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).
The unit nuclear power generation cost of 7.2 yen/kWh includes 1.9 yen/kWh in capital cost, 0.6 yen/kWh in fuel cost, 2.7 yen/kWh in operation and maintenance cost, 1.8 yen/kWh in backend cost and 0.3 yen/kWh in reactor decommissioning cost.
