A new round of rooftop solar systems is on the way to Singapore. Tokyo Electric Power Company Holdings (TEPCO) and logistics real estate group ESR are teaming up on this project. They’ve secured $9.5 million in funding from Taiwan’s Bank SinoPac to get started.
The project begins with 10 megawatts (MW) of solar panels spread across rooftops. Later, the plan is to grow the total capacity to 40 MW. The full loan agreement allows for up to $35 million in support.
This deal is a first for the TEPCO Group. The financing is being done through a special company set up just for this project, what’s known as a special purpose vehicle, or SPV.
TEPCO has bigger solar plans too. It wants to build 100 MW of rooftop systems across the Asia-Pacific region. In Singapore, the company has already signed agreements with electricity users who will buy the power directly.
There are also plans to move into Australia. TEPCO, through its TEPCO Global Energy unit, will explore using battery storage and smart energy management tools under what it calls the “TEPCO Area Energy Management” plan.
Beyond this partnership, smaller solar projects are also active in Singapore. On Pulau Ubin, a small island northeast of the mainland, a solar microgrid has been running since 2024. It powers homes and shops that aren’t connected to the main power network.
In Tuas, a logistics center installed a 2 MW rooftop solar system. The energy is used on-site to reduce electricity demand from the national grid. In Punggol, a few public housing blocks are testing 50-kilowatt solar systems. These panels power elevators, corridor lights, and water pumps.
Rooftop space is becoming more valuable in Singapore’s clean energy push. By early 2025, most of the country’s installed solar systems were already on roofs. The national rooftop solar capacity now exceeds 800 MW, and projects like TEPCO and ESR’s are expected to add to that total.
