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 starting levelized cost was 8.2 cents per kilowatt hour that reflects installation costs of $2,000 per kilowatt of capacity and is based on information from EIA and the Office of Energy Efficiency and Renewable Energy at the Department of Energy.omparison 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.
