Byron Wind Turbines
In the mid-1990s, We Energies wanted to meet growing customer demand for renewable energy generated from sources such as the sun, wind, water and plant materials. To accomplish this, the Energy for Tomorrow® renewable energy program was launched in June of 1996.
Research showed that the Niagara Escarpment, a high ridge running through eastern Wisconsin, would be a favorable location for wind turbines. At a site near Byron, the average wind speeds were approximately 14 mph, the land was privately owned and accessible, power lines were nearby, and the location was away from the migratory routes of many birds.
