6 FAQs about [Guam energy storage systems comparison]
Why is Guam reliant on imported fuel?
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.
What data is available on Guam's energy sector?
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.
How much energy does Guam use?
Conclusion Total energy consumption in Guam has been increasing over the past 12 years. In 2021, the island consumed 241 million gallons of imported fossil fuels. Of the total energy consumed on the island, less than 4% is supplied by carbon-free renewable energy.
How many Customer-Sited distributed energy resource systems are there in Guam?
Over 2,000 customer-sited distributed energy resource (DER) systems represent significant assets to Guam’s renewable energy (RE) generation. Nearly 22 MW of DER generation capacity accounted for 2.6% of total generation/sales and 23% of total RE generation/sales in 2021 (see Table 6).
Does Guam have a smart grid?
Guam Power Authority received a $16.7 million ARRA Smart Grid Initiative Grant from the Department of Energy to implement a comprehensive deployment of Smart Grid technologies. GPA floated bonds in FY 2010 to come up with the matching $16.7 million.This project is a transformational project to bring Guam's power grid into the 21st century.
Does Guam need to retire power plants?
Guam Power Authority is challenged by the need to retire power plants while reliably and affordably delivering power to its customers. The settlement of an EPA Clean Air Act violation requires GPA to retire older fossil-based generating plants while Renewable Portfolio Standards mandate a transition to carbon-free electricity.
