Taiwan Mandates Environmental Reviews for Floating Solar Farms

New Regulations to Address Environmental Impact and End-of-Life Concerns for Renewable Energy Projects

Taiwan is set to implement mandatory environmental impact assessments for floating solar power projects, signaling a significant step towards more sustainable renewable energy development. The Ministry of Environment is currently developing the regulatory framework, which will specify the project sizes that necessitate such reviews. These details are expected to be finalized within the next one to two months.

While Taiwan aims to be the first nation to introduce specific environmental regulations for floating solar installations, the Minister of Environment, Peng Chi-ming (彭啓明), addressed existing concerns regarding the environmental impact of current projects. He stated that contractors have exclusively used water for cleaning solar panels, and comprehensive water quality tests conducted at various points, including water purification plants, have shown no discernible changes compared to historical data. Furthermore, stress tests involving the submersion and dissolution of panels indicated no significant adverse effects on water quality.

Lawmakers are urging swift action on these new regulations. Chang Chi-kai (張啓楷), a legislator, has called for the prompt release of the draft regulations. He also emphasized the need to review floating solar projects that sustained damage during recent typhoons.

In parallel, discussions are underway regarding the responsible disposal of solar panels. In response to legislative inquiries about the costs associated with solar panel disposal, Peng Chi-ming expressed optimism about the future development of circular economy principles for panel design. Legislators are pressing for concrete plans and cost estimates for disposal methods.

A recent report from the Control Yuan highlighted several challenges in Taiwan's solar energy sector, including issues with project proposal reviews, regulatory inconsistencies, external interference, and a lack of integrated land-use planning. The report cautioned that these shortcomings could potentially affect Taiwan's export competitiveness, foreign investment, food security, and the long-term viability of its solar energy industry. The Control Yuan has recommended that the Cabinet and the Ministry of Justice address these concerns, and has also called for investigations into the progress of policies aimed at integrating fishery and electricity generation.
