Taiwan Inaugurates Largest Offshore Solar Plant of 373 MWac in Taiwan, Reinforcing Sustainability Goals and Contributing to CO₂ Reduction in the Country
A new offshore solar plant was recently inaugurated in Changhua County, Taiwan. The renewable energy company Hexa Renewables launched this innovative project, which represents a milestone in the advancement of clean energy.
The project has an impressive capacity of 373 MWac, enough to provide power to about 74,000 households in Taiwan.
Project Structure of the Largest Offshore Solar Plant in the World
The installation by Hexa Renewables is based on an initial project launched in 2020, which already had a capacity of 181 MWac.

Solar panels at sea can generate up to 12% more energy than land-based plants, study finds: Researchers from Taiwan discovered that offshore solar panels take advantage of the natural cooling of water to increase electrical efficiency, reduce heat losses, and expand renewable energy production in regions with limited available land space.
-
The era of solar panels attached to roofs is beginning to change with transparent glass that generates energy while keeping the view unobstructed, and perovskite photovoltaic windows already tested in offices in Japan promise to transform entire facades into invisible power plants without blocking light or altering the appearance of buildings.
-
The era of silicon alone in solar energy comes to an end with the arrival of perovskite, a material that captures a broader light spectrum, is applied as a thin film, and, together with silicon, reaches a theoretical limit of 45% efficiency in tandem modules.

Fernando de Noronha begins unprecedented energy transformation with a R$ 350 million solar plant that promises to replace diesel generation and change the island’s sustainable future by 2027.
The company continued the expansion in partnership with the government of Taiwan, adding another 192 MWac of power generation, totaling 373 MWac in the second phase of the project.
The company emphasizes that this revolutionary project represents a significant step forward in sustainable energy, maximizing the potential for solar energy in maritime areas.
With expansive infrastructure and cutting-edge technology, the installation aims to redefine standards and encourage the development of cleaner and more efficient energy solutions, promoting a large-scale ecological transition.

Environmental Impact and Contribution to Decarbonization Goals
In addition to being the largest offshore solar plant in the world, the project also plays a crucial role in advancing Taiwan’s environmental goals.
The plant will help the country progress toward its goal of net-zero emissions by 2050 and 20 GW of renewable energy capacity by 2025. The project is estimated to offset 136,000 tons of CO₂ annually, benefiting the local community and the environment.
Offshore Renewable Energy: A Global Trend
The installation of offshore solar and wind plants is becoming increasingly common as countries seek sustainable alternatives to replace fossil fuels.
Although these technologies have a relatively slower energy conversion rate, the reduced energy costs and positive environmental impacts make them appealing to governments and companies.
- Advantages of Offshore Plants:
- Utilization of spaces away from the mainland, reducing competition with other land use activities, such as agriculture.
- Greater energy generation potential due to strong winds and wide solar exposure in offshore areas.
- Challenges and Opportunities:
- Need for the development of specific technologies to endure offshore conditions, including corrosion resistance.
- High initial investments, excluding government subsidies and partnerships with infrastructure funds.
International Partnership and Innovation
In collaboration with the global infrastructure fund I Squared Capital, Hexa Renewables has paved the way for innovation in floating solar energy.
This project serves as a model for other nations and companies, such as the Dutch SolarDuck, which also recently launched a pilot project for a floating offshore solar plant at the OranjeWind wind farm.
The expansion of offshore solar and wind plants marks a new chapter in the renewable energy sector. Initiatives like Hexa Renewables in Taiwan showcase the potential to transform the global energy matrix and achieve clean and sustainable production.
