Port Electrification in Singapore

Summary

The Port of Singapore is the world's largest transshipment and bunkering hub. To maintain this leadership while meeting climate targets, the port is actively decarbonising its operations.

This briefing summarises the technical report by the Centre for Strategic Energy and Resources (CSER) on behalf of and in collaboration with T&E. We analyse the impacts of the current plan to electrify the Port of Singapore by 2050 against a Fully Electrified Port Scenario, with full electrification by 2035. In scope are the port cranes, automated guided vehicles (AGVs), and shoreside power for vessels.

Energy demand reduction of 430 GWh by 2030

Transitioning to a fully electrified port by 2035 would reduce total energy demand by 430 GWh compared to the reference case. However, this shift creates significant challenges for grid management. Without optimisation, peak hourly demand could hit 790 MWh by 2035, more than 3.5 times current levels, necessitating investment in battery storage and demand-side management.

Environmental and economic impact

Emissions Reductions: Full electrification could save up to 101 ktCO₂ annually by 2035. This also results in significant air quality improvements, including a projected cumulative reduction of 11.3 kt of NOx, 270 t of SOx, and 400 t of particulate matter.

Cost Efficiency: Cumulative energy costs are projected to be reduced by S$63 million annually by 2035. Furthermore, full electrification is estimated to save S$23 million in carbon taxes by 2035.

Investment Needs: Cumulative investments range from S$200 million (based on average annual power growth) to S$2,000 million (if peak load is unmanaged). While electrification requires significant upfront capital, incremental costs for port equipment can be recovered by 2030.

Policy recommendations:

Shoreside Power: A phased regulatory roadmap with supporting incentives would align all stakeholders

Grid Integration: A taskforce to align port planning with power system requirements could help ensure seamless coordination and delivery

Fiscal Policy: Strengthen carbon pricing and expand access to green finance to further help the economic case of electrification

Regional Leadership: Export standards to ASEAN and accelerate green corridors.
