Yes, it is a state. A unique state. You do hear about Rhode Island in the news, any time there's a mafia arrest, or large-scale world disaster, like a fire out West, which will invariably be mentioned in terms of number of Rhode Islands affected.
Existing types of fossil plants have a capital cost about $1-2 Billion/GW and new nuclear plants are estimated to cost about $2-5 Billion/GW, depending on the laws of the country in which the plant is built.his translates into an average of about $25,000 per Megawatt-hour and $25 Million per Gigawatt-hour. A storage plant that needs to store 26 Gigawatt-hours (just 1 day's power supply) would thus cost about 650 Million dollars to build (estimated range from $260 Million to $1.1 Billion dollars).
Still, even as an optimistic estimate, it seems to indicate that nuclear could be having trouble keeping up with the rest of the industry. Wind, although intermittent, costs $1,300 a kilowatt. Flow batteries for storing wind power sell for $4,000 a kilowatt. Compressed air can cost $1,000 per kilowatt.Conceivably, wind and storage together hover just under the $6,000 kilowatt benchmark for nuclear. A home solar installation costs $6,000 a watt after incentives and far less for utility-scale projects.eanwhile, Mark Cooper, from the University of Vermont Law School, said earlier this year that the overnight cost might be in the $7,000-to-$8,000 per kilowatt range, with the all-in cost of a 2-gigawatt nuclear plant including financing running around $20 billion to $25 billion -- in other words, $10 or more per watt.
