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).
Comparison to Other Technology Costs. According to the EIA, the levelized cost of an advanced natural gas-fired combined cycle plant is 6.3 cents per kilowatt hour and that of an advanced coal-fired plant and nuclear plant are each 11.1 cents per kilowatt hour.hus, the total cost for wind power, including the hidden costs, averages 15.1 cents per kilowatt hour for natural-gas fired back-up and 19.2 cents per kilowatt-hour for coal-fired back-up.
