Singapore–Indonesia Regional Power Grids: ESC’s Role in Enabling a Low-Carbon Future

Share this post

The ASEAN Power Grid is central to the region’s clean energy ambitions, linking countries through shared renewable resources and interconnected infrastructure. In Indonesia, the majority of electricity still comes from coal-fired power plants and other fossil fuels. Singapore, in contrast, produces little of its own power and depends heavily on imports. To accelerate decarbonisation and reduce greenhouse gas emissions in line with the Paris Agreement, Singapore’s Energy Market Authority (EMA) aims to import around 6 GW (gigawatts) of low-carbon electricity by 2035 – roughly one-third of its electricity demand. Much of this will come from cross-border electricity trade – a cornerstone in building regional power grids that connect nations and deliver clean, reliable power while supporting sustainable development goals.  

Building Regional Power Grids Between Singapore and Indonesia

One of the most ambitious initiatives in ASEAN’s clean energy transition is the Singapore–Indonesia renewable energy link. Designed to integrate Indonesia’s abundant renewable energy potential with Singapore’s growing low-carbon demand, the link channels clean electricity directly into Singapore’s grid. 

A dedicated corridor between the two nations could unlock multiple benefits for investors and developers: 

  • Stable, long-term access to green electricity for Singapore, mitigating supply risks and carbon exposure. 
  • Increased investment in renewable energy development and transmission for Indonesia, supporting economic growth and energy transition. 
  • Strengthened regional energy security and cross-border market integration. 

Policy alignment, technical standardisation, and environmental safeguards will be critical to ensuring projects deliver financial, social, and climate returns while promoting energy efficiency and grid stability. 

Investment and Market Outlook

The Singapore–Indonesia renewable energy corridor presents a compelling opportunity for investors, utilities, and infrastructure developers. Indonesia’s abundant solar, wind, geothermal, and hydropower resources, combined with Singapore’s growing appetite for low-carbon electricity, create a natural complementarity. Cross-border power trade can provide long-term, stable returns while supporting both countries’ decarbonisation goals and improving their power generation mix.

Regional cooperation also opens the door to innovative financing models, including green bonds and ESG-linked investment, while encouraging strategic infrastructure development in transmission and renewable generation. 

For investors, understanding the regulatory landscape and aligning projects with environmental and social standards will be key to capturing the corridor’s full potential. This includes considering the role of energy storage systems in enhancing grid reliability and supporting the integration of intermittent renewable sources. 

ESC’s Role in Enabling Cross-Border Energy Transition

Navigating cross-border renewable energy projects requires expertise in regulatory frameworks, environmental safeguards, and community engagement. ESC, a trusted environmental and social consultant with deep expertise in renewable energy in Singapore and Indonesia, helps clients’ advance initiatives that connect grids, enable solar imports, enhance water resilience, and embed sustainability throughout project delivery.

ESC’s teams also guide the preparation and implementation of environmental and social impact assessments (EIA/ESIA), ensuring projects meet regulatory requirements while addressing community and ecological concerns. This process involves comprehensive stakeholder engagement and capacity building to ensure local communities understand and benefit from these large-scale energy projects.

For example, ESC supported a 70 MW wind farm in Java, guiding environmental and social assessments to meet Indonesia’s renewable energy targets while ensuring community and regulatory alignment. This project also involved careful land use planning and biodiversity conservation measures to minimise ecological impacts.

In another instance, ESC facilitated permitting for the Australia–Asia PowerLink, ensuring subsea power cable approvals complied with environmental standards while connecting large-scale solar generation to Singapore’s grid. This project showcased ESC’s expertise in managing complex cross-border energy infrastructure and its ability to navigate the technical and regulatory challenges of subsea power transmission.

Even pilot projects, like a 300MW solar PV  installation in Batam, Indonesia, showcase ESC’s ability to manage cross-border environmental and social considerations while supporting clean power exports to Singapore. This innovative approach to solar deployment, which includes both land-based and subsea transmission cables, demonstrates the potential for combining renewable energy development with water resource management.

Across all these initiatives, ESC’s multidisciplinary teams translate local knowledge into practical solutions, helping investors and developers reduce risk while advancing sustainable energy infrastructure. Their work encompasses comprehensive studies to enable power import into Singapore. This includes strategic environmental assessments of competing sea corridors, as well as the development of mitigation measures to address potential impacts. 

Powering the Future Together

The Singapore–Indonesia regional power grids exemplify how cross-border collaboration can unlock both financial and sustainability value.

By integrating renewable energy resources, and ensuring sustainable project delivery, investors and infrastructure players can participate in a rapidly evolving low-carbon market with long-term potential. 

This energy transition mechanism not only supports the shift away from coal-fired power plants but also promotes energy diversification and enhances regional energy security. The development of cross-border electricity trade infrastructure creates new employment opportunities and fosters knowledge sharing between countries, contributing to a just transition in the energy sector. 

With decades of combined experience, ESC continues to guide stakeholders through complex cross-border energy transition projects, aligning technical, regulatory, and sustainability requirements to achieve successful outcomes. Their expertise in conducting feasibility studies, providing technical assistance, and facilitating development cooperation is crucial in realising the vision of an integrated ASEAN Power Grid.
