The smart grid system of the Santa Rita Jail integrates all of its on-site generation and advanced energy storage systems. It can power 100 percent of the jail's electrical needs during daylight hours.

The Santa Rita Jail is the first in the country to build its own all-inclusive smart grid. Located in Alameda County, the jail is the third-largest facility of its kind in California and the fifth-largest in the nation.

Several energy efficiency and renewable energy projects have been implemented since 2002, including solar photovoltaic panels and wind turbines, a fuel cell cogeneration plant, an advanced energy storage system, and a 3,600 million British thermal units (BTU) solar hot water system.
