Ge Jenbacher has done a lot of effort investing and researching during the past years and through its continuous effort GE Jenbacher engines remain the market leaders in the field of cogeneration. The GE Jenbacher’s engines are highly efficient in converting energy into heat, cooling as well to electrical power from suitable gases. If there is a need for local use of heat, the alternative configuration of the engine so as to produce heat and power can be a major advantage.


Benefits of High Efficiency Electrical Power


GE Jenbacher’s engines high efficiency means:

  • Reduced levels of fuel consumption

  • Reduced emissions

  • Reduced operational costs for each kilowatt hour generated


Electricity Production


In order to produce electricity, a GE Jenbacher engine is connected to an electrical generator by a drive coupling, typically as a genset. The generator is then cabled to an electrical circuit breaker to connect it to the site electrical system. The circuit breaker is used to synchronize the generator to the mains if it is to operate in parallel to the grid supply. Regardless of the load, the engine rotates at a constant 1500 rpm. The generator has 4 poles which operate at 50Hz and at 1500 rpm to match the frequency of the mains.


Types of Electrical Generator


Electrical generation plants are usually constructed in two main forms:

  • Stable base load (continuous) generation

  • Electricity peaking


Base-load electricity


Base-load generation is useful to power the generators where there is a stable source of fuel, such as natural gas, landfill gas or coal gas. GE Jenbacher gas engines are known for their reliability in the field and when they operate with difficult gases. The generation of electricity alone typically takes place where there is no local need for heating and cooling. The power that is produced can either be exported to the local electricity grid, or alternatively be used in island mode operation to power local facilities.


Electrical peaking stations


Electricity peaking stations, commonly known also as peak-lopping plants, are power plants designed to help balance the fluctuating power requirements of the electricity grid. Typically, peaking stations operate in standby mode and then, when there is a peak in demand for power from the electricity grid; the gas engines receive a signal to commence operation. They are able to provide a rapid response to the fluctuating demand due to their flexibility and robustness. Then, as demand reduces, they are turned off.
