Unplugged Wind Farms Sit Unused as Drought Strains Grid

As a drought in Brazil strains hydroelectricity production, 48 wind farms stand idle because they’re not connected to the power grid.

State-run Chesf, a unit of Centrais Eletricas Brasileiras SA, is running behind by as much as 19 months on projects to build transmission lines to wind farms built by companies including Renova Energia SA and CPFL Energias Renovaveis SA. The farms, which could power 3 million homes, are part of a government plan to more than double energy from wind, biomass and small hydro-power plants by 2022, according to the government’s energy planning company, known as EPE.
