The projects will use solar and battery energy storage systems in Johor.

The approvals were given to Sembcorp Utilities for 300MW and Southern Solar Alliance for 600MW.

Both companies plan to start commercial operations around 2029.

Before that, they must get regulatory approvals, finalize power purchase agreements, get financing, and meet key milestones.

Sembcorp will generate power from a floating solar and battery energy storage project at Linggiu Reservoir in Johor.

The project will use existing and future subsea infrastructure to facilitate cross-border power flows.

The approvals come as Singapore and Malaysia increase energy cooperation, including a plan to import 1 gigawatt of low-carbon electricity from Sarawak.

To date, the Energy Market Authority has given conditional approvals to 13 electricity import projects from several countries.

The agency will continue to work with companies that have credible and viable import proposals to decarbonize the power sector.

The approvals are part of Singapore's strategy to decarbonize its power sector through low-carbon electricity imports, which currently accounts for 40% of Singapore's carbon emissions.

Singapore aims to import about 6 gigawatts of low-carbon electricity by 2035, which is about one-third of its energy demand.
