The average household in Massachusetts uses about 630 kilowatts of electricity a month, according to the most recent US government data. With National Gridâs new winter rate of 24.24 cents per kilowatt-hour, a typical monthly bill would run slightly more than $150. A National Grid spokesman, Jake Navarro, said that two-thirds of the cost comes from the purchase of electricity from power plants, compared to just over half last winter.
Capital costs. A kilowatt is a unit of electrical power capacity. According to a U.S. Energy Information Administration, or EIA, report published in April 2013, the cost of building a utility-gradeâgreater than 150 MW (megawatt)âsolar power plant was $3,873 per KW (kilowatt).A 1KW power plant generates one kilowatt hour of electricity if it runs at 100% capacity for an hour.n comparison, cleaner coal-fired power plants cost upwards of $4,000 per KW, and advanced natural-gas fired plants cost $2,000 per KW. Nuclear plants are the most expensive to build at $5,500 per KW. A wind power plant, another renewable source, costs $2,200 per KW to build.
