Economics of nuclear power plants
Nuclear power construction costs have varied significantly across the world and over time. Rapid increases in costs occurred during the 1970s, especially in the United States. Recent[when?] cost trends in countries such as Japan and Korea have been very different, including periods of stability and decline in construction costs.
New nuclear power plants typically have high capital expenditure for building plants. Fuel, operational, and maintenance costs are relatively small components of the total 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. Additionally, measures to mitigate climate change such as a carbon tax or carbon emissions trading, favor the economics of nuclear power over fossil fuel power. Nuclear power is cost competitive with the renewable generation when the capital cost is between $2000 and $3000/kW.
The economics of nuclear power are debated. Some opponents of nuclear power cite cost as the main challenge for the technology. Ian Lowe has also challenged the economics of nuclear power. Nuclear supporters point to the historical success of nuclear power across the world, and they call for new reactors in their own countries, including proposed new but largely uncommercialized designs, as a source of new power.
The Intergovernmental Panel on Climate Change (IPCC) while endorsing nuclear technology as a low carbon, mature energy source (addressing greenhouse gas emissions), notes that nuclear's share of global generation has been in decline for over 30 years, listing barriers such as operational risks, uranium mining risks, financial and regulatory risks, unresolved waste management issues, nuclear weapon proliferation concerns, and adverse public opinion.
Solar power has very low capacity factors compared to nuclear, and solar power can only achieve so much market penetration before (expensive) energy storage and transmission become necessary. This is because nuclear power "requires less maintenance and is designed to operate for longer stretches before refueling" while solar power is in a constant state of refueling and is limited by a lack of fuel that requires a backup power source that works on a larger scale.
The price of new plants in China is lower than in the Western world.
In the United States, nuclear power faces competition from the low natural gas prices in North America. Former Exelon CEO John Rowe said in 2012 that new nuclear plants in the United States "don't make any sense right now" and won't be economic as long as the natural gas surplus persists.
In 2016, the Governor of New York, Andrew Cuomo, directed the New York Public Service Commission to consider ratepayer-financed subsidies similar to those for renewable sources to keep nuclear power stations (which accounted for one third of the state's generation, and half of its emissions-free generation) profitable in the competition against natural gas plants, which have replaced nuclear plants when they closed in other states.
