Summary of the Renewables Readiness Assessment for Antigua and Barbuda

Core Content

The Renewables Readiness Assessment (RRA) for Antigua and Barbuda outlines a strategic pathway for increasing the share of renewable energy in the country's energy mix. The assessment was conducted in collaboration with the International Renewable Energy Agency (IRENA) and is a country-led initiative aimed at identifying policy, regulatory, and institutional actions to accelerate renewable energy deployment.

Antigua and Barbuda is a small island nation with a population of 89,985 and a land area of 443 km². It is highly dependent on imported fossil fuels, particularly heavy fuel oil (HFO), for its energy supply. This dependency leads to volatile and high energy costs, and the country has significant potential for solar, wind, and bioenergy. The RRA highlights the need to leverage these resources to reduce reliance on imported fuels, lower costs, and enhance energy security.

Main Points

1. Energy Sector Overview

• Energy Resources: Antigua and Barbuda has considerable solar, wind, and bioenergy potential. However, it is almost entirely dependent on imported fossil fuels.
• Energy Imports: In 2014, the country imported 192,788 tonnes of oil equivalent, with HFO being the largest component for the power sector.
• Electricity Supply: The electricity sector is managed by the Antigua Public Utilities Authority (APUA), a government-owned vertically integrated corporation. APUA supplies nearly all of the electricity, with 80-90% coming from a locally owned independent power producer (IPP).
• Electricity Consumption: The country's peak electricity demand is 51 MW, with an expected increase to 55 MW by 2025. In 2015, renewables accounted for 1.6% of peak electricity demand.
• Desalination: The drinking water sector is heavily reliant on seawater desalination, consuming 10% of total electricity on Antigua. No renewable sources are currently used for desalination.

2. Renewable Energy Deployment

• Progress to Date: Antigua and Barbuda has already exceeded its 2015 renewable energy target, with renewables approaching 20% of peak electricity demand.
• Renewable Potential: The country has the potential to integrate 37.5 MW of solar photovoltaic (PV) capacity, which would account for 75% of peak electricity demand.
• Government Commitment: The government has enacted the Renewable Energy Act (2015), removed duties on renewable technologies, and secured soft loans from the Abu Dhabi Fund for Development.
• National Energy Policy (NEP 2011): This policy sets out the country's vision for sustainable energy, including targets for renewable energy development.

3. Key Challenges and Recommendations

Key Challenges:

• Financial Barriers: High costs of importing fossil fuels and limited access to financing for renewable projects.
• Technological Barriers: Limited infrastructure and expertise for integrating renewable energy into the grid.
• Policy and Regulatory Barriers: Outdated and complex policies for grid interconnection and energy pricing.
• Social and Environmental Barriers: Public awareness and understanding of renewable energy benefits and challenges.

Key Recommendations:

1. Develop an Action Plan: To scale up renewable energy deployment and meet INDC targets, considering technical, economic, financial, policy, regulatory, institutional, social, and environmental factors.
2. Review and Rationalise Policies and Tariffs: For grid interconnection with distributed renewables, ensuring a fair and transparent regulatory framework.
3. Launch a Public Awareness Campaign: To educate citizens about the costs and benefits of renewables and encourage sustainable behavior.
4. Create a National Strategy for Bioenergy and Waste Management: To explore the commercial potential of bioenergy, including fuelwood, charcoal, and biodiesel.
5. Establish an Independent Energy Commission: To regulate the electricity supply market, including pricing, quality of service, and grid interconnection.
6. Standardise Renewable Energy PPAs: To provide a level playing field for investors and reduce administrative burdens.

Key Information

• Renewable Energy Potential: Antigua and Barbuda has high potential for solar, wind, and bioenergy.
• Current Renewable Share: Renewables currently cover 1.6% of peak electricity demand (April 2015).
• Desalination Impact: Desalination accounts for 10% of electricity consumption on Antigua and is expected to grow.
• Petrocaribe Initiative: While it has helped reduce energy costs, it has also increased long-term debt and dependence on fossil fuels.
• IRENA Support: IRENA provided technical support and facilitated stakeholder consultations, helping to identify key actions for renewable energy deployment.
• 2025 Target: The RRA recommends a 75% grid-based renewable capacity target by 2025, supported by a roadmap and initial milestones.

Conclusion

The RRA serves as a comprehensive guide for Antigua and Barbuda to transition towards a more sustainable and resilient energy system. It highlights the importance of policy reform, regulatory support, public engagement, and investment in renewable technologies to achieve the country's energy and climate goals. The government is committed to this transition and is working closely with IRENA and other international partners to implement the recommended actions.
