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 high cost of upgrading 40-year-old nuclear reactors is confronting Xcel Energy again. Investments in the Prairie Island nuclear power plant in Red Wing, Minn., are projected to cost more than expected â $487 million by 2020, with more spending needed in the next decade. Itâs not a replay of cost overruns at Xcelâs other reactor in Monticello, Minn.
