One of Tesla''s earliest microgrid projects with Powerpacks was deployed in American Samoa and now the company deployed two bigger systems in order to help the country of Samoa transition
The 1.4-megawatt PV and 6-megawatt-hour storage system developed by SolarCity can power the entire island for 3 days without sunlight and fully recharge in seven hours, ending the threat of fuel shortages, power rationing, and outages.
Six megawatt-hours of battery storage and load balancing systems enable the microgrid to store excess energy for deployment when the sun isn''t shining.[3] As a result, the island can stay powered for three full days with no sunlight.
The island nation of Samoa is continuing its effort to convert from diesel-reliant powerplants to 100% renewable energy with the help of Tesla''s scalable Powerpack battery storage solution.
The American Samoa Power Authority (ASPA) is the territory''s public utility and provides electricity, water, wastewater, and solid waste services to over 12,000 customers. The energy policy landscape in American Samoa constitutes a blend of multilateral agreements,

The island of Ta''u in American Samoa, located more than 4,000 miles from the West Coast of the United States, now hosts a solar power and battery storage-enabled microgrid that can supply nearly 100 percent of the island''s power needs from renewable energy.
The battery system can fully recharge in seven hours. The new solar+storage system also helps reduce air pollution, lowers the island''s contribution to global climate change, and helps meet its goal to be completely free of fossil fuels.

The stability and affordability of power from the new Ta''u microgrid, operated by American Samoa Power Authority, provides energy independence for the nearly 600 residents of Ta''u. The battery system also allows the island to use stored solar energy at night, meaning renewable energy is available for use around the clock.
In a statement to the Samoan Observer, Samoa Prime Minister Tuilaepa Sa’ilele Malielegaoi noted that the utilization of Tesla’s battery storage system has helped the country provide additional stability to its power grid.
The American Samoa Shipyard Services Authority is a key player in American Samoa’s energy sector. Shipyard facilities support local shipping and fishing fleets and provide critical services to ASPA tanks and port infrastructure.
Although energy burdens pose a real challenge in American Samoa, the territory is working to advance energy justice. For example, the Territorial Energy Office provides home energy efficiency programs to help reduce energy costs for low-income households.
American Samoa plans to make these data available to the public, to students of the Finafinau Group (an island community-service project focused on environmental conservation and resilience), and to all other interested parties for science projects and related activities (American Samoa Governor’s Office 2023a).
This report is available at no cost from the National Renewable Energy Laboratory at American Samoa has also instituted a number of rules, regulations, and informal goals to help codify its climate and energy objectives.
American Samoa’s energy sector relies almost entirely on imported fossil fuels, although renewables represent a small but growing power system contribution. The territory possesses substantial solar energy resources, as well as wind and biomass resource potential.
