Site Information What else should I know? Quarterly Installed Solar Data Solar Choice Rates Third, Texas has a unique market structure. It’s complicated, but ERCOT has set up the grid in such a way that it acquires a large amount of power through continuous auctions. Every five minutes, power generators in the state electronically bid into ERCOT’s real-time market, offering to provide chunks of energy at particular prices. ERCOT fills the open needs by selecting the bids that are cheapest and that make the most sense from a grid-management perspective—i.e., the power is being fed into the grid at points where the distribution and transmission systems can handle it. Every 15 minutes, the bids settle—at the highest price paid for electricity accepted in the round. So if 100 MW of electricity are needed, and some producers offer 60 MW at $50 per megawatt-hour, some offer 30 MW at $80 per megawatt-hour, and others offer 40 MW at $100 per megawatt-hour, all the bidders will receive the highest price of $100. (Note: The price ERCOT pays is the wholesale generation charge.)

It identified a variety of factors expected to put a strain on the grid on top of record-breaking demand, including delayed power supply projects and the closure of three major coal-fired power plants.

Welcome to Sommelier Summer Camp Average gas and electricity prices (p/kWh) NV Energy (Nevada Power) Vermont 18.35¢ / kWh 18.04¢ / kWh UP 1.718 % Delaware 13.21 13.40 1.4 108.1 34 At 45,000 MWd/t burn-up this gives 360,000 kWh electrical per kg, hence fuel cost = 0.39 ¢/kWh.Fuel costs are one area of steadily increasing efficiency and cost reduction. For instance, in Spain the cost of nuclear electricity was reduced by 29% over the period 1995-2001. Cost reductions of 40% were achieved by boosting enrichment levels and burn-up. Prospectively, a further 8% increase in burn-up will give another 5% reduction in fuel cost.Uranium has the advantage of being a highly concentrated source of energy which is easily and cheaply transportable. The quantities needed are very much less than for coal or oil. One kilogram of natural uranium will yield about 20,000 times as much energy as the same amount of coal. It is therefore intrinsically a very portable and tradeable commodity.The contribution of fuel to the overall cost of the electricity produced is relatively small, so even a large fuel price escalation will have relatively little effect (see below). Uranium is abundant and widely available.There are other possible savings. For example, if used fuel is reprocessed and the recovered plutonium and uranium is used in mixed oxide (MOX) fuel, more energy can be extracted. The costs of achieving this are large, but are offset by MOX fuel not needing enrichment and particularly by the smaller amount of high-level wastes produced at the end. 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.This 'back-end' of the fuel cycle, including used fuel storage or disposal in a waste repository, contributes up to 10% of the overall costs per kWh, or less if there is direct disposal of used fuel rather than reprocessing. The $26 billion US used fuel program is funded by a 0.1 cent/kWh levy.Operation and maintenance (O&M) costs account for about 66% of the total operating cost. O&M may be divided into ‘fixed costs’, which are incurred whether or not the plant is generating electricity, and ‘variable costs’, which vary in relation to the output. 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.Decommissioning costs are about 9-15% of the initial capital cost of a nuclear power plant. But when discounted over the lifetime of the plant, they contribute only a few percent to the investment cost and even less to the generation cost. In the USA they account for 0.1-0.2 cent/kWh, which is no more than 5% of the cost of the electricity produced.External costsExternal costs are not included in the building and operation of any power plant, and are not paid by the electricity consumer, but by the community generally. The external costs are defined as those actually incurred in relation to health and the environment, and which are quantifiable but not built into the cost of the electricity.The European Commission launched a project, ExternE, in 1991 in collaboration with the US Department of Energy – the first research project of its kind "to put plausible financial figures against damage resulting from different forms of electricity production for the entire EU". The methodology considers emissions, dispersion and ultimate impact. With nuclear energy, the risk of accidents is factored in along with high estimates of radiological impacts from mine tailings (waste management and decommissioning being already within the cost to the consumer). Nuclear energy averages 0.4 euro cents/kWh, much the same as hydro; coal is over 4.0 c/kWh (4.1-7.3), gas ranges 1.3-2.3 c/kWh and only wind shows up better than nuclear, at 0.1-0.2 c/kWh average. NB these are the external costs only. If these costs were in fact included, the EU price of electricity from coal would double and that from gas would increase 30%. These are