Does Antigua & Barbuda have a power system?

This is considering solar, wind, and storage, and not considering hydrogen. Includes hydrogen electrolyser, storage and fuel cell for power-to-hydrogen and hydrogen-to-power. The current power system of Antigua and Barbuda is highly dominated by fossil fuel generation, with only a 3.55% renewable energy share.

How do we estimate the energy load for Antigua and Barbuda?

To estimate the load for Antigua and Barbuda, data were needed on the energy production from the existing generators. APUA provided IRENA with data on the generation of each power plant for four consecutive years: 2016, 2017, 2018 and 2019. However, the data provided for 2019 (the most recent year) were monthly values and not hourly.

Which energy source is most dominant in Antigua and Barbuda?

From the figure, it is also clear that the HOMER optimisation has estimated solar energy to be the more dominant source of electricity in Antigua and Barbuda to serve most of the load. The dominance of solar PV in meeting most of the total load in this scenario is clearer when observing the installed capacity by technology in Figure 21.

What is the share of solar PV & wind in Antigua & Barbuda?

In the previous scenario, a larger share of generation was coming from solar PV, while with the deployment of EVs we see a more even share between solar PV and wind. Almost 50% of the total load of Antigua and Barbuda is being met by the solar arrays, while around 46% is covered by the wind turbines.

Can Antigua and Barbuda achieve a fully decarbonised power system?

As analysed in the roadmap, the deployment of solar PV and battery systems for the residential sector of Antigua and Barbuda will be an important element, as planned by the Government, for achieving a fully decarbonised power system by 2030.

Does Antigua & Barbuda have a solar system?

It is important to note that there is no battery storage system currently deployed in Antigua and Barbuda, hence the solar systems can only generate electricity during the day when sunlight is available. This makes it indispensable for the heavy fuel oil generators to cover the entire load during evening hours.
