A new data center in the United States is generating electricity for its servers entirely from renewable sources, converting biogas from a sewage treatment plant into electricity and water. Siemens implemented the pilot project, which recently went into operation, together with Microsoft and FuelCell Energy. The data center is not connected to the public power grid. Siemens developed and installed intelligent control and monitoring technology for the plant as well as energy management software so that the servers can be reliably supplied with electricity at all times. The partners intend to demonstrate that using intelligent hardware and software, even critical installations such as data centers can be reliably operated with alternative energy sources.
