About Us


Who We Are

The Guam Energy Office is a small line agency within the Executive Branch of the Government of Guam.  Established since 1974, the Guam Energy Office continues to exist by Executive Orders and with mostly federal dollars from U.S. Department of Energy to operate and implement grant activities including addressing local initiatives.  With the Remaining Petroleum Violation Escrow distributions, the Guam Energy Office built its own office building authorized by U.S. Department of Energy in year 2000.  The office building is a small-scale demonstration facility featuring energy efficient measures such as lighting, Energy Star® office equipment and appliances, daylighting, solar applications, net metering, and roof/wall insulations.

Plug-In Electric Vehicle Rebate Program

The Plug-In Electric Vehicle (EV) Rebate Program is a local program for Guam Energy Office to adopt rules and regulations 180 days after the enactment of law and offer rebate for not more than 10% of the total base price of a qualified plug-in electric drive motor vehicle.  The amount of $300,000 was appropriated for the local program.  Funds continue to be available until fully expended.  In FY 2015, the Guam Energy Office established the regulations, developed the application forms to include proof of required documents, held public hearings to finalize regulations, and then worked with automotive dealerships to consider importing EVs to Guam.  The goal of this program is to reduce fuel consumption, reduce harmful emissions into the environment, and to stimulate Guam’s economy by assisting residents with rebates for the purchase of EVs.  Issuing rebates to residents started in FY 2016.




Weatherization Assistance Program

The Weatherization Assistance Program (WAP) is a federally funded annual program that helps reduce energy costs for eligible low-income households by improving the energy efficiency of their homes while ensuring their health and safety.  From replacement of refrigerators to installation of smoke detectors, this program is geared to eligible elderly, individuals with disabilities, and families with children.  WAP services are free to households meeting criteria based on household income and acceptable housing.  To qualify, the total household income shall not exceed maximum income as stated on chart.

GovGuam Line Agencies Energy Audit


The Guam Energy Office, through its contractor Taniguchi, Ruth, Makio Architects (TRMA), has completed the Government of Guam Line Agencies (GLA) Energy Audit Report for Phase I & II under the American Recovery and Reinvestment Act of 2009 State Energy Program.


The energy audits were completed for 15 agencies, consisting of 51 buildings, of which 49 were or will be retrofitted for energy conservation measures that will include lighting system, roof coating, HVAC improvements, plumbing and appliance systems.


Copies of the energy audit reports are available for download

Disclaimer: For purposes of determining savings, the energy audit report assumes air conditioning units and lighting are operating on a regular cycle during the day. If the air conditioning or lighting is not operating, the power bills will be lower than the “benchmark” assumed by the report. For example, prior to the retrofit, Guam Energy Office many times managed their usage and kept their lights off during the day – but the energy audit report assumes they would be on. The report benchmarks what it would be if the lights were operating and compares the savings by replacing with more efficient lighting, occupancy switches, and zoning.
