GPA to replace streetlights with LED, starting in the South


Guam – As part of their cost saving initiative, the Guam Power Authority will begin the replacement of  high pressure sodium (HPS) streetlight fixtures with LED streetlight fixtures, starting with the Southern Villages.

GPA continues to improve energy efficiency and reduce operating and maintenance costs by upgrading the technology of existing streetlights from high pressure sodium (HPS) to LED streetlights.

Once completed, the LED streetlight replacement program is expected to save
on fuel expenses by nearly $1 million annually and reduce annual maintenance costs by
approximately $400,000. GPA has already changed out approximately 6,000 of the 16,000
public streetlights.

“GPA Crews will start the replacement of existing HPS lights within the seven southern
villages of Agat, Santa Rita, Umatac, Malesso, Inarajan, Talofofo and Yona,” stated Melinda
C. Mafnas, P.E., Assistant General Manager of Operations.

Motorists traversing within these areas are cautioned to be aware of line crews working
alongside utility easements and crossing streets to replace lighting fixtures.

“Crews will prioritize lighting along main routes and secondary roadways,” remarked
Mafnas, “GPA will complete the LED streetlight replacement program in FY2020.”
