Singapore s state-owned energy giant Sembcorp Industries and Malaysia’s Sarawak Energy recently announced that they have entered into a strategic agreement with Italian cable technology leader Prysmian Group, involving a subsea interconnection cable that will carry approximately 1 gigawatt (GW) of green power from Sarawak to Singapore.
The agreement, signed between Sembcorp Utilities, a wholly-owned power platform of Sembcorp Industries, and Sarawak Energy Services, a wholly-owned service subsidiary of Sarawak Energy, marks a key step towards regional energy interconnection in Southeast Asia.

Under the framework of the agreement, the partners will collaborate exclusively with Prysmian and technology partner SP PowerInterconnect to advance the design optimization, installation solution development and protection mechanism planning of the submarine interconnection cable. The cable system, designed for clean energy transmission, is expected to deliver about 1 gigawatt (GW) of green electricity from Sarawak, Malaysia to Singapore, equivalent to supporting the annual electricity needs of about 200,000 households. The implementation of the project needs to go through a multi-level regulatory approval process, and the parties have entered the stage of technical deepening.
In the announcement, Sembcorp Industries specifically pointed out that given that the project is still in the early development stage, it is not expected to have a material financial impact on the earnings per share and net tangible assets per share as of the end of the financial year 2025. This cross-border energy cooperation not only highlights the regional trend of collaborative development of renewable energy, but also highlights Prysmian’s leading position in the field of subsea HVDC transmission technology.
It is worth noting that Prysmian has recently accelerated the deployment of the European Energy interconnection network. In February this year, the company launched a new cable laying ship “Mona Lisa”, which immediately started the maritime interconnection project connecting the Italian mainland with Sicily and Sardinia. The project uses the latest generation of HVDC transmission technology, forming a technological linkage effect with the Southeast Asian project, further consolidating Prysmian’s strategic advantage in the global energy transmission field. According to industry analysts, the construction of such cross-border green energy corridors is not only in line with Singapore’s strategic goal of achieving 30% of imported electricity by 2030, but also helps Sarawak accelerate the development of rich hydropower and solar energy resources. With the acceleration of regional power market integration, more transnational energy interconnection projects may be spawned in the future
