Singapore grants conditional approval for 900 MW Malaysian renewable imports
Sembcorp and Ditrolic win clearance for solar and battery projects in Johor, targeting 2029 start-up.
Singapore's Energy Market Authority granted conditional approvals on Monday (2026-08-10) for two projects to import a combined 900 MW of electricity from Peninsular Malaysia, with Sembcorp Utilities securing 300 MW and Southern Solar Alliance, a Ditrolic Energy Holdings subsidiary, winning 600 MW. Both projects are scheduled to begin operations in 2029.3,4
The approvals advance Singapore's cross-border strategy to reduce reliance on piped gas. The EMA previously granted conditional approval for 1 GW of low-carbon electricity imports from Sarawak and is studying a second electricity interconnection of unspecified capacity.3,4
Ditrolic said on Monday (2026-08-10) its 600 MW project will anchor the first phase of the Southern Johor Renewable Energy Corridor, backed by roughly 4 GW-peak of solar generation capacity and 5.1 GWh of utility-scale battery energy storage in Malaysia's southern state. Close to 90% of the planned energy output has already attracted offtake interest from Singapore-based users in transport, airport and port operations, manufacturing, pharmaceuticals, logistics and real estate.3,4
The Malaysian supply route solves a land constraint. Singapore has limited space for large-scale solar or wind farms within its borders and relies overwhelmingly on natural gas for power generation. Importing from neighbouring jurisdictions with cheaper land and stronger solar irradiance offers a lower-cost path to renewable targets than domestic build-out.3
Battery storage at the source matters. Solar generation peaks midday; Singapore's demand peaks in the afternoon and early evening, when air conditioning loads rise. The 5.1 GWh of storage attached to Ditrolic's project would allow dispatch during local demand spikes, reducing the risk of curtailment and grid instability.3
Sembcorp has not disclosed project details beyond the 300 MW capacity. The company operates gas and solar assets in Singapore and has been expanding renewables capacity across Asia.3
Offtake interest ahead of final approval is unusual. Typically developers secure conditional regulatory nods before signing binding power purchase agreements with end-users. Ditrolic's claim that 90% of output is already spoken for suggests industrial and logistics customers are willing to commit early to lock in renewable supply, likely driven by corporate carbon targets or upcoming carbon border adjustment exposure.3
The 2029 target date matches the expiry of existing power contracts elsewhere in the region. Rio Tinto's Boyne aluminium smelter and Yarwun and Queensland alumina refineries in Australia face contract rollovers the same year, and a 1976-vintage coal plant supplying the smelter is slated to close then. Mining and heavy industry are emerging as anchor tenants for large renewable and storage hybrid projects.2
Australia's Capacity Investment Scheme Tender 7 awarded support in May (2026-05) for 7.8 GW of renewable generation, including six solar-plus-battery hybrid projects. The Birriwa project in New South Wales won backing for 600 MW of solar and 2,400 MWh of storage; Lightsource bp's Gundary project secured 320 MW of solar and 1,280 MWh of storage.1
The conditional nature of Singapore's approvals means Sembcorp and Ditrolic must still satisfy technical, financial and grid-integration requirements before final clearance. The projects also depend on Malaysia's regulatory framework for cross-border power exports and grid infrastructure upgrades on both sides of the causeway. Whether both reach commercial operation by 2029 will hinge on construction timelines and whether Malaysia prioritises the export corridor over domestic supply needs.3,4
