Energy & Rapid Transit Hub

The Energy & Rapid Transit Hub aspires to be a Centre of Excellence in learning and development of latest technologies in renewable energy, energy efficiency, electrical power systems, green transportation and rapid transit system

About the Tech hub 

The Energy & Rapid Transit Hub is equipped with solar and wind power stations and modern smart power networks (microgrids and smart grid) to provide students with a platform on which they can learn and build up capabilities and skills in the design, operation and maintenance of various energy systems through hands-on exercises or final year projects.  The hub also has a Rail System Simulator that is designed to train and equip students with technical skills and competencies for the relevant functions of the railway operations.  The simulator covers various technical operations, maintenance and management of rail transit system including train control system, signal & communication system, traction power system and integrated control system.

The hub seeks collaboration with industry and academic/research institutes in joint R&D and industry projects involving staff/students to improve competencies in the area of renewable energy applications, energy efficiency, microgrids, smart grid, green transportation, rapid transit technology, etc.  In addition, the hub also provide customised courses to retrain and upgrade manpower for electrical power and renewable energy industries.

Capabilities and Technical Services

The hub specialise in R&D and applied projects in the following technology areas:

  • Consultancies in power and energy systems and green transportation
  • Project development in emerging technologies in the areas of solar photovoltaic, wind energy, microgrids and smart grids, electrical power systems, green transportation systems, rapid transit technologies, etc.

Backed by the vast experience of the members, the centres have been providing technical consultation, training, seminars and project collaboration to the local government, education institutions, businesses and industry.

Project Showcase

The Energy & Rapid Transit Hub promotes a wide array of applied R&D projects undertaken by students and staff. Some of the achievements and past projects are shown below:

  • DC Microgrid System for Smart Grid Performance Enhancement

This is Singapore government (EMA) funded R&D project in collaboration with Singapore Power SP PowerGrid Ltd. The project aims to develop an intelligent, modularly designed grid-connected DC microgrid control system. Such a system minimizes the negative impact of the distributed renewable energy that are generated from solar PVs and wind turbines, and enhances smart grid performance in terms of system efficiency, stability and reliability through the developed smart power management units and system controllers.


  • AC/DC Hybrid MicroGrid System

MicroGrid system, a modern concept for a small-scale localized electricity generation and distribution system, has been developed and operated by students in SP. The system, integrating different energy sources and energy storages, is able to operate in two different modes: "island" mode" and "grid-connected" mode to provide both 240 VAC and 24 VDC electrical power in a lab setup.


  • Mobile MicroGrid Management System

This is Singapore government (MOE) funded R&D project in collaboration with ST Kinetics Ltd. The project aims to develop a standalone mobile power network management system that is capable of integrating multiple small generator sets as well as small renewable energy resources. This is done through smart controls with power electronics-based converters, resulting in a mobile microgrid power system with high power capacity and energy efficiency.

  • Development of IOT Technologies for Smart Facility Management

This is an SP Iconic Project funded fully by Singapore Polytechnic. The project aims to develop IOT technologies with emphasis on energy efficiency. Solutions under development include real-time tracking of electrical power consumption and environmental conditions like temperature, humidity, CO2 in a workspace. Based on these data collected, a climate control system is under development to optimise energy consumption.

  • Development of an Integrated Solar Photovoltaic-thermal (PVT) Module for the Tropics

This is Singapore government (MOE/EDB) funded R&D project in collaboration with Grenzone Pte Ltd and NUS.  The project aims to design and develop a novel and compact PVT collector and its smart management system that integrates solar PV and solar thermal systems to achieve improved overall energy efficiency and energy density.


  • 4.6kW Solar-Wind-Hybrid Standalone System

This system is for research on solar and wind hybrid operation. It is composed of the following: 2.1kW solar PV system, 2.5kW wind generator and energy storage. The system converts both solar and wind energy into electrical energy for electrical appliances in the laboratory or is stored in the battery bank.


  • 19.2kW Grid-connected Solar Photovoltaic System

This system is to study the performance of a PV system connected to the power grid. It consists of four 4.8kW mono-crystalline solar PV systems. The systems are connected to a low voltage grid and supply the power to the teaching blocks. The system has been operating successfully since its installation.


  • 48.88kW Solar Photovoltaic Test Bed (EDB CERT project)

The test bed consists of two different systems: one with 10 different PV technologies and another with 13 different installations. The main objectives of this EDB project are to study the performance of various PV technologies in the tropical region and to investigate the impact of different installations on the energy yield of PV system in Singapore.
