Wisconsin utility aims for 5% of its electricity supply from renewable sources by 2011

Milwaukee-based We Energies has signed contracts with private investors that are erecting single wind turbines in four towns in rural Wisconsin. The structures, expected to be built by 2007, measure 400 feet with a wingspan around 270 feet. Each unit can generate 1.65MW to 2.5MW, enough to meet the electricity needs of up to 1,000 homes. Each windmill costs about $2.5 million and has a life expectancy of up to 30 years.

A Wisconsin mandate insists that 2.2% of utilities’ portfolios be renewable by 2011. By that date, We Energies hopes to have 5% of its electricity supply come principally from wind power.
