An Island Nation Races towards a Zero-Carbon Future

Grenada, nestled in the Caribbean Sea, is blessed with some of the world's most abundant solar resources — yet for years, the country's electricity has depended almost entirely on imported diesel. Under the framework of the International Zero-Carbon Island Cooperation Initiative unveiled at the China Pavilion of the 29th session of the Conference of the Parties to the United Nations Framework Convention on Climate Change (COP29), related parties from Yantai City in China's Shandong Province and Grenada signed a Memorandum of Understanding in early 2025 on advancing cooperation on zero-carbon islands. The two sides are cooperating on new power grid systems, scientific and technological training, water resource management, and low-carbon tourism, promoting the energy transition of island regions, scaling up the use and integration of renewable energy, strengthening technical capacities and personnel exchange, implementing seawater desalination and resource recovery, and developing green and low-carbon tourism. These joint efforts, in turn, support sustainable low-carbon development on island communities.

With the widespread implementation of advanced, reliable photovoltaic storage systems tailored to local natural conditions, pilot-program residents in Grenada's capital, St. George's, have seen their electricity bills drop significantly. 

Key Challenges

Grenada faces chronic electricity shortage, and its high-cost, high-emission energy structure has long constrained its economic growth. Simultaneously, demands on the durability and adaptability of energy infrastructure are forcibly stringent due to the island's humid climate, rising sea levels and increasingly frequent episodes of extreme weather.

Solution Pathways

A highly adaptable photovoltaic storage system has been designed and engineered for the island, using highly corrosion-resistant, high-stability solar panels and integrating electricity generation, supply, and storage into a seamless, reliable closed-loop system at reduced costs for end-users. Comprehensive training programs have also been implemented in order to address end-to-end operations and equipment maintenance. Furthermore, such systems and related services stand for an integrated solution for the green, low-carbon and sustainable development of the island nation.

Practical Benefits for Local Communities

Three such pilot systems generate a daily average of more than 50 kWh electricity per day, cutting both electricity bills and carbon emissions. The island government is expected to scale the installation program nationwide, targeting an approximately 5,000 low-income households and helping residents reduce their reliance on diesel for electricity.
