Smart Grid Management System, Pasir Panjang Terminal, Singapore
A strong Southeast Asian example is the Smart Grid Management System with battery Energy Storage System (ESS) at PSA’s Pasir Panjang Terminal in Singapore. (EMA, 2022; Onag, 2022)
Pasir Panjang is one of Singapore’s main container terminals, operated by PSA. In July 2022, the Energy Market Authority (EMA) and PSA announced an ESS at the terminal: a 2 MW/2 MWh lithium-ion battery integrated into a Smart Grid Management System (SGMS). The system, developed by a consortium led by Envision Digital under an SGD 8 million partnership between EMA and PSA, combines the ESS with solar panels and advanced energy-management software.

The SGMS uses machine learning on the EnOS platform to forecast terminal energy demand in real time, based on crane operations and other loads, and then optimizes when to charge or discharge the battery and when to draw from the grid. This allows the port to shave peaks caused by intensive container-handling, reduce overall electricity costs, and support wider grid stability by smoothing demand. It also creates a foundation for further electrification of port equipment by providing better visibility and control over energy flows. (Onag, 2022)
The ESS and SGMS are part of an SGD 8 million partnership between EMA and PSA to transform port-operations energy use through smart-grid technologies and energy-management systems. (EMA, 2022)
EMA states that the SGMS has the potential to improve the energy efficiency of port operations by about 2.5%, reducing the port's carbon footprint by roughly 1,000 tonnes of CO₂ equivalent per year, which is similar to removing around 300 cars from the road. When the ESS is not needed at the terminal, it will take part in the National Electricity Market of Singapore to provide ancillary services to the power grid and to generate revenue. Insights from the SGMS can also be applied to energy management at Tuas Port. (EMA, 2022; Onag, 2022)
Transferability
DMC ports planning to electrify cranes and other equipment can first monitor energy use to see when and where demand peaks. A battery paired with energy-management software can then shave peaks, lower electricity costs and support grid stability. Where market rules allow, the battery can earn revenue by serving the grid when the port does not need it. A partnership with the energy regulator or utility can help share the cost.
