Information is Beautiful: New Gas Turbine Graphic Illuminates the Power of American Manufacturing

February 7, 2012

Natural gas packs a tremendous punch. Cleaner than oil and coal, it is already the world’s fastest growing fossil fuel. The U.S. Energy Information Administration estimates the global use of natural gas will double by 2035. GE’s American workers make many of the machines that unlock the power of this abundant natural resource and turn it into electricity for people and businesses around the world.

Today there are nearly 10,000 GE gas turbines installed around the world. GE’s Greenville, South Carolina, plant is the largest gas turbine manufacturing site in the world. It employs more than 3,000 workers who make the ecomagination-qualified Frame-7 turbines and other power equipment for customers in Europe, Asia and elsewhere in the world. The bulk of turbines they make travels abroad.

In Cincinnati, Ohio, home of GE’s aviation business, American workers make advanced gas turbines with “aeroderivative” jet engine technology at their core. Like their airborne brethren, these turbines are fast, powerful and flexible. They can start pumping out 50 megawatts of electricity in as little as 10 minutes. Today, nearly 2,300 aeroderivative turbines generate 80,000 megawatts of electricity in 73 countries.

This week GE released a data visualization that illustrates how these machines work. For two weeks, engineers collected information from 713 gas turbines. A team of graphic designers then plugged the measurements into a dynamic 3D graphic shown above. Each flash in the image represents a turbine turning on at some place in the world. This information is not just beautiful but also sparkles with insight. Take a look.

    ” …They can pump out over 50 megawatts of electricity in as little as 10 minutes…”

    Do you mean they can get up to 50MW power in ten minutes – or do you mean that they can deliver 50 megawatt-hours of energy in 10 minutes ?

    “… Today, some 2,000 aeroderivative turbines generate 2 million megawatts of electricity in 73 countries…”

    That works out to 1000 megawatts per turbine on average … that’s one heck of a power rating.

    Maybe you mean 1000 megawatt-hours per day? week? month ? year ? decade ?


    “This information is not just beautiful but also sparkles with insight”

    An amusing piece of art perhaps, but not informative.

    And “Gigawatts of energy” you say – maybe you mean gigawatt-hours of energy or gigawatts of power …

    All in all a pretty confused presentation; I bet someone at GE knows the difference between energy and power – perhaps you should pass such reports to Engineering before publication.

    @danS I believe they mean that the turbine can go from stopped to 50MW within 10 minutes of receiving a request to start, meaning that the turbine is able to rapidly respond to grid demand for power. I think your second point is spot-on regarding their math. No single gas turbine (to my knowledge) is able to produce 1 gigawatt. The statistic quoted was most likely intended to be total megawatt-hours produced over some period.

    Yes, well. I am sure there are GE engineers who cringed when they saw these same mistakes. On the other hand, I find the video rather entertaining in spite that.

    Thank you for your comments. You are correct, one gigawatt gas turbine would be a powerful machine. Today, nearly 2,300 aeroderivative turbines manufactured by GE generate 80,000 megawatts of electricity in 73 countries.
