This is an opportunity and a challenge to establish a climate resilience water supply portfolio for water security by Taiwan government. This study incorporated water production cost, intermittency cost, decarbonized cost, and available water from different sources under climate change, and to apply optimal control theory to establish a cost effectiveness model to plan a long-term (2031) climate resilience water supply portfolio in Taiwan. Furthermore, this research uses Penghu area as an empirical case study of water supply portfolio in 2031. The results showed that the desalination water will become the major source of water supply which accounts for 71.81% water supply share in 2031. However, high share of desalination water will result in significant increase on unit water production cost and carbon footprint. Therefore, water demand management is also needed and recommended to sustain water resources in Penghu area.
