The planned facility's type is one of the key variables influencing construction costs for power producing facilities. Depending on whether they are coal-fired power plants, plants powered by natural gas, solar, wind, or nuclear generator facilities, construction prices might vary greatly. When determining whether an investment in power generation facilities will be lucrative, power generation facility investors must take construction costs between these different types of generation facilities into account.
To assess a favorable rate of return, investors must also consider additional elements, such continuing maintenance expenses and potential future demand. The capital expenditure needed to bring a facility online, however, must be at the core of any estimate. Therefore, a brief examination of the actual costs associated with building various types of power plants is necessary.
It's crucial to remember that realized building costs can be affected by a variety of factors when examining power plant construction costs. For instance, the cost of construction can be significantly impacted by the availability of resources that power manufacturing. The cost of utilizing and developing resources like solar, wind, and geothermal energy will rise over time due to their uneven distribution. Early market entrants will benefit from the most affordable access to resources, whereas more recent projects could have to pay much more to have access to comparable resources.
The lead time of the construction project can be significantly impacted by the regulatory environment where the power plant is located. This can result in higher interest payments and overall construction expenses for projects that need a significant initial capital expenditure. Refer to the U.S. Energy Information Administration's (EIA) 2016 publication, Capital Cost Estimates for Utility Scale Electricity Generating Plants, for further details about the wide range of variables that might affect the costs associated with building power plants.
The price per kilowatt for power plant construction is given. The EIA has donated the data shown in this section. For power producing facilities built in 2015, we will specifically use these costs, which may be found here. This data is the most recent available, although in July 2018, the EIA is anticipated to provide power plant building costs for 2016. The EIA's publications are among the best sources of information for people interested in power plant building costs. The EIA's data helps to highlight the many factors that can affect power plant construction costs as well as ongoing profitability, and to emphasize the complexity of power plant construction costs.
Two of the main factors influencing the price of building a power plant are labour and materials, which together are pushing up construction prices annually in all sectors of the economy. When estimating the overall building costs for power plants, it's crucial to stay on top of changes in both labour and material prices. The process of building a power plant often takes a long time.
The minimum time required to complete a project is one to six years, while some take much longer. The EIA correctly emphasizes the need of taking into account variations in the planned and actual cost of materials and construction over the duration of the project and how they can significantly affect construction costs.
The burden of labor and material expenses are two of the main factors driving up construction costs overall. The cost of materials has increased significantly over the past few months, and if existing policy positions are maintained, expenses may rise even further.
Tariffs on imports from other countries of important metals like steel, aluminum, and iron, as well as timber from Canada, are particularly responsible for the substantial changes in material costs.
Real material prices are currently 10% higher than they were in July 2017. For the foreseeable future, it doesn't seem like this tendency will stop. Steel is very vital for the construction of power plants, therefore continuing tariffs on imported steel could result in a significant cost increase for all types of power plant construction.
Rising labor expenses in the building sector are another factor driving up construction costs. Because of the low participation of millennial in the building trades and the sharp decline in the size of the construction labor force during and after the recession, higher labor costs are being caused by a shortage of skilled personnel.
It will take time to fully observe the impact of these efforts, even though many construction businesses are including career pathway programs to attract more millennial to trade industries.
The urban regions where there is fierce competition for skilled labor are where this labor shortage is most noticeable. Access to trained workers for power plant construction projects close to metropolitan centers may be scarce and expensive.
Wind- The most capacity was added to the electrical grid in 2015 by power plants that used wind as a renewable energy source, without significantly increasing fuel costs. In the United States, there has been a steady increase in the use of wind energy. Power stations that use wind energy increased their capacity by 8,064 megawatts (MW) in 2015. You can see how quickly wind-powered power plants have expanded by comparing this to the 45 MW of capacity added by petroleum-based producing facilities. The average cost to build a wind power facility was $1,661 per kilowatt of installed nameplate output. As a result, 66 generators required a total construction budget of $13,395,684. It is significant to note that the existing regulatory environment and generation prices have a significant impact on the development of wind generators. Consider the difference between the installation of over 8,000 MW in 2015 and the addition of less than 900 MW in 2013 for power plants that rely on wind energy to demonstrate this. The most significant factor in this was the federal production tax credit's expiration at the end of 2012, which prompted investors to delay new wind energy generator installation until the tax credit was reinstated in early 2013. The additional capacity installed in 2015 can be considered as a fresh investment whenever a more advantageous environment arises because of the production lag period.
