The pattern of and in is shaped by its location, a remote island. Almost all energy is reliant on imports of for use in transport and electricity. Guam has no domestic production of such as oil, natural gas or coal. Its economy is dependent on the import of gasoline and for transport and for electricity. One third of electricity produced is used in commercial settings including the leading industry of touri. [pdf]

In Guam, the consumption of energy is heavily influenced by its remote location. Almost all energy is reliant on imports of petroleum products for use in transport and electricity. Guam does not have any domestic production of conventional fuels such as oil, natural gas, or coal.
Guam, Micronesia. Image: flickr user Jonathan Miske. Engie has been hired by Guam’s state electricity utility to build two solar-plus-storage plants with a combined capacity of 50MWp/300MWh on the Micronesian island.
Guam has a rated generating capacity of 560 MW, more than twice its historical highest load. This power is supplied by several plants burning residual fuel oil operated for the Guam Power Authority by independent power providers. In 2015, electricity in Guam cost 2.5 times as much as on the U.S. mainland.
Renewable electricity here is the sum of hydropower, wind, solar, geothermal, modern biomass and wave and tidal power. Traditional biomass – the burning of charcoal, crop waste, and other organic matter – is not included. This can be an important source in lower-income settings. Guam: How much of the country’s electricity comes from nuclear power?
Guam has announced plans for several large solar farms. The island has adopted a renewables policy that requires the reduction of fossil fuel consumption by 2020 to 20% less than the rate in 2010. Another requirement is for 5% of electricity in 2015 to be from renewables, increasing to 25% by 2035. A net metering program began in 2009.
Traditional biomass – the burning of charcoal, crop waste, and other organic matter – is not included. This can be an important source in lower-income settings. Guam: How much of the country’s electricity comes from nuclear power? Nuclear power – alongside renewables – is a low-carbon source of electricity.

In Guam, the consumption of energy is heavily influenced by its remote location. Almost all energy is reliant on imports of petroleum products for use in transport and electricity. Guam does not have any domestic production of conventional fuels such as oil, natural gas, or coal.
With no indigenous fossil energy resources, Guam is reliant on imported fuel for their energy and transportation needs, with most of the imported fuel coming from Asia. The Guam Power Authority (GPA) is a public-power utility and autonomous agency of the government of Guam.
Due to geographic isolation and lack of local energy supply, Guam depends on imported fossil fuels to meet all its energy needs. Liquid fuel supply chains are vulnerable to physical, political, and cybersecurity threats as well as market conditions, which can result in supply uncertainty, price volatility, and high energy costs.
The U.S. Navy and Air Force have significant land holdings and operations that impact both the economy and energy consumption of the island. As previously noted, the U.S. Navy alone is the island’s largest energy consumer, representing 20% of electricity sales (The Bureau of Statistics and Plans Guam 2022).
Transmission and distribution losses on Guam are estimated to be 4.9% according to the U.S. Department of Energy (2020). This is comparable to the United States as a whole (at 5%) (U.S. Energy Information Administration n.d.-b).
Introduction This report summarizes the currently available data on Guam’s energy sector as of December 2023. It describes primary energy consumption, end uses, energy production, relevant policies, and key challenges, including details on the electric power and transportation sectors.
