One main challenge faced by Singapore in constructing a new power plant is its land availability.

Another concern is that as a form of support in “green movement” stated in Paris Agreement, constructing a new fossil power plant must be limited. A solution that can be used to answer these problems is to import green (renewable) energy. Renewable energy is energy that is collected from renewable resources, which are naturally replenished on a human timescale, such as utilizing wind speed, solar power, and hydropower. In the other hand, Indonesia as a country located on the equator line, is rich in renewable energy sources such as solar. This creates a supply and demand condition. In other words, Indonesia can export its solar power to Singapore in order to fulfill its load growth. Two alternatives can be done to perform this energy export from Indonesia to Singapore. The first alternative is to built PV Farm in the nearest neighboring island with Singapore, namely Batam, Bintan, and Tanjung Balai Karimun regencies, then transfer the energy via submarine cable to Singapore. The second alternative is to built floating PV Farm on several lakes in Sumatra, gather the power via existing transmission system, then transfer it using submarine cable from Sumatra Landing Point located at the eastern coast of Riau to Singapore.
