bring vital energy resources to remote Russian regions. This results in a maximum combined primary+secondary coverage amount of up to $13.06 billion for a hypothetical single-reactor incident. Reprocessing of used fuel increases utilization by approximately 30%, while the widespread use of fast breeder reactors would allow for an increase of "50-fold or more" in utilization. [69] As of 2013, half the cost of reactor fuel was taken up by enrichment and fabrication, so that the cost of the uranium concentrate raw material was 14 percent of operating costs. In the USA, investment in new capital-intensive plant is going ahead only in states where cost-recovery can be assured. about 9 GWe by E.On and RWE in Germany to 2013, and a further 7.3 GWe expected there (apart from nuclear capacity). These design considerations serve to significantly mitigate or totally prevent major accidents from occurring, even in the event of a system failure. The problems of nuclear accidents and nuclear waste highlight the very large implicit subsidy that nuclear power has enjoyed in the U.S. and that cannot be ignored. There are a range of possibilities for financing, from direct government funding with ongoing ownership, vendor financing (often with government assistance), utility financing and the Finnish Mankala model for cooperative equity. The main economic risks to existing plants lie in the impacts of subsidised intermittent renewable and low-cost gas-fired generation. For all practical purposes, nuclear power's economic gains are privatized, while its risks are socialized".[96]. While the returns may be very great, they're also very slow. In September 2015 a Brattle Group report said that the five nuclear facilities in Pennsylvania contribute $2.36 billion annually to the state's gross domestic product and account for 15,600 direct and secondary full-time jobs. [88], "Construction of the ELWR was completed in 2013 and is optimized for civilian electricity production, but it has "dual-use" potential and can be modified to produce material for nuclear weapons. Nuclear Energy Institute, US generating cost data If it does not for any reason, and the developer cannot share first-of-a-kind costs across both, the strike price is to be £92.50/MWh. The nuclear costs estimated by Lazard were well above those in the IEA-NEA study based on existing projects, with well-referenced data. A floor price for ‘carbon’ to support de-carbonisation. At 3% discount rate, nuclear was substantially cheaper than the alternatives in all countries, at 7% it was comparable with coal and still cheaper than CCGT, at 10% it was comparable with both. In Germany, a tax was levied on nuclear fuel that required companies to pay per gram of fuel used over six years to 2016. The temperature was below the operating temperature. [97], In Canada, the Canadian Nuclear Liability Act requires nuclear power plant operators to obtain $650 million (CAD) of liability insurance coverage per installation (regardless of the number of individual reactors present) starting in 2017 (up from the prior $75 million requirement established in 1976), increasing to $750 million in 2018, to $850 million in 2019, and finally to $1 billion in 2020. [85] Chernobyl is not yet decommissioned, different estimates put the end date between 2013[86] and 2020. In June 2015 a study, Economic Impacts of the Indian Point Energy Center, was published by the US Nuclear Energy Institute, analyzing the economic benefits of Entergy’s Indian Point 2&3 reactors in New York state (1020 and 1041 MWe net). If the share of such renewables increases above a nominal proportion of the total then system costs escalate significantly and readily exceed the actual generation cost from those sources. This would drive up current prices. Normally these costs are expressed relative to a unit of electricity (for example, cents per kilowatt hour) to allow a consistent comparison with other energy technologies. By 2014 only 10% of investment was directed into deregulated markets. Nuclear power construction costs have varied significantly across the world and in time. Cost reductions of 40% were achieved by boosting enrichment levels and burn-up.
