Compared to the conventional floating PV systems used in Singapore in calmer water bodies such as reservoirs, the membrane-based PV system is designed based on floating PV specialist Ocean Sun’s technology to harness solar energy reliably amid stronger waves and rougher sea conditions in a nearshore marine environment. This is achieved by attaching solar panels directly onto large circular reinforced membranes protected by a high-density polyethylene pipe structure surrounding the membrane, which creates a stable and safe platform.
The pilot PV system consists of three circular platforms, which will have an installed capacity of 1.5 MWp when deployed in the seawater surrounding Jurong island. The circular reinforced membranes for the PV panels ensure the lowest material usage of any floating PV system, enabling a lower Levelised Cost of Energy (LCOE) as well as resource conservation. The system is easy to deploy and install, and features increased efficiency from direct water cooling.
Expected to be ready in 4Q 2023, it will serve as a model for future scaling and replication in nearshore waterbodies in Singapore as well as overseas.
Ms Janice Bong, Executive Director, Power & Renewables, Keppel Infrastructure said, “We are pleased that the innovative floating solar PV system has been selected to help catalyse the deployment of renewable energy using unutilised sea space around Jurong Island. With the limited space Singapore has for solar panel deployment, the robust and innovative system can be easily scaled up and significantly increase the supply of floating solar power in Singapore to beyond just the deployment in reservoirs.
“This pilot innovation is in line with our commitment to support the energy transition through providing renewables, clean energy and decarbonisation solutions as part of Keppel’s Vision 2030 which puts sustainability at the core of the Group’s strategy.”
The award is part of EMA and JTC’s Jurong Island Renewable Energy Request for Proposals to accelerate the development of clean energy innovations for implementation on the island. Projects will be funded by a S$6 million joint commitment by EMA and JTC, with support from Enterprise Singapore.
The abovementioned transaction is not expected to have any material impact on the earnings per share and net tangible asset per share of Keppel Corporation Limited for the current financial year.
