Google Inc. and Citigroup Inc. are investing an additional $204 million to finance another phase of a California wind farm. The companies said that each will invest $102 million in Alta V, a 168-MW project. This is in addition to the combined $110 million in financing that the companies said they would put into the Alta Wind Energy Centre wind farm in California’s Tehachapi Mountains. In total, Alta will have a capacity of 1,550 MW, or enough to power 450,000 homes. This is nearly twice as much as the largest operating wind energy installation in the US.
Google has been investing hundreds of millions in wind energy as it seeks reliable new ways to power its massive data centres. The latest financing of the Alta farm brings the search engine’s total clean energy investments close to $780 million.
Google has also invested in solar energy. The company recently invested $280 million in partnership with SolarCity and has now entered the residential solar industry with its largest investment into the renewable energy industry.
