Singapore’s 2026 Cross-Border Energy Strategy: A New Blueprint for Land-Constrained Solar Markets

Singapore’s Cross-Border Energy Imports: Shifting from Concept to Commercial-Scale Projects in 2026

Singapore is operationalizing a cross-border energy import strategy to overcome domestic land constraints, a tactical shift from early-stage bilateral agreements between 2021 and 2024 to concrete project approvals and large-scale corporate offtake agreements beginning in 2025.

• Between 2021 and 2024, Singapore’s external energy strategy was characterized by foundational agreements, such as the March 2023 MOU with Indonesia to explore developing up to 1.2 GW of solar for export. By contrast, the period from 2025 has seen these concepts mature into actionable policy, with Singapore’s government raising its low-carbon electricity import target to 6 GW by 2035.
• The most significant validation of this strategy occurred in October 2024, when the Sun Cable project, known as the Australia-Asia Power Link (AAPower Link), received conditional approval from Singapore. This marked a critical transition from ambition to a commercially viable project intended to supply up to 15% of the nation’s electricity via a 4, 300 km undersea cable.
• Corporate demand now underpins the bankability of these large-scale energy plans. While earlier periods saw public sector tenders like Solar Nova driving domestic growth, the August 2024 PPA between Microsoft and EDP Renewables for the entire output of the Solar Nova 8 project demonstrates the scale of private sector offtake needed to secure financing for both domestic and future import projects.

Financing the Grid Beyond Borders: Key Investments in Singapore’s Regional Energy Hub Strategy

Investment patterns have shifted from solely funding domestic solar assets to financing the specialized vehicles and regional project development pipelines required to execute Singapore’s cross-border energy import strategy.

• The Green Investment Partnership (GIP), part of Singapore’s broader FAST-P framework, exemplifies this shift by attracting foreign capital for regional deployment. The US$60 million commitment from British International Investment (BII) in October 2025 is designed to scale climate finance across Southeast Asia, creating the ecosystem needed to build export-oriented projects.
• Direct investment into regional project developers is accelerating, as shown by the US$80 million financing facility secured by ib vogt Singapore in March 2025. This capital, provided by Pentagreen Capital and BII, is explicitly targeted at developing new greenfield solar and battery storage projects across Southeast Asia, which can feed into Singapore’s import market.
• The growing complexity of financing cross-border assets has created a market for specialized fintech solutions. The December 2025 investment by ADB Ventures and Beacon VC into Quantified Energy, a startup focused on de-risking solar asset financing, highlights the need to build a sophisticated financial technology layer to support the physical infrastructure.

• The partnership model has matured from exploratory government-to-government MOUs to concrete infrastructure projects. The AAPower Link project, a partnership involving the governments of Singapore and Australia, advanced from a long-term concept to a project with conditional approval in October 2024, representing the most ambitious cross-border energy partnership in the region.
• Multi-national development consortiums are now forming specifically to supply the Singaporean market. The March 2023 agreement to develop up to 1.2 GW of solar in Indonesia for export involves a powerful consortium of state-owned and private entities, including Abu Dhabi’s Masdar, France’s EDF Renewables, Singapore’s Tuas Power, and Indonesia Power.
• Corporate power purchase agreements have become a critical lynchpin for these partnerships. Microsoft’s 20-year PPA with EDP Renewables for the Solar Nova 8 project, signed in August 2024, provides the revenue certainty that underpins large-scale project financing and serves as a model for future cross-border offtake agreements.

Expanding the Grid: Singapore’s Solar Strategy Redraws the Energy Map of Southeast Asia

Singapore’s energy geography is actively expanding beyond its physical borders, establishing Australia and Indonesia as key external power generation zones to meet its domestic decarbonization targets, a marked evolution from its internally focused strategy pre-2025.

• Between 2021 and 2024, Singapore’s strategy was almost exclusively focused on maximizing domestic surfaces. This was defined by scaling the Solar Nova program across public housing rooftops and pioneering large-scale floating solar with the 60 MWp Sembcorp Tengeh Floating Solar Farm.
• From 2025, the strategic geography has fundamentally shifted outward. While domestic deployment continues with an increased national target of 3 GWp by 2030, the primary mechanism for large-scale capacity growth is now through securing supply from neighboring countries with abundant land.
• Australia and Indonesia have emerged as the first two pillars of this external strategy. The AAPower Link project aims to connect Singapore to Australia’s vast solar resources, while multiple MOUs signed in 2023 position Indonesia’s Riau Islands as a dedicated “solar farm” for the Singaporean grid.

From Rooftops to Subsea Cables: Singapore’s Solar Technology Mix Matures Towards Grid Integration

While Singapore’s domestic solar growth is built on mature rooftop and floating PV technologies, its ambitious cross-border strategy introduces a new dependency on the successful commercial deployment of complex, large-scale transmission infrastructure like high-voltage direct current (HVDC) subsea cables.