Natural Gas- Natural gas-fired power facilities have been a major factor in raising grid capacity in previous years, and 2015 was no exception. A total of 6,549 MW in additional capacity was added by natural gas power plants in 2015. The same year, the average cost to build a natural gas power plant was $812 per kilowatt, or $5,318,957 for 74 generators. In natural gas power plants, three basic types of technology are used. The overall building expenses are significantly impacted by each individual technology. Internal combustion engines only made up a minor portion of the increased capacity, with mixed cycle natural gas power plants (4,755 MW) and combustion turbines (1,553 MW) adding the majority of it (240). The full narrative isn't told by this, though. Compared to other types, combined cycle plants run at substantially greater levels of efficiency, since they must have at least one steam turbine and one combustion turbine. Long-term running costs are reduced as a result, but construction capital costs are also greater. Although less expensive to build than combined cycle power plants, combustion turbine natural gas power plants have higher operational expenses due to their lower efficiency. The additional benefit of being able to be erected more quickly than mixed cycle power plants applies to both internal combustion engine and combustion turbine power generators. Their use in circumstances where temporary capacity increases are required to satisfy increasing demand has resulted from this. Additionally, even though combustion turbine plants are less efficient, they are often only used to satisfy demand during peak hours. Contrarily, given to their superior efficiency and lower running costs, combined cycle plants frequently serve to meet baseline demand demands.
Solar- Similar to natural gas, the cost of building a solar power plant is heavily influenced by the underlying technologies used in the facility. The technology used also affects how much power can be produced by solar power plants. As a result, the relationship between solar power plant building costs and their capacity for production is a key factor for investors. For a total capacity increase of 3,192 MW, the average construction cost for all varieties of solar photovoltaic (PV) power plants was $2,921/kW. For a total of 386 generators, the building costs for solar PV plants came to $9,324,095. These figures show that compared to wind and natural gas, solar facilities often produce less capacity growth per generator. The level of production varies among different types of solar PV installations. Fixed-tilt and axis-based tracking installations have important differences from one another. Compared to fixed tilt, axis-based tracking systems have a larger output capacity, which may help offset the higher initial cost of installation. The type of solar PV installation is a different aspect to think about. Thin-film CdTe and crystalline silicon are the two main varieties now available on the market. Each of these varieties has benefits and drawbacks. Because thin-film technology is more recent, thin-film plants have substantially higher average capacities than crystalline silicon plants (74 MW vs. 7 MW). Both plant types cost about the same to build. For instance, crystalline silicone plants cost an average of $2,920/kW for axis-based tracking installations, compared to thin-film plants' average cost of $3,117/kW. Fixed and axis-tilt crystalline silicon installations much outnumbered thin-film installations in 2015, indicating a market preference for crystalline silicon solar power plants in that year.
Nuclear- Even though there haven't been many nuclear power stations built recently, they still make up a significant portion of our energy infrastructure. In reality, the Watts Bar Unit 2 facility, which was finished in 2016, was the most recent nuclear power plant to reach completion. The Watts Bar Unit 1 nuclear power station, the previous nuclear power facility in the UK, was completed in 1996. This project, which was completed after decades of delays, went online over 20 years later. There aren't any totally accurate or recent estimates of the cost to build a nuclear power plant due to the absence of new nuclear plant construction. According to an economic prognosis published by the EIA in 2018, nuclear power plants that were started in 2016 would have a basic overnight cost of $5,148, excluding any changes that might take place in the interim. The lengthy building period for nuclear power plants and the nuclear industry is an important point to keep in mind. The EIA estimates that if building started in 2016, a nuclear reactor and power plant might go online as soon as 2022. If building prices as a whole continue to climb as they have, this makes the construction of nuclear power plants more susceptible to cost overruns.
Construction Costs for Nuclear Power Plants Are Projected to Increase According to companies who are developing new nuclear power plants, the overall cost (including finance and escalation expenses) will be between $6 billion and $9 billion for each 1,100 MW facility, or between $5,500/kW and $8,100/kW.
Hydroelectricity plant construction can cost up to Rs 7-9 crore per MW, as opposed to Rs 4.5–5 crore and Rs 3.5–4 crore for solar and thermal electricity, respectively. Solar plants can be operational in 1.5–2 years, however hydroelectricity projects might take up to eight years to complete, which is twice as long as thermal projects.
Low fuel prices and no carbon dioxide emissions are advantages of nuclear power. There are no fuel expenditures or air pollutants with solar and wind energy. The price of petrol is one factor, but every technology has associated costs. Nuclear, geothermal, and hydropower all require large construction budgets.
For every kilowatt of capacity, advanced nuclear reactors are anticipated to cost $5,366. That implies that, ignoring financing expenses, the construction of a massive 1-gigawatt reactor would cost about $5.4 billion. A brand-new wind farm, however, only costs $1,980 per kilowatt.