without attempting to include the external costs of global warming.A further study commissioned by the European Commission in 2014, and carried out by the Ecofys consultancy, calculated external costs for nuclear as €18-22/MWh, including about €5/MWh for health impacts, €4/MWh for accidents and €12/MWh for so-called ‘resource depletion’, relating to the “costs to society of consumption of finite fuel resources now, rather than in the future”. Although Ecofys acknowledges that the resource depletion cost is difficult to calculate since the scarcity of a finite natural resource is already reflected in its market price, and could therefore just as well be zero, a high estimate was asserted using a questionable methodology and without taking account of the potential for recycling nuclear fuel.Another report for the European Commission made by Professor William D’haeseleer, University of Leuven, in November 2013, estimated the cost of a potential nuclear accident to be in the range of €0.3-3/MWh.Pricing of external benefits is limited at present. 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. 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.The likely extent of charges for carbon emissions has become an important factor in the economic evaluation of new nuclear plants, particularly in the EU where an emissions trading regime has been introduced but which is yet to reflect the true costs of carbon emissions. Prices have stayed relatively low within the national and sub-national jurisdictions that currently put a price on carbon emissions. In Europe, since 2013, the European Union Allowance price is stagnating around €5-9/tCO2. The European Union is considering a reform to the Emissions Trading System to ensure more stable and higher permit prices needed to support the delivery of its 1990-2030 greenhouse gas emissions reduction target of 40%.An analysis by the Brattle Group in 2016 showed that zero-emission credits for nuclear power could secure the economic viability of nuclear plants in competition with subsidised renewables and low-cost gas-fired plants. It said: "A typical revenue deficit for a vulnerable nuclear power plant is around $10/MWh," which is equivalent to costing "the avoided CO2 emissions... between $12 and $20 per ton of CO2, varying with the regional fossil fuel mix that would substitute for the plant." It said: "This cost compares favorably with other carbon abatement options such as state policies designed to reduce CO2 emissions from the power sector, as well as with many estimates of the social cost of carbon."“These findings demonstrate that the retention of existing nuclear generating plants, even at a modest operating cost recovery premium for a limited period, represents a cost-effective method to avoid CO2 emissions in the near term and would enable compliance with any future climate policy at a reasonable cost. Sustaining nuclear viability in the interim is a reasonable and cost-effective insurance policy in the longer term.”Under New York's Clean Energy Standard (CES), zero-emission credits (ZEC) will be implemented in six tranches over a period of 12 years starting April 2017. For the first two-year period nuclear generators will receive 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. ZECs would escalate to $29.15/MWh over subsequent years.The NY Public Service Commission on 1 August 2016 approved the Clean Energy Standard. The majority vote was reported to be on three main criteria: grid reliability, reducing carbon emissions, and maintaining jobs. The governor’s announcement stated: “A growing number of climate scientists have warned that if these nuclear plants were to abruptly close, carbon emissions in New York will increase by more than 31 million metric tons during the next two years, resulting in public health and other societal costs of at least $1.4 billion.”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. The bill provided ZECs similar to those in New York – "a tradable credit that represents the environmental attributes of one megawatt hour of energy produced from a zero emission facility" (such as the nuclear power plants which supply about 90% of the state’s zero-carbon electricity). It will provide up to $235 million annually to support two plants – 2,884 MWe net capacity – for ten years.Other costsIn order to provide reliable electricity supply, provision must be made for backup generation at times when the generating plant is not operating. Provision must also be made to transmit the electricity from where it is generated to where it is needed. The costs incurred in providing backup and transmission/distribution facilities are known as system costs.System costs are external to the building and operation of any power plant, but must be paid by the electricity consumer, usually as part of the transmission and distribution cost. From a government policy point of view they are just as significant as the actual generation cost, but are seldom factored into comparisons of different supply options, especially comparing base-load with dispersed variable renewables. In fact the total