US groups look to block $10bn SunZia grid link

US tribal and environmental groups have launched legal action to stop Pattern Energy building its $10bn SunZia transmission link between Arizona and New Mexico.

On 17th January, the Tohono O’odham Nation, San Carlos Apache Reservation, the Center for Biological Diversity and Archaeology Southwest filed a lawsuit in Tucson, Arizona, demanding that work on the project should stop due to the impact on a valley in the south of the US state.
