FAQS about Guam commercial solar power generation

Does Guam have a virtual power plant program?

Regulations are described in Guam Code § 8309. As per Guam Code § 8603, GPA must develop a Virtual Power Plant Program. The program would initially be capped at 20 MW and provide an alternative rooftop solar program to address the challenges of the Net Metering program. This program is currently under development.

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.

Does Guam use fossil energy?

3 Guam has no fossil energy resources and meets nearly all of its energy needs—including the fuel for generating most of its electricity—with imported petroleum products. 4, 5 However, Guam is increasing its use of renewable energy resources for electricity generation. 6, 7

Does Guam have electricity?

About four-fifths of Guam’s electricity generating capacity runs on fossil fuels and the rest is fueled by renewables. The Guam Power Authority (GPA), a public corporation overseen by the elected Consolidated Commission on Utilities (CCU) and regulated by the Guam Public Utilities Commission (PUC), provides all of Guam's electricity.

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 does electricity cost in Guam?

Electricity costs in Guam are almost double the U.S. national average, although somewhat lower than other islands in the Pacific. The average retail electricity cost in 2022 was nearly $0.35/kWh, inclusive of a fuel surcharge that can be adjusted every six months based on the market fuel price.

FAQS about How to calculate the reactive power of microgrid

Why does a microgrid have a reactive power balance?

In both the cases, the reactive power that flows through the microgrid has to be effectively controlled and compensated. In islanded operating condition, the microgrid has to maintain the reactive power balance independently due to the absence of an infinite bus.

Why does a microgrid need reactive power support?

In islanded operating condition, the microgrid has to maintain the reactive power balance independently due to the absence of an infinite bus. The firmly coupled generation and utilization along with the presence of non-dispatchable intermittent renewable power sources require reactive power support.

What are power quality problems in a microgrid?

Power quality problems in a microgrid are of a large variety such as voltage harmonics, voltage sags, voltage swells, voltage unbalance, current harmonics, reactive power compensation (RPC), current unbalance and circulation of neutral currents, impulse transients, and interruptions .

How can frequency be controlled in a microgrid?

The theoretical analysis indicates that the frequency can be controlled by the reactive power in a microgrid with resistive cables, while the frequency can be controlled via the active power in a microgrid with inductive cables.

How does a microgrid work?

The microgrid operates in two operating modes; grid connected (connected to the conventional grid to allow power exchange) and individual/islanded mode (independent of the conventional grid). The major elements of MG have DG units like PV and wind generators, storage devices, different loads, and power controllers.