system cost should be analysed when introducing new power generating capacity on the grid. Any new power plant likely requires changes to the grid, and hence incurs a significant cost for power supply that must be accounted for. But this cost for large base-load plants is usually small compared with integrating variable renewables to the grid.For nuclear and fossil fuel generators, system costs relate mainly to the need for reserve capacity to cover periodic outages, whether planned or unplanned. The system costs associated with renewable generation relate to their inability to generate electricity without the required weather conditions and their generally dispersed locations distant from centres of demand.The integration of intermittent renewable supply on a preferential basis despite higher unit cost creates significant diseconomies for dispatchable supply, as is now becoming evident in Germany, Austria and Spain, compromising security of supply and escalating costs. At 40% share of electricity being from renewables, the capital cost component of power from conventional thermal generation sources increases substantially as their capacity factor decreases – the utilisation effect. This has devastated the economics of some gas-fired plants in Germany, for instance.In some countries, market design results in a market failure wherby reliable (and low carbon), but capital-intensive technologies (such as large hydro and nuclear) cannot be financed because long-term power purchase contracts are not available, meaning there is no certainty that investments can be recouped. Long-term electricity storage solutions (when/if the technology becomes available) face the same financing problem because these will also be capital-intensive.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. 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. The negligible marginal operating costs of wind and solar mean that, when climatic conditions allow generation from these sources, they undercut all other electricity producers. At high levels of renewable generation, for example as implied by the EU’s 30% renewable penetration target, the nuclear capacity factor is reduced and the volatility of wholesale prices greatly increases whilst the average wholesale price level falls. The increased penetration of intermittent renewables thereby greatly reduces the financial viability of nuclear generation in wholesale markets where intermittent renewable energy capacity is significant. See also Electricity markets section below.An OECD study (OECD Nuclear Energy Agency (2012), Nuclear Energy and Renewables: System Effects in Low-carbon Electricity Systems) found that the integration of large shares of intermittent renewable electricity is a major challenge for the electricity systems of OECD countries and for dispatchable generators such as nuclear. Grid-level system costs for variable renewables are large ($15-80/MWh) but depend on country, context and technology (onshore wind < offshore wind < solar PV). Nuclear system costs are $1-3/MWh.See also paper on Electricity Transmission Grids.Nuclear-specific taxes are levied in several EU countries. In 2014 Belgium raised some €479 million from a €0.005/kWh tax. In July 2015, Electrabel agreed to pay €130 million tax for the year 2016, alongside a fee for life extension of Doel 1&2 (€20 million/yr). From 2017 onwards, a formula will apply for calculating tax contributions, with a minimum of €150 million per year.In 2000 Sweden introduced a nuclear-specific tax on installed capacity, which gradually increased over time; in 2015, the tax raised about €435 million. In June 2016 the Swedish government, amid growing concerns over the continued viability of existing plants, agreed to phase out the tax on nuclear power from 2017 onwards.In Germany, a tax was levied on nuclear fuel that required companies to pay per gram of fuel used over six years to 2016. After various court rulings, in June 2017 the Federal Constitutional Court finally ruled that the nuclear fuel tax was “formally unconstitutional and void,” which meant that the three major utilities could be reimbursed some €6.3 billion paid between 2011 and 2016 – €2.8 billion by E.On, €1.7 billion by RWE and €1.44 billion by EnBW, plus interest.The UK exercises a Climate Change Levy, which continues to 2023. It is a downstream tax on energy delivered to non-domestic users in the UK introduced in 2001. Initially levied against fossil fuels and nuclear, the government removed renewables' exemption in its July 2015 Budget. In 2011 the government introduced a carbon floor price – a mechanism that has long been seen as fundamental to the economics of new UK nuclear power. The government set a minimum of £16 per tonne CO2 from 2013, rising steadily to £30 per tonne in 2020, and £70 per tonne in 2030.See also paper on Energy subsidies and external costs.Electricity marketsThe economics of any power generation depends primarily on what each unit (kWh, MWh) costs to produce and get to the consumer who creates the demand for that power. This is the LCOE as outlined above. 