In November, 2011, Amazonas Energia signed a contract with GENRENT to modify the 140MW power plant in Manaus to operate on natural gas. In view of environmental concerns, the plant will be converted from diesel fuel to 70% natural gas and 30% diesel.

This conversion project is unique in terms of scope and technology and a result of close cooperation between GENRENT and engine manufacturer MTU. It will consist of 135 generators all powered by MTU and is expected to be completed in March 2012.
