Environmental–Social Screening and Ecological Protection
To support the coexistence of aquaculture, solar PV development, local communities, and the surrounding ecosystem—and to reduce disputes related to site selection—HDRE applies the Environmental and Social Screening Framework for Solar PV Aquaculture Co-generation.
The framework is used during the site-selection stage to identify potential ecological and socio-economic impacts associated with PV development. Based on the issues identified, HDRE prepares appropriate mitigation and management measures for each project site.
The process consists of four main steps:：
| Issue Identification |
Environmental simulations are used to understand local conditions, and external consultants or environmental organisations are engaged to help identify potential environmental and social issues early in the process. |
| Soil and Water Assessment |
Water and soil quality are tested quarterly throughout the pre-construction, construction and post-construction phases to ensure that environmental conditions remain stable. |
| Ecological Survey |
Independent ecological consultants conduct surveys and monitoring across all stages. Their findings provide long-term tracking of potential ecological impacts and are published online for government, academic and industry reference. |
| Engineering Design |
Project site planning is aligned with aquaculture operations and nearby habitats of ecological value, reducing disturbance to the ecosystem while allowing aquaculture activities to continue. |
Three Strategic Directions for Sustainable Project Sites：
1. Biodiversity and Community Co-Prosperity
HDRE places strong emphasis on biodiversity conservation and community development. Ecological reserve areas are designated within project sites, and native species restoration is actively advanced.
At the community level, HDRE prioritizes local recruitment and supports cultural and community initiatives to create shared value.
By integrating high-density aquaculture practices with natural, organic materials, project sites are designed to enable aquaculture and the surrounding environment to coexist in a balanced and resilient manner.
(For further details, refer to the 2024 Sustainability Report: Section 4.3 Biodiversity and Section 6.1 Community Development.)
2.Local Industry Development and Talent Cultivation
HDRE adopts a vertically integrated approach to strengthen the local aquaculture value chain. Local talent is prioritized in hiring, and partnerships with universities introduce aquaculture internship programs to support talent development and technical knowledge transfer.
Standardized aquaculture procedures and knowledge management systems help shorten training cycles while creating pathways for young people to return to their hometowns. These efforts inject new energy into traditional aquaculture and support long-term rural revitalization.
3.Nature Risk and Ecological Management under the TNFD Framework
HDRE is committed to the goals outlined in its Biodiversity Policy. Guided by its core value of coexistence with nature, HDRE aims for no net loss in the near term and targets a net positive impact on biodiversity by 2050.
Ecological surveys and conservation measures continue across project sites, such as protecting waterfowl habitats and native mangrove areas at the Qigu Project Site, and advancing environmental education and ecological retention pond development at the Gukeng Project Site.
HDRE will further expand collaboration with the Tainan Salt Pan Wetland Restoration Alliance and support at least three years of wetland rehabilitation to safeguard migratory bird habitats and reinforce natural carbon sinks.
Moving forward, HDRE will broaden the application of biodiversity-friendly project site design, tailoring conservation measures to site-specific ecological conditions and strengthening its contribution to Taiwan’s biodiversity and energy transition.

Aquaculture Co-generation as a National Sustainability Strategy:
Aquaculture co-generation plays a vital role in advancing national sustainable development.
- Energy: Supports renewable energy targets and reduces carbon emissions.
- Society: Revitalizes fishing communities and creates local employment opportunities.
- Industry: Drives digital transformation in aquaculture, strengthening competitiveness while preserving local aquaculture heritage.
By moving beyond the traditional “single land use, single purpose” model, aquaculture co-generation unlocks diversified land value—balancing food security, energy production, and ecological conservation.

HD Renewable Energy develops its project sites guided by the principle of “growing with local communities and coexisting with nature.”
Through project development across Taiwan, we enhance land value without compromising ecological integrity, creating broader opportunities and a more diverse quality of life for local residents.
HD Renewable Energy remains committed to advancing environmental sustainability. We continue to follow ecological and environmental conservation principles and will minimize ecological impact in the development of future project sites.
Local Education
Invited faculty and students from Chang Jung Christian University and Kunshen Elementary School, as well as residents from the Jiangjun District, to visit the Qigu “Ri-Yun Aquaculture Co-generation Site.”
Employee Learning
Employees participated in on-site learning to deepen their understanding of the aquaculture co-generation model, including ecological education activities and an oyster-shell wind chime DIY workshop that strengthened their awareness of local community sustainability.
Delegation Visits
Hosted a delegation from the Ministry of Agriculture of Romania at the Ri-Yun site to showcase local community sustainability achievements. Additional international visits included groups from the Philippines, Indonesia, Japan, and Canada—receiving a total of eight foreign delegations.