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. Such policies raise the question of what public good is served by each, and whether overall the public good is optimised. Where the outcome is not maximising public good effectively, there is market failure.** This section draws heavily on the Nuclear Economics Consulting Group webpage on Market Failure.A market can work well to achieve its stated objectives, but still result in market failure. This is often explained by externalities – negative or positive impacts of an industry – that are not reflected in the market. With electricity, the direct (private) costs of generating power do not usually include the external costs (e.g. emissions, system costs due to intermittent operation, land use, noise) nor do they account for the benefits of positive externalities (e.g. knock-on economic activity from jobs, system reliability, fuel diversity).Electricity markets rely on direct or private costs to dispatch (i.e. turn on and turn off) generators to meet varying real-time demand for power. Those costs determine merit order of dispatch. Meeting real-time electricity demand is a difficult and challenging process. The electricity markets do this, but do not reflect the externalities of the generators participating in the market and may result in market failure. An electricity market with efficient short-term spot prices should not be expected to achieve other objectives such as lower emissions, long-term system reliability, or implementation of national policy.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. (Generating plants in a regulated or government-owned electricity industry can deliver power essentially on a cost-plus basis, with regulators or governments able to reflect externalities in decisions.) Nuclear power plants provide a range of benefits to society that are not compensated in the commodity electricity market revenue stream. These public benefits include emission-free electricity, long-term reliable operation, system stability, system fuel diversity and fuel price hedging, as well as economic benefits from employment.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. Some US states make zero emission credit (ZEC) payments to nuclear generation to reward the positive externalities. ZECs are similar to the production tax credits applying to wind power, though lower, but are based directly on estimated emission benefits. They mean that the value of nuclear electricity can be greater than the LCOE cost of producing it in markets strongly influenced by low gas prices and subsidies on variable wind generation which has market priority. Without the ZEC payments, nuclear operation may not be viable in this situation.Comparing the economics of different forms of electricity generationIn 2017 the US EIA published figures for the average levelised costs per unit of output (LCOE) for generating technologies to be brought online in 2022, as modelled for its Annual Energy Outlook. These show: advanced nuclear, 9.9 c/kWh; natural gas, 5.7-10.9 c/kWh (depending on technology); and coal with 90% carbon sequestration, 12.3 c/kWh (rising to 14 c/kWh at 30%). Among the non-dispatchable technologies, LCOE estimates vary widely: wind onshore, 5.2 c/kWh; solar PV, 6.7 c/kWh; offshore wind, 14.6 c/kWh; and solar thermal, 18.4 c/kWh.The 2015 edition of the OECD study on Projected Costs of Generating Electricity showed that the range for the levelised cost of electricity (LCOE) varied much more for nuclear than coal or CCGT with different discount rates, due to it being capital-intensive. The nuclear LCOE is largely driven by capital costs. 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. At low discount rates it was much cheaper than wind and PV. Based on a 0% discount rate, LCOE for nuclear soared to three times as much as the 10% discount rate, while that for coal was 1.4 times and for CCGT it changed very little. Solar PV increased 2.25 times and onshore wind nearly twice at 10% discount rate, albeit with very different capacity factors to the 85% for the three base-load options. For all technologies, a $30 per tonne carbon price was included. LCOE figures omit system costs.Comparative LCOEs and system costs in four countries (2014 and 2012)** LCOE plant costs have been taken from Projected Costs of Generating Electricity 2015 Edition. System costs have been taken from Nuclear Energy and Renewables (NEA, 2012). A 30% generation penetration level for onshore wind, offshore wind and solar PV has been assumed in the NEA estimates of system costs, which include back-up costs, balancing costs, grid connection, extension and reinforcement costs. A discount rate of 7% is used throughout, which is therefore consistent with the plant level LCOE estimates given in the 2015 edition of Projected Costs of Generating Electricity. The 2015 study applies a $30/t CO2 price on fossil fuel use and uses 2013 US$ values and exchange rates.Projected nuclear LCOE costs for plants built 2015-2020, $/MWh Customize Your Rate Plan Public Power Enjoy electricity that will remain locked in price for your entire contract term.
