Design, build, manage and operate biomass co-gen and tri-gen power plants that that enhances energy sustainability.
ecoWise invests, develops and manages renewable energy projects that yields significant environmental, social and economical benefits to the local community where it operates. The Group is one of the earliest companies in Singapore to focus on biomass power plant development.
Green Energy Hub @ Gardens by the Bay, Singapore
- An environmental sustainability concept where horticultural and other industrial wood wastes are utilized as biomass fuel to provide the required energy for daily operations.
- Tri-generation power plant which generates electrical power, heating (steam) and cooling services.
- The core of the biomass power plant is a very highly efficient biomass furnace and boiler system and it is one of the most efficient plant in the world operating more than 8,000 hours annually.
- Electrical power is produced through a steam turbine generator. Electricity is supplied directly to Gardens by the Bay’s power grid
- Hot water is generated from the turbine’s exhaust steam. The hot water is used by Gardens by the Bay in the regeneration of the liquid desiccant dryer (LDR) where the latter is utilized to create a dry atmosphere mimicking a temperate climate in the conservatories. Heat energy is also used in the operation of absorption chillers.
- Cooling load is generated through 2 units of absorption chillers. Cooling load is generated for the purpose of plant cooling and conservatories cooling (on demand)
- Sophisticated DCS process control system permits a lean O&M manpower requirement and ensures maximum operating efficiency
- Flue gas post treatment systems, consisting of cyclones and electrostatic precipitators ensures 100% compliance to air pollution control standards set by local authorities
- By-products such as fly ashes and bottom ashes are also repurposed as soil conditioner and eco concrete respectively.
