Co-generation and Tri-generation

This is a combined heat and power generation system which can achieve very high energy conversion efficiency.

Conventional power generation energy efficiency is in the order of 30-35%. The efficiency of a co-generation plant normally varies from 70 to 85%. The greenhouse gas (CO2) emission per unit of power generated is therefore greatly reduced.

Depending upon the size (capacity) of the co-generation plant and utilisation factor of thermal energy the payback time of such a system varies from 4 to 8 years.

This is a capital intensive project. The cost of a typical smaller co-generation plant varies from 0.9 to 1.5 million Australian dollars per megawatt.

Who is suitable for Co-generation

Any industrial or commercial organisation, which uses a substantial amount of electricity as well as steam, hot water or process heating year round, is an ideal candidate for co-generation.

Typical organisations for co-generation

  • Food and Beverage Industry
  • Petrochemical and Oil Refinery
  • Pulp and Paper
  • Hospitals
  • Commercial buildings
  • Large Swimming Pools
  • Aquatic centres

Tri Generation

Tri-generation is an extension of co-generation. This typically produces power, hot water or steam for heating and chilled water or refrigerant for cooling.

Typically you can use

  • - Absorption chiller
  • - Adsorption chiller

Tri-generation is ideally suitable for business hotels where cooling and hot water heating is always required.

Today packaged co-generation systems are available in the market which include turbine, heat recovery and all necessary control gear to connect with the gridline. The advent of a micro turbine has made a very small co-generation system economically viable.

How can Enman help you?

  • Enman performs the preliminary and the detailed technical and economic studies.
  • Enman provide project engineering and management service for the implementation of a co-generation and tri-generation plant.

Government Subsidy

Currently government subsidies may be available both for the technical and economic feasibility studies as well as project implementation.
