us installed wind turbine capacity was 11575 mw at end 2006 and 16907 mw at end 2007 for an increase of 5332 mw at a capital cost of about $ 9598 million i e the transmission cost adder is about 1902 9598 19 8 %arious big wind promoters maintain the cost of wind energy is competitive with other sources of energy as shown below this is hardly the case they often point to power purchase agreements ppas between wind turbine owners and utilities to sell at 5 to 6 c kwh as proof of market price parity
