A Small Island in the South Pacific Ocean Leaping Forward
as the Representative of Global ESS Business
Guam is a small island self-supporting its own energy because of its location far from the mainland.
Well known as a vacation destination, this island recently came into the limelight as the global center of the microgrid market.
Particularly, there has been an active movement to distribute and expand ESS – the core technology of microgrid.
The Paris Agreement of the United Nations Framework Convention on Climate Change has raised global interest
towards renewable energy-based, self-sustainable microgrids, in which ESS plays a critical role.
As an island 3,000 miles away from the nearest main landmass,
Guam is positioned to become a prime example of the growing global microgrid market for independent electric utilities.
Moreover, Guam also serves as a strategic base expand into various markets;
it neighbors Hawaii and the U.S. mainland to the east, Australia to the south, and Southeast Asian countries to the west.
LG CNS Exports One of
the World’s Largest Scale ESS to Guam
LG CNS, ranked as No. 1 in Asia and No. 7 globally in the latest Utility-Scale ESS Integrators Leaderboard by Navigant Research,
was successfully awarded a $43 million contract by the Guam Power Authority (GPA). LG CNS will delivers, operates and maintains
two Energy Storage Systems (ESS) which can deliver 40 megawatts (MW) of power output.
This project will reduce the intermittent power outages Guam is experiencing due to increasing net metering penetration and
utility scale renewable projects. One plan is to call for a 24 MW ESS for frequency regulation to be located at a substation in
the village of Agana. The other one is to install 16 MW ESS for renewable integration at the substation in the village of
Talofofo, which is connected to an existing solar farm.
Better Life in Guam with Renewable Energy
Renewable energy such as solar photovoltaic plants provides intermittent power output due to Guam’s varying weather conditions.
The higher the rate of renewable penetrations, the more grid issues will be introduced.
However, by controlling the ramp rate, ESS technology can be the solution for these issues.
As the renewable market continues to grow and more and more countries and communities adopt renewable energy goals,
the global demand for renewable integration ESS will increase.
LG’s Guam ESS Project is the collaborated result of LG CNS’ own Energy Management System (EMS) and LG Chem lithium-ion batteries.
This project aims to provide frequency regulation and solar photovoltaic (PV) ramp rate control.
The project includes 25-year operations and maintenance agreement.
