Solutions

Cogent Energy uses natural gas-powered engines to generate on-site electricity. The waste heat from the engine is captured to provide heating (hot water or low grade steam), or for conversion to chilled water for cooling through an absorption chiller. When an absorption chiller is used, the solution is often referred to as trigeneration.

Flexible Packages

Cogent has developed scalable cogeneration and trigeneration packages starting from 400 kW up to 20 MW that are adaptable to most large site applications including commercial buildings, shopping centres, hotels, government buildings, hospitals and industry.

Our solution advantages include:

• Price competitive

  Cogent’s cost of energy (electricity, hot water and chilled water) is charged at rates that are price competitive to an equivalent accredited 50% GreenPower grid energy product (based on mid-2009 market rates).

• Environmental Benefits

  Cogent’s solution may reduce site carbon emissions by up to 50% compared to conventional brown coal-sourced grid energy, thereby having a significant impact on Green Star, NABERS energy and other industry carbon emission rating schemes. Cogent’s solution could improve commercial building Green Star and NABERS energy ratings by up to 2 stars depending upon configuration and application.

• Energy efficiency

  As waste heat from generating electricity is used for heating or producing chilled water, Cogent’s overall energy efficiency can exceed 80% and reduces the need and reliance on electric chillers and gas boilers.

• Emergency back-up

  Cogent’s solution can be configured to provide emergency back-up power in a similar way to diesel back-ups.

• Financed

  Cogent finances its onsite solution to reduce the up-front capital outlay by the site owner (compared to a traditional outright-purchase model). The site owner may need to conduct and fund some capital works to facilitate Cogent’s solution onsite.