The project is currently two years behind schedule and is projected to cost between £25-26 billion, which is 50% higher than the initial 2016 estimate. It will reportedly be put into operation in June 2027 and have a 60-year expected lifespan.
Actual expenses were 15.3 billion pounds by the end of 2021, minus interim interests of 835 million euros ($914 million), it stated. According to EDF, “a new comprehensive evaluation is ongoing and is anticipated to be completed by summer 2022. It will update the costs and schedule estimates provided in January 2021.”
The cost of the plant, site acquisition (unless a rent is paid, in which case this is an operating cost), grid connection (although in some European nations, the utility has borne the cost), and initial finance charges are all included in the capital cost (not repayment costs). The price of constructing a coal power plant. In actuality, without financing charges, the estimated cost of constructing a new coal plant has already surpassed $3,500 per kW, and it is still anticipated to rise. Incorporating finance costs would result in a cost of well over $2 billion for a new 600 MW coal plant.
On the other hand, the expenses associated with building the plant itself account for a significant portion (between 60 and 80 percent) of the electricity prices for nuclear power. Thus, the price of their electricity is significantly influenced by the expenditures associated with building nuclear plants.
According to the International Renewable Energy Agency, 62% of the wind, solar, and other renewables that went online in 2020 were less expensive than the cheapest new fossil fuel (IRENA). The equivalent share for 2019 is double that here.
The average cost of producing hydropower in the UK is 0.85 cents per kilowatt-hour (kWh). This is almost equal to the costs of using nuclear power at 50%, fossil fuels at 40%, and natural gas at 25%.
These dams can take decades to construct, cost billions of dollars, and typically wind up costing 90% more than originally estimated. For instance, the Itaipu Dam, which was constructed in the 1980s between Brazil and Paraguay, cost $20 billion, took 18 years to complete, and produces 20% less electricity than expected.
If a generator that generates 1 MW of power were to run continuously for an entire year (8,765 hours), it would generate 8,765 MWh of energy. To put it into perspective, an average Canadian family house uses about seven MWh annually; therefore, in a perfect world, a 1 MW plant could power 1,200 homes.
How about this for those who want more power: A gigawatt is equal to 1.3 million horsepower. But here's a more useful metric: 750,000 houses can be powered by one gigawatt of energy.
Nuclear power facilities
Due to the requirement for specialized materials, sophisticated safety features, and backup control systems, nuclear power station construction costs are often much higher than those of coal- or gas-fired reactors.
Site preparation, engineering, manufacture, construction, commissioning, and financing are all capital expenses. Costs associated with fuel (from uranium mine to fuel production), maintenance, decommissioning, and waste disposal are included in operating costs.
This century-old utility business model is based on the core tenet that utilities make money by investing in the infrastructure, such as the pipes and wires that supply energy services to customers.
The British government approved the Sizewell C nuclear power station, to be built by France's EDF and China's CGN.
They have dug two enormous tunnels that extend two miles into the Bristol Channel. To cool the two nuclear reactors, 120,000 liters of water will pour in quickly and exit out a third tube each second. Construction took five years instead of the ten years EDF Energy predicted in 2016. Has it completed even half the task?
Of all power producing units, hydroelectric power plants require the least amount of maintenance. Hydroelectric power facilities not only offer cheap operating costs, but also low maintenance expenses.
A major nuclear unit may be constructed in five to seven years, according to the Nuclear Energy Agency (NEA). Once the nuclear power plant is constructed, the electric company tests it to check if it functions properly. If it passes the test, the power plant is then ready for use.
With a profit of 689 million British pounds in 2022, SSE outperformed the other major energy suppliers in the country in terms of energy generation. With a profit of 372 million pounds, Scottish Power had the second-highest profit in the sector that year.
Nuclear power plants were particularly susceptible to this change in market prices due to their high fixed costs, and by 2002 British Energy was unable to pay its obligations. After years of reorganization and a government rescue, British Energy's assets were eventually sold to EDF in France.
Cost of constructing a fossil fuel power plant
In actuality, without financing charges, the estimated cost of constructing a new coal plant has already surpassed $3,500 per kW, and it is still anticipated to rise. Incorporating finance costs would result in a cost of well over $2 billion for a new 600 MW coal plant.
Our reliance on foreign fossil fuels is reduced with each new wind turbine. Renewable energy in the UK has a lot of promise. The fact that green energy is now the most affordable means that it benefits both the environment and your wallet when it comes from a wind or solar farm close to you.
