Guam Territory Energy Profile
Guam Quick Facts
•
Guam has no conventional energy resources and relies on petroleum products shipped in by tanker to
meet almost all its energy needs.
•
•
As of January 2012, Guam Power Authority prices averaged 27 cents per kilowatthour.
In 2011, the Public Utility Commission approved two Guam Power Authority contracts for the first
commercial wind and solar projects, which total 35 megawatts and are due to begin operation in 20142015; currently, the Navy and Air Force bases on Guam are installing solar arrays and water heaters in
living quarters and linking electricity generation from solar energy to the main grid to reduce fuel use.
•
Guam Power Authority is pursuing the potential for seawater air-conditioning, in which cold water drawn
from offshore chills seaside building air-conditioning systems.
•
Guam's Renewable Portfolio Goal calls for 5 percent of net electricity sales to come from renewable
energy resources by 2015 and 25 percent by 2035.

Analysis
Resources and Consumption
Guam is an island located in the North Pacific Ocean three quarters of the way from Hawaii to the Philippines.
With a land area of 209 square miles, Guam is approximately three times the size of Washington, D.C. Guam
has a tropical marine climate that is warm and humid with little seasonal temperature variation, a dry season
from January to June, and a rainy season from July to December. Guam has a population of about 173,000.
U.S. military spending is the main contributor to Guam's economy. Guam's tourist industry has grown over the
past 30 years to become the next largest income source.
The territory has no conventional energy resources and meets nearly all of its energy needs with petroleum
products shipped in by tanker. Per capita energy consumption in Guam is relatively low (148 million Btu in
2006), which is less than the U.S. average (335 million Btu). In 2006, Guam's energy intensity was 8,696 Btu
per dollar of gross domestic product (GDP) in 2000 dollars, about the same as the U.S. average. (Energy
intensity is measured as total primary energy consumption per dollar of GDP.)
Petroleum
Guam has no refineries and ships all of its petroleum products in through its only port, located in Apra. Jet fuel,
residual fuel oil, and distillate fuel oil are the main petroleum products shipped in.
Natural Gas
Guam does not produce or consume natural gas.
Coal, Electricity, and Renewables
Guam does not produce or consume coal. Electricity is provided by the Guam Power Authority and three
independent power producers -- Pruvient Energy Guam, Inc., Taiwan Electrical and Mechanical Engineering
Service, Inc., and Marianas Electric Corporation -- which operate petroleum power plants to meet electric
power demand in this U.S. territory. Guam has 550 megawatts of installed generating capacity to serve a peak
electric load of 280 megawatts.
Little renewable energy is currently consumed on the island beyond a few photovoltaic units used for cell
phone towers and remote weather stations, solar thermal units used for water heating, and a few small (less
than 5 kilowatts) wind generators operated by commercial and residential users. In 2008, Guam enacted a
renewable portfolio goal to have renewable sources provide 5 percent of net electricity sales by 2015 and 25
percent of net electricity sales by 2035. Additionally, any new base load electrical generation plant is required
to obtain 10 percent of its total generation capacity from alternative energy sources. The Guam Power
Authority has since released a notice of intent to acquire 80 megawatts of renewable energy generating
capacity by 2013.
Guam has very large wind resources (classes 6 and 7, measuring between 17.9 miles per hour and 26.6 miles
per hour at 50 meters above ground level) during the winter season (December, January, and February) in the
ocean area surrounding the island. Lower strength wind resources (up to class 4, measuring up to 16.8 miles
per hour) can also be found throughout the island and in the southern mountains in particular. Wind speeds
designated with a class of 3 or higher are suitable for most utility-scale wind turbine applications. However,
Guam has one of the highest risks of typhoon passage of any Pacific island, and a study of the costs and risks
of turbines specially engineered to resist typhoon-force winds needs to be carried out before optimal sites can
be identified.
