For reference, about 10,000 100-watt lightbulbs or 5,000 computer systems would be needed to draw 1 MW. Also, 1 MW is approximately 1360 horsepower. Modern high-power diesel-electric locomotives typically have a peak power of 3–5 MW, while a typical modern nuclear power plant produces on the order of 500–2000 MW peak output.
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m 2 ⋅s −3. [1] [2] [3] It is used to quantify the rate of energy transfer.
Certain onshore wind farms can reach capacity factors of over 60%, for example the 44 MW Eolo plant in Nicaragua had a net generation of 232.132 GWh in 2015, equivalent to a capacity factor of 60.2%, [7] while United States annual capacity factors from 2013 through 2016 range from 32.2% to 34.7%.

Natural gas power stations opened at a fast rate throughout the 2010s, quickly replacing aging, dirty, and economically unviable coal-fired power stations, but by the early 2020s new plants were mostly wind and solar with only Texas, Ohio and Pennsylvania continuing to open significant numbers of gas plants.
The proposed 20,000 MW Australia's Darwin Solar Park, for the Australia-Asia Power Link, would be slightly below the capacity of the Three Gorges Dam. [ 3 ] [ 4 ] The proposed Grand Inga Dam in the Democratic Republic of the Congo would surpass all existing power stations, including the Three Gorges Dam, if construction commences as planned.
The Koeberg Nuclear Power Station in South Africa has a rated capacity of 1860 megawatts. The coal-fired Ratcliffe-on-Soar Power Station in the UK has a rated capacity of 2 gigawatts. The Aswan Dam hydro-electric plant in Egypt has a capacity of 2.1 gigawatts. The Three Gorges Dam hydro-electric plant in China has a capacity of 22.5 gigawatts.
Lazard study assumes "60% debt at 8% interest rate and 40% equity at 12% cost" for its LCOE calculation but did not disclose their methodology or project portfolio used to calculate prices. [91] In the 2023 study Lazard explained their LCOE estimates for nuclear power are "based on the then-estimated costs of the Vogtle Plant and US-focused". [83]
