GE completes world’s largest Jenbacher engine order
GE Energy just received its largest Jenbacher gas engines order in support of a major rural electrification initiative in Bangladesh. The order, from the Shahjibazar Power Company, is for 32 J620 GS Jenbacher engines and will help improve electricity in rural areas of the country that don’t have reliable transmission grids.
Jenbacher engines are known for their versatility and can run on either natural gas or a variety of other gases (e.g., biogas, landfill gas, coal mine gas, sewage gas, combustible industrial waste gases – to name a few) as well as special gas cases. What’s more impressive is that these gases often can come from sources of pure waste, like sewer sludge and cow manure.
Cow manure helping power towns and villages? Now that’s what I call waste to value.

Truly imagination @ work!
I’m curious how the efficiency of the Jenbacher engine (when it runs on ordinary natural gas) compares with high-end central station technology such as the GE "H" series turbines. I understand that in areas without a well-developed grid the Jenbacher may be a good solution, but I’m wondering how much these places will be able to upgrade their efficiency when they *do* have a grid in place.

Hi David,
Sorry for the delay. I checked with the GE Energy team:
The H System™ Combined Cycle Gas Turbines and Jenbacher reciprocating gas engines are two examples of GE Energy’s leading power generation technologies. As a part of a diverse energy portfolio, these technologies perform in the following ways to help meet the needs of our different customers:
Jenbacher reciprocating gas engines: The 624, our biggest natural gas Jenbacher engine, offers 4 megawatts (MW) of electrical output and 45% electrical efficiency. Natural gas reciprocating engines are mostly used for base load, decentralized co-generation application where electricity and heat is used.
H System™ Combined Cycle Gas Turbines: This gas turbine provides 400 – 500 MW of electricity at 55 – 60% electrical efficiency for utility and industrial projects such as Combined Cycle Power Plants.
GE recently announced that a large order of Jenbacher reciprocating gas engines was going to an independent power producer in Bangladesh. Short delivery time and low lifecycle costs (including high efficiency) were the main decision criteria for our customer in this order.
Hope that helps!
funny video. brilliant engineering concept. i’m glad that i am a GE investor. hat-tip to my 15 year old son!
What is instalad biogas engine in india
I wonder if 32 JGS620 is GEs biggest contract, then what would you say to 64 sets sale to Pakistan’s KESC gas power project, that they have successfully commissioned at Karachi, the Port city of Pakistan for the severe power shortage that we are facing here these days. The sets, installed in 2 sites, having 32 generators each have been commissioned and are in operation.
I guess the record is not yet updated.
I have not seen the video yet
This plant has replaced the old less efficient four turbnes of 24 MW (with out CPC) commisioned in 1978.
These 64 engines are installed for two sites of KESC called as KGTPS and SGTPS each having 32 sets to deliver 90MW of power to network.
Each site has four sections of 08 gensets delivering 22.5 MW to network through 30 MVA(11/132 KV) power transformer.
These both sites building construction, equipment installatin along with electrical and mechanical works,testing and commissioning took 09 month(last section#08 commissioned in nov 2009)and started sucessfully delivering full power capacity to KESC network.
That is reason this project won two awards fast track and finest project of the 2009 through autonomous body ASIA BANKOK.
Whole of the project completed under the engineering and contruction supervision of orient energy systems(sole distributer of GE in pakistan) with able guidance of GE teams support in various decipilines.
this plant is almost 2.5 times more efficient than the older one.
These smaller rating units(2.739MW) benefits more to owner in respect of the plant availability which usually remains 98 to 99% ensuring average efficiency of 40 to 41%.
As for as units operation and monitering are concerned these 32 units are monitered in central control room(CCR).
