Self sufficient Nigerian brewer uses 20 MW
July 11, 2012
These engines use natural gas, which is some 80% cheaper than diesel in Nigeria. Patrick Regan, global sales leader for GE Food and Beverage Solutions, says, “We can typically expect a gas engine like the one being installed in Lagos to pay for itself within just 18 to 24 months.”
The two new 3.3 MW CHP plants at the brewing plants will each feature a natural gas-powered Jenbacher J620 gas engine and a backup diesel engine from a different supplier. In 2008, Diageo first installed a Jenbacher J620 cogeneration unit at its Guinness Ogba brewery, where the system was connected to a waste-heat boiler to produce steam for the brewing process. The second installation in 2010 was configured to use the exhaust heat directly into an absorption chiller to provide a source of cooling for the plant. Also in 2008, Diageo installed its first two Jenbacher J620 cogeneration systems at its Guinness Benin City brewery. In addition to producing steam, the Benin City brewery’s Jenbacher unit was connected to an absorption chiller to create chilled water from the engine’s exhaust heat.
