About PSA International.

Formerly the Port of Singapore Authority, PSA International (PSA) is a leading port group, with >SGD 4B (USD 3B) in revenue (2019), >85M TEUs throughput, and a global network encompassing >50 locations in 26 countries around the world.

Beyond port operations, PSA also offers cargo solutions to customers operating in advanced manufacturing, cold chain, e-commerce, and energy & chemicals. PSA actively collaborates with customers and partners to deliver world-class port services, develop innovative cargo solutions, and co-create an Internet of Logistics.

PSA's Challenge.

As a leading port operator and global supply chain solutions provider, PSA needs to meet operational demands for energy efficiency in today’s fast-changing global landscape. It also needs to fulfil the sustainability agenda.

PSA’s Singapore port is one of the largest and busiest ports in the world with 24/7 operations. To optimize the way the port produces, consumes, and stores energy, plus accelerate its sustainability goals, PSA knew it needs next-level innovation to scale digitalization and transform the port for the future.

What PSA is Working Towards.

Envision Digital helps PSA build a Smart Grid that is intelligent and autonomous.

Become a smart and sustainable port with a Smart Grid.

Envision Digital helped PSA become a smart and sustainable port by deploying 5 smart energy applications that leverages EnOS™ AIoT platform. The applications – micro-grid control, energy efficiency management, virtual power plant (VPP), power trading and renewable energy certificate (REC) trading – will be implemented in 3 phases through Energy Orchestration, Machines Orchestration, and Systems Orchestration.

Achieve energy load optimization with Energy Orchestration.

With the micro-grid control, PSA can achieve energy load optimization using the port’s distributed photovoltaic (PV) assets, energy storage, and load-side equipment such as reefers & AGV. In addition, the energy efficiency management application will allow PSA to attain energy cost reduction per container.

Improve port operational efficiency with Machine Orchestration.

PSA’s operations were getting increasingly complex and would benefit from automation. By connecting to PSA operational systems, EnOS™ allows PSA to automate the maintenance scheduling of hundreds of quay cranes & rail gantry cranes without impacting day-to-day operations. This enabled intelligent, real-time collaboration across these machines to improve port operations.

Create new revenue streams with System Orchestration.

With VPP, PSA can now generate additional revenue by providing peak shaving and frequency regulation ancillary services for Singapore’s power grid. This is achieved through aggregating PSA's distributed energy resources and flexible load such as reefers and AGV, into a virtual power plant. VPP also offers PSA operational flexibility within its own port terminals to reduce and avoid uncontracted capacity charges.
